+ According to the CFF specification, charstrings can have up to 96 stem
+ hints. Due to hint replacement routines in Type 1 charstrings, some

- [autofit] Add blue-zone support for Sundanese script.
+ [sfnt] Fix charmap type 2 iterator (#52646).
- This essentially moves the Sundanese script from the `Indic' hinter
- to the `Latin' hinter.
+ The subsetted demo font of the report that exhibits the bug has a

+ code U+0131).
- * src/autofit/afblue.dat: Add blue zone data for Sundanese.

+ Fix access to uninitalized memory (#52613).
- Add new `slight' auto-hinting mode.
+ Also reported as
- This mode uses fractional advance widths and doesn't scale glyphs
- horizontally, only applying vertical scaling and hinting.
+ https://bugs.chromium.org/p/chromium/issues/detail?id=791317
- At the same time, the behaviour of the `light' auto-hinter gets
- restored for backward compatibility: Both vertical and horizontal
- scaling is again based on rounded metrics values (this was changed
- in a commit from 2017-03-30 as a side effect). To be more precise,
- the behaviour is restored for TrueType fonts only; for other font
- formats like Type 1, this is a new feature of the `light' hinting
- mode.

- [autofit] Prevent overlapping blue zones.
+ [psaux] Objects for new interpreter (part 2).
- Problem reported as
+ Make the new objects copy over values. They are essentially wrapper
+ types for the different decoders/builders.
- https://github.com/google/fonts/issues/632
+ * include/freetype/internal/psaux.h: Update declarations.
+ (PS_Builder): Add `is_t1' flag.
+ (PS_Decoder_{Get,Free}_Glyph_Callback): Renamed to...
+ (CFF_Decoder_{Get,Free}_Glyph_Callback: ... this.
+ (PS_Decoder): Updated.
+ Add `t1_parse_callback' member.
+ (PSAux_ServiceRec): Add `ps_decoder_init' member.
- The font in question (Nunito) has values 705 and 713 for the
- reference and overshoot values, respectively, of the first blue
- zone. Blue zone 2, however, has value 710 for both the reference
- and overshoot. At 12ppem, reference and overshoot of blue zone 0
- becomes 8px, while blue zone 2 becomes 9px.
+ * src/psaux/psdecode.h, src/psaux/psobjs.h: Update declarations.
- A peculiarity of this font is that the tops of isolated vertical
- stems like `N' have a slight overshoot also. The auto-hinter tries
- to find the nearest blue zone using the *original* coordinates. For
- vertical stems, this is value 713. For normal horizontal tops like
- in character `E', this is value 710. Since value 713 is mapped to
- 8px but value 710 to 9px, `N' and similar characters are one pixel
- higher than `E', which looks very bad.
+ * src/psaux/psdecode.c, src/psaux/psobjs.c: Implement copy with two
+ modes.
- This commit sanitizes blue zones to avoid such a behaviour.
+ * src/psaux/psauxmod.c: Add builder and decoder functions to `PSAux'
+ service.
- * src/autofit/aflatin.c (af_latin_sort_blue): New function.
- (af_latin_metrics_init_blues): Sort blue values and remove overlaps.

+ [psaux] Rename files.
- [autofit] Use better blue zone characters for lowercase latin.
+ Replace the `cf2' file name prefix with `ps' as the Adobe engine
+ will be used for both PostScript Types 1 and 2 (CFF) instead of just
+ CFF.
- The number of lowercase characters for computing the top flat blue
- zone value was too small (in most cases only `x' and `z'). If one
- of the two characters has a large serif, say, it can happen that
- FreeType must select between two different values, having a 50%
- chance to use the wrong one. As a result, rendering at larger PPEM
- values could yield uneven lowercase glyph heights.
+ s/cf2/ps/ for all following.
- Problem reported by Christoph Koeberlin <christoph@koe.berlin>.
+ * src/psaux/cf2*: Rename files.

+
+ Fix multiple calls of `FT_Bitmap_Convert'.
+
+ The documentation of `FT_Bitmap_Convert' says that multiple calls do
+ proper reallocation of the target FT_Bitmap object. However, this
+ failed for the sequence
+
+ non-empty bitmap
+ empty bitmap
+ non-empty bitmap
+
+ Reason was that `FT_Bitmap_Convert' only reallocated the bitmap
+ buffer if it became too small; it didn't make the buffer smaller.
+ For an empty bitmap following a non-empty one, only the buffer
+ dimension got set to zero, without deallocation. If the next call
+ was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was
+ triggered.

-2017-01-01 Werner Lemberg <wl@gnu.org>
+ This commit (mainly for 32bit CPUs) is the first of a series of
+ similar commits to handle known integer overflows. Basically, all
+ of them are harmless, since they affect rendering of glyphs only,
+ not posing security threats. It is expected that fuzzying will show
+ up more overflows, to be fixed in due course.
- [cff] Handle multiple `blend' operators in a row correctly.
+ The idea is to mark places where overflows can occur, using macros
+ that simply cast to unsigned integers, because overflow arithmetic
+ is well defined in this case. Doing so suppresses run-time errors
+ of sanitizers without adding computational overhead.

- [ftfuzzer] Restrict number of tested bitmap strikes.
+ [smooth] Implement minimal dynamic padding for LCD filtering.
- Malformed fonts often have large values for the number of bitmap
- strikes, and FreeType doesn't check the validity of all bitmap
- strikes in advance.
+ Extra bitmap padding for LCD filtering depends on the filter. The
+ default 5-tap filter needs 2 extra subpixels. The light 3-tap filter
+ needs only 1 extra subpixel. This space could be already available
+ due to rounding. In order to optimize the padding, we now expand
+ CBox for the given filter weights before rounding.

+ Add new `slight' auto-hinting mode.
- * src/sfnt/sfobjs.c (sfnt_init_face): If the axis count in `fvar' is
- zero, set `num_instances' to zero.

- * src/truetype/ttgxvar.c (TT_Get_MM_Var): Handle `fvar' table with
- zero axes as invalid.

+ restored for backward compatibility: Both vertical and horizontal
+ scaling is again based on rounded metrics values (this was changed
+ in a commit from 2017-03-30 as a side effect). To be more precise,
+ the behaviour is restored for TrueType fonts only; for other font

- This is a very old patch from openSuSE (from 2006, submitted to
- FreeType in 2011) that I forgot to apply.
+ For consistency, we always want the default instance in our list of

+ [autofit] Prevent overlapping blue zones.
- * Version 2.7 released.
- =======================
+ Problem reported as
+ https://github.com/google/fonts/issues/632
- Tag sources with `VER-2-7'.
+ The font in question (Nunito) has values 705 and 713 for the
+ reference and overshoot values, respectively, of the first blue
+ zone. Blue zone 2, however, has value 710 for both the reference
+ and overshoot. At 12ppem, reference and overshoot of blue zone 0
+ becomes 8px, while blue zone 2 becomes 9px.
- * docs/VERSION.TXT: Add entry for version 2.7.
+ A peculiarity of this font is that the tops of isolated vertical
+ stems like `N' have a slight overshoot also. The auto-hinter tries
+ to find the nearest blue zone using the *original* coordinates. For
+ vertical stems, this is value 713. For normal horizontal tops like
+ in character `E', this is value 710. Since value 713 is mapped to
+ 8px but value 710 to 9px, `N' and similar characters are one pixel
+ higher than `E', which looks very bad.

+ The number of lowercase characters for computing the top flat blue

+
+ [sfnt] Revert change from 2016-12-08.
+
+ I missed the functionality of `ft_module_get_service', which makes
+ the change unnecessary.
+
+2016-12-08 Werner Lemberg <wl@gnu.org>
+
+ Add framework to support services with 8 functions.
+
+ We will need this for CFF variation font support.
+
+ * include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC8):
+ New macro.
+
+2016-12-08 Werner Lemberg <wl@gnu.org>
+
+ [sfnt] Add `get_glyph_name' and `get_name_index' to SFNT interface.
+
+ CFF2 fonts will need access to those two functions.
+
+ * include/freetype/internal/sfnt.h: Include FT_SERVICE_GLYPH_DICT_H.
+ (SFNT_Interface): Add `get_glyph_name' and `get_name_index' members.
+ (FT_DEFINE_SFNT_INTERFACE): Updated.
+
+ * src/sfnt/sfdriver.c (sfnt_get_glyph_name, sfnt_get_name_index):
+ Fix signatures to exactly correspond to the glyph dict service
+ function typedefs.
+ (sfnt_interface): Updated.
+
+2016-12-06 Dave Arnold <darnold@adobe.com>
+
+ Add `FT_Get_Var_Design_Coordinates' function.
+
+ Note that the low-level functions aren't implemented yet.
+
+ * include/freetype/ftmm.h: Declare.
+
+ * include/freetype/internal/services/svmm.h
+ (FT_Get_Var_Design_Func): New typedef.
+ (MultiMasters): New MM service function `get_var_design'.
+ (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated.
+ Update all callers.
+
+ * src/base/ftmm.c (FT_Get_Var_Design_Coordinates): Implement.
+
+ * src/truetype/ttdriver.c: Updated.
+
+ * src/truetype/ttgxvar.c (TT_Get_Var_Design): New dummy function to
+ handle `get_var_design' service.
+ * src/truetype/ttgxvar.h: Updated.
+
+ * src/type1/t1driver.c: Updated.
+
+ * src/type1/t1load.c (T1_Get_Var_Design): New dump function to

+
+ [gzip] Improve building with external zlib (#49673).
+
+ Building FreeType with external zlib 1.2.8 makes msvc 14 stop with
+ the following error.
+
+ ftgzip.c
+ zlib-1.2.8\zlib.h(86): error C2061:
+ syntax error: identifier 'z_const'
+ zlib-1.2.8\zlib.h(94): error C2054:
+ expected '(' to follow 'z_const'
+ zlib-1.2.8\zlib.h(94): error C2085:
+ 'msg': not in formal parameter list
+ ...
+ zlib-1.2.8\zlib.h(877): fatal error C1003:
+ error count exceeds 100; stopping compilation
+
+ The error happens because FreeType keeps an own copy of zlib-1.1.4
+ under `src/gzip'. When building `src/gzip/ftgzip.c' with
+ FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses
+
+ #include <zlib.h>
+
+ which correctly finds an external `zlib.h', but `zlib.h' itself has
+ a line
+
+ #include "zconf.h"
+
+ which makes Visual Studio 2015 find `src/gzip/zconf.h' while
+ compiling the files in `src/gzip'.
+
+ * src/gzip/zconf.h: Rename to...
+ * src/gzip/ftzconf.h: ... this.
+ * src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated.

+
+ [autofit] Fix Emscripten crash (patch #9180).
+
+ Function calls through pointers must use a matching signature to
+ work on Emscripten, since such calls are dispatched through lookup
+ tables grouped by signature.
+
+ * src/autofit/aftypes.h (AF_WritingSystem_ApplyHintsFunc): Fix
+ typedef.
+

+
+2016-11-29 Werner Lemberg <wl@gnu.org>

+

+
+ [autofit] Code shuffling.
+
+ Also improve some comments and remove unused code.
+
+ No functional change.
+
+ * src/autofit/afloader.c (af_loader_load_g): Merged with...

+
+2016-11-17 Werner Lemberg <wl@gnu.org>
+
+ Better support of LLP64 systems with gcc (and clang).
+
+ * builds/unix/configure.raw: Call `AC_TYPE_LONG_LONG_INT'.
+
+ * builds/unix/ftconfig.in (FT_LONG64): Enable for LLP64 systems (and
+ suppress warnings) even without `FT_CONFIG_OPTION_FORCE_INT64'.
+
+2016-11-10 Werner Lemberg <wl@gnu.org>
+
+ Fix `lcd_weights' array size.
+
+ * include/freetype/internal/ftobjs.h (FT_LibraryRec): Do it.
+
+ Reported by Nikolaus.
+
+2016-11-06 Werner Lemberg <wl@gnu.org>
+
+ * src/base/ftobjs.c (FT_Render_Glyph_Internal): Fix tracing.
+
+2016-11-06 Werner Lemberg <wl@gnu.org>
+
+ [sfnt] Improve FT_LOAD_BITMAP_METRICS_ONLY for `sbix' format.
+
+ It's unavoidable to call the PNG engine, but to get the metrics it
+ is sufficient to read the PNG image's header only.
+
+ * src/sfnt/pngshim.c (Load_SBit_Png): Add argument to control the
+ allocation of the glyph slot.
+ * src/sfnt/pngshim.h: Updated.
+ * src/sfnt/ttsbit.c (tt_sbit_decoder_load_png,
+ tt_face_load_sbix_image, tt_face_load_sbit_image): Updated.
+
+2016-11-06 Werner Lemberg <wl@gnu.org>
+
+ [sfnt] Speed up `sbix' lookup.
+
+ This also fixes a bug introduced in 2016-10-01 which prevents
+ display of embedded bitmap fonts that use the `sbix' format.
+
+ * src/sfnt/ttsbit.c (tt_face_load_sbit): Store `sbix' size and
+ offset also in `ebdt_size' and `ebdt_start', respectively. This
+ makes the test for an embedded bitmap data table succeed for this
+ format.
+
+ (tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_SBIX>: Use
+ `ebdt_size' and `ebdt_start'
+ (tt_face_load_sbix_image): Ditto.
+
+2016-11-06 Seigo Nonaka <nona@google.com>
+ Werner Lemberg <wl@gnu.org>
+
+ Introduce a way of quickly retrieving (embedded) bitmap metrics.
+
+ `FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph
+ until the user calls `FT_Render_Glyph'. However, it always
+ allocates memory for bitmaps and copies or decodes the contents of a
+ bitmap glyph, which can be quite slow for PNG data.
+
+ * include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New
+ macro.
+
+ * src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if
+ FT_LOAD_BITMAP_METRICS_ONLY is used.
+
+ * src/sfnt/ttsbit.c (tt_sbit_decoder_alloc_bitmap,
+ tt_sbit_decoder_load_bitmap): Add argument to control allocation of
+ the glyph slot.
+ (tt_sbit_decoder_load_image, tt_sbit_decoder_load_compound,
+ tt_face_load_sbit_image): Updated.
+
+ * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Quickly exit if
+ `FT_LOAD_BITMAP_METRICS_ONLY' is set.
+
+ * src/pfr/pfrsbit.c, src/pfr/pfrsbit.h (pfr_slot_load_bitmap): Add
+ argument to control allocation of the glyph slot.
+ * src/pfr/pfrobjs (pfr_slot_load): Updated.
+
+ * src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto.
+
+ * docs/CHANGES: Updated.
+
+2016-11-06 Werner Lemberg <wl@gnu.org>
+
+ Synchronize with gnulib (#49448).
+
+ * include/freetype/config/ftconfig.h, builds/unix/ftconfig.in,
+ builds/vms/ftconfig.h (FT_TYPEOF): Update code to use definition in
+ current version of `intprops.h'.
+ Other minor synchronization to reduce code differences between the
+ three files.
+
+2016-11-03 Behdad Esfahbod <behdad@behdad.org>
+
+ [truetype] Clamp variation requests to valid range.
+
+ This is required by OpenType 1.8; it also avoids rounding surprises.
+
+ * src/truetype/ttgxvar.c (TT_Set_Var_Design): Clamp design coordinates
+ outside of the allowed range to always stay within the range instead
+ of producing an error.
+
+2016-10-29 Werner Lemberg <wl@gnu.org>

+ [pcf] Enrich family name with foundry name and glyph width info.
+
+ This is a very old patch from openSuSE (from 2006, submitted to
+ FreeType in 2011) that I forgot to apply.
+
+ https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch
+
+ Prepend the foundry name plus a space to the family name. There are
+ many fonts just called `Fixed' which look completely different, and
+ which have nothing to do with each other. When selecting `Fixed' in
+ KDE or Gnome one gets results that appear rather random, the style
+ changes often if one changes the size and one cannot select some
+ fonts at all.
+
+ We also check whether we have `wide' characters; all put together,
+ we get family names like `Sony Fixed' or `Misc Fixed Wide'.

+
+ [base] Avoid negative bitmap strike dimensions (#48985).
+
+ * src/base/ftobjs.c (FT_Open_Face): Check whether negation was
+ actually successful. For example, this can fail for value
+ -32768 if the type is `signed short'. If there are problems,

+
+ * docs/CHANGES: Updated.
+
+2016-09-01 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] Simplify span rendering more.
+
+ It turns out that there is significant cost associated with `FT_Span'
+ creation and calls to `gray_render_span' because it happens so
+ frequently. This removes these steps from our internal use but leaves
+ it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain
+ is about 5%.
+
+ * src/smooth/ftgrays.c (gray_render_span): Removed. The code is
+ migrated to...
+ (gray_hline): ... here.
+
+2016-08-30 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] Streamline pixmap drawing a bit more.
+
+ Zero coverage is unlikely (1 out of 256) to warrant checking. This
+ gives 0.5% speed improvement in rendering simple glyphs.
+
+ * src/smooth/ftgrays.c (gray_hline, gray_render_span): Remove checks.
+
+2016-08-29 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] Streamline pixmap drawing.
+
+ This gives 2% speed improvement in rendering simple glyphs.
+
+ * src/smooth/ftgrays.c (TPixmap): Reduced pixmap descriptor with a
+ pointer to its bottom-left and pitch to be used in...
+ (gray_TWorker): ... here.
+ (gray_render_span): Move pixmap flow check from here...
+ (gray_raster_render): .. to here.
+
+2016-08-27 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] Reduce stack of band boundaries.
+
+ * src/smooth/ftgrays.c (gray_TBand): Removed.
+ (gray_convert_glyph): Updated to stack band boundaries concisely.
+
+2016-08-26 Werner Lemberg <wl@gnu.org>
+
+ * src/cid/cidload.c (cid_face_open): Improve handling of `SDBytes'.
+
+2016-08-26 Werner Lemberg <wl@gnu.org>
+
+ [cid] Fix commit from 2016-05-16.
+
+ * src/cid/cidparse.c (cid_parser_new): Fix off-by-one errors.
+
+2016-08-26 Werner Lemberg <wl@gnu.org>
+
+ [sfnt] Cache offset and size to bitmap data table.
+
+ This commit avoids `EBDT' and friends being looked up again and
+ again while loading a single embedded bitmap.
+
+ * include/freetype/internal/tttypes.h (TT_FaceRec)
+ [TT_CONFIG_OPTION_EMBEDDED_BITMAPS]: New fields `ebdt_start' and
+ `ebdt_size'.
+
+ * src/sfnt/ttsbit.c (tt_sbit_decoder_init): Move table lookup to ...
+ (tt_face_load_sbit): ... this function; also store the table size
+ and offset.
+
+2016-08-26 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ * src/smooth/ftgrays.c (gray_raster_render): Minor tweaks.
+
+2016-08-26 Werner Lemberg <wl@gnu.org>
+
+ [type1] Fix heap buffer overflow.
+
+ Reported as
+
+ https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=36
+
+ * src/type1/t1load.c (parse_charstrings): Reject fonts that don't
+ contain glyph names.
+
+2016-08-25 Werner Lemberg <wl@gnu.org>
+
+ [sfnt] Fix previous commit (#48901).
+
+ * src/sfnt/ttcmap.c (tt_cmap4_char_map_binary): Thinkos.
+
+2016-08-25 Werner Lemberg <wl@gnu.org>
+
+ [sfnt] Speed up handling of invalid format 4 cmaps.
+
+ * src/sfnt/ttcmap.c (tt_cmap4_next, tt_cmap4_char_map_binary): Add
+ tests for `num_glyph' from `tt_cmap4_char_map_linear'.

+
+ * include/freetype/internal/ftdriver.h: Remove unused typedefs.
+
+2016-08-22 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] Simplify span rendering.
+
+ This removes unnecessary complexity of span merging and buffering.
+ Instead, the spans are rendered as they come, speeding up the
+ rendering by about 5% as a result.
+
+ * src/smooth/ftgrays.c [FT_MAX_GRAY_SPANS]: Macro removed.
+ (gray_TWorker): Remove span buffer and related fields.
+ (gray_sweep, gray_hline): Updated.
+
+ * include/freetype/ftimage.h: Remove documentation note about
+ `FT_MAX_GRAY_SPANS', which was never in `ftoption.h' and is now gone.
+
+2016-08-16 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix `MPS' instruction.
+
+ According to Greg Hitchcock, MPS in DWrite really returns the point
+ size.
+
+ * src/truetype/ttobjs.h (TT_SizeRec): Add `point_size' member.
+
+ * src/truetype/ttdriver.c (tt_size_request): Set `point_size'.
+
+ * src/truetype/ttinterp.h (TT_ExecContextRec): Add `pointSize'
+ member.
+
+ * src/truetype/ttinterp.c (TT_Load_Context): Updated.
+ (Ins_MPS): Fix instruction.
+
+2016-08-16 Werner Lemberg <wl@gnu.org>
+
+ [lzw] Optimize last commit.

+ [lzw] Avoid buffer overrun.
+
+ Reported as
+
+ https://bugzilla.mozilla.org/show_bug.cgi?id=1273283
+
+ * src/lzw/ftzopen.c (ft_lzwstate_refill): Ensure `buf_size' doesn't
+ underflow.

+
+ [winfonts] Avoid zero bitmap width and height.
+
+ Reported as
+
+ https://bugzilla.mozilla.org/show_bug.cgi?id=1272173
+
+ * src/winfonts/winfnt.c (FNT_Face_Init): Check zero pixel height.
+ (FNT_Load_Glyph): Check for zero pitch.
+
+2016-08-11 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ * src/truetype/ttinterp.c (Pop_Push_Count): Revert changes.
+
+2016-08-11 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ * src/truetype/ttinterp.c (TT_RunIns): Minor and formatting.

+
+2016-08-10 Werner Lemberg <wl@gnu.org>
+
+ [sfnt] Use correct type for `italicAngle' field (#48732).
+
+ * src/sfnt/ttload.c (tt_face_load_post): Fix types.
+
+2016-08-06 Jon Spencer <jon@jonspencer.ca>
+
+ [sfnt] Fix `FT_Get_Advance' for bitmap strikes.
+
+ `FT_Get_Advance' returns 0 for bitmap fonts. It first gets the
+ advance value from the font table and then scales it by the
+ `font->size->metrics->x_scale' field. But `FT_Select_Size' doesn't
+ set that value for bitmap fonts and the advance gets scaled to zero.
+
+ Taken from
+
+ https://github.com/behdad/harfbuzz/issues/252
+
+ * src/sfnt/ttsbit.c (tt_face_load_strike_metrics)
+ <TT_SBIT_TABLE_TYPE_EBLC>: Set scale values.
+
+2016-08-06 Behdad Esfahbod <behdad@behdad.org>
+
+ [truetype] Fix GX variation handling of composites.
+
+ * src/truetype/ttgload.c (load_truetype_glyph)
+ [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Check `ARGS_ARE_XY_VALUES' flag.
+
+2016-08-05 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] Minor refactoring.
+
+ * src/smooth/ftgrays.c (gray_render_scanline, gray_render_line):
+ Updated.
+
+2016-07-29 Werner Lemberg <wl@gnu.org>
+
+ [sfnt, truetype] Don't abort on invalid `maxComponentDepth'.
+
+ Since 2016-05-16 we detect infinite recursion directly.
+
+ * src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust
+ `maxComponentDepth'.
+ * src/truetype/ttgload.c (load_truetype_glyph): Don't abort if
+ `maxComponentDepth' is not valid. Instead, simply adjust its value
+ and emit a tracing message.
+
+2016-07-26 Werner Lemberg <wl@gnu.org>
+
+ * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Minor.
+
+ No functional change.
+
+2016-07-22 Hin-Tak Leung <htl10@users.sourceforge.net>
+
+ [truetype] Record the end of IDEFs.
+
+ To match the logic in FDEF. The value of the end is only used for
+ bound-checking in `Ins_JMPR', so it may not have been obvious that
+ it was not recorded. Tested (as part of Font Validator 2.0) all the
+ fonts on Fedora and did not see any change.
+
+ * src/truetype/ttinterp.c (Ins_IDEF): Updated.
+
+2016-07-19 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Sanitizer fix, second try.
+
+ * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary

+
+ * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Increase array
+ to fix nested loops.
+
+2016-07-18 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Make GETDATA work only for GX fonts.
+
+ * src/truetype/ttinterp.c (opcode_name): Updated.
+ (Ins_GETDATA): Only define for `TT_CONFIG_OPTION_GX_VAR_SUPPORT'.
+ (TT_RunIns): Updated.
+
+2016-07-17 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Add support for Apple's
+
+ GETDATA[], opcode 0x92
+
+ bytecode instruction. It always returns 17, and we have absolutely
+ no idea what it is good for...
+
+ * src/truetype/ttinterp.c (Pop_Push_Count, opcode_name): Updated.
+ (Ins_GETDATA): New function.
+ (TT_RunIns): Add it.
+
+2016-07-16 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Add bytecode support for GX variation fonts.
+
+ This commit implements undocumented (but confirmed) stuff from
+ Apple's old bytecode engine.
+
+ GETVARIATION[], opcode 0x91
+ This opcode pushes normalized variation coordinates for all axes
+ onto the stack (in 2.14 format). Coordinate of first axis gets
+ pushed first.
+
+ GETINFO[], selector bit 3
+ If GX variation support is enabled, bit 10 of the result is set
+ to 1.
+
+ * src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H.
+ (opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated.
+ (Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector
+ bit 3, checking support for variation glyph hinting.
+ (Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function
+ to implement opcode 0x91.
+ (TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91.
+
+2016-07-16 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix GETINFO bytecode instruction.
+
+ * src/truetype/ttinterp.c (Ins_GETINFO): Fix return value for
+ stretching information.
+
+2016-07-16 Behdad Esfahbod <behdad@behdad.org>
+
+ [truetype] Make all glyphs in `Zycon' GX font work.
+
+ * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary
+ tests.
+
+2016-07-16 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix GX delta tracing.
+
+ * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace
+ relative point movements.
+
+2016-07-16 Behdad Esfahbod <behdad@behdad.org>
+
+ [truetype] More fixes for GX.
+
+ This finally fixes the rendering of the cyclist and the lizard in
+ the `Zycon' font.
+
+ * src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point
+ index is always cumulative.
+
+ (tt_handle_deltas): Rename to...
+ (tt_interpolate_deltas): ... This.
+ Add new parameter for output point array.
+ Update caller.
+
+ (TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds
+ the intermediate results of `tt_interpolate_deltas' that are to be
+ added to `outline->points'.
+
+2016-07-15 Werner Lemberg <wl@gnu.org>
+
+ * src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko.
+
+ `max_pos' is always larger than `min_pos' so `FT_ABS' is not needed.
+
+ Reported by Alexei.
+
+2016-07-16 Nikolaus Waxweiler <madigens@gmail.com>
+
+ * src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error.
+
+ Problem reported by Hin-Tak Leung.
+
+2016-07-15 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Update and improve segment and edge tracing.
+
+ * src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace
+ `delta' also.
+ Don't show first point of segment as a replacement for `pos'; this
+ is (a) misleading, since the difference to `pos' can be almost
+ arbitrarily large in corner cases, and (b) it is better to have all
+ segment data in font units instead of a single value given in output
+ space coordinates.
+ Improve layout.
+ (af_glyph_hints_dump_edges): Show px->units and units->px conversion
+ values for convenience.
+ Improve layout.
+
+2016-07-15 Werner Lemberg <wl@gnu.org>
+
+ [autofit] For edges, reject segments wider than 1px (#41334).

+ (af_latin_hints_compute_edges): Reject segments with a delta larger
+ than 0.5px.
+
+2016-07-14 Werner Lemberg <wl@gnu.org>
+
+ * include/freetype/freetype.h (FT_IS_NAMED_INSTANCE): New macro.
+
+2016-07-14 Werner Lemberg <wl@gnu.org>
+
+ [sfnt] Fix `face_index' value in `FT_Face' for named instances.
+
+ * src/sfnt/sfobjs.c (sfnt_init_face): Don't strip off higher 16bits.
+
+2016-07-14 Werner Lemberg <wl@gnu.org>
+
+ * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing.
+
+2016-07-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [truetype] Fix gxvar delta interpolation.
+
+ The coordinates of the base font should be used for interpolation
+ purposes, NOT the current points (i.e., the result of accumulation
+ of previous deltas).
+
+ * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize
+ `points_org' before looping over all tuples.

+CHANGES BETWEEN 2.8.1 and 2.9
+
+ I. IMPORTANT BUG FIXES
+
+ - Advance width values of variation fonts were often wrong.
+
+ - More fixes for variation font support; you should update to this
+ version if you want to support them.
+
+
+ II. IMPORTANT CHANGES
+
+ - As a GSoC project, Ewald Hew extended the new (Adobe) CFF engine
+ to handle Type 1 fonts also, thus greatly improving the
+ rendering of this format. This is the new default. The old
+ engine is still available if the configuration macro
+ `T1_CONFIG_OPTION_OLD_ENGINE' gets defined; using the
+ `hinting-engine' property of the `type1' driver module you can
+ then switch between the two engines.
+
+ - A new function, `FT_Set_Named_Instance', can be used to set or
+ change the current named instance.
+
+ - Starting with this FreeType version, resetting variation
+ coordinates will return to the currently selected named
+ instance. Previously, FreeType returned to the base font (i.e.,
+ no instance set).
+
+
+ III. MISCELLANEOUS
+
+ - The `face_flags' field of the `FT_Face' structure has a new bit,
+ `FT_FACE_FLAG_VARIATION', which is set if a variation font has
+ been altered with `FT_Set_MM_Design_Coordinates',
+ `FT_Set_Var_Design_Coordinates', or
+ `FT_Set_Var_Blend_Coordinates'.
+
+ - If the current face is a named instance, the new macro
+ `FT_IS_NAMED_INSTANCE' returns true.
+
+ - `FT_IS_VARIATION' is a new macro that returns true whenever a
+ face object has been altered by `FT_Set_MM_Design_Coordinates',
+ `FT_Set_Var_Design_Coordinates', or
+ `FT_Set_Var_Blend_Coordinates'.
+
+ - Changing the design coordinates of a variation font with
+ `FT_Set_Var_Design_Coordinates' or
+ `FT_Set_Var_Blend_Coordinates' does not influence the named
+ instance index value (only `FT_Set_Named_Instance' does that).
+
+ - Special PostScript names for named instances are only returned
+ if the named instance is set with `FT_Set_Named_Instance' (and
+ the font has corresponding entries in its `fvar' table). If
+ `FT_IS_VARIATION' returns true, the algorithmically derived
+ PostScript name is provided, not looking up special entries for
+ named instances.
+
+ - A new function `FT_Done_MM_Var' is provided to free the memory
+ returned in a call to `FT_Get_MM_Var'.
+
+ - On platforms using the `configure' script, the installed
+ `ftoption.h' file now correctly reflects configuration options
+ like `--with-harfbuzz'.
+
+ - Better support to build FreeType as a DLL on Windows using
+ Visual C.
+
+ - All data specific to driver modules is now collected in a single
+ file, `FT_DRIVER_H'. Consequently, the macros
+ `FT_AUTOHINTER_H', `FT_CFF_DRIVER_H', `FT_TRUETYPE_DRIVER_H',
+ and `FT_PCF_DRIVER_H' still work but are deprecated.
+
+ - Some fuzzer fixes to better reject malformed fonts.
+
+ - The `ftbench' demo program has a new test for opening a new face
+ and loading some glyphs.
+
+ - The `ftbench' demo program has a new option `-j' to specify the
+ last glyph index to be used in the tests.
+
+ - The `ftgrid' demo program has a new option `-n' to suppress
+ display of named instances of variation fonts.
+
+ - The `ttdebug' demo program can now show a stack trace (key `K')
+ and switch between hexadecimal and decimal display of integers
+ (key `I').
+
+======================================================================
+
+CHANGES BETWEEN 2.8 and 2.8.1
+
+ I. IMPORTANT BUG FIXES
+
+ - B/W hinting of TrueType fonts didn't work properly if
+ interpreter version 38 or 40 was selected.
+
+ - Some severe problems within the handling of TrueType Variation
+ Fonts were found and fixed.
+
+ - Function `FT_Set_Var_Design_Coordinates' didn't correctly handle
+ the case with less input coordinates than axes.
+
+
+ II. IMPORTANT CHANGES
+
+ - By default, FreeType now offers high quality LCD-optimized
+ output without resorting to ClearType techniques of resolution
+ tripling and filtering. In this method, called Harmony, each
+ color channel is generated separately after shifting the glyph
+ outline, capitalizing on the fact that the color grids on LCD
+ panels are shifted by a third of a pixel. This output is
+ indistinguishable from ClearType with a light 3-tap filter.
+
+
+ III. MISCELLANEOUS
+
+ - Using the new function `FT_Get_Var_Axis_Flags', an application
+ can access the `flags' field of a variation axis (introduced in
+ OpenType version 1.8.2)
+
+ - More sanity checks.
+
+ - The internal representation of buffers for LCD rendering has
+ changed (to be more precise, the amount of padding gets computed
+ differently). Applications that use the FreeType API are not
+ affected.
+
+ - To reset all design axis values of a variation font to its
+ default values you can now say
+
+ error = FT_Set_Var_Design_Coordinates( face, 0, NULL );
+
+ This also works with functions `FT_Set_MM_Design_Coordinates'
+ and `FT_Set_MM_Blend_Coordinates'.
+
+ - FreeType now synthesizes a missing Unicode cmap for (older)
+ TrueType fonts also if glyph names are available.
+
+ - FreeType has improved handling of BDF fonts without the
+ `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties; the
+ library now uses the values of the `SIZE' keyword if they are
+ missing. Previously, `SIZE' was completely ignored, and
+ FreeType used heuristic values instead.
+
+ - Multiple calls to `FT_Bitmap_Convert' do work now as advertised.
+ Previously, they failed with an assertion error if there was an
+ empty bitmap between non-empty ones.
+
+ - The warping option has moved from `light' to `normal' hinting
+ where it replaces the original hinting algorithm. The `light'
+ mode is now always void of any hinting in x-direction.
+
+ - 16bit compiler support is now officially ended. We didn't
+ provide any maintenance since many years, and given that there
+ were no error or problem reports either it seems that it is no
+ longer needed.
+
+ - The `ftgrid' demo program can now toggle the display of grid
+ lines with the `G' key.
+
+ - The `ftgrid' demo program can toggle a different set of colors
+ (suitable to color-blind people) with the `C' key.
+
+ - The `ftgrid' demo program now supports the `-e' command line
+ option to select a cmap.
+
+ - The `ftdump' demo program has a new command line option `-t' to
+ output the SFNT table list.
+
+
+======================================================================
+
CHANGES BETWEEN 2.7.1 and 2.8
I. IMPORTANT CHANGES
configuration option. However, it is strongly recommended to
avoid that, adjusting font sizes instead.
+ - Global size metrics values in the `FT_Size_Metrics' structure
+ can be different for TrueType fonts. Reason is that in older
+ FreeType versions the metrics were rounded differently to
+ integer pixels compared to all other font formats, yielding an
+ inconsistent behaviour if you used non-native hinting. Starting
+ with this version, global size metrics for TrueType fonts are
+ handled the same as other font formats: `ascender' gets rounded
+ up, `descender' gets rounded down, `height' gets normally
+ rounded, and `max_advance' gets normally rounded, too.
+
+ If you need more precise values of (global) ascender, descender,
+ height, or `max_advance', please take the corresponding values
+ from the `FT_Face' structure and scale them manually.
+
- If a TrueType font gets loaded with FT_LOAD_NO_HINTING, FreeType
now scales the font linearly again (bug introduced in version
2.4.6).

<p>While FreeType's auto-hinter doesn't expose API functions by itself, it is possible to control its behaviour with <a href="ft2-module_management.html#FT_Property_Set">FT_Property_Set</a> and <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a>. The following lists the available properties together with the necessary macros and structures.</p>
<p>Note that the auto-hinter's module name is ‘autofitter’ for historical reasons.</p>

-<p><b>Experimental</b> <b>only</b></p>
-<p>The auto-hinter provides various script modules to hint glyphs. Examples of supported scripts are Latin or CJK. Before a glyph is auto-hinted, the Unicode character map of the font gets examined, and the script is then determined based on Unicode character ranges, see below.</p>
-<p>OpenType fonts, however, often provide much more glyphs than character codes (small caps, superscripts, ligatures, swashes, etc.), to be controlled by so-called ‘features’. Handling OpenType features can be quite complicated and thus needs a separate library on top of FreeType.</p>
-<p>The mapping between glyph indices and scripts (in the auto-hinter sense, see the <a href="ft2-auto_hinter.html#FT_AUTOHINTER_SCRIPT_XXX">FT_AUTOHINTER_SCRIPT_XXX</a> values) is stored as an array with ‘num_glyphs’ elements, as found in the font's <a href="ft2-base_interface.html#FT_Face">FT_Face</a> structure. The ‘glyph-to-script-map’ property returns a pointer to this array, which can be modified as needed. Note that the modification should happen before the first glyph gets processed by the auto-hinter so that the global analysis of the font shapes actually uses the modified mapping.</p>

-<p><b>Experimental</b> <b>only</b></p>
-<p>If FreeType gets compiled with option AF_CONFIG_OPTION_USE_WARPER to activate the warp hinting code in the auto-hinter, this property switches warping on and off.</p>
-<p>Warping only works in ‘light’ auto-hinting mode. The idea of the code is to slightly scale and shift a glyph along the non-hinted dimension (which is usually the horizontal axis) so that as much of its segments are aligned (more or less) to the grid. To find out a glyph's optimal scaling and shifting value, various parameter combinations are tried and scored.</p>

-<p>This property can be set via the ‘FREETYPE_PROPERTIES’ environment variable (using values 1 and 0 for ‘on’ and ‘off’, respectively).</p>
-<p>The warping code can also change advance widths. Have a look at the ‘lsb_delta’ and ‘rsb_delta’ fields in the <a href="ft2-base_interface.html#FT_GlyphSlotRec">FT_GlyphSlotRec</a> structure for details on improving inter-glyph distances while rendering.</p>
-<p>Since warping is a global property of the auto-hinter it is best to change its value before rendering any face. Otherwise, you should reload all faces that get auto-hinted in ‘light’ hinting mode.</p>

The side-effect is that glyphs ‘thin out’. Mac OS X and Adobe's proprietary font rendering library implement a counter-measure: stem darkening at smaller sizes where shades of gray dominate. By emboldening a glyph slightly in relation to its pixel size, individual pixels get higher coverage of filled-in outlines and are therefore ‘blacker’. This counteracts the ‘thinning out’ of glyphs, making text remain readable at smaller sizes. All glyphs that pass through the auto-hinter will be emboldened unless this property is set to TRUE.</p>
-<p>See the description of the CFF driver for algorithmic details. Total consistency with the CFF driver is currently not achieved because the emboldening method differs and glyphs must be scaled down on the Y-axis to keep outline points inside their precomputed blue zones. The smaller the size (especially 9ppem and down), the higher the loss of emboldening versus the CFF driver.</p>
-<p>This property can be set via the ‘FREETYPE_PROPERTIES’ environment variable similar to the CFF driver. It can also be set per face using <a href="ft2-base_interface.html#FT_Face_Properties">FT_Face_Properties</a> with <a href="ft2-auto_hinter.html#FT_PARAM_TAG_STEM_DARKENING">FT_PARAM_TAG_STEM_DARKENING</a>.</p>

If, for example, ‘encoding_id’ is ‘TT_MAC_ID_ROMAN’ and the language ID (minus 1) is ‘TT_MAC_LANGID_GREEK’, it is the Greek encoding, not Roman. ‘TT_MAC_ID_ARABIC’ with ‘TT_MAC_LANGID_FARSI’ means the Farsi variant the Arabic encoding.</p>

<p>Note that due to glyph hinting and the selected rendering mode these values are usually not exact; consequently, they must be treated as unreliable with an error margin of at least one pixel!</p>
<p>Indeed, the only way to get the exact metrics is to render <i>all</i> glyphs. As this would be a definite performance hit, it is up to client applications to perform such computations.</p>
<p>The ‘FT_Size_Metrics’ structure is valid for bitmap fonts also.</p>
+<p><b>TrueType</b> <b>fonts</b> <b>with</b> <b>native</b> <b>bytecode</b> <b>hinting</b></p>
+<p>All applications that handle TrueType fonts with native hinting must be aware that TTFs expect different rounding of vertical font dimensions. The application has to cater for this, especially if it wants to rely on a TTF's vertical data (for example, to properly align box characters vertically).</p>
+<p>Only the application knows <i>in</i> <i>advance</i> that it is going to use native hinting for TTFs! FreeType, on the other hand, selects the hinting mode not at the time of creating an <a href="ft2-base_interface.html#FT_Size">FT_Size</a> object but much later, namely while calling <a href="ft2-base_interface.html#FT_Load_Glyph">FT_Load_Glyph</a>.</p>

<p>‘FT_Open_Face’ and its siblings can be used to quickly check whether the font format of a given font resource is supported by FreeType. In general, if the ‘face_index’ argument is negative, the function's return value is 0 if the font format is recognized, or non-zero otherwise. The function allocates a more or less empty face handle in ‘*aface’ (if ‘aface’ isn't NULL); the only two useful fields in this special case are ‘face->num_faces’ and ‘face->style_flags’. For any negative value of ‘face_index’, ‘face->num_faces’ gives the number of faces within the font file. For the negative value ‘-(N+1)’ (with ‘N’ a non-negative 16-bit value), bits 16-30 in ‘face->style_flags’ give the number of named instances in face ‘N’ if we have a variation font (or zero otherwise). After examination, the returned <a href="ft2-base_interface.html#FT_Face">FT_Face</a> structure should be deallocated with a call to <a href="ft2-base_interface.html#FT_Done_Face">FT_Done_Face</a>.</p>

<h4>note</h4>
-<p>The LCD-optimized glyph bitmaps produced by ‘FT_Render_Glyph’ can be filtered to reduce color-fringes by using <a href="ft2-lcd_filtering.html#FT_Library_SetLcdFilter">FT_Library_SetLcdFilter</a> (not active in the default builds). It is up to the caller to either call ‘FT_Library_SetLcdFilter’ (if available) or do the filtering itself.</p>
+<p>Should you define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your ‘ftoption.h’, which enables patented ClearType-style rendering, the LCD-optimized glyph bitmaps should be filtered to reduce color fringes inherent to this technology. You can either set up LCD filtering with <a href="ft2-lcd_filtering.html#FT_Library_SetLcdFilter">FT_Library_SetLcdFilter</a> or <a href="ft2-base_interface.html#FT_Face_Properties">FT_Face_Properties</a>, or do the filtering yourself. The default FreeType LCD rendering technology does not require filtering.</p>
<p>The selected render mode only affects vector glyphs of a font. Embedded bitmaps often have a different pixel mode like <a href="ft2-basic_types.html#FT_Pixel_Mode">FT_PIXEL_MODE_MONO</a>. You can use <a href="ft2-bitmap_handling.html#FT_Bitmap_Convert">FT_Bitmap_Convert</a> to transform them into 8-bit pixmaps.</p>

<p><b>Hinting</b> <b>and</b> <b>antialiasing</b> <b>principles</b> <b>of</b> <b>the</b> <b>new</b> <b>engine</b></p>
<p>The rasterizer is positioning horizontal features (e.g., ascender height & x-height, or crossbars) on the pixel grid and minimizing the amount of antialiasing applied to them, while placing vertical features (vertical stems) on the pixel grid without hinting, thus representing the stem position and weight accurately. Sometimes the vertical stems may be only partially black. In this context, ‘antialiasing’ means that stems are not positioned exactly on pixel borders, causing a fuzzy appearance.</p>
<p>There are two principles behind this approach.</p>
<p>On the technical side, horizontal alignment zones for ascender, x-height, and other important height values (traditionally called ‘blue zones’) as defined in the font are positioned independently, each being rounded to the nearest pixel edge, taking care of overshoot suppression at small sizes, stem darkening, and scaling.</p>
<p>Hstems (this is, hint values defined in the font to help align horizontal features) that fall within a blue zone are said to be ‘captured’ and are aligned to that zone. Uncaptured stems are moved in one of four ways, top edge up or down, bottom edge up or down. Unless there are conflicting hstems, the smallest movement is taken to minimize distortion.</p>

-<p>Thanks to Adobe, which contributed a new hinting (and parsing) engine, an application can select between ‘freetype’ and ‘adobe’ if compiled with CFF_CONFIG_OPTION_OLD_ENGINE. If this configuration macro isn't defined, ‘hinting-engine’ does nothing.</p>
-<p>The default engine is ‘freetype’ if CFF_CONFIG_OPTION_OLD_ENGINE is defined, and ‘adobe’ otherwise.</p>

-<p>By default, the Adobe CFF engine darkens stems at smaller sizes, regardless of hinting, to enhance contrast. This feature requires a rendering system with proper gamma correction. Setting this property, stem darkening gets switched off.</p>
-<p>Note that stem darkening is never applied if <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_NO_SCALE</a> is set.</p>

-<p>By default, the Adobe CFF engine darkens stems as follows (if the ‘no-stem-darkening’ property isn't set):</p>
-<pre class="colored">
- stem width <= 0.5px: darkening amount = 0.4px
- stem width = 1px: darkening amount = 0.275px
- stem width = 1.667px: darkening amount = 0.275px
- stem width >= 2.333px: darkening amount = 0px
-</pre>
-<p>and piecewise linear in-between. At configuration time, these four control points can be set with the macro ‘CFF_CONFIG_OPTION_DARKENING_PARAMETERS’. At runtime, the control points can be changed using the ‘darkening-parameters’ property, as the following example demonstrates.</p>
-<pre class="colored">
- FT_Library library;
- FT_Int darken_params[8] = { 500, 300, // x1, y1
- 1000, 200, // x2, y2

- 2000, 0 }; // x4, y4
-
-
- FT_Init_FreeType( &library );
-
- FT_Property_Set( library, "cff",
- "darkening-parameters", darken_params );
-</pre>
-<p>The x values give the stem width, and the y values the darkening amount. The unit is 1000th of pixels. All coordinate values must be positive; the x values must be monotonically increasing; the y values must be monotonically decreasing and smaller than or equal to 500 (corresponding to half a pixel); the slope of each linear piece must be shallower than -1 (e.g., -.4).</p>

-<p>By default, the seed value for the CFF ‘random’ operator is set to a random value. However, mainly for debugging purposes, it is often necessary to use a known value as a seed so that the pseudo-random number sequences generated by ‘random’ are repeatable.</p>
-<p>The ‘random-seed’ property does that. Its argument is a signed 32bit integer; if the value is zero or negative, the seed given by the ‘intitialRandomSeed’ private DICT operator in a CFF file gets used (or a default value if there is no such operator). If the value is positive, use it instead of ‘initialRandomSeed’, which is consequently ignored.</p>

<h1 id="glyph_variants">Unicode Variation Sequences</h1>
<h2>Synopsis</h2>
<p>Many characters, especially for CJK scripts, have variant forms. They are a sort of grey area somewhere between being totally irrelevant and semantically distinct; for this reason, the Unicode consortium decided to introduce Variation Sequences (VS), consisting of a Unicode base character and a variation selector instead of further extending the already huge number of characters.</p>
<p>Unicode maintains two different sets, namely ‘Standardized Variation Sequences’ and registered ‘Ideographic Variation Sequences’ (IVS), collected in the ‘Ideographic Variation Database’ (IVD).</p>
-<p><a href="http://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt">http://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt</a> <a href="http://unicode.org/reports/tr37/">http://unicode.org/reports/tr37/</a> <a href="http://unicode.org/ivd/">http://unicode.org/ivd/</a></p>
+<p><a href="https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt">https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt</a> <a href="https://unicode.org/reports/tr37/">https://unicode.org/reports/tr37/</a> <a href="https://unicode.org/ivd/">https://unicode.org/ivd/</a></p>
<p>To date (January 2017), the character with the most ideographic variations is U+9089, having 32 such IVS.</p>
<p>Three Mongolian Variation Selectors have the values U+180B-U+180D; 256 generic Variation Selectors are encoded in the ranges U+FE00-U+FE0F and U+E0100-U+E01EF. IVS currently use Variation Selectors from the range U+E0100-U+E01EF only.</p>
<p>A VS consists of the base character value followed by a single Variation Selector. For example, to get the first variation of U+9089, you have to write the character sequence ‘U+9089 U+E0100’.</p>

<p>This section contains various functions used to perform so-called ‘incremental’ glyph loading. This is a mode where all glyphs loaded from a given <a href="ft2-base_interface.html#FT_Face">FT_Face</a> are provided by the client application.</p>
<p>Apart from that, all other tables are loaded normally from the font file. This mode is useful when FreeType is used within another engine, e.g., a PostScript Imaging Processor.</p>

-<p>Subpixel rendering exploits the color-striped structure of LCD pixels, increasing the available resolution in the direction of the stripe (usually horizontal RGB) by a factor of 3. Since these subpixels are color pixels, using them unfiltered creates severe color fringes. Use the <a href="ft2-lcd_filtering.html#FT_Library_SetLcdFilter">FT_Library_SetLcdFilter</a> API to specify a low-pass filter, which is then applied to subpixel-rendered bitmaps generated through <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>. The filter sacrifices some of the higher resolution to reduce color fringes, making the glyph image slightly blurrier. Positional improvements will remain.</p>
-<p>Note that no filter is active by default, and that this function is <b>not</b> implemented in default builds of the library. You need to #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your ‘ftoption.h’ file in order to activate it and explicitly call <a href="ft2-lcd_filtering.html#FT_Library_SetLcdFilter">FT_Library_SetLcdFilter</a> to enable it.</p>
+<p>Should you #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your ‘ftoption.h’, which enables patented ClearType-style rendering, the LCD-optimized glyph bitmaps should be filtered to reduce color fringes inherent to this technology. The default FreeType LCD rendering uses different technology, and API described below, although available, does nothing.</p>

The filter sacrifices some of the higher resolution to reduce color fringes, making the glyph image slightly blurrier. Positional improvements will remain.</p>
<p>A filter should have two properties:</p>
<p>1) It should be normalized, meaning the sum of the 5 components should be 256 (0x100). It is possible to go above or under this target sum, however: going under means tossing out contrast, going over means invoking clamping and thereby non-linearities that increase contrast somewhat at the expense of greater distortion and color-fringing. Contrast is better enhanced through stem darkening.</p>
<p>2) It should be color-balanced, meaning a filter ‘{ a, b, c, b, a }’ where a + b = c. It distributes the computed coverage for one subpixel to all subpixels equally, sacrificing some won resolution but drastically reducing color-fringing. Positioning improvements remain! Note that color-fringing can only really be minimized when using a color-balanced filter and alpha-blending the glyph onto a surface in linear space; see <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>.</p>

+
+<p>Thanks to Adobe, which contributed a new hinting (and parsing) engine, an application can select between ‘freetype’ and ‘adobe’ if compiled with CFF_CONFIG_OPTION_OLD_ENGINE. If this configuration macro isn't defined, ‘hinting-engine’ does nothing.</p>
+<p>The same holds for the Type 1 and CID modules if compiled with T1_CONFIG_OPTION_OLD_ENGINE.</p>
+<p>For the ‘cff’ module, the default engine is ‘freetype’ if CFF_CONFIG_OPTION_OLD_ENGINE is defined, and ‘adobe’ otherwise.</p>
+<p>For both the ‘type1’ and ‘t1cid’ modules, the default engine is ‘freetype’ if T1_CONFIG_OPTION_OLD_ENGINE is defined, and ‘adobe’ otherwise.</p>
+<p>The following example code demonstrates how to select Adobe's hinting engine for the ‘cff’ module (omitting the error handling).</p>

+
+<p>All glyphs that pass through the auto-hinter will be emboldened unless this property is set to TRUE. The same is true for the CFF, Type 1, and CID font modules if the ‘Adobe’ engine is selected (which is the default).</p>
+<p>Stem darkening emboldens glyphs at smaller sizes to make them more readable on common low-DPI screens when using linear alpha blending and gamma correction, see <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>. When not using linear alpha blending and gamma correction, glyphs will appear heavy and fuzzy!</p>
+<p>Gamma correction essentially lightens fonts since shades of grey are shifted to higher pixel values (= higher brightness) to match the original intention to the reality of our screens. The side-effect is that glyphs ‘thin out’. Mac OS X and Adobe's proprietary font rendering library implement a counter-measure: stem darkening at smaller sizes where shades of gray dominate. By emboldening a glyph slightly in relation to its pixel size, individual pixels get higher coverage of filled-in outlines and are therefore ‘blacker’. This counteracts the ‘thinning out’ of glyphs, making text remain readable at smaller sizes.</p>
+<p>By default, the Adobe engines for CFF, Type 1, and CID fonts darken stems at smaller sizes, regardless of hinting, to enhance contrast. Setting this property, stem darkening gets switched off.</p>
+<p>For the auto-hinter, stem-darkening is experimental currently and thus switched off by default (this is, ‘no-stem-darkening’ is set to TRUE by default). Total consistency with the CFF driver is not achieved right now because the emboldening method differs and glyphs must be scaled down on the Y-axis to keep outline points inside their precomputed blue zones. The smaller the size (especially 9ppem and down), the higher the loss of emboldening versus the CFF driver.</p>
+<p>Note that stem darkening is never applied if <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_NO_SCALE</a> is set.</p>

+<p>By default, the Adobe hinting engine, as used by the CFF, Type 1, and CID font drivers, darkens stems as follows (if the ‘no-stem-darkening’ property isn't set):</p>
+<pre class="colored">

+ stem width = 1.667px: darkening amount = 0.275px

+</pre>
+<p>and piecewise linear in-between. At configuration time, these four control points can be set with the macro ‘CFF_CONFIG_OPTION_DARKENING_PARAMETERS’; the CFF, Type 1, and CID drivers share these values. At runtime, the control points can be changed using the ‘darkening-parameters’ property, as the following example demonstrates for the Type 1 driver.</p>
+<pre class="colored">

+<p>The x values give the stem width, and the y values the darkening amount. The unit is 1000th of pixels. All coordinate values must be positive; the x values must be monotonically increasing; the y values must be monotonically decreasing and smaller than or equal to 500 (corresponding to half a pixel); the slope of each linear piece must be shallower than -1 (e.g., -.4).</p>

+
+<p>By default, the seed value for the CFF ‘random’ operator and the similar ‘0 28 callothersubr pop’ command for the Type 1 and CID drivers is set to a random value. However, mainly for debugging purposes, it is often necessary to use a known value as a seed so that the pseudo-random number sequences generated by ‘random’ are repeatable.</p>
+<p>The ‘random-seed’ property does that. Its argument is a signed 32bit integer; if the value is zero or negative, the seed given by the ‘intitialRandomSeed’ private DICT operator in a CFF file gets used (or a default value if there is no such operator). If the value is positive, use it instead of ‘initialRandomSeed’, which is consequently ignored.</p>

+<p>Color and Gray ClearType are the two available variants of ‘Y-direction ClearType’, meaning grayscale rasterization along the Y-direction; the name used in the TrueType specification for this feature is ‘symmetric smoothing’. ‘Classic ClearType’ is the original algorithm used before introducing a modified version in Win XP. Another name for v1.6's grayscale rendering is ‘font smoothing’, and ‘Color ClearType’ is sometimes also called ‘DWrite ClearType’. To differentiate between today's Color ClearType and the earlier ClearType variant with B/W rendering along the vertical axis, the latter is sometimes called ‘GDI ClearType’.</p>
+<p>‘Normal’ and ‘high’ sampling describe the (virtual) resolution to access the rasterized outline after the hinting process. ‘Normal’ means 1 sample per grid line (i.e., B/W). In the current Microsoft implementation, ‘high’ means an extra virtual resolution of 16x16 (or 16x1) grid lines per pixel for bytecode instructions like ‘MIRP’. After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid lines for color filtering if Color ClearType is activated.</p>
+<p>Note that ‘Gray ClearType’ is essentially the same as v1.6's grayscale rendering. However, the GETINFO instruction handles it differently: v1.6 returns bit 12 (hinting for grayscale), while v2.1 returns bits 13 (hinting for ClearType), 18 (symmetrical smoothing), and 19 (Gray ClearType). Also, this mode respects bits 2 and 3 for the version 1 gasp table exclusively (like Color ClearType), while v1.6 only respects the values of version 0 (bits 0 and 1).</p>
+<p>Keep in mind that the features of the above interpreter versions might not map exactly to FreeType features or behavior because it is a fundamentally different library with different internals.</p>

+
+<p>Currently, three versions are available, two representing the bytecode interpreter with subpixel hinting support (old ‘Infinality’ code and new stripped-down and higher performance ‘minimal’ code) and one without, respectively. The default is subpixel support if TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support otherwise (since it isn't available then).</p>
+<p>If subpixel hinting is on, many TrueType bytecode instructions behave differently compared to B/W or grayscale rendering (except if ‘native ClearType’ is selected by the font). Microsoft's main idea is to render at a much increased horizontal resolution, then sampling down the created output to subpixel precision. However, many older fonts are not suited to this and must be specially taken care of by applying (hardcoded) tweaks in Microsoft's interpreter.</p>
+<p>Details on subpixel hinting and some of the necessary tweaks can be found in Greg Hitchcock's whitepaper at ‘<a href="https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>’. Note that FreeType currently doesn't really ‘subpixel hint’ (6x1, 6x2, or 6x5 supersampling) like discussed in the paper. Depending on the chosen interpreter, it simply ignores instructions on vertical stems to arrive at very similar results.</p>
+<p>The following example code demonstrates how to deactivate subpixel hinting (omitting the error handling).</p>

+<p>The auto-hinter provides various script modules to hint glyphs. Examples of supported scripts are Latin or CJK. Before a glyph is auto-hinted, the Unicode character map of the font gets examined, and the script is then determined based on Unicode character ranges, see below.</p>
+<p>OpenType fonts, however, often provide much more glyphs than character codes (small caps, superscripts, ligatures, swashes, etc.), to be controlled by so-called ‘features’. Handling OpenType features can be quite complicated and thus needs a separate library on top of FreeType.</p>
+<p>The mapping between glyph indices and scripts (in the auto-hinter sense, see the <a href="ft2-properties.html#FT_AUTOHINTER_SCRIPT_XXX">FT_AUTOHINTER_SCRIPT_XXX</a> values) is stored as an array with ‘num_glyphs’ elements, as found in the font's <a href="ft2-base_interface.html#FT_Face">FT_Face</a> structure. The ‘glyph-to-script-map’ property returns a pointer to this array, which can be modified as needed. Note that the modification should happen before the first glyph gets processed by the auto-hinter so that the global analysis of the font shapes actually uses the modified mapping.</p>

+<p>Warping only works in ‘normal’ auto-hinting mode replacing it. The idea of the code is to slightly scale and shift a glyph along the non-hinted dimension (which is usually the horizontal axis) so that as much of its segments are aligned (more or less) to the grid. To find out a glyph's optimal scaling and shifting value, various parameter combinations are tried and scored.</p>

+<p>Behind the scenes, both drivers use the Adobe CFF engine for hinting; however, the used properties must be specified separately.</p>

<p>Possible values of the language identifier field in the name records of the SFNT ‘name’ table if the ‘platform’ identifier code is <a href="ft2-truetype_tables.html#TT_PLATFORM_XXX">TT_PLATFORM_MICROSOFT</a>.

<p>While FreeType's TrueType driver doesn't expose API functions by itself, it is possible to control its behaviour with <a href="ft2-module_management.html#FT_Property_Set">FT_Property_Set</a> and <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a>. The following lists the available properties together with the necessary macros and structures.</p>
<p>The TrueType driver's module name is ‘truetype’.</p>
+<p>A single property <a href="ft2-properties.html#interpreter-version">interpreter-version</a> is available, as documented in the ‘<a href="ft2-properties.html#properties">Driver properties</a>’ section.</p>
<p>We start with a list of definitions, kindly provided by Greg Hitchcock.</p>
<p><i>Bi-Level</i> <i>Rendering</i></p>
<p>Monochromatic rendering, exclusively used in the early days of TrueType by both Apple and Microsoft. Microsoft's GDI interface supported hinting of the right-side bearing point, such that the advance width could be non-linear. Most often this was done to achieve some level of glyph symmetry. To enable reasonable performance (e.g., not having to run hinting on all glyphs just to get the widths) there was a bit in the head table indicating if the side bearing was hinted, and additional tables, ‘hdmx’ and ‘LTSH’, to cache hinting widths across multiple sizes and device aspect ratios.</p>
<p><i>ClearType</i> <i>Subpixel</i> <i>Positioning</i></p>
<p>One of the nice benefits of ClearType is the ability to more crisply display fractional widths; unfortunately, the GDI model of integer bitmaps did not support this. However, the WPF and Direct Write frameworks do support fractional widths. DWrite calls this ‘natural mode’, not to be confused with GDI's ‘natural widths’. Subpixel positioning, in the current implementation of Direct Write, unfortunately does not support hinted advance widths, see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec22">http://www.beatstamm.com/typography/RTRCh4.htm#Sec22</a>. Note that the TrueType interpreter fully allows the advance width to be adjusted in this mode, just the DWrite client will ignore those changes.</p>
<p><i>ClearType</i> <i>Backward</i> <i>Compatibility</i></p>
-<p>This is a set of exceptions made in the TrueType interpreter to minimize hinting techniques that were problematic with the extra resolution of ClearType; see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec1">http://www.beatstamm.com/typography/RTRCh4.htm#Sec1</a> and <a href="http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>. This technique is not to be confused with ClearType compatible widths. ClearType backward compatibility has no direct impact on changing advance widths, but there might be an indirect impact on disabling some deltas. This could be worked around in backward compatibility mode.</p>

<p><i>Native</i> <i>ClearType</i> <i>Mode</i></p>
<p>(Not to be confused with ‘natural widths’.) This mode removes all the exceptions in the TrueType interpreter when running with ClearType. Any issues on widths would still apply, though.</p>

-<h3 id="interpreter-version">interpreter-version</h3>
-
-<p>Currently, three versions are available, two representing the bytecode interpreter with subpixel hinting support (old ‘Infinality’ code and new stripped-down and higher performance ‘minimal’ code) and one without, respectively. The default is subpixel support if TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support otherwise (since it isn't available then).</p>
-<p>If subpixel hinting is on, many TrueType bytecode instructions behave differently compared to B/W or grayscale rendering (except if ‘native ClearType’ is selected by the font). Microsoft's main idea is to render at a much increased horizontal resolution, then sampling down the created output to subpixel precision. However, many older fonts are not suited to this and must be specially taken care of by applying (hardcoded) tweaks in Microsoft's interpreter.</p>
-<p>Details on subpixel hinting and some of the necessary tweaks can be found in Greg Hitchcock's whitepaper at ‘<a href="http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>’. Note that FreeType currently doesn't really ‘subpixel hint’ (6x1, 6x2, or 6x5 supersampling) like discussed in the paper. Depending on the chosen interpreter, it simply ignores instructions on vertical stems to arrive at very similar results.</p>
-<p>The following example code demonstrates how to deactivate subpixel hinting (omitting the error handling).</p>

-<h4>note</h4>
-<p>This property controls the behaviour of the bytecode interpreter and thus how outlines get hinted. It does <b>not</b> control how glyph get rasterized! In particular, it does not control subpixel color filtering.</p>
-<p>If FreeType has not been compiled with the configuration option TT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version 38 or 40 causes an ‘FT_Err_Unimplemented_Feature’ error.</p>
-<p>Depending on the graphics framework, Microsoft uses different bytecode and rendering engines. As a consequence, the version numbers returned by a call to the ‘GETINFO’ bytecode instruction are more convoluted than desired.</p>
-<p>Here are two tables that try to shed some light on the possible values for the MS rasterizer engine, together with the additional features introduced by it.</p>
-<pre class="colored">
- GETINFO framework version feature
- -------------------------------------------------------------------
- 3 GDI (Win 3.1), v1.0 16-bit, first version
- TrueImage
- 33 GDI (Win NT 3.1), v1.5 32-bit
- HP Laserjet
- 34 GDI (Win 95) v1.6 font smoothing,
- new SCANTYPE opcode
- 35 GDI (Win 98/2000) v1.7 (UN)SCALED_COMPONENT_OFFSET
- bits in composite glyphs
- 36 MGDI (Win CE 2) v1.6+ classic ClearType
- 37 GDI (XP and later), v1.8 ClearType
- GDI+ old (before Vista)
- 38 GDI+ old (Vista, Win 7), v1.9 subpixel ClearType,
- WPF Y-direction ClearType,
- additional error checking
- 39 DWrite (before Win 8) v2.0 subpixel ClearType flags
- in GETINFO opcode,
- bug fixes
- 40 GDI+ (after Win 7), v2.1 Y-direction ClearType flag
- DWrite (Win 8) in GETINFO opcode,
- Gray ClearType
-</pre>
-<p>The ‘version’ field gives a rough orientation only, since some applications provided certain features much earlier (as an example, Microsoft Reader used subpixel and Y-direction ClearType already in Windows 2000). Similarly, updates to a given framework might include improved hinting support.</p>
-<pre class="colored">
- version sampling rendering comment
- x y x y
- --------------------------------------------------------------
- v1.0 normal normal B/W B/W bi-level
- v1.6 high high gray gray grayscale
- v1.8 high normal color-filter B/W (GDI) ClearType
- v1.9 high high color-filter gray Color ClearType
- v2.1 high normal gray B/W Gray ClearType
- v2.1 high high gray gray Gray ClearType
-</pre>
-<p>Color and Gray ClearType are the two available variants of ‘Y-direction ClearType’, meaning grayscale rasterization along the Y-direction; the name used in the TrueType specification for this feature is ‘symmetric smoothing’. ‘Classic ClearType’ is the original algorithm used before introducing a modified version in Win XP. Another name for v1.6's grayscale rendering is ‘font smoothing’, and ‘Color ClearType’ is sometimes also called ‘DWrite ClearType’. To differentiate between today's Color ClearType and the earlier ClearType variant with B/W rendering along the vertical axis, the latter is sometimes called ‘GDI ClearType’.</p>
-<p>‘Normal’ and ‘high’ sampling describe the (virtual) resolution to access the rasterized outline after the hinting process. ‘Normal’ means 1 sample per grid line (i.e., B/W). In the current Microsoft implementation, ‘high’ means an extra virtual resolution of 16x16 (or 16x1) grid lines per pixel for bytecode instructions like ‘MIRP’. After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid lines for color filtering if Color ClearType is activated.</p>
-<p>Note that ‘Gray ClearType’ is essentially the same as v1.6's grayscale rendering. However, the GETINFO instruction handles it differently: v1.6 returns bit 12 (hinting for grayscale), while v2.1 returns bits 13 (hinting for ClearType), 18 (symmetrical smoothing), and 19 (Gray ClearType). Also, this mode respects bits 2 and 3 for the version 1 gasp table exclusively (like Color ClearType), while v1.6 only respects the values of version 0 (bits 0 and 1).</p>
-<p>Keep in mind that the features of the above interpreter versions might not map exactly to FreeType features or behavior because it is a fundamentally different library with different internals.</p>

- * @property:
- * glyph-to-script-map
- *
- * @description:
- * *Experimental* *only*
- *
- * The auto-hinter provides various script modules to hint glyphs.
- * Examples of supported scripts are Latin or CJK. Before a glyph is
- * auto-hinted, the Unicode character map of the font gets examined, and
- * the script is then determined based on Unicode character ranges, see
- * below.
- *
- * OpenType fonts, however, often provide much more glyphs than
- * character codes (small caps, superscripts, ligatures, swashes, etc.),
- * to be controlled by so-called `features'. Handling OpenType features
- * can be quite complicated and thus needs a separate library on top of
- * FreeType.
- *
- * The mapping between glyph indices and scripts (in the auto-hinter
- * sense, see the @FT_AUTOHINTER_SCRIPT_XXX values) is stored as an
- * array with `num_glyphs' elements, as found in the font's @FT_Face
- * structure. The `glyph-to-script-map' property returns a pointer to
- * this array, which can be modified as needed. Note that the
- * modification should happen before the first glyph gets processed by
- * the auto-hinter so that the global analysis of the font shapes
- * actually uses the modified mapping.
- *
- * The following example code demonstrates how to access it (omitting
- * the error handling).
- *
- * {
- * FT_Library library;
- * FT_Face face;
- * FT_Prop_GlyphToScriptMap prop;

- * warping (omitting the error handling).

- * This property can be used with @FT_Property_Get also.
- *
- * This property can be set via the `FREETYPE_PROPERTIES' environment
- * variable (using values 1 and 0 for `on' and `off', respectively).
- *
- * The warping code can also change advance widths. Have a look at the
- * `lsb_delta' and `rsb_delta' fields in the @FT_GlyphSlotRec structure
- * for details on improving inter-glyph distances while rendering.
- *
- * Since warping is a global property of the auto-hinter it is best to

- * no-stem-darkening[autofit]
- *
- * @description:
- * *Experimental* *only*, *requires* *linear* *alpha* *blending* *and*
- * *gamma* *correction*
- *
- * Stem darkening emboldens glyphs at smaller sizes to make them more
- * readable on common low-DPI screens when using linear alpha blending
- * and gamma correction, see @FT_Render_Glyph. When not using linear
- * alpha blending and gamma correction, glyphs will appear heavy and
- * fuzzy!
- *
- * Gamma correction essentially lightens fonts since shades of grey are
- * shifted to higher pixel values (=~higher brightness) to match the
- * original intention to the reality of our screens. The side-effect is
- * that glyphs `thin out'. Mac OS~X and Adobe's proprietary font
- * rendering library implement a counter-measure: stem darkening at
- * smaller sizes where shades of gray dominate. By emboldening a glyph
- * slightly in relation to its pixel size, individual pixels get higher
- * coverage of filled-in outlines and are therefore `blacker'. This
- * counteracts the `thinning out' of glyphs, making text remain readable
- * at smaller sizes. All glyphs that pass through the auto-hinter will
- * be emboldened unless this property is set to TRUE.
- *
- * See the description of the CFF driver for algorithmic details. Total
- * consistency with the CFF driver is currently not achieved because the
- * emboldening method differs and glyphs must be scaled down on the
- * Y-axis to keep outline points inside their precomputed blue zones.
- * The smaller the size (especially 9ppem and down), the higher the loss
- * of emboldening versus the CFF driver.
- *
- * This property can be set via the `FREETYPE_PROPERTIES' environment
- * variable similar to the CFF driver. It can also be set per face
- * using @FT_Face_Properties with @FT_PARAM_TAG_STEM_DARKENING.

- * The CFF driver
- *
- * @abstract:
- * Controlling the CFF driver module.
- *
- * @description:
- * While FreeType's CFF driver doesn't expose API functions by itself,
- * it is possible to control its behaviour with @FT_Property_Set and
- * @FT_Property_Get. The list below gives the available properties
- * together with the necessary macros and structures.
- *
- * The CFF driver's module name is `cff'.
- *
- * *Hinting* *and* *antialiasing* *principles* *of* *the* *new* *engine*
- *
- * The rasterizer is positioning horizontal features (e.g., ascender
- * height & x-height, or crossbars) on the pixel grid and minimizing the
- * amount of antialiasing applied to them, while placing vertical
- * features (vertical stems) on the pixel grid without hinting, thus
- * representing the stem position and weight accurately. Sometimes the
- * vertical stems may be only partially black. In this context,
- * `antialiasing' means that stems are not positioned exactly on pixel
- * borders, causing a fuzzy appearance.
- *
- * There are two principles behind this approach.
- *
- * 1) No hinting in the horizontal direction: Unlike `superhinted'
- * TrueType, which changes glyph widths to accommodate regular
- * inter-glyph spacing, Adobe's approach is `faithful to the design' in
- * representing both the glyph width and the inter-glyph spacing
- * designed for the font. This makes the screen display as close as it
- * can be to the result one would get with infinite resolution, while
- * preserving what is considered the key characteristics of each glyph.
- * Note that the distances between unhinted and grid-fitted positions at
- * small sizes are comparable to kerning values and thus would be
- * noticeable (and distracting) while reading if hinting were applied.
- *
- * One of the reasons to not hint horizontally is antialiasing for LCD
- * screens: The pixel geometry of modern displays supplies three
- * vertical sub-pixels as the eye moves horizontally across each visible
- * pixel. On devices where we can be certain this characteristic is
- * present a rasterizer can take advantage of the sub-pixels to add
- * increments of weight. In Western writing systems this turns out to
- * be the more critical direction anyway; the weights and spacing of
- * vertical stems (see above) are central to Armenian, Cyrillic, Greek,
- * and Latin type designs. Even when the rasterizer uses greyscale
- * antialiasing instead of color (a necessary compromise when one
- * doesn't know the screen characteristics), the unhinted vertical
- * features preserve the design's weight and spacing much better than
- * aliased type would.
- *
- * 2) Alignment in the vertical direction: Weights and spacing along the
- * y~axis are less critical; what is much more important is the visual
- * alignment of related features (like cap-height and x-height). The
- * sense of alignment for these is enhanced by the sharpness of grid-fit
- * edges, while the cruder vertical resolution (full pixels instead of
- * 1/3 pixels) is less of a problem.
- *
- * On the technical side, horizontal alignment zones for ascender,
- * x-height, and other important height values (traditionally called
- * `blue zones') as defined in the font are positioned independently,
- * each being rounded to the nearest pixel edge, taking care of
- * overshoot suppression at small sizes, stem darkening, and scaling.
- *
- * Hstems (this is, hint values defined in the font to help align
- * horizontal features) that fall within a blue zone are said to be
- * `captured' and are aligned to that zone. Uncaptured stems are moved
- * in one of four ways, top edge up or down, bottom edge up or down.
- * Unless there are conflicting hstems, the smallest movement is taken
- * to minimize distortion.

+ * The TrueType driver
+ *
+ * @abstract:
+ * Controlling the TrueType driver module.
+ *
+ * @description:
+ * While FreeType's TrueType driver doesn't expose API functions by
+ * itself, it is possible to control its behaviour with @FT_Property_Set
+ * and @FT_Property_Get. The following lists the available properties
+ * together with the necessary macros and structures.
+ *
+ * The TrueType driver's module name is `truetype'.
+ *
+ * A single property @interpreter-version is available, as documented in
+ * the @properties section.
+ *
+ * We start with a list of definitions, kindly provided by Greg
+ * Hitchcock.
+ *
+ * _Bi-Level_ _Rendering_
+ *
+ * Monochromatic rendering, exclusively used in the early days of
+ * TrueType by both Apple and Microsoft. Microsoft's GDI interface
+ * supported hinting of the right-side bearing point, such that the
+ * advance width could be non-linear. Most often this was done to
+ * achieve some level of glyph symmetry. To enable reasonable
+ * performance (e.g., not having to run hinting on all glyphs just to
+ * get the widths) there was a bit in the head table indicating if the
+ * side bearing was hinted, and additional tables, `hdmx' and `LTSH', to
+ * cache hinting widths across multiple sizes and device aspect ratios.
+ *
+ * _Font_ _Smoothing_
+ *
+ * Microsoft's GDI implementation of anti-aliasing. Not traditional
+ * anti-aliasing as the outlines were hinted before the sampling. The
+ * widths matched the bi-level rendering.
+ *
+ * _ClearType_ _Rendering_
+ *
+ * Technique that uses physical subpixels to improve rendering on LCD
+ * (and other) displays. Because of the higher resolution, many methods
+ * of improving symmetry in glyphs through hinting the right-side
+ * bearing were no longer necessary. This lead to what GDI calls
+ * `natural widths' ClearType, see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec21. Since hinting
+ * has extra resolution, most non-linearity went away, but it is still
+ * possible for hints to change the advance widths in this mode.
+ *
+ * _ClearType_ _Compatible_ _Widths_
+ *
+ * One of the earliest challenges with ClearType was allowing the
+ * implementation in GDI to be selected without requiring all UI and
+ * documents to reflow. To address this, a compatible method of
+ * rendering ClearType was added where the font hints are executed once
+ * to determine the width in bi-level rendering, and then re-run in
+ * ClearType, with the difference in widths being absorbed in the font
+ * hints for ClearType (mostly in the white space of hints); see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec20. Somewhat by
+ * definition, compatible width ClearType allows for non-linear widths,
+ * but only when the bi-level version has non-linear widths.
+ *
+ * _ClearType_ _Subpixel_ _Positioning_
+ *
+ * One of the nice benefits of ClearType is the ability to more crisply
+ * display fractional widths; unfortunately, the GDI model of integer
+ * bitmaps did not support this. However, the WPF and Direct Write
+ * frameworks do support fractional widths. DWrite calls this `natural
+ * mode', not to be confused with GDI's `natural widths'. Subpixel
+ * positioning, in the current implementation of Direct Write,
+ * unfortunately does not support hinted advance widths, see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec22. Note that the
+ * TrueType interpreter fully allows the advance width to be adjusted in
+ * this mode, just the DWrite client will ignore those changes.
+ *
+ * _ClearType_ _Backward_ _Compatibility_
+ *
+ * This is a set of exceptions made in the TrueType interpreter to
+ * minimize hinting techniques that were problematic with the extra
+ * resolution of ClearType; see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec1 and
+ * https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
+ * This technique is not to be confused with ClearType compatible
+ * widths. ClearType backward compatibility has no direct impact on
+ * changing advance widths, but there might be an indirect impact on
+ * disabling some deltas. This could be worked around in backward
+ * compatibility mode.
+ *
+ * _Native_ _ClearType_ _Mode_
+ *
+ * (Not to be confused with `natural widths'.) This mode removes all
+ * the exceptions in the TrueType interpreter when running with
+ * ClearType. Any issues on widths would still apply, though.

+ *
+ * Stem darkening emboldens glyphs at smaller sizes to make them more
+ * readable on common low-DPI screens when using linear alpha blending
+ * and gamma correction, see @FT_Render_Glyph. When not using linear
+ * alpha blending and gamma correction, glyphs will appear heavy and
+ * fuzzy!
+ *
+ * Gamma correction essentially lightens fonts since shades of grey are
+ * shifted to higher pixel values (=~higher brightness) to match the
+ * original intention to the reality of our screens. The side-effect is
+ * that glyphs `thin out'. Mac OS~X and Adobe's proprietary font
+ * rendering library implement a counter-measure: stem darkening at
+ * smaller sizes where shades of gray dominate. By emboldening a glyph
+ * slightly in relation to its pixel size, individual pixels get higher

+ * counteracts the `thinning out' of glyphs, making text remain readable
+ * at smaller sizes.

+ * By default, the Adobe engines for CFF, Type~1, and CID fonts darken

+ * thus switched off by default (this is, `no-stem-darkening' is set to
+ * TRUE by default). Total consistency with the CFF driver is not
+ * achieved right now because the emboldening method differs and glyphs
+ * must be scaled down on the Y-axis to keep outline points inside their
+ * precomputed blue zones. The smaller the size (especially 9ppem and

+ * It is used in FreeType to select the `minimal' subpixel hinting

+ *
+ * @note:
+ * This property controls the behaviour of the bytecode interpreter
+ * and thus how outlines get hinted. It does *not* control how glyph

+ *
+ * If FreeType has not been compiled with the configuration option
+ * TT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 or~40 causes
+ * an `FT_Err_Unimplemented_Feature' error.
+ *
+ * Depending on the graphics framework, Microsoft uses different
+ * bytecode and rendering engines. As a consequence, the version
+ * numbers returned by a call to the `GETINFO' bytecode instruction are
+ * more convoluted than desired.
+ *
+ * Here are two tables that try to shed some light on the possible
+ * values for the MS rasterizer engine, together with the additional
+ * features introduced by it.
+ *
+ * {
+ * GETINFO framework version feature
+ * -------------------------------------------------------------------
+ * 3 GDI (Win 3.1), v1.0 16-bit, first version
+ * TrueImage
+ * 33 GDI (Win NT 3.1), v1.5 32-bit
+ * HP Laserjet

+ * bug fixes
+ * 40 GDI+ (after Win 7), v2.1 Y-direction ClearType flag
+ * DWrite (Win 8) in GETINFO opcode,
+ * Gray ClearType
+ * }
+ *
+ * The `version' field gives a rough orientation only, since some
+ * applications provided certain features much earlier (as an example,
+ * Microsoft Reader used subpixel and Y-direction ClearType already in
+ * Windows 2000). Similarly, updates to a given framework might include
+ * improved hinting support.
+ *
+ * {
+ * version sampling rendering comment
+ * x y x y
+ * --------------------------------------------------------------
+ * v1.0 normal normal B/W B/W bi-level
+ * v1.6 high high gray gray grayscale
+ * v1.8 high normal color-filter B/W (GDI) ClearType
+ * v1.9 high high color-filter gray Color ClearType
+ * v2.1 high normal gray B/W Gray ClearType
+ * v2.1 high high gray gray Gray ClearType
+ * }
+ *
+ * Color and Gray ClearType are the two available variants of
+ * `Y-direction ClearType', meaning grayscale rasterization along the
+ * Y-direction; the name used in the TrueType specification for this
+ * feature is `symmetric smoothing'. `Classic ClearType' is the
+ * original algorithm used before introducing a modified version in
+ * Win~XP. Another name for v1.6's grayscale rendering is `font
+ * smoothing', and `Color ClearType' is sometimes also called `DWrite
+ * ClearType'. To differentiate between today's Color ClearType and the
+ * earlier ClearType variant with B/W rendering along the vertical axis,
+ * the latter is sometimes called `GDI ClearType'.
+ *
+ * `Normal' and `high' sampling describe the (virtual) resolution to
+ * access the rasterized outline after the hinting process. `Normal'
+ * means 1 sample per grid line (i.e., B/W). In the current Microsoft
+ * implementation, `high' means an extra virtual resolution of 16x16 (or
+ * 16x1) grid lines per pixel for bytecode instructions like `MIRP'.
+ * After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid
+ * lines for color filtering if Color ClearType is activated.
+ *
+ * Note that `Gray ClearType' is essentially the same as v1.6's
+ * grayscale rendering. However, the GETINFO instruction handles it
+ * differently: v1.6 returns bit~12 (hinting for grayscale), while v2.1
+ * returns bits~13 (hinting for ClearType), 18 (symmetrical smoothing),
+ * and~19 (Gray ClearType). Also, this mode respects bits 2 and~3 for
+ * the version~1 gasp table exclusively (like Color ClearType), while
+ * v1.6 only respects the values of version~0 (bits 0 and~1).
+ *
+ * Keep in mind that the features of the above interpreter versions
+ * might not map exactly to FreeType features or behavior because it is
+ * a fundamentally different library with different internals.

+ * The warping code can also change advance widths. Have a look at the
+ * `lsb_delta' and `rsb_delta' fields in the @FT_GlyphSlotRec structure
+ * for details on improving inter-glyph distances while rendering.
+ *

- * @section:
- * tt_driver
- *
- * @title:
- * The TrueType driver
- *
- * @abstract:
- * Controlling the TrueType driver module.
- *
- * @description:
- * While FreeType's TrueType driver doesn't expose API functions by
- * itself, it is possible to control its behaviour with @FT_Property_Set
- * and @FT_Property_Get. The following lists the available properties
- * together with the necessary macros and structures.
- *
- * The TrueType driver's module name is `truetype'.
- *
- * We start with a list of definitions, kindly provided by Greg
- * Hitchcock.
- *
- * _Bi-Level_ _Rendering_
- *
- * Monochromatic rendering, exclusively used in the early days of
- * TrueType by both Apple and Microsoft. Microsoft's GDI interface
- * supported hinting of the right-side bearing point, such that the
- * advance width could be non-linear. Most often this was done to
- * achieve some level of glyph symmetry. To enable reasonable
- * performance (e.g., not having to run hinting on all glyphs just to
- * get the widths) there was a bit in the head table indicating if the
- * side bearing was hinted, and additional tables, `hdmx' and `LTSH', to
- * cache hinting widths across multiple sizes and device aspect ratios.
- *
- * _Font_ _Smoothing_
- *
- * Microsoft's GDI implementation of anti-aliasing. Not traditional
- * anti-aliasing as the outlines were hinted before the sampling. The
- * widths matched the bi-level rendering.
- *
- * _ClearType_ _Rendering_
- *
- * Technique that uses physical subpixels to improve rendering on LCD
- * (and other) displays. Because of the higher resolution, many methods
- * of improving symmetry in glyphs through hinting the right-side
- * bearing were no longer necessary. This lead to what GDI calls
- * `natural widths' ClearType, see
- * http://www.beatstamm.com/typography/RTRCh4.htm#Sec21. Since hinting
- * has extra resolution, most non-linearity went away, but it is still
- * possible for hints to change the advance widths in this mode.
- *
- * _ClearType_ _Compatible_ _Widths_
- *
- * One of the earliest challenges with ClearType was allowing the
- * implementation in GDI to be selected without requiring all UI and
- * documents to reflow. To address this, a compatible method of
- * rendering ClearType was added where the font hints are executed once
- * to determine the width in bi-level rendering, and then re-run in
- * ClearType, with the difference in widths being absorbed in the font
- * hints for ClearType (mostly in the white space of hints); see
- * http://www.beatstamm.com/typography/RTRCh4.htm#Sec20. Somewhat by
- * definition, compatible width ClearType allows for non-linear widths,
- * but only when the bi-level version has non-linear widths.
- *
- * _ClearType_ _Subpixel_ _Positioning_
- *
- * One of the nice benefits of ClearType is the ability to more crisply
- * display fractional widths; unfortunately, the GDI model of integer
- * bitmaps did not support this. However, the WPF and Direct Write
- * frameworks do support fractional widths. DWrite calls this `natural
- * mode', not to be confused with GDI's `natural widths'. Subpixel
- * positioning, in the current implementation of Direct Write,
- * unfortunately does not support hinted advance widths, see
- * http://www.beatstamm.com/typography/RTRCh4.htm#Sec22. Note that the
- * TrueType interpreter fully allows the advance width to be adjusted in
- * this mode, just the DWrite client will ignore those changes.
- *
- * _ClearType_ _Backward_ _Compatibility_
- *
- * This is a set of exceptions made in the TrueType interpreter to
- * minimize hinting techniques that were problematic with the extra
- * resolution of ClearType; see
- * http://www.beatstamm.com/typography/RTRCh4.htm#Sec1 and
- * http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
- * This technique is not to be confused with ClearType compatible
- * widths. ClearType backward compatibility has no direct impact on
- * changing advance widths, but there might be an indirect impact on
- * disabling some deltas. This could be worked around in backward
- * compatibility mode.
- *
- * _Native_ _ClearType_ _Mode_
- *
- * (Not to be confused with `natural widths'.) This mode removes all
- * the exceptions in the TrueType interpreter when running with
- * ClearType. Any issues on widths would still apply, though.
- *

- *
- * @property:
- * interpreter-version
- *
- * @description:
- * Currently, three versions are available, two representing the
- * bytecode interpreter with subpixel hinting support (old `Infinality'
- * code and new stripped-down and higher performance `minimal' code) and
- * one without, respectively. The default is subpixel support if
- * TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support
- * otherwise (since it isn't available then).
- *
- * If subpixel hinting is on, many TrueType bytecode instructions behave
- * differently compared to B/W or grayscale rendering (except if `native
- * ClearType' is selected by the font). Microsoft's main idea is to
- * render at a much increased horizontal resolution, then sampling down
- * the created output to subpixel precision. However, many older fonts
- * are not suited to this and must be specially taken care of by
- * applying (hardcoded) tweaks in Microsoft's interpreter.
- *
- * Details on subpixel hinting and some of the necessary tweaks can be
- * found in Greg Hitchcock's whitepaper at
- * `http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'.
- * Note that FreeType currently doesn't really `subpixel hint' (6x1, 6x2,
- * or 6x5 supersampling) like discussed in the paper. Depending on the
- * chosen interpreter, it simply ignores instructions on vertical stems
- * to arrive at very similar results.
- *
- * The following example code demonstrates how to deactivate subpixel
- * hinting (omitting the error handling).
- *
- * {
- * FT_Library library;
- * FT_Face face;
- * FT_UInt interpreter_version = TT_INTERPRETER_VERSION_35;
- *
- *
- * FT_Init_FreeType( &library );
- *
- * FT_Property_Set( library, "truetype",
- * "interpreter-version",
- * &interpreter_version );
- * }
- *
- * @note:
- * This property can be used with @FT_Property_Get also.
- *
- * This property can be set via the `FREETYPE_PROPERTIES' environment
- * variable (using values `35', `38', or `40').

- /**************************************************************************
- *
- * @enum:
- * TT_INTERPRETER_VERSION_XXX
- *
- * @description:
- * A list of constants used for the @interpreter-version property to
- * select the hinting engine for Truetype fonts.
- *
- * The numeric value in the constant names represents the version
- * number as returned by the `GETINFO' bytecode instruction.
- *
- * @values:
- * TT_INTERPRETER_VERSION_35 ::
- * Version~35 corresponds to MS rasterizer v.1.7 as used e.g. in
- * Windows~98; only grayscale and B/W rasterizing is supported.
- *
- * TT_INTERPRETER_VERSION_38 ::
- * Version~38 corresponds to MS rasterizer v.1.9; it is roughly
- * equivalent to the hinting provided by DirectWrite ClearType (as can
- * be found, for example, in the Internet Explorer~9 running on
- * Windows~7). It is used in FreeType to select the `Infinality'
- * subpixel hinting code. The code may be removed in a future
- * version.
- *
- * TT_INTERPRETER_VERSION_40 ::
- * Version~40 corresponds to MS rasterizer v.2.1; it is roughly
- * equivalent to the hinting provided by DirectWrite ClearType (as can
- * be found, for example, in Microsoft's Edge Browser on Windows~10).
- * It is used in FreeType to select the `minimal' subpixel hinting
- * code, a stripped-down and higher performance version of the
- * `Infinality' code.
- *
- * @note:
- * This property controls the behaviour of the bytecode interpreter
- * and thus how outlines get hinted. It does *not* control how glyph
- * get rasterized! In particular, it does not control subpixel color
- * filtering.
- *
- * If FreeType has not been compiled with the configuration option
- * TT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 or~40 causes
- * an `FT_Err_Unimplemented_Feature' error.
- *
- * Depending on the graphics framework, Microsoft uses different
- * bytecode and rendering engines. As a consequence, the version
- * numbers returned by a call to the `GETINFO' bytecode instruction are
- * more convoluted than desired.
- *
- * Here are two tables that try to shed some light on the possible
- * values for the MS rasterizer engine, together with the additional
- * features introduced by it.
- *
- * {
- * GETINFO framework version feature
- * -------------------------------------------------------------------
- * 3 GDI (Win 3.1), v1.0 16-bit, first version
- * TrueImage
- * 33 GDI (Win NT 3.1), v1.5 32-bit
- * HP Laserjet
- * 34 GDI (Win 95) v1.6 font smoothing,
- * new SCANTYPE opcode
- * 35 GDI (Win 98/2000) v1.7 (UN)SCALED_COMPONENT_OFFSET
- * bits in composite glyphs
- * 36 MGDI (Win CE 2) v1.6+ classic ClearType
- * 37 GDI (XP and later), v1.8 ClearType
- * GDI+ old (before Vista)
- * 38 GDI+ old (Vista, Win 7), v1.9 subpixel ClearType,
- * WPF Y-direction ClearType,
- * additional error checking
- * 39 DWrite (before Win 8) v2.0 subpixel ClearType flags
- * in GETINFO opcode,
- * bug fixes
- * 40 GDI+ (after Win 7), v2.1 Y-direction ClearType flag
- * DWrite (Win 8) in GETINFO opcode,
- * Gray ClearType
- * }
- *
- * The `version' field gives a rough orientation only, since some
- * applications provided certain features much earlier (as an example,
- * Microsoft Reader used subpixel and Y-direction ClearType already in
- * Windows 2000). Similarly, updates to a given framework might include
- * improved hinting support.
- *
- * {
- * version sampling rendering comment
- * x y x y
- * --------------------------------------------------------------
- * v1.0 normal normal B/W B/W bi-level
- * v1.6 high high gray gray grayscale
- * v1.8 high normal color-filter B/W (GDI) ClearType
- * v1.9 high high color-filter gray Color ClearType
- * v2.1 high normal gray B/W Gray ClearType
- * v2.1 high high gray gray Gray ClearType
- * }
- *
- * Color and Gray ClearType are the two available variants of
- * `Y-direction ClearType', meaning grayscale rasterization along the
- * Y-direction; the name used in the TrueType specification for this
- * feature is `symmetric smoothing'. `Classic ClearType' is the
- * original algorithm used before introducing a modified version in
- * Win~XP. Another name for v1.6's grayscale rendering is `font
- * smoothing', and `Color ClearType' is sometimes also called `DWrite
- * ClearType'. To differentiate between today's Color ClearType and the
- * earlier ClearType variant with B/W rendering along the vertical axis,
- * the latter is sometimes called `GDI ClearType'.
- *
- * `Normal' and `high' sampling describe the (virtual) resolution to
- * access the rasterized outline after the hinting process. `Normal'
- * means 1 sample per grid line (i.e., B/W). In the current Microsoft
- * implementation, `high' means an extra virtual resolution of 16x16 (or
- * 16x1) grid lines per pixel for bytecode instructions like `MIRP'.
- * After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid
- * lines for color filtering if Color ClearType is activated.
- *
- * Note that `Gray ClearType' is essentially the same as v1.6's
- * grayscale rendering. However, the GETINFO instruction handles it
- * differently: v1.6 returns bit~12 (hinting for grayscale), while v2.1
- * returns bits~13 (hinting for ClearType), 18 (symmetrical smoothing),
- * and~19 (Gray ClearType). Also, this mode respects bits 2 and~3 for
- * the version~1 gasp table exclusively (like Color ClearType), while
- * v1.6 only respects the values of version~0 (bits 0 and~1).
- *
- * Keep in mind that the features of the above interpreter versions
- * might not map exactly to FreeType features or behavior because it is
- * a fundamentally different library with different internals.

+used with libFuzzer (https://llvm.org/docs/LibFuzzer.html) or
potentially any other similar fuzzer.
Usage:
-fsanitize=address,signed-integer-overflow,shift
You also need the header files from the `libarchive' library
- (http://www.libarchive.org/) for handling tar files (see file
+ (https://www.libarchive.org/) for handling tar files (see file
`ftmutator.cc' below for more).
2. Link with `libFuzzer' (it contains `main') and `libarchive'.
The exact flags and commands may vary.

- * Modern TrueType fonts are usually rendered through Microsoft's
- * collection of rendering techniques called ClearType (e.g., subpixel
- * rendering and subpixel hinting). When ClearType was introduced, most
- * fonts were not ready. Microsoft decided to implement a backward
- * compatibility mode that employed several simple to complicated
- * assumptions and tricks that modified the interpretation of the
- * bytecode contained in these fonts to make them look ClearType-y
- * somehow. Most (web)fonts that were released since then have come to
- * rely on these hacks to render correctly, even some of Microsoft's
- * flagship ClearType fonts (Calibri, Cambria, Segoe UI).
+ * FreeType supports ClearType-like hinting of TrueType fonts through
+ * the version 40 interpreter. This is achieved through several hacks
+ * in the base (v35) interpreter, as detailed below.
*
- * The minimal subpixel hinting code (interpreter version 40) employs a
- * small list of font-agnostic hacks to bludgeon non-native-ClearType
- * fonts (except tricky ones[1]) into submission. It will not try to
- * toggle hacks for specific fonts for performance and complexity
- * reasons. The focus is on modern (web)fonts rather than legacy fonts
- * that were made for black-and-white rendering.
+ * ClearType is an umbrella term for several rendering techniques
+ * employed by Microsoft's various GUI and rendering toolkit
+ * implementations, most importantly: subpixel rendering for using the
+ * RGB subpixels of LCDs to approximately triple the perceived
+ * resolution on the x-axis and subpixel hinting for positioning stems
+ * on subpixel borders. TrueType programming is explicit, i.e., fonts
+ * must be programmed to take advantage of ClearType's possibilities.
+ *
+ * When ClearType was introduced, it seemed unlikely that all fonts
+ * would be reprogrammed, so Microsoft decided to implement a backward
+ * compatibility mode. It employs several simple to complicated
+ * assumptions and tricks, many of them font-dependent, that modify the
+ * interpretation of the bytecode contained in these fonts to retrofit
+ * them into a ClearType-y look. The quality of the results varies.
+ * Most (web)fonts that were released since then have come to rely on
+ * these hacks to render correctly, even some of Microsoft's flagship
+ * fonts (e.g., Calibri, Cambria, Segoe UI).
+ *
+ * FreeType's minimal subpixel hinting code (interpreter version 40)
+ * employs a small list of font-agnostic hacks loosely based on the
+ * public information available on Microsoft's compatibility mode[2].
+ * The focus is on modern (web)fonts rather than legacy fonts that were
+ * made for monochrome rendering. It will not match ClearType rendering
+ * exactly. Unlike the `Infinality' code (interpreter version 38) that
+ * came before, it will not try to toggle hacks for specific fonts for
+ * performance and complexity reasons. It will fall back to version 35
+ * behavior for tricky fonts[1] or when monochrome rendering is
+ * requested.
