- [mac] Fix ftexport.sym target in Jamfile.
-
- * Jamfile: Update the directories of the header files scanned for
- ftexport.sym. They were incorrect since the migration of the
- header files, on 2015-06-22. Either inexisting include/cache
- (removed on 2006-03-20) is not needed to be listed explicitly.
- Now ftmac.h is scanned only in the case of Mac OS & Mac OS X.

-
- [smooth] Sub-banding protocol revision.
-
- Rasterization sub-banding is utilized at large sizes while using a
- rather small fixed memory pool. Indeed it is possible to make an
- educated guess how much memory is necessary at a given size for a
- given glyph. It turns out that, for a large majority of European
- glyphs, you should store about 8 times more boundary pixels than
- their height. Or, vice versa, if your memory pool can hold 800
- pixels the band height should be 100 and you should sub-band
- anything larger than that. Should you still run out of memory,
- FreeType bisects the band but you have wasted some time. This is
- what has been implemented in FreeType since the beginning.
-
- It was overlooked, however, that the top band could grow to twice
- the default band size leading to unnecessary memory overflows there.
- This commit fixes that. Now the bands are distributed more evenly
- and cannot exceed the default size.
-
- Now the magic number 8 is really suitable for rather simple European
- scripts. For complex Chinese logograms the magic number should be
- 13 but that is subject for another day.
-
- * src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding
- protocol.

-2016-05-28 Werner Lemberg <wl@gnu.org>
-
- * src/autofit/afranges.c: Remove `UL' postfix from hex numbers.
-
- Suggested by Alexei. `UL' is only needed for 16bit compilers, but
- it seems noone is using this anymore (and we no longer test whether
- FreeType compiles in such an environment). Otherwise, it is easy to
- add the postfix to the `AF_UNICODE_RANGE' macro.

-
- [smooth] Shrink bisection stack.
-
- The convergence of Bézier flatteners is fast with the deviation
- from straight line being assymptotically cut 4-fold on each bisection.
- This justifies smaller bisection stack size.
-
- * src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'.
- (gray_render_conic): Create and use conic `bez_stack'. Move back the
- band analysis from...

-
-2016-05-23 Werner Lemberg <wl@gnu.org>
-
- * builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'.
-
- This was commented about 10 years ago – I think the reason then to
- disable libtool's `-export-symbols' option was to give some badly
- programmed applications access to internal FreeType functions.
-
- I believe that we should no longer take care of such programs; the
- number of symbols exported should be rather restricted as much as
- possible.
-

- [autofit] Add support for Georgian scripts.
+ [autofit] Add support for Osmanya script.
- Georgian is problematic, since `uppercase' forms of Mkhedruli
- (called Mtavruli) are not yet defined in Unicode, which means that
- proper blue zones can't be defined. However, there is already a
- proposal submitted to Unicode; see
+ * src/autofit/afblue.dat: Add blue zone data for Osmanya.
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
- http://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf
+ * src/autofit/afscript.h: Add Osmanya standard character.
- Additionally, due to historical reasons, Unicode treats Khutsuri as
- the same script as Mkhedruli, and so does OpenType. However, since
- the two scripts have completely different shapes it can happen that
- blue zones differ considerably. The tag `geok' used here (derived
- from ISO 15924) to differentiate the two scripts is not an OpenType
- tag in use. If we now have a font that contains both glyphs for
- Mkhedruli and Khutsuri, and it uses OpenType features for both also,
- HarfBuzz unavoidably treats all glyphs as `geor'. As a consequence,
- blue zones for `geok' are not used for glyphs involved in the
- OpenType features.
+ * src/autofit/afranges.c, src/autofit/afstyles.h: Add Osmanya data.
- An issue not yet resolved is which OpenType feature should be used
- to access Mtavruli glyph shapes; right now, FreeType doesn't set up
- support for them, but it is easy to add them later on as soon as
- more information is available.

-
- [autofit] Fix handling of default script.
-
- Patch taken from ttfautohint, commit
- 071ae2c00e0d67f9d19418f4fade1c23d27dc185.
-
- There were two bugs.
-
- - We now use non-standard script tags like `khms' for special
- purposes. However, HarfBuzz maps such tags to `DFLT', and
- without this commit the associated lookups were incorrectly
- assigned to the non-standard tags.
-
- - Let's assume we have a Bengali font, and the font's `DFLT'
- script tag handles the necessary lookups for Bengali, too.
- Without this commit, the `DFLT' lookups were assigned to
- ttfautohint's default script (usually `latn') before the
- standard lookups for Bengali were handled.
-
- We now have the following order while searching for covered
- glyph indices.
-
- special features of scripts (e.g. `sups' for Cyrillic)
- Unicode mappings of scripts
- remaining features of scripts (especially important for Indic
- scripts)
- default features of default script
-
- * src/autofit/afshaper.c, src/autofit/afshaper.h
- (af_shaper_get_coverage): Add boolean parameter to indicate default
- script.

+ Add new `slight' auto-hinting mode.
- [autofit] Add support for Khmer script.
+ This mode uses fractional advance widths and doesn't scale glyphs
+ horizontally, only applying vertical scaling and hinting.
- We split Khmer into two auto-hinter scripts: `Khmer' (`khmr') and
- `Khmer symbols' (`khms', U+19E0-U+19FF).
+ 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.
- * src/autofit/afblue.dat: Add blue zone data for Khmer.
+ * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro.

+2017-04-22 Werner Lemberg <wl@gnu.org>
- The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
- and `af_shaper_buf_destroy'. The buffer receives a UTF8 encoded
- string with function `af_shaper_get_cluster', and the resulting

- [type1] Protect against invalid number of subroutines (#46150).
+ 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/type1/t1load.c (parse_subrs): Check number of
- `Subrs' dictionary entries against size of data stream.
+ 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.

- reducing the number of divisions to just two per line segment, which
- is a bare minimum to calculate cell coverage in a smooth rasterizer.

+2016-08-30 Alexei Podtelezhnikov <apodtele@gmail.com>
- If a glyph has only one very narrow feature, the bbox can end up
- with either the width or height of the bbox being 0, in which case
- no raster memory is allocated and no attempt is made to render the
- glyph. This is less than ideal when the drop-out compensation in
- the rendering code would actually result in the glyph being
- rendered.
+ [smooth] Streamline pixmap drawing a bit more.
- This problem can be observed with the `I' glyph (gid 47) in the
- Autodesk RomanS TrueType font.
+ Zero coverage is unlikely (1 out of 256) to warrant checking. This
+ gives 0.5% speed improvement in rendering simple glyphs.

+
+ [smooth] Sub-banding protocol revision.
+
+ Rasterization sub-banding is utilized at large sizes while using a
+ rather small fixed memory pool. Indeed it is possible to make an
+ educated guess how much memory is necessary at a given size for a
+ given glyph. It turns out that, for a large majority of European
+ glyphs, you should store about 8 times more boundary pixels than
+ their height. Or, vice versa, if your memory pool can hold 800
+ pixels the band height should be 100 and you should sub-band
+ anything larger than that. Should you still run out of memory,
+ FreeType bisects the band but you have wasted some time. This is
+ what has been implemented in FreeType since the beginning.
+
+ It was overlooked, however, that the top band could grow to twice
+ the default band size leading to unnecessary memory overflows there.
+ This commit fixes that. Now the bands are distributed more evenly
+ and cannot exceed the default size.
+
+ Now the magic number 8 is really suitable for rather simple European
+ scripts. For complex Chinese logograms the magic number should be
+ 13 but that is subject for another day.

+
+ [autofit] Add support for Georgian scripts.
+
+ Georgian is problematic, since `uppercase' forms of Mkhedruli
+ (called Mtavruli) are not yet defined in Unicode, which means that
+ proper blue zones can't be defined. However, there is already a
+ proposal submitted to Unicode; see
+
+ http://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf
+
+ Additionally, due to historical reasons, Unicode treats Khutsuri as
+ the same script as Mkhedruli, and so does OpenType. However, since
+ the two scripts have completely different shapes it can happen that
+ blue zones differ considerably. The tag `geok' used here (derived
+ from ISO 15924) to differentiate the two scripts is not an OpenType
+ tag in use. If we now have a font that contains both glyphs for
+ Mkhedruli and Khutsuri, and it uses OpenType features for both also,
+ HarfBuzz unavoidably treats all glyphs as `geor'. As a consequence,
+ blue zones for `geok' are not used for glyphs involved in the
+ OpenType features.
+
+ An issue not yet resolved is which OpenType feature should be used
+ to access Mtavruli glyph shapes; right now, FreeType doesn't set up
+ support for them, but it is easy to add them later on as soon as
+ more information is available.

+
+ [autofit] Fix handling of default script.
+
+ Patch taken from ttfautohint, commit
+ 071ae2c00e0d67f9d19418f4fade1c23d27dc185.
+
+ There were two bugs.
+
+ - We now use non-standard script tags like `khms' for special
+ purposes. However, HarfBuzz maps such tags to `DFLT', and
+ without this commit the associated lookups were incorrectly
+ assigned to the non-standard tags.
+
+ - Let's assume we have a Bengali font, and the font's `DFLT'
+ script tag handles the necessary lookups for Bengali, too.
+ Without this commit, the `DFLT' lookups were assigned to
+ ttfautohint's default script (usually `latn') before the
+ standard lookups for Bengali were handled.
+
+ We now have the following order while searching for covered
+ glyph indices.
+
+ special features of scripts (e.g. `sups' for Cyrillic)
+ Unicode mappings of scripts
+ remaining features of scripts (especially important for Indic
+ scripts)
+ default features of default script
+
+ * src/autofit/afshaper.c, src/autofit/afshaper.h

+
+2015-12-09 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Introduce subscript top blue zones.
+
+ This feature is mainly for Khmer: The idea is to avoid a clash
+ between the top of subscript glyphs and the bottom of normal
+ baseline glyphs.
+
+ This only works for character clusters mapped to multiple glyphs.
+
+ * src/autofit/afblue.dat: Add subscript top blue zone for Khmer.
+

+
+2015-12-06 Werner Lemberg <wl@gnu.org>

+
+2015-12-06 Werner Lemberg <wl@gnu.org>

+
+ [autofit] Add support for Khmer script.
+
+ We split Khmer into two auto-hinter scripts: `Khmer' (`khmr') and
+ `Khmer symbols' (`khms', U+19E0-U+19FF).
+
+ * src/autofit/afblue.dat: Add blue zone data for Khmer.

+
+2015-12-06 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Rewrite HarfBuzz interface to support character clusters.
+
+ Scripts like Khmer have blue zones that can't be directly
+ represented by Unicode characters. Instead, it is necessary to let
+ HarfBuzz convert character clusters into proper glyph representation
+ forms, then deriving the blue zone information from the resulting
+ glyphs.
+
+ * src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
+ * src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
+ files, providing a new API to access HarfBuzz.
+
+ The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
+ and `af_shaper_buf_destroy'. The buffer receives a UTF8 encoded
+ string with function `af_shaper_get_cluster', and the resulting
+ glyph data (indices, advance widths, vertical offsets) can be
+ iteratively accessed with function `af_shaper_get_elem'.
+
+ * src/autofit/afcjk.c (af_cjk_metrics_init_widths,
+ af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.

+
+ [smooth] Faster alternative line renderer.
+
+ This implementation renders the entire line segment at once without
+ subdividing it into scanlines. The main speed improvement comes from
+ reducing the number of divisions to just two per line segment, which
+ is a bare minimum to calculate cell coverage in a smooth rasterizer.
+ Notably, the progression from cell to cell does not itself require any
+ divisions at all. The speed improvement is more noticeable at larger

+ [sfnt] Better checks for invalid cmaps (2/2) (#46019).
+
+ While the current code in `FT_Get_Next_Char' correctly rejects

+
+ [sfnt] Improve handling of invalid SFNT table entries (#45987).
+
+ This patch fixes weaknesses in function `tt_face_load_font_dir'.
+
+ - It incorrectly assumed that valid tables are always at the
+ beginning. As a consequence, some valid tables after invalid
+ entries (which are ignored) were never seen.
+
+ - Duplicate table entries (this is, having the same tag) were not
+ rejected.
+
+ - The number of valid tables was sometimes too large, leading to
+ access of invalid tables.
+
+ * src/sfnt/ttload.c (check_table_dir): Add argument to return number
+ of valid tables.
+ Add another tracing message.
+ (tt_face_load_font_dir): Only allocate table array for valid
+ entries as returned by `check_table_dir'.
+ Reject duplicate tables and adjust number of valid tables
+ accordingly.

+
+ [autofit] Redesign code ranges (1/2).
+
+ This patch introduces auxiliary code ranges that identify no-base
+ characters; they refer to glyphs of a script that should be hinted
+ without alignments to blue zones (mostly diacritics).
+
+ It also splits off ranges for fallback scripts that handle subscript
+ and superscript characters not covered by OpenType features. For
+ example, this greatly helps improve the hinting of various phonetic
+ alphabets, which contain a large amount characters that look like
+ superscript glyphs.
+
+ Finally, code ranges are updated to Unicode 8.0, and enclosed
+ characters are removed in general since they normally look better if
+ they stay unhinted.
+
+ * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode
+ 8.0.
+ Split off superscript-like and subscript-like glyphs into...
+
+ (af_latb_uniranges, af_latp_uniranges): ... these two new arrays.
+
+ (af_xxxx_nobase_uniranges): New arrays that hold no-base characters
+ of the corresponding character ranges.

+
+ [type42] Fix glyph access.
+
+ This is a severe bug: We've missed one level of indirection, as

+
+2015-06-03 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix memory leak.
+
+ Problem reported by Grissiom <chaos.proton@gmail.com>; in
+
+ http://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html
+
+ there is an example code to trigger the bug.
+
+ * src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size'
+ data before allocating again. Bug most probably introduced four
+ years ago in version 2.4.3.
+
+2015-06-02 Werner Lemberg <wl@gnu.org>
+
+ [raster] Add more tracing.
+
+ * src/raster/ftraster.c (FT_TRACE7) [_STANDALONE_]: Define.
+ (Vertical_Sweep_Span, Vertical_Sweep_Drop, Horizontal_Sweep_Span,
+ Horizontal_Sweep_Drop, Render_Glyph): Add tracing calls.
+
+2015-06-01 Werner Lemberg <wl@gnu.org>
+
+ [truetype] While tracing opcodes, show code position and stack.
+
+ * src/truetype/ttinterp.c: Change all existing TRACE7 calls to
+ TRACE6.
+ (opcode_name): Add string lengths.
+ (TT_RunIns): Implement display of code position and stack.
+
+2015-05-31 Werner Lemberg <wl@gnu.org>
+
+ [truetype] In GX, make private point numbers work correctly.
+
+ This is completely missing in Apple's documentation: If a `gvar'
+ tuple uses private point numbers (this is, deltas are specified for
+ some points only), the uncovered points must be interpolated for
+ this tuple similar to the IUP bytecode instruction. Examples that
+ need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.
+
+ * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
+ tt_handle_deltas): New functions.
+ (TT_Vary_Get_Glyph_Deltas): Renamed to...
+ (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the
+ points and does no longer return an array of deltas.
+ Add tracing information.
+ Call `tt_handle_deltas' to interpolate missing deltas.
+ Also fix a minor memory leak in case of error.
+
+ * src/truetype/ttgxvar.h: Updated.
+
+ * src/truetype/ttgload.c (TT_Process_Simple_Glyph,
+ load_truetype_glyph): Updated.
+
+2015-05-31 Werner Lemberg <wl@gnu.org>

+ ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend,
+ TT_Set_Var_Design, tt_face_vary_cvt): Do it.
+

+
+2015-05-24 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix commit from 2015-05-22.
+
+ * src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code
+ with `TT_CONFIG_OPTION_SUBPIXEL_HINTING'.

+
+2015-05-23 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix return values of GETINFO bytecode instruction.
+
+ * src/truetype/ttinterp.h (TT_ExecContextRec): New fields
+ `vertical_lcd' and `gray_cleartype'.
+
+ * src/truetype/ttgload.c (tt_loader_init): Initialize new fields.
+ Change `symmetrical smoothing' to TRUE, since FreeType produces
+ exactly this.
+
+ * src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit
+ values for symmetrical smoothing, namely 11/18.
+ Handle bits for vertical LCD subpixels (8/15) and Gray ClearType
+ (12/19).
+
+2015-05-23 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Minor.
+
+ * src/truetype/ttinterp.h (TT_ExecContext):
+ s/subpixel/subpixel_hinting.
+
+ * src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.
+
+2015-05-22 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Support selector index 3 of the INSTCTRL instruction.
+
+ This flag activates `native ClearType hinting', disabling backward
+ compatibility mode as described in Greg Hitchcocks whitepaper. In
+ other words, it enables unrestricted functionality of all TrueType
+ instructions in ClearType.
+
+ * src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
+ unconditionally.
+ (tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of
+ `GS.instruct_control' is active.
+
+ * src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.
+ (Ins_GETINFO): Updated.
+
+ * docs/CHANGES: Document it.
+
+2015-05-20 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Minor.
+
+ * src/truetype/ttinterp.h (SetSuperRound): Fix type of `GridPeriod'
+ argument.
+
+2015-05-17 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix loading of composite glyphs.
+
+ * src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
+ ARGS_ARE_XY_VALUES flag is not set, handle argument values as
+ unsigned. I trust `ttx' (which has exactly such code) that it does
+ the right thing here...
+
+ The reason that noone has ever noticed this bug is probably the fact
+ that point-aligned subglyphs are rare, as are subglyphs with a
+ number of points in the range [128;255], which is quite large (or
+ even in the range [32768;65535], which is extremely unlikely).
+
+2015-05-12 Chris Liddell <chris.liddell@artifex.com>
+
+ [cff] Make the `*curveto' operators more tolerant.
+
+ * src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
+ `vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
+ pulling values off the stack until the stack is exhausted.
+ Implicitly the stack must be a multiple (or for subtly different
+ behaviour) a multiple plus a specific number of extra values deep.
+ If that's not the case, enforce it (as the old code did).
+
+2015-05-12 Chris Liddell <chris.liddell@artifex.com>
+
+ [cff] fix incremental interface with new cff code.
+
+ * src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
+ interface to retrieve glyph data for a SEAC, it be left to the
+ incremental interface callback to apply the encoding to raw
+ character index (as it was in the previous code).
+
+2015-04-29 Alexei Podtelezhnikov <apodtele@gmail.com>
+

+
+2015-04-28 Werner Lemberg <wl@gnu.org>
+
+ [cff] Use `name' table for PS name if we have a SFNT-CFF.
+
+ This follows the OpenType 1.7 specification. See
+
+ http://tug.org/pipermail/tex-live/2015-April/036634.html
+
+ for a discussion.
+
+ * src/cff/cffdrivr.c (cff_get_ps_name): Use the `sfnt' service if we

+
+ [raster] Fix Savannah bug #44022.
+
+ Add fallback for glyphs with degenerate bounding boxes.
+
+ If a glyph has only one very narrow feature, the bbox can end up
+ with either the width or height of the bbox being 0, in which case
+ no raster memory is allocated and no attempt is made to render the
+ glyph. This is less than ideal when the drop-out compensation in
+ the rendering code would actually result in the glyph being
+ rendered.
+
+ This problem can be observed with the `I' glyph (gid 47) in the
+ Autodesk RomanS TrueType font.
+
+ * src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either
+ dimension is zero to explicitly round up/down (instead of simply
+ round).
+
+2015-01-17 Werner Lemberg <wl@gnu.org>
+
+ Add some tools to handle yearly copyright notice updates.

+
+ * src/tools/update-copyright-year: New Perl script.
+ * src/tools/update-copyright: New shell script that calls

+ Avoids multiple mallocs per typical glyphs.

+ cached singleton.
+

+
+ [autofit] Reuse slot glyph loader.
+
+ No need to create a new glyph loader; we can reuse the one from
+ `slot->internal->loader'. It's hard to tell why it was written that
+ way originally, but new code looks sound and correct to me, and
+ avoids lots of allocations.
+
+ * src/autofit/afloader.c (af_loader_init): Change return type to
+ `void'.
+ Don't call `FT_GlyphLoader_New'.
+ (af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.
+ (af_loader_load_g): Update code to use `internal->loader', which
+ doesn't need copying of data.
+
+ * src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member.

+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [autofit] Remove (unused) support for composite glyphs.
+
+ We never have to deal with composite glyphs in the autohinter, as
+ those will be loaded into FORMAT_OUTLINE by the recursed
+ `FT_Load_Glyph' function.
+
+ In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply
+ FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies
+ FT_LOAD_NO_HINTING:
+
+ /* resolve load flags dependencies */
+
+ if ( load_flags & FT_LOAD_NO_RECURSE )
+ load_flags |= FT_LOAD_NO_SCALE |
+ FT_LOAD_IGNORE_TRANSFORM;
+
+ if ( load_flags & FT_LOAD_NO_SCALE )
+ {
+ load_flags |= FT_LOAD_NO_HINTING |
+ FT_LOAD_NO_BITMAP;
+
+ load_flags &= ~FT_LOAD_RENDER;
+ }
+
+ and as such the auto-hinter is never called. Thus, the recursion in
+ `af_loader_load_g' never actually happens. So remove the depth
+ counter as well.
+
+ * src/autofit/afloader.c (af_loader_load_g): Remove `depth'
+ parameter.
+ <FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.
+ (af_loader_load_glyph): Updated.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [raster] Fix uninitialized memory access.
+
+ Apparently `ras.cProfile' might be uninitialized. This will be the
+ case if `ras.top == ras.cProfile->offset', as can be seen in
+ `End_Profile'. The overshoot code introduced in a change `Fix B/W
+ rasterization of subglyphs with different drop-out modes.' (from
+ 2009-06-18) violated this, accessing `ras.cProfile->flags'
+ unconditionally just before calling `End_Profile' (which then
+ detected that `cProfile' is uninitialized and didn't touch it).
+
+ This was harmless, and was not detected by valgrind before because
+ the objects were allocated on the `raster_pool', which was always
+ initialized. With recent change to allocate raster buffers on the
+ stack, valgrind now reported this invalid access.
+
+ * src/raster/ftraster.c (Convert_Glyph): Don't access an
+ uninitialized `cProfile'.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [smooth] Fix uninitialized memory access.
+
+ Looks like `ras.span_y' could always be used without initialization.
+ This was never detected by valgrind before because the library-wide
+ `raster_pool' was used for the worker object and `raster_pool' was
+ originally zero'ed. But subsequent reuses of it were using `span_y'
+ uninitialized. With the recent change to not use `render_pool' and
+ allocate worker and buffer on the stack, valgrind now detects this
+ uninitialized access.
+
+ * src/smooth/ftgrays.c (gray_raster_render): Initialize
+ `ras.span_y'.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [base] Don't initialize unused `driver->glyph_loader'.
+
+ * src/base/ftobjs.c (Destroy_Driver): Don't call

+ (FT_Add_Module): Don't call `FT_GlyphLoader_New'.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [base] Don't allocate `library->raster_pool' anymore.
+
+ It's unused after the following commits:
+
+ [raster] Allocate render pool for mono rasterizer on the stack.
+ [raster] Remove 5-level gray AA mode from monochrome rasterizer.
+
+ The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
+ serve, which is, to adjust the pool size. But the pool is now
+ allocated on the stack on demand.
+
+ * src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [base] Do not reorder library->renderers upon use.
+
+ Instead of keeping `library->renderers' in a MRU order, just leave
+ it as-is. The MRU machinery wasn't thread-safe.
+
+ With this patch, rasterizing glyphs from different faces from
+ different threads doesn't fail choosing rasterizer
+ (FT_Err_Cannot_Render_Glyph).
+
+ Easiest to see that crash was to add a `printf' (or otherwise let
+ thread yield in FT_Throw with debugging enabled).
+
+ * src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c
+ (FT_Outline_Render): Don't call `FT_Set_Renderer'.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [raster] Allocate render pool for mono rasterizer on the stack.
+
+ Instead of using the `render_pool' member of `FT_Library' that is
+ provided down to the rasterizer, completely ignore that and allocate
+ needed objects on the stack instead.
+
+ With this patch, rasterizing glyphs from different faces from
+ different threads doesn't crash in the monochrome rasterizer.
+
+ * src/raster/ftraster.c (black_TRaster): Remove `buffer',
+ `buffer_size', and `worker' members.
+
+ (ft_black_render): Create `buffer' locally.
+ (ft_black_reset): Updated.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [raster] Remove 5-level gray AA mode from monochrome rasterizer.
+
+ It was off by default and couldn't be turned on at runtime. And the
+ smooth rasterizer superseded it over ten years ago. No point in
+ keeping. Comments suggested that it was there for compatibility
+ with FreeType 1.
+
+ 550 lines down.
+
+ * src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING,
+ RASTER_GRAY_LINES): Remove macros and all associated code.
+

+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [smooth] Allocate render pool for smooth rasterizer on the stack.
+
+ Instead of using the `render_pool' member of `FT_Library' that is
+ provided down to the rasterizer, completely ignore that and allocate
+ needed objects on the stack instead.
+
+ With this patch, rasterizing glyphs from different faces from
+ different threads doesn't crash in the smooth rasterizer.

+
+ [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
+
+ Previously the code had stipulation for using a per-TT_Size exec
+ context if `size->debug' was true. But there was no way that
+ `size->debug' could *ever* be true. As such, the code was always
+ using the singleton `TT_ExecContext' that was stored in `TT_Driver'.
+ This was, clearly, not threadsafe.
+
+ With this patch, loading glyphs from different faces from different
+ threads doesn't crash in the bytecode loader code.
+

+CHANGES BETWEEN 2.7.1 and 2.8
+
+ I. IMPORTANT CHANGES
+
+ - Support for OpenType Variation Fonts is now complete. The last
+ missing part was handling the `VVAR' and `MVAR' tables, which is
+ available with this release.
+
+ - A new function `FT_Face_Properties' allows the control of some
+ module and library properties per font. Currently, the
+ following properties can be handled: stem darkening, LCD filter
+ weights, and the random seed for the `random' CFF operator.
+
+ - The PCF change to show more `colourful' family names (introduced
+ in version 2.7.1) was too radical; it can now be configured with
+ PCF_CONFIG_OPTION_LONG_FAMILY_NAMES at compile time. If
+ activated, it can be switched off at run time with the new pcf
+ property `no-long-family-names'. If the `FREETYPE_PROPERTIES'
+ environment variable is available, you can say
+
+ FREETYPE_PROPERTIES=pcf:no-long-family-names=1
+
+ - Support for the following scripts has been added to the
+ auto-hinter.
+
+ Adlam, Avestan, Bamum, Buhid, Carian, Chakma, Coptic, Cypriot,
+ Deseret, Glagolitic, Gothic, Kayah, Lisu, N'Ko, Ol Chiki, Old
+ Turkic, Osage, Osmanya, Saurashtra, Shavian, Sundanese, Tai
+ Viet, Tifinagh, Unified Canadian Syllabics, Vai
+
+
+ II. IMPORTANT BUG FIXES
+
+ - `Light' auto-hinting mode no longer uses TrueType metrics for
+ TrueType fonts. This bug was introduced in version 2.4.6,
+ causing horizontal scaling also. Almost all GNU/Linux
+ distributions (with Fedora as a notable exception) disabled the
+ corresponding patch for good reasons; chances are thus high that
+ you won't notice a difference.
+
+ If optical backward compatibility for legacy applications is
+ necessary, you might enable the AF_CONFIG_OPTION_TT_SIZE_METRICS
+ configuration option. However, it is strongly recommended to
+ avoid that, adjusting font sizes instead.
+
+ - 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).
+
+ - CVE-2017-8105, CVE-2017-8287: Older FreeType versions have
+ out-of-bounds writes caused by heap-based buffer overflows
+ related to Type 1 fonts.
+
+ https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8105
+ https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8287
+
+
+ III. MISCELLANEOUS
+
+ - A new function `FT_Set_Default_Properties' has been added to
+ parse the `FREETYPE_PROPERTIES' environment variable
+ (previously, it was internal only). `FT_Init_FreeType' always
+ call this function, but `FT_New_Library' does not (similar to
+ `FT_Add_Default_Modules').
+
+ - To be in sync with OpenType version 1.7 and newer, macros
+
+ FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY,
+ FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY,
+ TT_NAME_ID_PREFERRED_FAMILY
+ TT_NAME_ID_PREFERRED_SUBFAMILY
+
+ are renamed to
+
+ FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_FAMILY,
+ FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_SUBFAMILY,
+ TT_NAME_ID_TYPOGRAPHIC_FAMILY
+ TT_NAME_ID_TYPOGRAPHIC_SUBFAMILY
+
+ The old macro names are deprecated (but still available).
+
+ - Support for SFNT `name' tables has been improved.
+
+ . Format 1 `name' tables are now supported. Use new function
+ `FT_Get_Sfnt_LangTag' to access associated language tags.
+
+ . Language, encoding, and name IDs have been updated to OpenType
+ version 1.8.1.
+
+ - The new CFF engine now handles the `random' operator. All CFF
+ opcodes are now supported.
+
+ - The CFF module has a new property `random-seed' to control the
+ pseudo-random number generation for the `random' operator.
+
+ - The `freetype-config' script is now a wrapper of `pkg-config' if
+ this program is available in the path.
+
+ - FT_LOAD_TARGET_LCD is now a variant of FT_LOAD_TARGET_LIGHT;
+ this should provide better rendering results.
+
+ - A mode to display light auto-hinting with sub-pixel positioning
+ has been added to `ftdiff'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.7 and 2.7.1
+
+ I. IMPORTANT CHANGES
+
+ - Support for the new CFF2 font format as introduced with OpenType
+ 1.8 has been contributed by Dave Arnolds from Adobe.
+
+ - Preliminary support for variation fonts as specified in OpenType
+ 1.8 (in addition to the already existing support for Adobe's MM
+ and Apple's GX formats). Dave Arnolds contributed handling of
+ advance width change variation; more will come in the next
+ version.
+
+
+ II. IMPORTANT BUG FIXES
+
+ - Handling of raw CID fonts was partially broken (bug introduced
+ in 2.6.4).
+
+ - CVE-2016-10328: Older FreeType versions had an out-of-bounds
+ write caused by a heap-based buffer overflow related to the CFF
+ fonts.
+
+ http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-10328
+
+
+ III. MISCELLANEOUS
+
+ - Some limits for TrueType bytecode execution have been tightened
+ to speed up FreeType's handling of malformed fonts, in
+ particular to quickly abort endless loops.
+
+ - The number of twilight points can no longer be set to an
+ arbitrarily large value.
+
+ - The total number of jump opcode instructions (like JMPR) with
+ negative arguments is dynamically restricted; the same holds
+ for the total number of iterations in LOOPCALL opcodes.
+
+ The dynamic limits are based on the number of points in a glyph
+ and the number of CVT entries. Please report if you encounter a
+ font where the selected values are not adequate.
+
+ - PCF family names are made more `colourful'; they now include the
+ foundry and information whether they contain wide characters.
+ For example, you no longer get `Fixed' but rather `Sony Fixed'
+ or `Misc Fixed Wide'.
+
+ - A new function `FT_Get_Var_Blend_Coordinates' (with its alias
+ name `FT_Get_MM_Blend_Coordinates') to retrieve the normalized
+ blend coordinates of the currently selected variation instance
+ has been added to the Multiple Masters interface.
+
+ - A new function `FT_Get_Var_Design_Coordinates' to retrieve the
+ design coordinates of the currently selected variation instance
+ has been added to the Multiple Masters interface.
+
+ - A new load flag `FT_LOAD_BITMAP_METRICS_ONLY' to retrieve bitmap
+ information without loading the (embedded) bitmap itself.
+
+ - Retrieving advance widths from bitmap strikes (using
+ `FT_Get_Advance' and `FT_Get_Advances') have been sped up.
+
+ - The usual round of fuzzer fixes to better reject malformed
+ fonts.
+
+ - The `ftmulti' demo program can now switch engines with key `H'.
+
+ - The `ftstring' demo program can now show some built-in,
+ non-latin sample strings (to be selected with the TAB key).
+
+ - The `ftview' demo program can now switch between a font's
+ charmaps using the TAB key.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.5 and 2.7
+
+ I. IMPORTANT CHANGES
+
+ - As announced earlier, the 2.7.x series now uses the new subpixel
+ hinting mode as the default, emulating a modern version of
+ ClearType.
+
+ This change inevitably leads to different rendering results, and
+ you might change the `TT_CONFIG_OPTION_SUBPIXEL_HINTING'
+ configuration option to adapt it to your taste (or use the new
+ `FREETYPE_PROPERTIES' environment variable). See the
+ corresponding entry below for version 2.6.4, which gives more
+ information.
+
+ - A new option `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' has been
+ introduced. If set (which is the default), an environment
+ variable `FREETYPE_PROPERTIES' can be used to control driver
+ properties. Example:
+
+ FREETYPE_PROPERTIES=truetype:interpreter-version=35 \
+ cff:no-stem-darkening=1 \
+ autofitter:warping=1
+
+ This allows to select, say, the subpixel hinting mode at runtime
+ for a given application. See file `ftoption.h' for more.
+
+
+ II. IMPORTANT BUG FIXES
+
+ - After loading a named instance of a GX variation font, the
+ `face_index' value in the returned `FT_Face' structure now
+ correctly holds the named instance index in the upper 16bits as
+ documented.
+
+
+ III. MISCELLANEOUS
+
+ - A new macro `FT_IS_NAMED_INSTANCE' to test whether a given face
+ is a named instance.
+
+ - More fixes to GX font handling.
+
+ - Apple's `GETVARIATION' bytecode operator (needed for GX
+ variation font support) has been implemented.
+
+ - Another round of fuzzer fixes, mainly to reject invalid fonts
+ faster.
+
+ - Handling of raw CID fonts was broken (bug introduced in version
+ 2.6.4).
+
+ - The smooth rasterizer has been streamlined to make it faster by
+ approx. 20%.
+
+ - The `ftgrid' demo program now understands command line option
+ `-d' to give start-up design coordinates.
+
+ - The `ftdump' demo program has a new command line option `-p' to
+ dump TrueType bytecode instructions.

+Notes
+-----
+
+ The SFNT container format also provides `collections' (usually
+ having the file extension `.ttc' or `.otc'). A collection contains
+ multiple font faces that share some tables to avoid redundancy, thus
+ reducing the file size. In FreeType, elements of a collection can
+ be accessed with a proper face index.
+
+ Both the GX and the OpenType 1.8 variation fonts provide `named
+ instances'. FreeType maps them to face indices (they can also be
+ accessed with the standard MM interface).
+
+ Other font formats (not using the SFNT wrapper) also provide
+ multiple faces within one file; they are marked with an asterisk
+ (`*') in the table below.
+
+ FreeType can be configured to support Mac files (on older Mac OS
+ versions, a `file' is stored as a data and a resource fork, this is,
+ within two separate data chunks). If a file can't be opened as a
+ font, FreeType then checks whether it is a resource fork, trying to
+ extract the contained font data from either a `POST' or `sfnt'
+ resource.
+
+
+Please send additions and/or corrections to wl@gnu.org or to the
+FreeType developer's list at freetype-devel@nongnu.org (for
+subscribers only). If you can provide a font example for a format
+which isn't supported yet please send a mail too.

<p>This property can be used with <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a> also.</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>

+<p><b>Experimental</b> <b>only</b>, <b>requires</b> <b>linear</b> <b>alpha</b> <b>blending</b> <b>and</b> <b>gamma</b> <b>correction</b></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. 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>

<p>FT_ENCODING_NONE is set by the BDF and PCF drivers if the charmap is neither Unicode nor ISO-8859-1 (otherwise it is set to FT_ENCODING_UNICODE). Use <a href="ft2-bdf_fonts.html#FT_Get_BDF_Charset_ID">FT_Get_BDF_Charset_ID</a> to find out which encoding is really present.

<p>FT_ENCODING_NONE is always set (with a single exception) by the winfonts driver.

<p>When FreeType outputs a bitmap of a glyph, it really outputs an alpha coverage map. If a pixel is completely covered by a filled-in outline, the bitmap contains 0xFF at that pixel, meaning that 0xFF/0xFF fraction of that pixel is covered, meaning the pixel is 100% black (or 0% bright). If a pixel is only 50% covered (value 0x80), the pixel is made 50% black (50% bright or a middle shade of grey). 0% covered means 0% black (100% bright or white).</p>
<p>On high-DPI screens like on smartphones and tablets, the pixels are so small that their chance of being completely covered and therefore completely black are fairly good. On the low-DPI screens, however, the situation is different. The pixels are too large for most of the details of a glyph and shades of gray are the norm rather than the exception.</p>
-<p>This is relevant because all our screens have a second problem: they are not linear. 1 + 1 is not 2. Twice the value does not result in twice the brightness. When a pixel is only 50% covered, the coverage map says 50% black, and this translates to a pixel value of 128 when you use 8 bits per channel (0-255). However, this does not translate to 50% brightness for that pixel on our sRGB and gamma 2.2 screens. Due to their non-linearity, they dwell longer in the darks and only a pixel value of about 186 results in 50% brightness – 128 ends up too dark on both bright and dark backgrounds. The net result is that dark text looks burnt-out, pixely and blotchy on bright background, bright text too frail on dark backgrounds, and colored text on colored background (for example, red on green) seems to have dark halos or ‘dirt’ around it. The situation is especially ugly for diagonal stems like in ‘w’ glyph shapes where the quality of FreeType's anti-aliasing depends on the correct display of grays. On high-DPI screens where smaller, fully black pixels reign supreme, this doesn't matter, but on our low-DPI screens with all the gray shades, it does. 0% and 100% brightness are the same things in linear and non-linear space, just all the shades in-between aren't.</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>

-<p>Many CJK characters 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 Ideographic Variation Sequences (IVS), consisting of a Unicode base character and one of 240 variant selectors (U+E0100-U+E01EF), instead of further extending the already huge code range for CJK characters.</p>
-<p>An IVS is registered and unique; for further details please refer to Unicode Technical Standard #37, the Ideographic Variation Database:</p>
-<p><a href="http://www.unicode.org/reports/tr37/">http://www.unicode.org/reports/tr37/</a></p>
-<p>To date (November 2014), the character with the most variants is U+9089, having 32 such IVS.</p>
-<p>Adobe and MS decided to support IVS with a new cmap subtable (format 14). It is an odd subtable because it is not a mapping of input code points to glyphs, but contains lists of all variants supported by the font.</p>
-<p>A variant may be either ‘default’ or ‘non-default’. A default variant is the one you will get for that code point if you look it up in the standard Unicode cmap. A non-default variant is a different glyph.</p>
+<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>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>Adobe and MS decided to support both standardized and ideographic VS with a new cmap subtable (format 14). It is an odd subtable because it is not a mapping of input code points to glyphs, but contains lists of all variations supported by the font.</p>
+<p>A variation may be either ‘default’ or ‘non-default’ for a given font. A default variation is the one you will get for that code point if you look it up in the standard Unicode cmap. A non-default variation is a different glyph.</p>

<h4>note</h4>
<p>A contour that contains a single point only is represented by a ‘move to’ operation followed by ‘line to’ to the same point. In most cases, it is best to filter this out before using the outline for stroking purposes (otherwise it would result in a visible dot when round caps are used).</p>
+<p>Similarly, the function returns success for an empty outline also (doing nothing, this is, not calling any emitter); if necessary, you should filter this out, too.</p>

<p>The point coordinates sent to the emitters are the transformed version of the original coordinates (this is important for high accuracy during scan-conversion). The transformation is simple:</p>
<pre class="colored">
x' = (x << shift) - delta
- y' = (x << shift) - delta
+ y' = (y << shift) - delta
</pre>
<p>Set the values of ‘shift’ and ‘delta’ to 0 to get the original point coordinates.</p>

+<p>While FreeType's PCF 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>. Right now, there is a single property ‘no-long-family-names’ available if FreeType is compiled with PCF_CONFIG_OPTION_LONG_FAMILY_NAMES.</p>
+<p>The PCF driver's module name is ‘pcf’.</p>
+
+<div class="section">

+
+<p>If PCF_CONFIG_OPTION_LONG_FAMILY_NAMES is active while compiling FreeType, the PCF driver constructs long family names.</p>
+<p>There are many PCF 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. The improve this situation, the PCF module prepends the foundry name (plus a space) to the family name. It also checks whether there are ‘wide’ characters; all put together, family names like ‘Sony Fixed’ or ‘Misc Fixed Wide’ are constructed.</p>
+<p>If ‘no-long-family-names’ is set, this feature gets switched off.</p>
+<pre class="colored">

<h4>note</h4>
<p>This callback allows client applications to directly render the gray spans of the anti-aliased bitmap to any kind of surfaces.</p>
<p>This can be used to write anti-aliased outlines directly to a given background bitmap, and even perform translucency.</p>
-<p>Note that the ‘count’ field cannot be greater than a fixed value defined by the ‘FT_MAX_GRAY_SPANS’ configuration macro in ‘ftoption.h’. By default, this value is set to 32, which means that if there are more than 32 spans on a given scanline, the callback is called several times with the same ‘y’ parameter in order to draw all callbacks.</p>
-<p>Otherwise, the callback is only called once per scan-line, and only for those scanlines that do have ‘gray’ pixels on them.</p>

<h2>Synopsis</h2>
<p>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 <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec20">http://www.beatstamm.com/typography/RTRCh4.htm#Sec20</a>. Somewhat by definition, compatible width ClearType allows for non-linear widths, but only when the bi-level version has non-linear widths.</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>Backwards</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 backwards 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 backwards compatibility mode.</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>

-<p>Defined in FT_TRUETYPE_DRIVER_H (freetype/ftttdrv.h).</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).
- *
- * If subpixel hinting is on, many TrueType bytecode instructions behave

+<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>

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>

<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 FT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version 38 or 40 causes an ‘FT_Err_Unimplemented_Feature’ error.</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>

*
* FT_LOAD_TARGET_LIGHT ::
* A lighter hinting algorithm for gray-level modes. Many generated
* glyphs are fuzzier but better resemble their original shape. This
* is achieved by snapping glyphs to the pixel grid only vertically
- * (Y-axis), as is done by Microsoft's ClearType and Adobe's
- * proprietary font renderer. This preserves inter-glyph spacing in
+ * (Y-axis), as is done by FreeType's new CFF engine or Microsoft's

- * driver if the driver itself and the font support it or by the

+ * Advance widths are rounded to integer values; however, using the

+ * possible to get fractional advance widths for sub-pixel positioning
+ * (which is recommended to use).
+ *
+ * If configuration option AF_CONFIG_OPTION_TT_SIZE_METRICS is active,

*
+ * In general, you should stick with one rendering mode. For example,

+ * enforces a lot of recomputation for TrueType fonts, which is slow.

subtable format 2, but does not mention which platforms support

This program expects a set of directories containing good fonts, and a set
of extensions of fonts to be tested. It will randomly pick a font, copy it,
-introduce and error and then test it.

+The FreeType tests are quite basic; for each erroneous font ftrandom
- For each erroneous font it
- forks off a new tester;
- initializes the library;
- opens each font in the file;
- loads each glyph;

- extension).
- --check-outlines Call FT_Outline_Decompose on each glyph.

- --rasterize Call FT_Render_Glyph as well as loading it.
+ --rasterize Call `FT_Render_Glyph' as well as loading it.
--result <dir> This is the directory in which test files are

--test <file> Run a single test on a pre-generated testcase.
- Done in the current process so it can be debugged
- more easily.
+ This is done in the current process so it can be
+ debugged more easily.
+
+The default font extensions tested by ftrandom are
+
+ .ttf .otf .ttc .cid .pfb .pfa .bdf .pcf .pfr .fon .otb .cff
+
+The default font directory is controlled by the macro `GOOD_FONTS_DIR' in
+the source code (and can be thus specified during compilation); its default
+value is
+
+ /usr/local/share/fonts
+
+The default result directory is `results' (in the current directory).
+
+
+Compilation
+-----------
+
+Two possible solutions.
+
+. Run ftrandom within a debugging tool like `valgrind' to catch various
+ memory issues.
+
+. Compile FreeType with sanitizer flags as provided by gcc or clang, for
+ example, then link it with ftrandom.
