- Fix Savannah bug #35660.
+ * builds/toplevel.mk (dist): Use older POSIX standard for `tar'.
- For some divisions, we use casts to 32bit entities. Always guard
- against division by zero with these casts also.
+ Apparently, BSD tar isn't capable yet of handling POSIX-1.2001
+ (contrary to GNU tar), so force the POSIX-1.1988 format.
- * src/base/ftcalc.c (ft_div64by32): Remove redundant cast.
- (FT_MulDiv, FT_MulDiv_No_Round): Add 32bit cast.

- [bdf] Fix Savannah bug #35658.
+ [otvalid] Fix a naming convention conflicting with ftvalid.
- * src/bdf/bdflib.c (_bdf_list_split): Initialize `field' elements
- properly.
+ Some prototypes in ftvalid.h use `valid' for the variables
+ typed as FT_Validator. Their implementations in src/base/
+ ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar.
-2012-03-01 Werner Lemberg <wl@gnu.org>
+ Some macros in otvcommn.h assume the exist of the variable
+ `valid' typed as OTV_Validator in the caller.
- [psaux] Fix Savannah bug #35657.
+ Mixing these two conventions cause invalid pointer conversion
+ and unexpected SEGV in longjmp. To prevent it, all variables
+ typed as OTV_Validator are renamed to `otvalid'.
- If in function `skip_spaces' the routine `skip_comment' comes to the
- end of buffer, `cur' is still increased by one, so we need to check
- for `p >= limit' and not `p == limit'.
+ * src/otvalid/otvcommn.h: Replace `valid' by `otvalid'.
+ * src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c,
+ otvgsub.c, otvjstf.c, otvmath.c}: Replace `valid' by `otvalid'
+ if it is typed as OTV_Validator.
- * src/psaux/psconv.c (PS_Conv_Strtol, PS_Conv_ToFixed,
- PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Fix boundary checking.

- five `field' elements.
+ Work around `features' of X11's `pcfWriteFont' and `pcfReadFont'
+ functions. Since the PCF format doesn't have an official
+ specification, we have to exactly follow these functions' behaviour.

+ element. Instead, assign real size.
- * src/bdf/bdflib.c (_bdf_parse_glyphs) <DWIDTH, BBX>: Abort if
- _BDF_ENCODING isn't set. We need this because access to the `glyph'

- Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were

- Because these macros are used at the end of the module
- interface (e.g. ttdriver.c) and the wrapper source to build
- a module as a single object (e.g. truetype.c) includes
- the PIC file (e.g. ttpic.c) before the module interface,
- these macros are expanded AFTER xxx_pic_{free,init} body
- when the modules are built as single object.
- The declaration after the implementation causes the redundant
- declaration warnings, so the declarations are moved to module
- PIC headers (e.g. ttpic.h). Separating to other header files
- are needed for multi build.

- Darwin & Carbon-dependent codes, these macros can be unified.
- FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON

- The main problems
- -----------------
+2014-10-16 Behdad Esfahbod <behdad@behdad.org>
+ Werner Lemberg <wl@gnu.org>
- o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
- joins (not bevel joins) were generated. Indeed, the meanings of
- `miter' and `bevel' were incorrectly reversed (consistently) in
- both the code and comments.
+ [cff] Add `CFF_CONFIG_OPTION_DARKENING_PARAMETERS' config macro.
- o The way bevel joins were constructed (whether specified
- explicitly, or created as a result of exceeding the miter limit)
- did not match what is required for stroked text in PostScript or
- PDF.
+ * devel/ftoption.h, include/config/ftoption.h
+ (CFF_CONFIG_OPTION_DARKENING_PARAMETERS): New macro.
- The main fixes
- --------------
+ * src/cff/cffobjs.c (SET_DARKENING_PARAMETERS,
+ SET_DARKENING_PARAMETERS_0): New macros.
+ (cff_driver_init): Use new macros.
- o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
+2014-10-14 Alexei Podtelezhnikov <apodtele@gmail.com>
- o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
- introduced to support PostScript and PDF miter joins.
+ [truetype] Limit delta shift range.
- o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
- alias for FT_STROKER_LINEJOIN_MITER.
+ The valid range for delta shift is zero through six. Negative values
+ are invalid according to
- Additionally, a variety of stroking errors have been fixed. These
- would cause various artifacts (including points `at infinity'),
- especially when stroking poor quality fonts.
+ https://developer.apple.com/fonts/TrueType-Reference-Manual/RM04/Chap4.html#delta%20shift
- See
+ * src/truetype/ttobjs.h (delta_shift, delta_base): Make unsigned.
+ * src/truetype/ttinterp.h (DO_SDS): Throw an error if `delta_shift'
+ is out of range.
+ (Ins_DELTAP, Ins_DELTAC): Optimize for valid `delta_shift'.

+2014-10-16 Werner Lemberg <wl@gnu.org>
- for example documents. The FreeType stroker now produces results
- very similar to that produced by GhostScript and Distiller for these
- fonts.
+ A better fix for Savannah bug #43392.
+ Suggested by Doug Felt <dougfelt@gmail.com>.
- Other problems
- --------------
+ * src/sfnt/ttsbit.c (tt_sbit_decoder_load_metrics): Set
+ `vertAdvance' to zero...
- The following problems have been resolved:
+ * src/truetype/ttgload.c (TT_Load_Glyph): ... and set here a default
+ value for `vertAdvance' based on `linearVertAdvance' in case
+ `vertAdvance' is zero. Note that the previous computed ad-hoc value
+ for `linearVertAdvance' was apparently not tested in a real-life
+ situation.
- o Inside corners could be generated incorrectly. Intersecting the
- inside corner could cause a missing triangular area and other
- effects.
+2014-10-14 David Weiß <David.Weiss@ptvgroup.com>
- The intersection point can only be used if the join is between
- two lines and both lines are long enough. The `optimization'
- condition in `ft_stroker_inside' has been corrected; this
- requires the line length to be passed into various functions and
- stored in `FT_StrokerRec'.
+ [build] Better optimization settings for vc2010 solution file.
- o Incorrect cubic curves could be generated. The angle
- calculations in `FT_Stroker_CubicTo' have been corrected to
- handle the case of the curve crossing the +/-PI direction.
+ * builds/windows/vc2010/freetype.sln,
+ builds/windows/vc2010/freetype.vcxproj: Updated.
- o If the border radius was greater than the radius of curvature of
- a curve, then the negative sector would end up outside (not
- inside) the border. This situation is now recognized and the
- negative sector is circumnavigated in the opposite direction.
- (If round line joins are being used, this code is disabled
- because the line join will always cover the negative sector.)
+2014-10-14 Werner Lemberg <wl@gnu.org>
- o When a curve is split, the arcs may not join smoothly (especially
- if the curve turns sharply back on itself). Changes in
- direction between adjacent arcs were not handled. A round
- corner is now added if the deviation from one arc to the next is
- greater than a suitable threshold.
+ [autofit] Adjust Devenagari character range.
- o The current direction wasn't retained if a the outline contained
- a zero length lineto or a curve that was determined to be
- `basically a point'. This could cause a spurious join to be
- added.
+ * src/autofit/afranges.c (af_deva_uniranges): Omit characters that
+ are common to all other Indic scripts.
- o Cubics with close control points could be mishandled. All eight
- cases are now distinguished correctly.

+ If the distances AB and CD are large, point B wasn't previously

-2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+ To improve that, another pass gets now performed before calling

- Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer.
+ Additionally, distances of near points are now accumulated, which

-2010-08-06 Yuriy Kaminskiy <yumkam@mail.ru>
+ The fragmented resources in Suitcase and .dfont should be reordered
+ when `POST' resource for Type1 is being restored, but reordering of
+ sfnt resources induces the different face order. Now the ordering
+ is restricted to `POST' resource only, to prevent the different
+ order issue (e.g. the face index in the fontconfig cache generated
+ with Carbon framework is incompatible with that by FreeType 2
+ without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung.

+ as the author told me in private communication.
- Previously we discovered fonts which used `setcurrentpoint' to set
- the initial point of a contour to 0,0. This caused FreeType to
- raise an error, because the `setcurrentpoint' operator is only
- supposed to be used with the results from an OtherSubr subroutine.
+2013-10-19 Werner Lemberg <wl@gnu.org>
- This was fixed by simply ignoring the error and carrying on.
+ [autofit] s/SMALL_TOP/X_HEIGHT/.
- Now we have found a font which uses setcurrentpoint to actually
- establish a non-zero point for a contour during the course of a
- glyph program. FWIW, these files may be produced by an application
- called `Intaglio' on the Mac, when converting TrueType fonts to
- Type 1.
+ * src/autofit/afblue.dat: Updated.
- The fix allows the new invalid behaviour, the old invalid behaviour
- and real proper usage of the operator to work the same way as Adobe
- interpreters apparently do.
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
- (t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top
- two elements of the stack to establish unconditionally the current x
- and y coordinates.
+ * src/autofit/aflatin.c, src/autofit/aflatin.h,
+ src/autofit/atlatin2.c: Updated.
- Make the `flex' subroutine handling (OtherSubr 0) put the current
- x,y coordinates onto the stack, instead of two dummy uninitialised
- values.

+ * src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.

+ * src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount.
+
+ This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect
+ is to use a previous darkening amount when producing an unhinted,
+ unscaled outline. This can cause autohint samples in ftgrid and
+ ftview to be based on darkened CFF outlines instead of unhinted,
+ undarkened ones.
+
+2013-09-29 Dave Arnold <darnold@adobe.com>
+
+ Fix Savannah bug #39295.
+
+ The bug was caused by switching to the initial hintmap (the one in
+ effect when `moveto' executes) just before drawing the final element
+ in the charstring. This ensured that the path was closed (in both
+ Character Space and Device Space). But if the final element was a
+ curve and if the final hintmap was different enough from the initial
+ one, then the curve was visibly distorted.
+
+ The first part of the fix is to draw the final curve using the final
+ hintmap as specified by the charstring. This corrects the
+ distortion but does not ensure closing in Device Space. It may
+ require the rasterizer to automatically generate an extra closing
+ line. Depending on the hintmap differences, this line could be from
+ zero to a couple pixels in length.
+
+ The second part of the fix covers the case where the charstring
+ subpath is closed with an explicit line. We now modify that line's
+ end point to avoid the distortion.
+
+ Some glyphs in the bug report font (TexGyreHeros-Regular) that show
+ the change are:
+
+ 25ppem S (98)
+ 24ppem eight (52)
+ 25.5ppem p (85)
+
+ Curves at the *end* of a subpath are no longer distorted. However,
+ some of these glyphs have bad hint substitutions in the middle of a
+ subpath, and these are not affected.
+
+ The patch has been tested with a set of 106 fonts that shipped with
+ Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
+ Google Fonts. There are 1.5 million glyphs, of which some 20k are
+ changed with the fix. A sampling of a few hundred of these changes
+ have been examined more closely, and the changes look good (or at
+ least acceptable).
+
+ * src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'
+ to indicate that we synthesize a closepath line.
+
+ * src/cff/cf2hints.c (cf2_glyphpath_init): Updated.
+ (cf2_glyphpath_pushPrevElem): If closing, use first hint map (for
+ `lineto' operator) and adjust hint zone.

+ (cf2_glyphpath_lineTo): Take care of synthesized closing lines. In
+ particular, shift the detection of zero-length lines from character
+ space to device space.
+ (cf2_glyphpath_closeOpenPath): Remove assertion.

+
+ [autofit] Introduce data file for blue strings.
+
+ The idea is to have a central file which gets processed by a Perl
+ script to create proper `.c' and `.h' files using templates. There
+ are two other reasons to do that:
+
+ . The data file should be easily readable. We use UTF-8 encoding
+ which then gets converted to single bytes.
+
+ . Since the number of supported scripts will increase soon, the
+ current usage of blue string arrays is a waste of space. Using
+ the Perl script it is possible to imitate jagged arrays,
+ defining enumeration constants as offsets into the arrays.
+
+ This commit only adds files without changing any functionality.

+ * src/autofit/afblue.dat: New data file.

+
+ Speed up ARMv7 support.
+
+ When building for ARMv7 with thumb2 instructions, the optimized
+ `FT_MulFix_arm' assembly routine was not being used.
+
+ The reason for this is in the `ftconfig.h' header, namely:
+
+ - The assembly routine uses the `smull' instruction which is not
+ available when generating Thumb-1 machine code. It is available
+ in Thumb-2 mode, though.
+
+ - The header was written a long time ago before Thumb-2 became
+ widely popular (e.g. with Android). So it simply doesn't use the
+ assembly routine if the `__thumb__' built-in macro is defined.
+
+ - When compiling in Thumb-2 mode, the compiler will define both
+ `__thumb__' and `__thumb2__'.
+
+ By checking for `(__thumb2__ || !__thumb__)', we ensure that the
+ assembly routine is only avoided when generating Thumb-1 code.
