Indeed, the meanings of + `miter' and `bevel' were incorrectly reversed (consistently) in + both the code and comments. + + 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. + + The main fixes + -------------- + + o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected. + + o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been + introduced to support PostScript and PDF miter joins. + + o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an + alias for FT_STROKER_LINEJOIN_MITER. + + Additionally, a variety of stroking errors have been fixed. These + would cause various artifacts (including points `at infinity'), + especially when stroking poor quality fonts. + + See + + http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html + + for example documents. The FreeType stroker now produces results + very similar to that produced by GhostScript and Distiller for these + fonts. + + Other problems + -------------- + + The following problems have been resolved: + + o Inside corners could be generated incorrectly. Intersecting the + inside corner could cause a missing triangular area and other + effects. + + 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'. + + 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. + + 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.) + + 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. + + 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. + + o Cubics with close control points could be mishandled. All eight + cases are now distinguished correctly. + + Other improvements + ------------------ + + o Borders for cubic curves could be too `flat'. + FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent + this. + + o The handling and use of movable points has been simplified a + little. + + o Various values are now computed only if the results are actually + needed. + + o The directions of the outer and inner borders have been swapped, + as recommended by Graham Asher. + + * src/base/ftstroke.c: Revised. + * include/freetype/ftstroke.h: Updated. + +2011-06-30 İsmail Dönmez <ismail@namtrac.org> + + * builds/toplevel.mk: We use git, not CVS, thus skip `.gitignore'. + +2011-06-29 Werner Lemberg <wl@gnu.org> + + Fix Savannah bug #33663. + + * src/bdf/bdflib.c (_bdf_parse_glyphs): Handle negative values for + ENCODING correctly. + + * docs/CHANGES: Document it. + +2011-06-24 Werner Lemberg <wl@gnu.org> + + * Version 2.4.5 released. + ========================= + + + Tag sources with `VER-2-4-5'. + + * docs/CHANGES: Updated. + + * docs/VERSION.DLL: Update documentation and bump version number to + 2.4.5 + + * README, Jamfile (RefDoc), + builds/win32/vc2005/freetype.vcproj, builds/win32/vc2005/index.html, + builds/win32/vc2008/freetype.vcproj, builds/win32/vc2008/index.html, + builds/win32/vc2010/freetype.vcxproj, builds/win32/vc2010/index.html, + builds/win32/visualc/freetype.dsp, + builds/win32/visualc/freetype.vcproj, + builds/win32/visualc/index.html, builds/win32/visualce/freetype.dsp, + builds/win32/visualce/freetype.vcproj, + builds/win32/visualce/index.html, + builds/wince/vc2005-ce/freetype.vcproj, + builds/wince/vc2005-ce/index.html, + builds/wince/vc2008-ce/freetype.vcproj, + builds/wince/vc2008-ce/index.html: s/2.4.4/2.4.5/, s/244/245/. + + * include/freetype/freetype.h (FREETYPE_PATCH): Set to 5. + + * builds/unix/configure.raw (version_info): Set to 13:0:7. + +2011-06-20 Werner Lemberg <wl@gnu.org> + + * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Fix change + from 2011-05-04. + +2011-06-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> + + [gxvalid] make the `prop' validation tracing verbose. + + * src/gxvalid/gxvprop.c: Add tracing messages for errors. + +2011-06-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> + + [autogen.sh] Reflect environment variable LIBTOOLIZE. + +2011-06-18 Werner Lemberg <wl@gnu.org> + + Update license documentation. + + * docs/GPL.TXT: Renamed to... + * docs/GPLv2.TXT: This. + + * docs/LICENSE.TXT: Updated. + +2011-06-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> + + Fix g++4.6 compiler warnings in module drivers. + + The background is same with previous commit. + + * src/truetype/ttgxvar.c (ft_var_readpackedpoints): + Init `points'.

This caused FreeType to + raise an error, because the `setcurrentpoint' operator is only + supposed to be used with the results from an OtherSubr subroutine. + + This was fixed by simply ignoring the error and carrying on. + + 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. + + 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. + + (t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top + two elements of the stack to establish unconditionally the current x + and y coordinates. + + Make the `flex' subroutine handling (OtherSubr 0) put the current + x,y coordinates onto the stack, instead of two dummy uninitialised + values. + +2010-04-14 Ken Sharp <ken.sharp@artifex.com> + + Fix Savannah bug #29444. + + * src/psaux/psobjs.c (t1_builder_start_point): Accept (invalid) + `lineto' immediately after `hsbw', in accordance with Acrobat, GS, + and others. + +2010-04-14 Michał Cichoń <thedmd@artifexmundi.com> + + Fix Savannah bug #27999. + + * src/cache/ftcmanag.c (FTC_Manager_RemoveFaceID): Only remove + selected entry, not all. + +2010-04-06 Jonathan Kew <jfkthame@gmail.com> + + Add overflow check to `fvar' table. + + * src/truetype/ttgxvar.c (TT_Get_MM_Var): Check axis and instance + count. + +2010-04-05 Ken Sharp <ken.sharp@artifex.com> + + Fix Savannah bug #29335. + + * src/raster/ftraster.c (Line_Up): Use slow multiplication to + prevent overflow.
