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. @@ -286,7 +535,7 @@ [autofit] Remove unused structure member. - * src/autofit/afhints.h (AF_SegmentRec): Remove `contour'. + * src/autofit/afhints.h (AF_SegmentRec): Remove `contour'. * src/autofit/aflatin.c (af_latin_hints_compute_segments), src/autofit/aflatin2.c (af_latin2_hints_compute_segments): Updated. @@ -312,7 +561,7 @@ [mac] Conditionalize the inclusion of `AvailabilityMacros.h'. - The native SDK on earliest Mac OS X (10.0-10.1) did not have + The native SDK on earliest Mac OS X (10.0-10.1) did not have `AvailabilityMacros.h'.
