This glyph is a composite; - the first component, `E', has an advance width of 1366 font units, - while the advance width of the composite itself (which looks like - uppercase `E' with dieresis) is 1367 font units. I think this is - actually a bug in the font itself, because there is no reason that - this glyph has not the same width as uppercase `E' without the - dieresis. Anyway, it helped identify this problem. - - Using the TrueType hinter, the correct value (1367) of `afii10023' - was returned, but the autohinter mysteriously returned 1366. - - Digging in the code showed that the autohinter recursively calls - FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load - flag. However, the `linearHoriAdvance' field is still returned as a - scaled value. To avoid scaling twice, the old code in autofit reset - `linearHoriAdvance', using the `horiAdvance' field. This seemed to - work since FT_LOAD_NO_SCALE was in use, but it failed actually, - because `horiAdvance' is defined as the distance of the first - subglyph's phantom points, which in turn are initialized using the - advance width of the first subglyph. And as the given example - shows, these widths can differ. - - * src/autofit/afloader.c (af_loader_load_g): Temporarily set - FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled - values for the linear advance widths. - -2012-03-10 Werner Lemberg - - [truetype] Fix SSW instruction. - - * src/truetype/ttinterp.c (DO_SSW): SSW *does* use font units.

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 Ä°smail Dönmez - - * builds/toplevel.mk: We use git, not CVS, thus skip `.gitignore'. - -2011-06-29 Werner Lemberg - - [bdf] 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 - - * 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 - - * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Fix change - from 2011-05-04. - -2011-06-19 suzuki toshiya - - [gxvalid] make the `prop' validation tracing verbose. - - * src/gxvalid/gxvprop.c: Add tracing messages for errors. - -2011-06-19 suzuki toshiya - - [autogen.sh] Reflect environment variable LIBTOOLIZE. - -2011-06-18 Werner Lemberg - - Update license documentation. - - * docs/GPL.TXT: Renamed to... - * docs/GPLv2.TXT: This. - - * docs/LICENSE.TXT: Updated. - -2011-06-14 suzuki toshiya - - 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'.

If you simply say `x' or `(Bar*)x', then the C compiler - would warn you that type casting incompatible pointer types breaks - strict-aliasing. The solution is to cast to `(void*)' instead which - is the generic pointer type, so the compiler knows that it should - make no strict-aliasing assumption on `x'. But the problem with - `(void*)x' is that seems like in C++, unlike C, `void*' is not a - generic pointer type and assigning `void*' to `Bar*' without a cast - causes an error.
