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. The solution is to cast to `Bar*' too, with + `(Bar*)(void*)x' as the result -- this is what the patch does. + + * include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP), + include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove + cast on lvalue, use a temporary pointer instead. + Cast temporarily to (void*) to not break strict aliasing. + + * include/freetype/internal/ftmemory.h (FT_MEM_ALLOC, + FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE), + src/base/ftglyph.c (FT_Glyph_To_Bitmap): Cast temporarily to (void*) + to not break strict aliasing. + + * src/base/ftinit.c (FT_USE_MODULE): Fix wrong type information. + + * builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing. + +2005-05-23 David Turner <dturner@freetype.org> + + Fix Savannah bug #12213 (incorrect behaviour of the cache sub-system + in low-memory conditions). + + * include/freetype/cache/ftccache.h (FTC_CACHE_TRYLOOP, + FTC_CACHE_TRYLOOP_END): New macros. + + * src/cache/ftccache.c (FTC_Cache_NewNode), src/cache/ftcsbits.c + (ftc_snode_compare): Use FT_CACHE_TRYLOOP and FTC_CACHE_TRYLOOP_END. + +2005-05-23 Werner Lemberg <wl@gnu.org> + + * src/base/rules.mk (BASE_SRC): Don't add ftsynth.c here but... + (BASE_EXT_SRC): Here. + +2005-05-22 Werner Lemberg <wl@gnu.org> + + * src/base/ftrfork.c (raccess_guess_apple_generic): Mark + `version_number' and `entry_length' as unused. + (raccess_guess_linux_double_from_file_name): Remove `memory'. + (raccess_make_file_name): Mark `error' as unused. + + * src/bdf/bdflib.c (_bdf_parse_properties): Remove `memory'. + + * src/cid/cidobjs.c (cid_face_init): Remove `psnames'. + + * src/sfnt/sfobjs.c (sfnt_load_face): Remove `memory'. + + * src/truetype/ttgxvar.c (ft_var_readpackedpoints, + ft_var_readpackeddeltas, ft_var_load_avar): Mark `error' as unused. + + * src/base/rules.mk (BASE_SRC): Add ftsynth.c. + +2005-05-21 David Turner <david@freetype.org> + + * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Fix a bug that + produced unpleasant artefacts when trying to embolden very sharp + corners. + +2005-05-20 Werner Lemberg <wl@gnu.org> + + * docs/CHANGES: Updated. + +2005-05-20 Chia I Wu <b90201047@ntu.edu.tw> + + * src/base/ftbitmap.c: Don't include FT_FREETYPE_H and FT_IMAGE_H + but FT_BITMAP_H. + (FT_Bitmap_Copy): New function (from ftglyph.c). + + * include/freetype/ftbitmap.h (FT_Bitmap_Copy): New public + definition. + + * src/base/ftglyph.c: Include FT_BITMAP_H. + (ft_bitmap_copy): Move to ftbitmap.c. + (ft_bitmap_glyph_init): Remove `memory' variable. + Create new bitmap object if FT_GLYPH_OWN_BITMAP isn't set. + (ft_bitmap_glyph_copy): Use FT_Bitmap_Copy. + (ft_bitmap_glyph_done): Use FT_Bitmap_Done. + (ft_outline_glyph_init): Use FT_Outline_Copy. + + * src/base/ftoutln.c (FT_Outline_Copy): Handle source == target. + (FT_Outline_Done_Internal): Check for valid `memory' pointer. + (FT_Outline_Translate, FT_Outline_Reverse, FT_Outline_Render, + FT_Outline_Transform): Check for valid `outline' pointer. + + * src/base/ftobjs.c (FT_New_GlyphSlot): Prepend glyph slot to + face->glyph, otherwise a new second glyph slot cannot be created. + (FT_Done_GlyphSlot): Fix memory leak. + (FT_Open_Face): Updated -- face->glyph is already managed by + FT_New_GlyphSlot. + + * src/type42/t42objs.c (T42_GlyphSlot_Done): Updated. + +2005-05-20 Kirill Smelkov <kirr@mns.spb.ru> + + * include/freetype/ftimage.h (FT_Raster_Params), + include/freetype/ftoutln.h (FT_Outline_Translate, + FT_Outline_Transform), src/base/ftoutln.c (FT_Outline_Translate, + FT_Outline_Transform): Decorate parameters with `const' where + appropriate. + Update all callers. + + * src/raster/ftraster.c (ft_black_reset), src/smooth/ftgrays.c + (gray_raster_reset): Remove `const' from `pool_base' argument. + +2005-05-18 Kirill Smelkov <kirr@mns.spb.ru> + + * src/raster/ftmisc.h: New file.

If this allocation fails, the + user-supplied stream is not returned to `FT_Open_Face` and never + closed. Moreover, the user cannot detect this situation: all they + see is that `FT_Open_Face` returns `FT_Err_Out_Of_Memory`, but that + can also happen after a different allocation fails within the main + body of `FT_Open_Face`, when the user's stream has already been + closed by `FT_Open_Face`. It is plausible that the user stream's + `close` method frees memory allocated for the stream object itself, + so the user cannot defensively free it upon `FT_Open_Face` failure + lest it ends up doubly freed. All in all, this ends up leaking the + memory/resources used by user's stream. + + Furthermore, `FT_Stream_New` simply returns an error if the + `FT_OPEN_XXX` flags are unsupported, which can mean either an + invalid combination of flags or a perfectly innocent + `FT_OPEN_STREAM` on a FreeType build that lacks stream support. + With this patch, the user-supplied stream is closed even in these + cases, so the user can be sure that if `FT_Open_Face` failed, the + stream is definitely closed. + + * src/base/ftobjs.c (FT_Stream_New): Don't allocate a buffer + unnecessarily. + Move error-handling code to make the control flow more obvious. + Close user-supplied stream if the flags are unsupported. + `FT_Stream_Open` always sets `pathname.pointer`, so remove the + redundant (re)assignment. None of the `FT_Stream_Open...` functions + uses `stream->memory`, so keep just one assignment at the end, + shared among all possible control flow paths. + ('Unsupported flags' that may need a stream closure can be either an + invalid combination of multiple `FT_OPEN_XXX` mode flags or a clean + `FT_OPEN_STREAM` flag on a FreeType build that lacks stream + support.) + +2021-07-13 Oleg Oshmyan <chortos@inbox.lv> + + [base] Reject combinations of incompatible `FT_OPEN_XXX` flags. + + The three modes are mutually exclusive, and the documentation of the + `FT_OPEN_XXX` constants notes this.

FreeType has attempted to prevent their use in the glyph + program, but they were still allowed in glyph programs if defined in + a function defined in 'prep' or 'fpgm' and called from the glyph + program. + + Similarly, `IDEF` instructions are specified not to be able to + modify any existing instruction. FreeType has attempted to prevent + their use in the glyph program, but they can still be used like + `FDEF`. + + This change stores the initial bytecode range type and disallows the + use of `FDEF` and `IDEF` while running the glyph program. + + Most other state is copied from the `TT_Size` into the execution + context. However, it is possible for a glyph program to use `WS` to + write to the storage area or `WCVTP`, `WCVTF`, and `DELTAC[123]` to + write to the control value table. + + Allowing any change to the global state from the glyph program is + problematic as the outlines of any given glyph may change based on + the order the glyphs are loaded or even how many times they are + loaded. There exist fonts that write to the storage area or the + control value table in the glyph program, so their use should not be + an error. + + Possible solutions to using these in the glyph program are + + * ignore the writes; + * value-level copy on write, discard modified values when finished; + * array-level copy on write, discard the copy when finished; + * array-level copy up-front. + + Ignoring the writes may break otherwise good uses. A full copy + up-front was implemented, but was quite heavy as even well behaved + fonts required a full copy and the memory management that goes along + with it.

However, this value + is defined in the PDF and PostScript specs, and that algorithm is + better than the one FreeType currently uses: + + FreeType: Use the middle of the bounding box as the X coordinate + of the vertical origin. + + Adobe PDF spec: Use the middle of the horizontal advance vector as + the X coordinate of the vertical origin. + + FreeType's algorithm goes wrong if you have a really small glyph + (like the full-width, circle-like dot at the end of the sentence, as + used in CJK scripts) with large bearings. With the FreeType + algorithm this dot gets centered on the baseline; with the PDF + algorithm it gets the correct location (in the top right). Note + that this is a serious issue, it's like printing the dot at the end + of a Roman sentence at the center of the textline instead of on the + baseline like it should. So i believe the PDF spec's algorithm + should be used in FreeType as well. + + The `vertBearingY' value for such small glyphs is also very strange + if no `vmtx' information is present, since the height of the bbox is + not representable for the height of the glyph visually (the + whitespace up to the baseline is part of the glyph).

However, there are fonts like `pala.ttf' + which additionally contain this instruction in the hinting code of + some glyphs (but not all).

Consider two unit vectors (1,0) and (.6,.8) + for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666. + These vectors are stored as (0x4000,0) and (0x2666,0x3333) after + rounding and F_dot_P is assigned 0x26660000. The lower bits were + already lost while rounding the unit vector components. + + Besides code simplification, this change can lead to better + performance when FT_MulDiv with the scaled-down F_dot_P is less + likely to use the costly 64-bit path.

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 <wl@gnu.org> + + [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 + + https://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> + + [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 <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 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.
