-
-2010-02-10 Ken Sharp <ken.sharp@artifex.com>
-
- Really fix Savannah bug #28678 (part 1).
-
- After long discussion, we now consider the character width vector
- (wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
- direction only. For example, if you are using the horizontal
- writing direction, you get the horizontal and vertical components of
- the advance width for this direction. Note that OpenType and CFF fonts
- don't have such a vertical component; instead, the GPOS table can be
- used to generate two-dimensional advance widths (but this isn't
- handled by FreeType).

-2010-01-08 Ken Sharp <ken.sharp@artifex.com>
-
- Fix Savannah bug #28521.
-
- Issue #28226 involved a work-around for a font which used the
- `setcurrentpoint' operator in an invalid way; this operator is only
- supposed to be used with the result of OtherSubrs, and the font used
- it directly. The supplied patch removed the block of code which
- checked this usage entirely.
-
- This turns out to be a Bad Thing. If `setcurrentpoint' is being
- used correctly it should reset the flex flag in the decoder. If we
- don't do this then the flag never gets reset and we omit any further
- contours from the glyph (at least until we close the path or
- similar).

- Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
- This fixes Savannah bug #28226.
+2010-10-28 Werner Lemberg <wl@gnu.org>
- At least two wild PostScript files of unknown provenance contain
- Type 1 fonts, apparently converted from TrueType fonts in earlier
- PDF versions of the files, which use the `setcurrentpoint' operator
- inappropriately.
+ [ftraster] Minor fixes.
- FreeType currently throws an error in this case, but Ghostscript and
- Adobe Distiller both accept the fonts and ignore the problem. This
- commit #ifdefs out the check so PostScript interpreters using
- FreeType can render these files.
+ Reported by Tom Bishop <wenlin@wenlin.com>.
- The specification says `setcurrentpoint' should only be used to set
- the point after a `Subr' call, but these fonts use it to set the
- initial point to (0,0). Unnecessarily so, as they correctly use an
- `hsbw' operation which implicitly sets the initial point.

+ MacOS X/Darwin kernel supports a few tricky methods to access
+ a resource fork via ANSI C or POSIX interface. Current resource
+ fork accessor tries all possible methods to support all kernels.
+ But if a method could open a resource fork but no font is found,
+ there is no need to try other methods older than tested method.
+ To determine whether the rule index is for Darwin VFS, a local
+ function ftrfork.c::raccess_rule_by_darwin_vfs() is introduced.
+ To use this function in ftobjs.c etc but it should be inlined,
+ it is exposed by ftbase.h.
-2009-11-03 Bram Tassyns <bramt@enfocus.be>
+ * src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify

- Improve vertical metrics calculation (Savannah bug #27364).
+ This fixes Savannah bug #30798, reported by Robert Święcki.
- The calculation of `vertBearingX' is not defined in the OTF font
- spec so FreeType does a `best effort' attempt. However, this value
- is defined in the PDF and PostScript specs, and that algorithm is
- better than the one FreeType currently uses:
+2010-08-29 Werner Lemberg <wl@gnu.org>
- FreeType: Use the middle of the bounding box as the X coordinate
- of the vertical origin.
+ [ftraster] Pacify compiler.
- Adobe PDF spec: Use the middle of the horizontal advance vector as
- the X coordinate of the vertical origin.
+ * src/raster/ftraster.c (ft_black_new) [_STANDALONE_]: `memory' is
+ not used.
- 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

- 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). The fix also
- includes some code for a better estimate of `vertBearingY'.

- Use 16.16 format while parsing Type 1 charstrings.
- This fixes Savannah bug #26867.
-
- Previously, only integers have been used which can lead to serious
- rounding errors.
-
- However, fractional values are only used internally; after the
- charstrings (of either Type 1 or 2) have been processed, the
- resulting coordinates get rounded to integers currently -- before
- applying scaling. This should be fixed; at the same time a new load
- flag should be introduced, to be used in combination with
- FT_LOAD_NO_SCALE, which indicates that font units are returned in

-
- Fix B/W rasterization of subglyphs with different drop-out modes.
-
- Normally, the SCANMODE instruction (if present) to set the drop-out
- mode in a TrueType font is located in the `prep' table only and thus
- valid for all glyphs. However, there are fonts like `pala.ttf'
- which additionally contain this instruction in the hinting code of
- some glyphs (but not all). As a result it can happen that a
- composite glyph needs multiple drop-out modes for its subglyphs
- since the rendering state gets reset for each subglyph.
-
- FreeType collects the hinted outlines from all subglyphs, then it
- sends the data to the rasterizer. It also sends the drop-out mode
- -- after hinting has been applied -- and here is the error: It sends
- the drop-out mode of the last subglyph only; drop-out modes of all
- other subglyphs are lost.
-
- This patch fixes the problem; it adds a second, alternative
- mechanism to pass the drop-out mode: For each contour, the
- rasterizer now checks the first `tags' array element. If bit 2 is
- set, bits 5-7 contain the contour's drop-out mode, overriding the
- global drop-out mode.
-
- * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.
-
- * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in
- `tags[0]'.

-
- Improve scan conversion rules 4 and 6.
-
- Two new constraints are introduced to better identify a `stub' -- a
- concept which is only vaguely described in the OpenType
- specification. The old code was too rigorous and suppressed more
- pixel than it should.
-
- . The intersection of the two profiles with the scanline is less
- than a half pixel. Code related to this was already present in
- the sources but has been commented out.
-
- . The endpoint of the original contour forming a profile has a
- distance (`overshoot') less than half a pixel to the scanline.
-
- Note that the two additional conditions fix almost all differences
- to the Windows rasterizer, but some problematic cases remain.
-
- * src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New
- macros for the `flags' field in the `TProfile' structure.
- (IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros.
- (New_Profile, End_Profile): Pass overshoot flag as an argument and
- set it accordingly.
- Update callers.
- (Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement the two new
- constraints.
-

-
- Increase precision for B/W rasterizer.
-
- * src/raster/ftraster.c (Set_High_Precision): Add two more bits to
- the precision. This corrects rendering of some small glyphs, for
- example, glyph `xi' in verdana.ttf at 13 ppem. Testing with ftbench
- on my GNU/Linux box I don't see a performance degradation.

-
- * src/sfnt/rules.mk (SFNT_DRV_H): Add ttsbit0.c.
-
-2009-03-09 Alexey Kryukov <anagnost@yandex.ru>
-
- Fix handling of EBDT formats 8 and 9 (part 2).
-
- This patch fixes the following problems in ttsbit0.c:
-
- . Bitmaps for compound glyphs were never allocated.
-
- . `SBitDecoder' refused to load metrics if some other metrics have
- already been loaded. This condition certainly makes no sense for
- recursive calls, so I've just disabled it. Another possibility
- would be resetting `decoder->metrics_loaded' to false before
- loading each composite component. However, we must restore the
- original metrics after finishing the recursion; otherwise we can
- get a misaligned glyph.
-
- . `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',
- causing some glyph components to be shifted too far to the right
- (especially noticeable for small sizes).
-
- Note that support for grayscale bitmaps (not necessarily compound) is
- completely broken in ttsbit0.c.
-
- * src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.
- (tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case
- of `h == height'.
- (tt_sbit_decoder_load_compound): Reset metrics after loading
- components.
- Allocate bitmap.

- FT_USE_MODULE declares things as:
-
- extern const FT_Module_Class
-
- (or similar for C++). However, the actual types of the variables
- being declared are often different, e.g., FT_Driver_ClassRec or
- FT_Renderer_Class. (Some are, indeed, FT_Module_Class.)
-
- This works with most C compilers (since those structs begin with an
- FT_Module_Class struct), but technically it's undefined behavior.
-
- To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
- paragraph 2:
-
- All declarations that refer to the same object or function shall
- have compatible type; otherwise, the behavior is undefined.
-
- (And they are not compatible types.)
-
- Most C compilers don't reject (or even detect!) code which has this
- issue, but the GCC LTO development branch compiler does. (It
- outputs the types of the objects while generating .o files, along
- with a bunch of other information, then compares them when doing the
- final link-time code generation pass.)
-

-
- Generalize the concept of `tricky' fonts by introducing
- FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
- engine is necessary for correct rendering.
-
- At the same time, slightly modify the behaviour of tricky fonts:
- FT_LOAD_NO_HINTING is now ignored. To really force raw loading
- of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
- FT_LOAD_NO_AUTOHINT must be used.
-
- Finally, tricky TrueType fonts always use the bytecode interpreter
- even if the patented code is used.

-2008-09-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/base/rules.mk: Add conditional source to BASE_SRC, for `make
- multi' on Mac OS X. If the macro $(ftmac_c) is defined,
- $(BASE_DIR)/$(ftmac_c) is added to BASE_SRC. In a normal build, the
- lack of ftmac.c in BASE_SRC is not serious because ftbase.c includes
- ftmac.c.
- * builds/unix/unix-def.in: Add a macro definition of $(ftmac_c).
- * builds/unix/configure.raw: Add procedure to set up appropriate
- value of $(ftmac_c) with the consideration of the availability of
- Carbon framework.

- jam.
-
-2008-09-20 Werner Lemberg <wl@gnu.org>

-
- * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Fix double free bug in
- sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support code.
- `open_face_from_buffer' frees the passed buffer if it cannot open a
- face from the buffer, so the caller must not free it.
-
-2008-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Add initial support
- for sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font.
- (ft_lookup_PS_in_sfnt): New function to look up `TYP1' or `CID '
- table in sfnt table directory. It is used before loading TrueType
- font driver.
-
- * docs/CHANGES: Add note about the current status of sfnt-wrapped
- Type1 and sfnt-wrapped CID-keyed font support.
-
-2008-09-18 Werner Lemberg <wl@gnu.org>
-
- * src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for
- orthogonality (ft_free and ft_sfree could belong to different memory
- pools). This fixes Savannah bug #24297.
-
-2008-09-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined

-
-2008-09-15 Werner Lemberg <wl@gnu.org>
-
- * src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index'
- and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to
- prevent unconditional definition. This fixes Savannah bug #24241.
-
- * src/psnames/pstables.h: Regenerated.
-
-2008-09-13 Werner Lemberg <wl@gnu.org>
-
- * autogen.sh, builds/unix/configure.raw,
- include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor
- beautifying.
-
- * include/freetype/ftadvanc.h, include/freetype/ftgasp.h,

-
- * builds/unix/ftconfig.in: Duplicate the cpp computation of
- FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.
- (FT_USE_AUTOCONF_SIZEOF_TYPES): New macro. If defined, the cpp
- computation is disabled and the statically configured sizes are
- used. This fixes Savannah bug #21250.
-
- * builds/unix/configure.raw: Add the checks to compare the cpp
- computation results of the bit length of int and long versus the
- sizes detected by running `configure'. If the results are
- different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the
- results.
- New option --{enable|disable}-biarch-config is added to define or
- undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.
-
-2008-09-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or
- ApplicationService framework is missing. Although this value is not
- used in building of FreeType2, it is written in `freetype2.pc' and
- `freetype-config'.
-
-2008-09-01 david turner <david@freetype.org>
-
- * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap
- index to mean `use default cached FT_Face's charmap'. This fixes
- Savannah bug #22625.
- * include/freetype/ftcache.h: Document it.
-
-
- Make FT_MulFix an inlined function. This is done to speed up
- FreeType a little (on x86 3% when loading+hinting, 10% when
- rendering, ARM savings are more important though). Disable this by
- undefining FT_CONFIG_OPTION_INLINE_MULFIX.
-
- Use of assembler code can now be controlled with
- FT_CONFIG_OPTION_NO_ASSEMBLER.
-
- * include/freetype/config/ftconfig.h, builds/unix/ftconfig.in

- which is defined to the platform-specific assembler implementation
- of FT_MulFix.
- [FT_CONFIG_OPTION_INLINE_MULFIX && FT_MULFIX_ASSEMBLER]
- (FT_MULFIX_INLINED): New macro.
-
- * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_NO_ASSEMBLER,
- FT_CONFIG_OPTION_INLINE_MULFIX): New macros.
-
- * include/freetype/freetype.h: Updated to handle FT_MULFIX_INLINED.
-
- * src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and
- FT_MULFIX_INLINED.
-
-
- Add a new header named FT_ADVANCES_H declaring some new APIs to
- extract the advances of one or more glyphs without necessarily
- loading their outlines. Also provide `fast loaders' for the
- TrueType, Type1, and CFF font drivers (more to come later).
-
- * src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files.

- compare_to_minimum_version, check_tool_version): New auxiliary
- functions.
-
- * README.CVS: Document it.
-
-2008-08-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/sfnt/sfobjs.c (sfnt_open_font): Use TTAG_OTTO defined in

-
-2008-08-28 Werner Lemberg <wl@gnu.org>
-
- * src/type1/t1load.c (parse_encoding): Protect against infinite
- loop. This fixes Savannah bug #24150 (where a patch has been posted
- too).
-
-2008-08-23 Werner Lemberg <wl@gnu.org>
-
- * src/type/t1afm.c (compare_kern_pairs), src/pxaux/afmparse.c
- (afm_compare_kern_pairs): Fix comparison. This fixes Savannah bug
- #24119.
-
-2008-08-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,
- even if passed library or arguments are invalid. This fixes a bug
- that an uninitialized stream is freed when an invalid library handle
- is passed. Originally proposed by Mike Fabian, 2008/08/18 on
- freetype-devel.
- (FT_Open_Face): Ditto (stream).
- (load_face_in_embedded_rfork): Ditto (stream2).
-
-2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/base/ftmac.c: Add a fallback to guess the availability of the
- `ResourceIndex' type. It is used when built without configure
- (e.g., a build with Jam).
- * builds/mac/ftmac.c: Ditto.
- * builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0
- explicitly, even if `ResourceIndex' is unavailable.
-
-2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * builds/unix/configure.raw: In checking of Mac OS X features,
- all-in-one header file `Carbon.h' is replaced by the minimum
- header file `CoreServices.h', similar to current src/base/ftmac.c.
-
-2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of
- sub-header when its code_count is 0. Many Japanese Dynalab fonts
- include such an empty sub-header (code_count == 0, first_code == 0
- delta == 0, but offset != 0) as the second sub-header in SJIS cmap.
-
-2008-08-04 Werner Lemberg <wl@gnu.org>
-
- * src/type1/t1tokens.h: Handle `ForceBold' keyword. This fixes
- Savannah bug #23995.
-
- * src/cid/cidload.c (parse_expansion_factor): New callback function.
- (cid_field_records): Use it for `ExpansionFactor'.
- * src/cod/cidtoken.h: Handle `ForceBold' keyword.

-
-2008-08-04 Bram Tassyns <bramt@enfocus.be>
-
- * src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which
- resulted in incorrect scaling. This fixes Savannah bug #23973.
-
-2008-08-04 Werner Lemberg <wl@gnu.org>

-
- * src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and
- adjust table count.
- Add more trace messages.
- (tt_face_load_font_dir): Updated.
-
-2008-07-30 Werner Lemberg <wl@gnu.org>
-
- * src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
- assume that the first argument on the stack is the bottom-most
- element. Two reasons:
-
- o According to people from Adobe it is missing in the Type 2
- specification that pushing of additional, superfluous arguments
- on the stack is prohibited.
-
- o Acroread in general handles fonts differently, namely by popping
- the number of arguments needed for a particular operand (as a PS
- interpreter would do). In case of buggy fonts this causes a
- different interpretation which of the elements on the stack are
- superfluous and which not.
-
- Since there are CFF subfonts (embedded in PDFs) which rely on
- Acroread's behaviour, FreeType now does the same.
-
-2008-07-27 Werner Lemberg <wl@gnu.org>
-
- Add extra mappings for `Tcommaaccent' and `tcommaaccent'. This
- fixes Savannah bug #23940.
-
- * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...
- (EXTRA_GLYPH_LIST_SIZE): This.
- Increase by 2.

- * src/cff/cffgload.c (cff_decoder_prepare,
- cff_decoder_parse_charstrings): Improve debug output.
-
-2008-07-22 Martin McBride <mmcbride@emtex.com>
-
- * src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,
- tt_cmap4_char_map_binary): Handle fonts which treat the last segment
- specially. According to the specification, such fonts would be
- invalid but acroread accepts them.
-
-2008-07-16 Jon Foster <Jon.Foster@cabot.co.uk>
-
- * src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.

-2008-07-09 Werner Lemberg <wl@gnu.org>
-
- * src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts
- where num_locations < num_glyphs. Problem reported by Ding Li.
-
-2008-07-05 Werner Lemberg <wl@gnu.org>
-
- Since FreeType uses `$(value ...)', we now need GNU make 3.80 or
- newer. This fixes Savannah bug #23648.
-
- * configure: zsh doesn't like ${1+"$@"}.
- Update needed GNU make version.
- * builds/toplevel.mk: Check for `$(eval ...)'.
- * docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document
- it.
-
-2008-07-04 Werner Lemberg <wl@gnu.org>
-
- * src/raster/ftraster.c (Draw_Sweep): If span is smaller than one
- pixel, only check for dropouts if neither start nor end point lies
- on a pixel center. This fixes Savannah bug #23762.
-
-2008-06-29 Werner Lemberg <wl@gnu.org>
-

-2008-06-28 Werner Lemberg <wl@gnu.org>
-
- * src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...
- * src/ftcalc.c: Here. This fixes Savannah bug #23729.
-
-2008-06-27 Werner Lemberg <wl@gnu.org>
-
- * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
- Horizontal_Gray_Sweep_Drop): Test for intersections which
- degenerate to a single point can be ignored; this has been confirmed
- by Greg Hitchcock from Microsoft. (This was commented out code.)
-
-2008-06-26 Werner Lemberg <wl@gnu.org>
-
- Improve navigation in API reference.
-
- * src/tools/docmaker/tohtml.py (html_header_3): Renamed to...

-
- Convert ~ to non-breakable space.
-
- * src/tools/docmaker/tohtml.py (make_html_para): Implement it.
- Update header files accordingly.
-
-2008-06-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * builds/unix/configure.raw: Check type `ResourceIndex' explicitly
- and define HAVE_TYPE_RESOURCE_INDEX if it is defined. Mac OS X 10.5
- bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
- ResourceIndex type definition. The macro does not inform the type
- availability.
- * src/base/ftmac.c: More parentheses are inserted to clarify the
- conditionals to disable legacy APIs in `10.5 and later' cases. If
- HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.
-
-2008-06-24 Werner Lemberg <wl@gnu.org>
-
- * src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
- mode.
-
- * src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
- Draw_Sweep): No-dropout mode is value 2, not value 0.
- (Draw_Sweep): Really skip dropout handling for no-dropout mode.
-
-2008-06-24 Werner Lemberg <wl@gnu.org>
-
- * src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
- if it consists of one point only. Based on a patch from Savannah
- bug #23683 (from John Tytgat).
-
-2008-06-22 Werner Lemberg <wl@gnu.org>
-
- * src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
- with IS_HINTED.
-
- * docs/CHANGES: Updated.
-
-2008-06-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
- but LDFLAGS does not, import it to LDFLAGS. The option is used to
- specify non-default SDK on Mac OS X (e.g., universal binary SDK for
- Mac OS X 10.4 on PowerPC platform). Although Apple TechNote 2137
- recommends to add the option only to CFLAGS, LDFLAGS should include
- it because libfreetype.la is built with -no-undefined. This fixes a
- bug reported by Ryan Schmidt in MacPorts,
- http://trac.macports.org/ticket/15331.
-
-2008-06-21 Werner Lemberg <wl@gnu.org>
-
- Enable access to the various dropout rules of the B&W rasterizer.

- FT_OUTLINE_EXCLUDE_STUBS): New flags for for FT_Outline.
-
- * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
- Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the

- seems to fix Savannah bugs #20973 and (at least partially) #23310.
-
-2008-05-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid

- proposed by an anonymous reporter of Savannah bug #23204.
-
-2008-05-18 Werner Lemberg <wl@gnu.org>
-
- * src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
- correction for pixel boundary. Without this patch, the effect can
- be cumulative under certain circumstances, making glyphs taller and
- taller after each call. This fixes Savannah bug #19976.
-
-2008-05-18 Werner Lemberg <wl@gnu.org>
-
- * src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.

-2008-05-15 Werner Lemberg <wl@gnu.org>
-
- * src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
- which contains a single but empty entry. This is technically
- invalid (since it must end with `return'), but...
-
- Reported by Martin McBride.

-
-2008-05-03 Werner Lemberg <wl@gnu.org>
-

- * builds/symbian/*: New files.
-
-2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
- synthesis. For any face of a specified FOND, always the name for
- the first face was used. Except of a FOND that refers multiple
- Type1 font files, wrong synthesized font names are not used at all,
- so this is an invisible bug. A few limit checks are added too.
-
- * builds/mac/ftmac.c: Ditto.
-
-2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * builds/unix/configure.raw: Split compiler option to link Carbon
- frameworks to one option for CoreServices framework and another
- option for ApplicationServices framework. The split options can be
- managed by GNU libtool to avoid unrequired duplication when FreeType
- is linked with other applications. Suggested by Daniel Macks,
- Savannah bug #22366.
-
-2008-02-18 Victor Stinner <victor.stinner@haypocalc.com>

-
-2008-02-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
- handle by its value instead of ResError(), fix provided by Deron
- Kazmaier. According to the Resource Manager Reference,
- GetResource(), Get1Resource(), GetNamedResource(),
- Get1NamedResource() and RGetResource() set noErr but return NULL
- handle when they can not find the requested resource. These
- functions never return undefined values, so it is sufficient to
- check if the handle is not NULL.
-
- * builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.
-
-2008-02-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other

- builds/mac/ftmac.c is never included in any configuration.
-
- * builds/unix/configure.raw: Print warning if configure is executed
- with options to specify Carbon functionalities explicitly.
-
- * docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not
- included automatically and manual replacement is required.
-
-2008-02-11 Werner Lemberg <wl@gnu.org>
-
- * builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk
- (dos_setup), builds/freetype.mk (clean_project_dos,

-
- * src/truetype/ttgload.c (load_truetype_glyph): Handle the case
- where the number of contours in a simple glyph is zero (and which
- does contain an entry in the `glyf' table). This fixes Savannah bug
- #21990.

- correctly.
-
-2007-12-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- Improvement of POSIX resource-fork accessor to load unsorted
- references in a resource. In HelveLTMM (resource-fork PostScript
- Type1 font bundled with Mac OS X since 10.3.x), the appearance order
- of PFB chunks is not sorted; sorting the chunks by reference IDs is
- required.
-
- * include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
- type to store a pair of reference ID and offset to the chunk.
-
- * src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to

-
- * src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
- division too early; otherwise the most significant digit(s) of the
- final result are lost as the value is truncated to an integer. This
- fixes Savannah bug #21794 (where the patch has been posted too).
-
-2007-12-06 Fix <4d876b82@gmail.com>
-
- Pass options from one configure script to another as-is (not
- expanded). This is needed for options like

-
-2007-12-06 Werner Lemberg <wl@gnu.org>

-2007-12-06 Werner Lemberg <wl@gnu.org>
-
- There exist CFFs which contain opcodes for the Type 1 operators
- `hsbw' and `closepath' which are both invalid in Type 2 charstrings.
- However, it doesn't harm to support them.

- * src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
- `cff_op_closepath.'
- (cff_argument_counts): Ditto.
-

-
- * src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to

- Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is
- not working since 2.3.5. In FT_Open_New(), if FT_New_Stream()
- cannot mmap() the specified file and cannot seek to head of the
- specified file, it returns NULL stream and FT_Open_New() returns the
- error immediately. On MacOS, most legacy MacOS fonts fall into such
- a scenario because their data forks are zero-sized and cannot be
- sought. To proceed to guessing of resource fork fonts, the
- functions for legacy MacOS font must properly handle the NULL stream
- returned by FT_New_Stream().
-
- * src/base/ftobjs.c (IsMacBinary): Return error
- FT_Err_Invalid_Stream_Operation immediately when NULL stream is
- passed.
- (FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
- to fallback. Originally, legacy MacOS font is tested in the cases
- of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
- or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
- .dfont header is combined). Now the case of
- FT_Err_Cannot_Open_Stream is included.
-
- * src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
- skip FT_Stream_Seek(), which seeks to the head of stream, and
- proceed to unit testing of raccess_guess_XXX(). FT_Stream_Seek()
- for a NULL stream causes a Bus error on Mac OS X.
- (raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
- immediately if passed stream is NULL.
- (raccess_guess_apple_single): Ditto.

-
- Fix for Carbon incompatibilities since Mac OS X 10.5,
- proposed by Sean McBride.
-
- * doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.
-
- * include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
- FT_GetFilePath_From_Mac_ATS_Name. Since Mac OS X 10.5, calling
- Carbon functions from a forked process is classified as unsafe
- by Apple. All Carbon-dependent functions should be deprecated.
-
- * src/base/ftmac.c: Use essential header files
- <CoreServices/CoreServices.h> and
- <ApplicationServices/ApplicationServices.h> instead of
- all-in-one header file <Carbon/Carbon.h>.
-
- Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
- genuine macro PATH_MAX.
-
- Add fallback macro for kATSOptionFlagsUnRestrictedScope which
- is not found in Mac OS X 10.0.
-
- Multi-character constants ('POST', 'sfnt' etc) are replaced by
- 64bit constants calculated by FT_MAKE_TAG() macro.
-
- For the index in the segment of resource fork, new portable
- type ResourceIndex is introduced for better compatibility.
- This type is since Mac OS X 10.5, so it is defined as short
- when built on older platforms.
-
- (FT_ATSFontGetFileReference): If build target is only the systems
- 10.5 and newer, it calls Apple genuine ATSFontGetFileReference().
-
- (FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
- and newer or 64bit platform, because legacy type FSSpec type is
- removed completely.
-
- (FT_New_Face_From_FSSpec): Ditto.
-
-2007-11-01 Werner Lemberg <wl@gnu.org>
-

-
-2007-10-21 Werner Lemberg <wl@gnu.org>
-
- * src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare

- 1.5.

- (WWS_SUBFAMILY).

-
- * docs/VERSION.DLL, docs/release, README, Jamfile (RefDoc):
- s/2.3.0/2.3.1/.
-
- * builds/unix/configure.raw (version_info): Set to 9:12:3.
-
-
- * src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
- (af_loader_load_g): Disable the warper (i.e., the light hinting
- improvements) to make a 2.3.1 bugfix release before introducing a
- new feature. This should give us more time to tune and improve the
- warper for the next release.

- * docs/CHANGES: Update accordingly.
-
-2007-01-25 David Turner <david@freetype.org>
-
- For light auto-hinting, improve glyph advance widths and resurrect

-
-2007-01-25 Werner Lemberg <wl@gnu.org>

- correctly in a sanity check. Since this function is only used to
- load local and global functions, any charstring that called the last
- local/global function would fail otherwise. This fixes Savannah bug
- #18867.
-
- * docs/CHANGES: Document it.
-
-2007-01-23 David Turner <david@freetype.org>

- large Asian CFF fonts.
-
- * src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
- which happens when FT_Done_Library is called with still opened
