+ [autofit] Add more Indic scripts with hanging baseline.
+
+ * src/autofit/afindic.c (af_indic_uniranges): Tibetan, Limbu,
+ Sundanese, Meetei Mayak, Syloti Nagri and Sharada scripts are
+ added.
+
+2011-04-21 Behdad Esfahbod <behdad@behdad.org>
+
+ Always ignore global advance.
+
+ This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant,
+ deprecated, and ignored. The new behavior is what every major user
+ of FreeType has been requesting. Global advance is broken in many
+ CJK fonts. Just ignoring it by default makes most sense.

+
+ [autofit] Blur CJK stems if too many to preserve their gaps.
+
+ When there are too many stems to preserve their gaps in the
+ rasterization of CJK Ideographs at a low resolution, blur the
+ stems instead of showing clumped stems. See
+ http://lists.gnu.org/archive/html/freetype-devel/2011-02/msg00011.html
+ http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00046.html
+ for details.
+
+ * src/autofit/afcjk.c (af_cjk_hint_edges): Store the position of
+ the previous stem by `has_last_stem' and `last_stem_pos', and skip
+ a stem if the current and previous stem are too near to preserve
+ the gap.
+
+2011-04-18 Werner Lemberg <wl@gnu.org>
+
+ Integrate autofitter debugging stuff.
+
+ * devel/ftoption.h, include/freetype/config/ftoption.h
+ (FT_DEBUG_AUTOFIT): New macro.
+
+ * include/freetype/internal/fttrace.h: Add trace components for
+ autofitter.
+
+ * src/autofit/aftypes.h (AF_LOG): Removed.
+ (_af_debug): Removed.
+
+ * src/autofit/*: s/AF_DEBUG/FT_DEBUG_AUTOFIT/.

+
+ Fix Savannah bug #33047.
+
+ Patch submitted by anonymous reporter.

+ difference.
+
+2011-04-11 Kan-Ru Chen <kanru@kanru.info>
+
+ Fix reading of signed integers from files on 64bit platforms.
+
+ Previously, signed integers were converted to unsigned integers, but
+ this can fail because of sign extension. For example, 0xa344a1eb
+ becomes 0xffffffffa344a1eb.
+
+ We now do the reverse which is always correct because the integer
+ size is the same during the cast from unsigned to signed.
+
+ * include/freetype/internal/ftstream.h, src/base/ftstream.c
+ (FT_Stream_Get*): Replace with...
+ (FT_Stream_GetU*): Functions which read unsigned integers.
+ Update all macros accordingly.
+

+
+2011-04-07 Werner Lemberg <wl@gnu.org>

+
+2011-03-07 Alexei Podtelezhnikov <apodtele@gmail.com>

+ Quick fix for Savannah bug #32671.
+
+ This isn't the optimal solution yet, but it restores the previous

+
+ * src/smooth/ftgrays.c (gray_render_conic): Do more splitting.
+
+2011-03-06 Werner Lemberg <wl@gnu.org>
+

+ ignoring CFF-based OTFs.
+
+2011-02-27 Werner Lemberg <wl@gnu.org>
+
+ Add AF_CONFIG_OPTION_USE_WARPER to control the autofit warper.
+
+ * devel/ftoption.h, include/freetype/config/ftoption.h

+
+2011-02-24 Werner Lemberg <wl@gnu.org>
+

+
+ [autofit] Comment out unused code.

+
+ http://lists.gnu.org/archive/html/freetype/2011-01/msg00023.html
+
+ * src/cache/ftccache.c (FTC_Cache_RemoveFaceID): Check the node
+ buckets[cache->p + cache->mask] too.
+
+2011-02-19 Kevin Kofler <kevin.kofler@chello.at>
+
+ Fall back to autohinting if a TTF/OTF doesn't contain any bytecode.
+ This is Savannah patch #7471.

+
+2011-02-19 John Tytgat <John.Tytgat@esko.com>

+
+2011-02-13 Bradley Grainger <bgrainger@logos.com>
+
+ Add inline assembly version of FT_MulFix for MSVC.
+
+ * include/freetype/config/ftconfig.h: Ported the FT_MulFix_i386
+ function from GNU inline assembly syntax (see #ifdef __GNUC__ block
+ above) to MASM syntax for Microsoft Visual C++.
+
+2011-02-13 Bradley Grainger <bgrainger@logos.com>
+
+ Add project and solution files in Visual Studio 2010 format.
+

+
+2011-02-01 Werner Lemberg <wl@gnu.org>

+
+2011-02-01 Werner Lemberg <wl@gnu.org>
+
+ [cff] Ignore unknown operators in charstrings.
+ Patch suggested by Miles.Lau <sunliang_liu@foxitsoftware.com>.
+
+ * src/cff/cffgload.c (cff_decoder_parse_charstrings): Emit tracing
+ message for unknown operators and continue instead of exiting with a
+ syntax error.
+
+2011-02-01 Werner Lemberg <wl@gnu.org>
+
+ [truetype] FT_LOAD_PEDANTIC now affects `prep' and `fpgm' also.
+
+ * src/truetype/ttgload.c (tt_loader_init): Handle
+ `FT_LOAD_PEDANTIC'.
+ * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep,
+ tt_size_init_bytecode, tt_size_ready_bytecode): New argument to
+ handle pedantic mode.
+ * src/truetype/ttobjs.h: Updated.
+
+2011-01-31 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Protect jump instructions against endless loops.
+
+ * src/truetype/interp.c (DO_JROT, DO_JMPR, DO_JROF): Exit with error
+ if offset is zero.
+
+2011-01-31 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Improve handling of invalid references.
+
+ * src/truetype/interp.c: Set even more TT_Err_Invalid_Reference
+ error codes only if pedantic hinting is active. At the same time,
+ try to provide sane values which hopefully allow useful
+ continuation. Exception to this is CALL and LOOPCALL – due to
+ possible stack corruption it is necessary to bail out.
+
+2011-01-31 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Improve handling of stack underflow.
+
+ * src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP,
+ Ins_DELTAC): Exit with error only if `pedantic_hinting' is set.
+ Otherwise, try to do something sane.
+
+2011-01-30 Werner Lemberg <wl@gnu.org>
+
+ * src/sfnt/ttmtx.c (tt_face_load_hmtx): Fix tracing message.
+
+2011-01-30 LIU Sun-Liang <sunliang_liu@foxitsoftware.com>
+
+ [truetype]: Fix behaviour of MIAP for invalid arguments.
+
+ * src/truetype/ttinterp.c (Ins_MIAP): Set reference points even in
+ case of error.
+
+2011-01-18 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix handling of MIRP instruction.
+
+ Thanks to Greg Hitchcock who explained the issue.
+
+ * src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with
+ `>' since the description in the specification is incorrect.
+ This fixes, for example, glyph `two' in font `Helvetica Neue LT Com
+ 65 medium' at 15ppem.
+
+2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ Fix ARM assembly code in include/freetype/config/ftconfig.h.
+
+ * include/freetype/config/ftconfig.h (FT_MulFix_arm):
+ Copy the maintained code from builds/unix/ftconfig.in.
+ Old GNU binutils could not accept the reduced syntax
+ `orr %0, %2, lsl #16'. Un-omitted syntax like RVCT,
+ `orr %0, %0, %2, lsl #16' is better. Reported by
+ Johnson Y. Yan. The bug report by Qt developers is
+ considered too.
+
+ http://bugreports.qt.nokia.com/browse/QTBUG-6521
+
+2011-01-15 Werner Lemberg <wl@gnu.org>
+
+ [raster] Make bbox handling the same as with Microsoft's rasterizer.
+
+ Right before B/W rasterizing, the bbox gets simply rounded to
+ integers. This fixes, for example, glyph `three' in font `Helvetica
+ Neue LT Com 65 Medium' at 11ppem.
+
+ Thanks to Greg Hitchcock who explained this behaviour.
+
+ * src/raster/ftrend1.c (ft_raster1_render): Implement it.
+
+2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS.
+
+ * builds/unix/configure.raw: Consider recent gcc-standard
+ flags to specify architecture in CFLAGS & LDFLAGS
+ harmonization. Requested by Savannah bug #32114, to
+ support multilib feature of BuildRoot SDK correctly.
+
+2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer.
+
+ * builds/unix/configure.raw: Some important options that
+ included in CFLAGS but not in LDFLAGS are copied to
+ LDFLAGS, but the last option in CFLAGS was not checked.
+
+2011-01-13 Werner Lemberg <wl@gnu.org>
+
+ [raster] Add undocumented drop-out rule to the other bbox side also.
+
+ * src/raster/ftraster.c (Vertical_Sweep_Drop,
+ Horizontal_Sweep_Drop): Implement it.
+
+2011-01-13 Werner Lemberg <wl@gnu.org>
+
+ [raster] Reduce jitter value.
+
+ This catches a rendering problem with glyph `x' from Tahoma at
+ 10ppem. It seems that the increase of the precision in the change
+ from 2009-06-11 makes a larger jitter value unnecessary.
+
+ * src/raster/ftraster.c (Set_High_Precision): Implement it.
+
+2011-01-13 Werner Lemberg <wl@gnu.org>
+
+ [raster] Handle drop-outs at glyph borders according to Microsoft.
+
+ If a drop-out rule would switch on a pixel outside of the glyph's
+ bounding box, use the right (or top) pixel instead. This is an
+ undocumented feature, but some fonts like `Helvetica Neue LT Com 65
+ Medium' heavily rely on it.
+
+ Thanks to Greg Hitchcock who explained this behaviour.
+
+ * src/raster/ftraster.c (Vertical_Sweep_Drop,
+ Horizontal_Sweep_Drop): Implement it.
+
+2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ [cache] Fix Savannah bug #31923, patch drafted by Harsha.
+
+ When a node comparator changes the cached nodes during the
+ search of a node matching with queried properties, the
+ pointers obtained before the function should be updated to
+ prevent the dereference to freed or reallocated nodes.
+ To minimize the rescan of the linked list, the update is
+ executed when the comparator notifies the change of cached
+ nodes. This change depends previous change:
+ 38b272ffbbdaae276d636aec4ef84af407d16181
+
+ * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the
+ top node if the cached nodes are changed.
+ * src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.
+
+2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ [cache] Notice if a cache query induced the node list change.
+
+ Some node comparators (comparing the cache node contents and the
+ properties specified by the query) can flush the cache node to
+ prevent the cache inflation. The change may invalidate the pointers
+ to the node obtained before the node comparison, so it should be
+ noticed to the caller. The problem caused by the cache node
+ changing is reported by Harsha, see Savannah bug #31923.
+
+ * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument
+ `FT_Bool* list_changed' to indicate the change of the cached nodes
+ to the caller.
+ (FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by
+ `_list_changed'.
+ (FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
+ and update it when `FTC_Manager_FlushN' flushes any nodes.
+
+ * src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new
+ FTC_Node_CompareFunc type.
+ (ftc_gnode_compare): Ditto.
+
+ * src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use
+ TRUE/FALSE macros.
+ (ftc_basic_gnode_compare_faceid): New argument `FT_Bool*
+ list_changed' to indicate the change of the cache nodes (anyway, it
+ is always FALSE).
+
+ * src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use
+ TRUE/FALSE macros.
+ (ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to
+ indicate the change of the cache nodes (anyway, it is always FALSE).
+ (ftc_cmap_node_remove_faceid): Ditto.
+
+ * src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to
+ `FTC_CACHE_TRYLOOP_END', because the result is not needed.
+ (FTC_Cache_Lookup): Watch the change of the cache nodes by
+ `list_changed'.
+ (FTC_Cache_RemoveFaceID): Ditto.
+
+ * src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use
+ TRUE/FALSE macros.
+ (ftc_gnode_compare): New argument `FT_Bool* list_changed' to
+ indicate the change of the cache nodes (anyway, it is always FALSE).
+ (FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be
+ passed to `ftc_gnode_compare'.
+ * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
+
+ * src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*
+ list_changed' to indicate the change of the cache nodes, anyway. It
+ is updated by `FTC_CACHE_TRYLOOP'.
+ (FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be
+ passed to `ftc_snode_compare'.
+ * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
+
+2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ [cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'.
+
+ * src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd
+ argument `FTC_Cache cache' to fit FTC_Node_CompareFunc
+ prototype.
+ * src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,
+ `cache' is not used by its child `ftc_gnode_compare'.
+
+2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ [cache] Deduplicate the code to get the top node by a hash.
+
+ There are several duplicated code fragments getting the top node
+ from a cache by a given hash, like:
+
+ idx = hash & cache->mask;
+ if ( idx < cache->p )
+ idx = hash & ( cache->mask * 2 + 1 );
+ pnode = cache->buckets + idx;
+
+ To remove duplication, a cpp-macro to do same work
+ `FTC_NODE__TOP_FOR_HASH' is introduced. For non-inlined
+ configuration, non-`ftc_get_top_node_for_hash' is also introduced.
+
+ * src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare
+ and implement inlined version.
+ (FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'.
+ * src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined
+ version.
+ (ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'.
+ (ftc_node_hash_link): Ditto.
+ (FTC_Cache_Lookup): Ditto.
+
+2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ [cache] inline-specific functions are conditionalized.
+
+ * src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for
+ inlined configuration. This function is a thin wrapper of
+ `ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see
+ `nodecmp' argument). Under non-inlined configuration,
+ `ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via
+ `FTC_Cache->clazz.node_compare'.
+
+ * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
+ * src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for
+ `ftc_snode_compare'.
+ * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
+
+2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ [cache] Correct a type mismatch under non-inlined config.
+
+ * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup'
+ takes the node via a pointer `FTC_Node*', differently from cpp-macro
+ `FTC_CACHE_LOOKUP_CMP'.
+
+2011-01-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ Update Jamfile to include Bzip2 support.
+
+ * Jamfile: Include src/bzip2 to project.
+ Comments for lzw, gzip, bzip2 are changed to clarify that
+ they are for compressed PCF fonts, not others.
+ (e.g. compressed BDF fonts are not supported yet)
+
+2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ Update Symbian project files to include Bzip2 support.
+
+ Currently, it provides `FT_Stream_OpenBzip2' that returns
+ unimplemented error always, to prevent unresolved symbol
+ error for the applications designed for Unix systems.
+
+ * builds/symbian/bld.inf: Include ftbzip2.h.
+ * builds/symbian/freetype.mmp: Include ftbzip2.c.
+
+2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ Update classic MacOS makefiles to include Bzip2 support.
+
+ Currently, it provides `FT_Stream_OpenBzip2' that returns
+ unimplemented error always, to prevent unresolved symbol
+ error for the applications designed for Unix systems.
+
+ * builds/mac/FreeType.m68k_cfm.make.txt: Include ftbzip2.c.o.
+ * builds/mac/FreeType.m68k_far.make.txt: Ditto.
+ * builds/mac/FreeType.ppc_carbon.make.txt: Include ftbzip2.c.x.
+ * builds/mac/FreeType.ppc_classic.make.txt: Ditto.
+
+2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ Update Amiga makefiles to include Bzip2 support.
+
+ Currently, it provides `FT_Stream_OpenBzip2' that returns

+ error for the applications designed for Unix systems.
+
+ * builds/amiga/makefile: Include bzip2.ppc.o built from ftbzip2.c.
+ * builds/amiga/makefile.os4: Include bzip2.o built from ftbzip2.c.
+ * builds/amiga/smakefile: Ditto.
+
+2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ Update pkg-config tools to reflect Bzip2 support.
+

+
+ Apply Savannah patch #7422.
+
+ If we encounter a space in a string then the sbit buffer is NULL,
+ height and width are 0s. So the check in ftc_snode_compare will
+ always pass for spaces (comparision with 255). Here the comments
+ above the condition are proper but the implementation is not. When
+ we create an snode I think it is the proper way to initialize the
+ width to 255 and then put a check for being equal to 255 in snode
+ compare function.

+
+ On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)

+ [raccess] Skip unrequired resource access rules by Darwin VFS.
+
+ When a resource fork access rule by Darwin VFS could open the

+ * src/base/ftobjs.c (load_face_in_embedded_rfork):
+ When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it
+ means that the file is possible to be `fopen'-ed but zero-sized.
+ Also there is a case that the resource fork is not zero-sized,
+ but no supported font exists in it. If a rule by Darwin VFS
+ falls into such cases, there is no need to try other Darwin VFS
+ rules anymore. Such cases are marked by vfs_rfork_has_no_font.
+ If it is TRUE, the Darwin VFS rules are skipped.

+ 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

+ To use this function in ftobjs.c etc but it should be inlined,
+ it is exposed by ftbase.h.

+ [sfnt] Prevent overrunning in `post' table parser.
+ See Savannah bug #31040.

+ (load_format_20): Stop the parsing when we reached at the limit of
+ `post' table. If more glyph names are required, they are filled by
+ NULL names.

+
+ * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate
+ FT_GlyphZoneRec size->twilight to be freed. If duplicated,

+ (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if
+ an error occurs in the bytecode interpretation. The interpretation
+ of invalid bytecode may break the function definitions and referring
+ them in later interpretation is danger. By unsetting these flags,
+ `fpgm' and `prep' tables are executed again in next interpretation.

+
+2010-05-10 Ken Sharp <ken.sharp@artifex.com>
+
+ Fix Savannah bug #29846.
+
+ Previously we discovered fonts which used `setcurrentpoint' to set
+ the initial point of a contour to 0,0. 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.
