1.52 +
1.53 + Really fix Savannah bug #28678 (part 2).
1.54 +
1.55 + Since we consider `sbw' for the horizontal direction only, we still have
1.56 + to synthesize vertical metrics if the user wants to use the vertical
1.57 + writing direction.
1.58 +
1.59 + * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
1.60 + (cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph):
1.61 + Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is
1.62 + set.
1.63 +
1.64 +2010-02-10 Ken Sharp <ken.sharp@artifex.com>
1.65 +
1.66 + Really fix Savannah bug #28678 (part 1).
1.67 +
1.68 + After long discussion, we now consider the character width vector
1.69 + (wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
1.70 + direction only. For example, if you are using the horizontal
1.71 + writing direction, you get the horizontal and vertical components of
1.72 + the advance width for this direction. Note that OpenType and CFF fonts
1.73 + don't have such a vertical component; instead, the GPOS table can be
1.74 + used to generate two-dimensional advance widths (but this isn't
1.75 + handled by FreeType).
1.76 +
1.77 + * include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add
1.78 + `advance_v' field to hold the vertical component of the advance
1.79 + value.
1.80 +
1.81 + * src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c

1.147 +2010-01-11 Kwang Yul Seo <skyul@company100.net>
1.148 +
1.149 + Provide inline assembly code for RVCT compiler.
1.150 + This is Savannah patch #7059.
1.151 +
1.152 + * include/freetype/config/ftconfig.h (FT_MULFIX_ASSEMBLER,
1.153 + FT_MulFix_arm) [__CC_ARM || __ARM_CC]: Define.
1.154 +
1.155 +2010-01-08 Ken Sharp <ken.sharp@artifex.com>
1.156 +
1.157 + Fix Savannah bug #28521.
1.158 +
1.159 + Issue #28226 involved a work-around for a font which used the
1.160 + `setcurrentpoint' operator in an invalid way; this operator is only
1.161 + supposed to be used with the result of OtherSubrs, and the font used
1.162 + it directly. The supplied patch removed the block of code which
1.163 + checked this usage entirely.
1.164 +
1.165 + This turns out to be a Bad Thing. If `setcurrentpoint' is being
1.166 + used correctly it should reset the flex flag in the decoder. If we
1.167 + don't do this then the flag never gets reset and we omit any further
1.168 + contours from the glyph (at least until we close the path or
1.169 + similar).
1.170 +
1.171 + * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
1.172 + <op_setcurrentpoint>: Handle `flex_state' correctly.
1.173 +
1.174 +2010-01-05 Werner Lemberg <wl@gnu.org>
1.175 +
1.176 + Apply reports from clang static analyzer.
1.177 +
1.178 + * src/lzw/ftlzw.c (ft_lzw_file_init), src/base/ftstroke.c
1.179 + (FT_Stroker_ParseOutline), src/base/ftsynth.c
1.180 + (FT_GlyphSlot_Embolden): Remove dead code.
1.181 +
1.182 + * src/base/ftpatent.c (_tt_check_patents_in_table): Initialize
1.183 + `offset_i' and `length_i'.
1.184 +
1.185 +2010-01-05 Ralph Giles <giles@ghostscript.com>
1.186 +
1.187 + Enable the incremental font interface by default.
1.188 +
1.189 + Ghostscript requires the incremental font interface for handling
1.190 + some Postscript documents. It is moving to using FreeType as its
1.191 + primary renderer; supporting this in the default build makes it
1.192 + Ghostscript to be linked against the system FreeType when one is
1.193 + available.
1.194 +
1.195 + * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):
1.196 + Uncomment.
1.197 +
1.198 +2010-01-05 Werner Lemberg <wl@gnu.org>
1.199 +
1.200 + Fix Savannah bug #28395.
1.201 +
1.202 + * src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c
1.203 + (T1_Loada_Glyph): Don't check `num_glyphs' if incremental interface
1.204 + is used.
1.205 +
1.206 +2010-01-05 Ken Sharp <ken.sharp@artifex.com>
1.207 +
1.208 + Make Type 1 `seac' operator work with incremental interface.
1.209 + This fixes Savannah bug #28480.
1.210 +
1.211 + * src/psaux/t1decode.c (t1operator_seac): Don't check `glyph_names'
1.212 + if incremental interface is used.
1.213 +
1.214 +2010-01-04 Ken Sharp <ken.sharp@artifex.com>
1.215 +
1.216 + Make incremental interface work with TrueType fonts.
1.217 + This fixes Savannah bug #28478.
1.218 +
1.219 + * src/truetype/ttgload.c (load_truetype_glyph): Don't check
1.220 + `glyf_offset' if incremental interface is used.
1.221 +
1.222 +2009-12-31 Lars Abrahamsson <wonko@opera.com>
1.223 +
1.224 + Make compilation with FT_CONFIG_OPTION_PIC work again.
1.225 +
1.226 + * src/base/ftglyph.c (FT_Glyph_To_Bitmap) [FT_CONFIG_OPTION_PIC]:
1.227 + Declare `library' for FT_BITMAP_GLYPH_CLASS_GET.
1.228 +
1.229 + * src/base/ftinit.c (ft_destroy_default_module_classes,
1.230 + ft_create_default_module_classes): Use proper casts (needed for C++
1.231 + compilation).
1.232 +
1.233 + * src/sfnt/ttcmap.c (tt_cmap13_class_rec): Use FT_DEFINE_TT_CMAP.
1.234 +
1.235 +2009-12-22 Marc Kleine-Budde <mkl@pengutronix.de>
1.236 +
1.237 + Make freetype-config aware of $SYSROOT.
1.238 + This is Savannah patch #7040.
1.239 +
1.240 + * builds/unix/freetype-config.in: Decorate with ${SYSROOT} where
1.241 + appropriate.
1.242 +
1.243 +2009-12-20 Werner Lemberg <wl@gnu.org>
1.244 +
1.245 + Fix compiler warning.
1.246 + Reported by Sean.
1.247 +
1.248 + * src/base/ftdbgmem.c [!FT_DEBUG_MEMORY]: ANSI C doesn't like empty
1.249 + source files; however, some compilers warn about an unused variable
1.250 + declaration. This is now replaced with a typedef.
1.251 +
1.252 +2009-12-18 Werner Lemberg <wl@gnu.org>
1.253 +
1.254 + Fix Savannah bug #28320.
1.255 +
1.256 + There exist corrupt, subsetted fonts (embedded in PDF files) which
1.257 + contain a private dict that ends with an unterminated floating point
1.258 + number (no operator following). We now ignore this error (as
1.259 + acrobat does).
1.260 +
1.261 + * src/cff/cffparse.c (cff_parser_run): Don't emit a syntax error for
1.262 + unterminated floating point numbers.
1.263 +
1.264 +2009-12-16 Werner Lemberg <wl@gnu.org>
1.265 +
1.266 + Really fix compiler warnings.
1.267 + Reported by Sean.
1.268 +
1.269 + * src/truetype/ttgxvar.c (GX_PT_POINTS_ARE_WORDS,
1.270 + GX_PT_POINT_RUN_COUNT_MASK): Convert enum values to macros.
1.271 +
1.272 +2009-12-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.273 +
1.274 + Improve configure.raw to copy some options from CFLAGS to LDFLAGS.
1.275 + The linker of Mac OS X 10.6 is sensitive to the architecture. If
1.276 + the architectures are specified explicitly for the C compiler, the
1.277 + linker requires the architecture specifications too.
1.278 +
1.279 + * builds/unix/configure.raw: Replace `-isysroot' option parser by
1.280 + more generic argument parser.
1.281 +
1.282 +2009-12-15 Werner Lemberg <wl@gnu.org>
1.283 +
1.284 + Fix compiler warnings.
1.285 + Reported by Sean.
1.286 +
1.287 + * src/truetype/ttgxvar.c (ft_var_readpackeddeltas): Fix counter data
1.288 + type.
1.289 +
1.290 +2009-12-14 Ken Sharp <ken.sharp@artifex.com>
1.291 +
1.292 + Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
1.293 + This fixes Savannah bug #28226.
1.294 +
1.295 + At least two wild PostScript files of unknown provenance contain
1.296 + Type 1 fonts, apparently converted from TrueType fonts in earlier
1.297 + PDF versions of the files, which use the `setcurrentpoint' operator
1.298 + inappropriately.
1.299 +
1.300 + FreeType currently throws an error in this case, but Ghostscript and
1.301 + Adobe Distiller both accept the fonts and ignore the problem. This
1.302 + commit #ifdefs out the check so PostScript interpreters using
1.303 + FreeType can render these files.
1.304 +
1.305 + The specification says `setcurrentpoint' should only be used to set
1.306 + the point after a `Subr' call, but these fonts use it to set the
1.307 + initial point to (0,0). Unnecessarily so, as they correctly use an
1.308 + `hsbw' operation which implicitly sets the initial point.
1.309 +
1.310 + * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
1.311 + <op_setcurrentpoint>: Comment out code.
1.312 +
1.313 +2009-12-14 Bram Tassyns <bramt@enfocus.be>
1.314 +
1.315 + Fix parsing of /CIDFontVersion.
1.316 + This fixes Savannah bug #28287.
1.317 +
1.318 + * src/cid/cidtoken.h: `cid_version' in CID_FaceInfoRec (in
1.319 + t1tables.h) is of type FT_Fixed.
1.320 +
1.321 +2009-12-14 Werner Lemberg <wl@gnu.org>

1.338 + Better handling of start of `eexec' section.

1.627 + [BDF] Modify hash API to take size_t value instead of void *.
1.628 +
1.629 + The hash API in BDF driver is designed to be generic, it takes
1.630 + void * typed data. But BDF driver always gives an unsigned long
1.631 + integer (the index to a property). To reduce non-essential

1.633 + long, the hash API is changed to take size_t integer.
1.634 + The issue of incompatible cast between unsigned long and void*

1.681 +
1.682 + Improve vertical metrics calculation (Savannah bug #27364).
1.683 +
1.684 + The calculation of `vertBearingX' is not defined in the OTF font
1.685 + spec so FreeType does a `best effort' attempt. However, this value
1.686 + is defined in the PDF and PostScript specs, and that algorithm is
1.687 + better than the one FreeType currently uses:
1.688 +
1.689 + FreeType: Use the middle of the bounding box as the X coordinate
1.690 + of the vertical origin.
1.691 +
1.692 + Adobe PDF spec: Use the middle of the horizontal advance vector as
1.693 + the X coordinate of the vertical origin.
1.694 +
1.695 + FreeType's algorithm goes wrong if you have a really small glyph
1.696 + (like the full-width, circle-like dot at the end of the sentence, as
1.697 + used in CJK scripts) with large bearings. With the FreeType
1.698 + algorithm this dot gets centered on the baseline; with the PDF
1.699 + algorithm it gets the correct location (in the top right). Note
1.700 + that this is a serious issue, it's like printing the dot at the end
1.701 + of a Roman sentence at the center of the textline instead of on the
1.702 + baseline like it should. So i believe the PDF spec's algorithm
1.703 + should be used in FreeType as well.
1.704 +
1.705 + The `vertBearingY' value for such small glyphs is also very strange
1.706 + if no `vmtx' information is present, since the height of the bbox is
1.707 + not representable for the height of the glyph visually (the
1.708 + whitespace up to the baseline is part of the glyph). The fix also
1.709 + includes some code for a better estimate of `vertBearingY'.
1.710 +
1.711 + * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
1.712 + is now calculated as described by the Adobe PDF Spec. Estimate for
1.713 + `vertBearingY' now works better for small glyphs completely above or
1.714 + below the baseline into account.
1.715 +
1.716 + * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
1.717 + calculated as described by the Adobe PDF Spec. Vertical metrics
1.718 + information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
1.719 + was not defined.
1.720 +

1.722 + now calculated as described by the Adobe PDF Spec.

1.2105 + Previously, only integers have been used which can lead to serious

1.2107 +
1.2108 + However, fractional values are only used internally; after the

1.2112 + flag should be introduced, to be used in combination with
1.2113 + FT_LOAD_NO_SCALE, which indicates that font units are returned in

1.2219 +
1.2220 + Fix B/W rasterization of subglyphs with different drop-out modes.
1.2221 +
1.2222 + Normally, the SCANMODE instruction (if present) to set the drop-out
1.2223 + mode in a TrueType font is located in the `prep' table only and thus
1.2224 + valid for all glyphs. However, there are fonts like `pala.ttf'
1.2225 + which additionally contain this instruction in the hinting code of
1.2226 + some glyphs (but not all). As a result it can happen that a
1.2227 + composite glyph needs multiple drop-out modes for its subglyphs
1.2228 + since the rendering state gets reset for each subglyph.
1.2229 +
1.2230 + FreeType collects the hinted outlines from all subglyphs, then it
1.2231 + sends the data to the rasterizer. It also sends the drop-out mode
1.2232 + -- after hinting has been applied -- and here is the error: It sends
1.2233 + the drop-out mode of the last subglyph only; drop-out modes of all
1.2234 + other subglyphs are lost.
1.2235 +
1.2236 + This patch fixes the problem; it adds a second, alternative
1.2237 + mechanism to pass the drop-out mode: For each contour, the
1.2238 + rasterizer now checks the first `tags' array element. If bit 2 is
1.2239 + set, bits 5-7 contain the contour's drop-out mode, overriding the
1.2240 + global drop-out mode.
1.2241 +
1.2242 + * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.
1.2243 +
1.2244 + * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in
1.2245 + `tags[0]'.
1.2246 +
1.2247 + * src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):
1.2248 + Use bits 3-5 instead of 0-2.
1.2249 + (New_Profile): Set the drop-out mode in the profile's `flags' field.
1.2250 + (Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
1.2251 + necessary.
1.2252 + (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
1.2253 + Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out
1.2254 + mode.

1.2256 +2009-06-16 Werner Lemberg <wl@gnu.org>
1.2257 +
1.2258 + Improve scan conversion rules 4 and 6.
1.2259 +
1.2260 + Two new constraints are introduced to better identify a `stub' -- a
1.2261 + concept which is only vaguely described in the OpenType
1.2262 + specification. The old code was too rigorous and suppressed more
1.2263 + pixel than it should.
1.2264 +
1.2265 + . The intersection of the two profiles with the scanline is less
1.2266 + than a half pixel. Code related to this was already present in
1.2267 + the sources but has been commented out.
1.2268 +
1.2269 + . The endpoint of the original contour forming a profile has a
1.2270 + distance (`overshoot') less than half a pixel to the scanline.
1.2271 +
1.2272 + Note that the two additional conditions fix almost all differences
1.2273 + to the Windows rasterizer, but some problematic cases remain.
1.2274 +
1.2275 + * src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New
1.2276 + macros for the `flags' field in the `TProfile' structure.
1.2277 + (IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros.

1.3131 + * src/sfnt/rules.mk (SFNT_DRV_H): Add ttsbit0.c.
1.3132 +
1.3133 +2009-03-09 Alexey Kryukov <anagnost@yandex.ru>
1.3134 +
1.3135 + Fix handling of EBDT formats 8 and 9 (part 2).
1.3136 +
1.3137 + This patch fixes the following problems in ttsbit0.c:
1.3138 +
1.3139 + . Bitmaps for compound glyphs were never allocated.
1.3140 +
1.3141 + . `SBitDecoder' refused to load metrics if some other metrics have
1.3142 + already been loaded. This condition certainly makes no sense for
1.3143 + recursive calls, so I've just disabled it. Another possibility
1.3144 + would be resetting `decoder->metrics_loaded' to false before
1.3145 + loading each composite component. However, we must restore the
1.3146 + original metrics after finishing the recursion; otherwise we can
1.3147 + get a misaligned glyph.
1.3148 +
1.3149 + . `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',
1.3150 + causing some glyph components to be shifted too far to the right
1.3151 + (especially noticeable for small sizes).
1.3152 +
1.3153 + Note that support for grayscale bitmaps (not necessarily compound) is
1.3154 + completely broken in ttsbit0.c.
1.3155 +
1.3156 + * src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.
1.3157 + (tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case
1.3158 + of `h == height'.
1.3159 + (tt_sbit_decoder_load_compound): Reset metrics after loading
1.3160 + components.
1.3161 + Allocate bitmap.
1.3162 +
1.3163 +2009-03-09 Werner Lemberg <wl@gnu.org>
1.3164 +
1.3165 + * builds/unix/configure.raw (version_info): Set to 9:20:3.
1.3166 +
1.3167 +2009-03-03 David Turner <david@freetype.org>
1.3168 +
1.3169 + Protect SFNT kerning table parser against malformed tables.
1.3170 +
1.3171 + This closes Savannah BUG #25750.
1.3172 +
1.3173 + * src/sfnt/ttkern.c (tt_face_load_kern, tt_face_get_kerning): Fix a
1.3174 + bug where a malformed table would be successfully loaded but later

1.3187 + Remove ABI-breaking field in public PS_InfoFontRec definition.
1.3188 +
1.3189 + Instead, we define a new internal PS_FontExtraRec structure to

1.3226 +
1.3227 + The main cycle in `blit_sbit' makes too many iterations: it actually

1.3229 + target image.
1.3230 +

1.3538 + FT_USE_MODULE declares things as:
1.3539 +
1.3540 + extern const FT_Module_Class
1.3541 +
1.3542 + (or similar for C++). However, the actual types of the variables
1.3543 + being declared are often different, e.g., FT_Driver_ClassRec or
1.3544 + FT_Renderer_Class. (Some are, indeed, FT_Module_Class.)
1.3545 +
1.3546 + This works with most C compilers (since those structs begin with an
1.3547 + FT_Module_Class struct), but technically it's undefined behavior.
1.3548 +
1.3549 + To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
1.3550 + paragraph 2:
1.3551 +
1.3552 + All declarations that refer to the same object or function shall
1.3553 + have compatible type; otherwise, the behavior is undefined.
1.3554 +
1.3555 + (And they are not compatible types.)
1.3556 +
1.3557 + Most C compilers don't reject (or even detect!) code which has this
1.3558 + issue, but the GCC LTO development branch compiler does. (It
1.3559 + outputs the types of the objects while generating .o files, along
1.3560 + with a bunch of other information, then compares them when doing the
1.3561 + final link-time code generation pass.)

1.3616 +
1.3617 + Generalize the concept of `tricky' fonts by introducing
1.3618 + FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
1.3619 + engine is necessary for correct rendering.
1.3620 +
1.3621 + At the same time, slightly modify the behaviour of tricky fonts:
1.3622 + FT_LOAD_NO_HINTING is now ignored. To really force raw loading
1.3623 + of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
1.3624 + FT_LOAD_NO_AUTOHINT must be used.
1.3625 +
1.3626 + Finally, tricky TrueType fonts always use the bytecode interpreter
1.3627 + even if the patented code is used.

1.3927 + rule compiling ftmac.c separately is removed and the rule copying
1.3928 + ftbase.c from src/base/ftbase.c to builds/mac/ftbase.c is added.
1.3929 + * builds/mac/FreeType.m68k_cfm.make.txt: Ditto.

1.3934 +
1.3935 + * src/cff/cffgload.c (cff_slot_load): Map CID 0 to GID 0. This
1.3936 + fixes Savannah bug #24430.
1.3937 +
1.3938 +2008-10-02 Werner Lemberg <wl@gnu.org>
1.3939 +
1.3940 + * builds/freetype.mk (BASE_H): Rename to...
1.3941 + (INTERNAL_H): This.
1.3942 + (FREETYPE_H): Updated.

1.3951 +
1.3952 + * src/base/ftbase.h: New file to declare the private utility
1.3953 + functions shared by the sources of base modules. Currently,
1.3954 + `ft_lookup_PS_in_sfnt' and `open_face_from_buffer' are declared to
1.3955 + share between ftobjs.c and ftmac.c.
1.3956 +
1.3957 + * src/base/rule.mk: Add ftbase.h.
1.3958 +
1.3959 + * src/base/ftobjs.c: Include ftbase.h.
1.3960 + (memory_stream_close): Build on any platform when old MacOS font
1.3961 + support is enabled.
1.3962 + (new_memory_stream): Ditto.
1.3963 + (open_face_from_buffer): Build on any platform when old MacOS font
1.3964 + support is enabled. The counting of the face in a font file is
1.3965 + slightly different between Carbon-dependent parser and Carbon-free
1.3966 + parser. They are merged with the platform-specific conditional.
1.3967 + (ft_lookup_PS_in_sfnt): Ditto.
1.3968 +
1.3969 + * src/base/ftmac.c: Include ftbase.h.
1.3970 + (memory_stream_close): Removed.
1.3971 + (new_memory_stream): Ditto.
1.3972 + (open_face_from_buffer): Removed. Use the implementation in

1.3991 +
1.3992 + * src/base/rules.mk: Add conditional source to BASE_SRC, for `make
1.3993 + multi' on Mac OS X. If the macro $(ftmac_c) is defined,
1.3994 + $(BASE_DIR)/$(ftmac_c) is added to BASE_SRC. In a normal build, the
1.3995 + lack of ftmac.c in BASE_SRC is not serious because ftbase.c includes
1.3996 + ftmac.c.
1.3997 + * builds/unix/unix-def.in: Add a macro definition of $(ftmac_c).
1.3998 + * builds/unix/configure.raw: Add procedure to set up appropriate
1.3999 + value of $(ftmac_c) with the consideration of the availability of
1.4000 + Carbon framework.

1.4079 + * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Fix double free bug in
1.4080 + sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support code.
1.4081 + `open_face_from_buffer' frees the passed buffer if it cannot open a

1.4084 +2008-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.4085 +
1.4086 + * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Add initial support

1.4125 +
1.4126 +2008-09-13 Werner Lemberg <wl@gnu.org>
1.4127 +
1.4128 + * autogen.sh, builds/unix/configure.raw,

1.4146 + FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.
1.4147 + (FT_USE_AUTOCONF_SIZEOF_TYPES): New macro. If defined, the cpp
1.4148 + computation is disabled and the statically configured sizes are
1.4149 + used. This fixes Savannah bug #21250.
1.4150 +
1.4151 + * builds/unix/configure.raw: Add the checks to compare the cpp
1.4152 + computation results of the bit length of int and long versus the
1.4153 + sizes detected by running `configure'. If the results are
1.4154 + different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the

1.4160 +
1.4161 + * builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or

1.4171 + * include/freetype/ftcache.h: Document it.
1.4172 +
1.4173 +
1.4174 + Make FT_MulFix an inlined function. This is done to speed up
1.4175 + FreeType a little (on x86 3% when loading+hinting, 10% when

1.4177 + undefining FT_CONFIG_OPTION_INLINE_MULFIX.
1.4178 +
1.4179 + Use of assembler code can now be controlled with

1.4200 +
1.4201 +
1.4202 + Add a new header named FT_ADVANCES_H declaring some new APIs to

1.4214 + respectively.
1.4215 +
1.4216 + * src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC): Add

1.4241 +
1.4242 + Add checks for minimum version of the `autotools' stuff.
1.4243 +
1.4244 + * autogen.sh: Implement it.
1.4245 + (get_major_version, get_minor_version, get_patch_version,

1.4269 +
1.4270 + * src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,
1.4271 + even if passed library or arguments are invalid. This fixes a bug
1.4272 + that an uninitialized stream is freed when an invalid library handle
1.4273 + is passed. Originally proposed by Mike Fabian, 2008/08/18 on
1.4274 + freetype-devel.

1.4282 + (e.g., a build with Jam).
1.4283 + * builds/mac/ftmac.c: Ditto.
1.4284 + * builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0

1.4286 +
1.4287 +2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.4288 +
1.4289 + * builds/unix/configure.raw: In checking of Mac OS X features,

1.4294 +
1.4295 + * src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of
1.4296 + sub-header when its code_count is 0. Many Japanese Dynalab fonts
1.4297 + include such an empty sub-header (code_count == 0, first_code == 0
1.4298 + delta == 0, but offset != 0) as the second sub-header in SJIS cmap.
1.4299 +
1.4300 +2008-08-04 Werner Lemberg <wl@gnu.org>
1.4301 +
1.4302 + * src/type1/t1tokens.h: Handle `ForceBold' keyword. This fixes
1.4303 + Savannah bug #23995.
1.4304 +
1.4305 + * src/cid/cidload.c (parse_expansion_factor): New callback function.
1.4306 + (cid_field_records): Use it for `ExpansionFactor'.
1.4307 + * src/cod/cidtoken.h: Handle `ForceBold' keyword.
1.4308 + Don't handle `ExpansionFactor'.
1.4309 +
1.4310 +2008-08-04 Bram Tassyns <bramt@enfocus.be>
1.4311 +
1.4312 + * src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which
1.4313 + resulted in incorrect scaling. This fixes Savannah bug #23973.
1.4314 +
1.4315 +2008-08-04 Werner Lemberg <wl@gnu.org>
1.4316 +
1.4317 + Be more tolerant w.r.t. invalid entries in SFNT table directory.
1.4318 +
1.4319 + * src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and
1.4320 + adjust table count.
1.4321 + Add more trace messages.
1.4322 + (tt_face_load_font_dir): Updated.
1.4323 +
1.4324 +2008-07-30 Werner Lemberg <wl@gnu.org>
1.4325 +
1.4326 + * src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
1.4327 + assume that the first argument on the stack is the bottom-most
1.4328 + element. Two reasons:
1.4329 +
1.4330 + o According to people from Adobe it is missing in the Type 2
1.4331 + specification that pushing of additional, superfluous arguments
1.4332 + on the stack is prohibited.
1.4333 +
1.4334 + o Acroread in general handles fonts differently, namely by popping
1.4335 + the number of arguments needed for a particular operand (as a PS
1.4336 + interpreter would do). In case of buggy fonts this causes a
1.4337 + different interpretation which of the elements on the stack are
1.4338 + superfluous and which not.
1.4339 +
1.4340 + Since there are CFF subfonts (embedded in PDFs) which rely on
1.4341 + Acroread's behaviour, FreeType now does the same.
1.4342 +
1.4343 +2008-07-27 Werner Lemberg <wl@gnu.org>
1.4344 +
1.4345 + Add extra mappings for `Tcommaaccent' and `tcommaaccent'. This
1.4346 + fixes Savannah bug #23940.
1.4347 +
1.4348 + * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...
1.4349 + (EXTRA_GLYPH_LIST_SIZE): This.

1.4359 + Add two offsets.
1.4360 +
1.4361 + (ps_check_wgl_name, ps_check_wgl_unicode): Rename to...
1.4362 + (ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This.
1.4363 + Updated.
1.4364 + (ps_unicodes_init): Updated.
1.4365 +
1.4366 +2008-07-26 Werner Lemberg <wl@gnu.org>
1.4367 +
1.4368 + * src/cff/cffgload.c (cff_decoder_prepare,
1.4369 + cff_decoder_parse_charstrings): Improve debug output.
1.4370 +
1.4371 +2008-07-22 Martin McBride <mmcbride@emtex.com>
1.4372 +
1.4373 + * src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,
1.4374 + tt_cmap4_char_map_binary): Handle fonts which treat the last segment
1.4375 + specially. According to the specification, such fonts would be
1.4376 + invalid but acroread accepts them.
1.4377 +
1.4378 +2008-07-16 Jon Foster <Jon.Foster@cabot.co.uk>
1.4379 +
1.4380 + * src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.
1.4381 +
1.4382 + * src/base/ftcalc.c (FT_MulFix): Fix portability issue.
1.4383 +
1.4384 + * src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]:
1.4385 + Fix compiler warning.
1.4386 +
1.4387 +2008-07-16 Werner Lemberg <wl@gnu.org>
1.4388 +
1.4389 + Handle CID-keyed fonts wrapped in an SFNT (with cmaps) correctly.
1.4390 +
1.4391 + * src/cff/cffload.c (cff_font_load): Pass `pure_cff'.
1.4392 + Invert sids table only if `pure_cff' is set.
1.4393 + * src/cff/cffload.h: Udpated.
1.4394 +
1.4395 + * src/cff/cffobjs.c (cff_face_init): Updated.
1.4396 + Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set.
1.4397 +
1.4398 + * docs/CHANGES: Updated.
1.4399 +
1.4400 +2008-07-09 Werner Lemberg <wl@gnu.org>
1.4401 +
1.4402 + * src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts
1.4403 + where num_locations < num_glyphs. Problem reported by Ding Li.
1.4404 +
1.4405 +2008-07-05 Werner Lemberg <wl@gnu.org>
1.4406 +
1.4407 + Since FreeType uses `$(value ...)', we now need GNU make 3.80 or
1.4408 + newer. This fixes Savannah bug #23648.
1.4409 +
1.4410 + * configure: zsh doesn't like ${1+"$@"}.
1.4411 + Update needed GNU make version.
1.4412 + * builds/toplevel.mk: Check for `$(eval ...)'.
1.4413 + * docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document
1.4414 + it.
1.4415 +
1.4416 +2008-07-04 Werner Lemberg <wl@gnu.org>
1.4417 +
1.4418 + * src/raster/ftraster.c (Draw_Sweep): If span is smaller than one
1.4419 + pixel, only check for dropouts if neither start nor end point lies
1.4420 + on a pixel center. This fixes Savannah bug #23762.
1.4421 +
1.4422 +2008-06-29 Werner Lemberg <wl@gnu.org>
1.4423 +
1.4424 + * Version 2.3.7 released.

1.4446 +2008-06-28 Werner Lemberg <wl@gnu.org>
1.4447 +
1.4448 + * src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...
1.4449 + * src/ftcalc.c: Here. This fixes Savannah bug #23729.
1.4450 +
1.4451 +2008-06-27 Werner Lemberg <wl@gnu.org>
1.4452 +
1.4453 + * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
1.4454 + Horizontal_Gray_Sweep_Drop): Test for intersections which
1.4455 + degenerate to a single point can be ignored; this has been confirmed
1.4456 + by Greg Hitchcock from Microsoft. (This was commented out code.)
1.4457 +
1.4458 +2008-06-26 Werner Lemberg <wl@gnu.org>
1.4459 +
1.4460 + Improve navigation in API reference.
1.4461 +
1.4462 + * src/tools/docmaker/tohtml.py (html_header_3): Renamed to...
1.4463 + (html_header_6): This.
1.4464 + (html_header_3, html_header_3i, html_header_4, html_header_5,
1.4465 + html_header_5t): New strings.
1.4466 + (toc_footer_start, toc_footer_end): New strings.
1.4467 + (HtmlFormatter::html_header): Updated.
1.4468 + (HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header):
1.4469 + New strings.
1.4470 + (HtmlFormatter::index_enter): Use `html_index_header'.
1.4471 + (HtmlFormatter::index_exit): Print `html_footer'.
1.4472 + (HtmlFormatter::toc_enter): Use `html_toc_header'.
1.4473 + (HtmlFormatter::toc_exit): Print proper footer.
1.4474 +
1.4475 + Convert ~ to non-breakable space.
1.4476 +
1.4477 + * src/tools/docmaker/tohtml.py (make_html_para): Implement it.
1.4478 + Update header files accordingly.
1.4479 +
1.4480 +2008-06-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.4481 +
1.4482 + * builds/unix/configure.raw: Check type `ResourceIndex' explicitly
1.4483 + and define HAVE_TYPE_RESOURCE_INDEX if it is defined. Mac OS X 10.5
1.4484 + bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
1.4485 + ResourceIndex type definition. The macro does not inform the type
1.4486 + availability.
1.4487 + * src/base/ftmac.c: More parentheses are inserted to clarify the
1.4488 + conditionals to disable legacy APIs in `10.5 and later' cases. If
1.4489 + HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.
1.4490 +
1.4491 +2008-06-24 Werner Lemberg <wl@gnu.org>
1.4492 +
1.4493 + * src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
1.4494 + mode.
1.4495 +
1.4496 + * src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
1.4497 + Draw_Sweep): No-dropout mode is value 2, not value 0.
1.4498 + (Draw_Sweep): Really skip dropout handling for no-dropout mode.
1.4499 +
1.4500 +2008-06-24 Werner Lemberg <wl@gnu.org>
1.4501 +
1.4502 + * src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
1.4503 + if it consists of one point only. Based on a patch from Savannah
1.4504 + bug #23683 (from John Tytgat).
1.4505 +
1.4506 +2008-06-22 Werner Lemberg <wl@gnu.org>
1.4507 +
1.4508 + * src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff

1.4512 +
1.4513 +2008-06-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.4514 +
1.4515 + * builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
1.4516 + but LDFLAGS does not, import it to LDFLAGS. The option is used to
1.4517 + specify non-default SDK on Mac OS X (e.g., universal binary SDK for
1.4518 + Mac OS X 10.4 on PowerPC platform). Although Apple TechNote 2137
1.4519 + recommends to add the option only to CFLAGS, LDFLAGS should include
1.4520 + it because libfreetype.la is built with -no-undefined. This fixes a
1.4521 + bug reported by Ryan Schmidt in MacPorts,
1.4522 + http://trac.macports.org/ticket/15331.
1.4523 +
1.4524 +2008-06-21 Werner Lemberg <wl@gnu.org>
1.4525 +
1.4526 + Enable access to the various dropout rules of the B&W rasterizer.
1.4527 + Pass dropout rules from the TT bytecode interpreter to the
1.4528 + rasterizer.
1.4529 +
1.4530 + * include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
1.4531 + FT_OUTLINE_EXCLUDE_STUBS): New flags for FT_Outline.
1.4532 +
1.4533 + * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
1.4534 + Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
1.4535 + OpenType specification.
1.4536 + Fix mode 4 computation.
1.4537 + (Render_Glyph, Render_Gray_Glyph): Handle new outline flags.
1.4538 +
1.4539 + * src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
1.4540 + mode to FT_OUTLINE_XXX flags.
1.4541 +
1.4542 + * src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.
1.4543 +
1.4544 +2008-06-19 Werner Lemberg <wl@gnu.org>
1.4545 +
1.4546 + * src/cff/cffobjs.c (cff_face_init): Compute final
1.4547 + `dict->units_per_em' value before assigning it to
1.4548 + `cffface->units_per_EM'. Otherwise, CFFs without subfonts are
1.4549 + scaled incorrectly if the font matrix is non-standard. This fixes
1.4550 + Savannah bug #23630.
1.4551 +
1.4552 + * docs/CHANGES: Updated.

1.4570 + specification.
1.4571 +
1.4572 +2008-06-15 Werner Lemberg <wl@gnu.org>
1.4573 +

1.4691 +
1.4692 + * include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H,

1.4702 +
1.4703 + * src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses
1.4704 + original, unscaled input values. Confirmed by Greg Hitchcock from
1.4705 + Microsoft.
1.4706 +
1.4707 +2008-05-27 Werner Lemberg <wl@gnu.org>

1.4713 +
1.4714 + * src/raster/ftraster.c (fc_black_render): Return 0 when we are
1.4715 + trying to render into a zero-width/height bitmap, not an error code.
1.4716 +
1.4717 + * src/truetype/ttgload.c (load_truetype_glyph): Move initialization
1.4718 + of the graphics state for subglyphs to...
1.4719 + (TT_Hint_Glyph): This function.
1.4720 + Hinting instructions for a composite glyph apparently refer to the
1.4721 + just hinted subglyphs, not the unhinted, unscaled outline. This
1.4722 + seems to fix Savannah bugs #20973 and (at least partially) #23310.

1.4728 + proposed by an anonymous reporter of Savannah bug #23204.
1.4729 +
1.4730 +2008-05-18 Werner Lemberg <wl@gnu.org>
1.4731 +
1.4732 + * src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
1.4733 + correction for pixel boundary. Without this patch, the effect can
1.4734 + be cumulative under certain circumstances, making glyphs taller and
1.4735 + taller after each call. This fixes Savannah bug #19976.

1.4785 +
1.4786 + * src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
1.4787 + which contains a single but empty entry. This is technically
1.4788 + invalid (since it must end with `return'), but...

1.4798 + functions.
1.4799 +
1.4800 + * src/cff/cffobjs.h (CFF_Internal): New struct. It is used to
1.4801 + provide global hinting data for both the top-font and all subfonts
1.4802 + (with proper scaling).
1.4803 +
1.4804 + * src/cff/cffobjs.c (cff_make_private_dict): New function, using
1.4805 + code from `cff_size_init'.
1.4806 + (cff_size_init, cff_size_done, cff_size_select, cff_size_request):
1.4807 + Use CFF_Internal and handle subfonts.
1.4808 + (cff_face_init): Handle top-dict and subfont matrices correctly;
1.4809 + apply some heuristic in case of unlikely matrix concatenation
1.4810 + results. This has been discussed with people from Adobe (thanks
1.4811 + goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
1.4812 + and not correct.
1.4813 +
1.4814 + * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.

1.4834 +
1.4835 +2008-05-04 Werner Lemberg <wl@gnu.org>
1.4836 +
1.4837 + First steps to fix the scaling bug of CID-keyed CFF subfonts,
1.4838 + reported by Ding Li on 2008/03/28 on freetype-devel.
1.4839 +
1.4840 + * src/base/cff/cffparse.c (power_tens): New array.
1.4841 + (cff_parse_real): Rewritten to introduce a fourth parameter which
1.4842 + returns the `scaling' of the real number so that we have no
1.4843 + precision loss. This is not used yet.
1.4844 + Update all callers.
1.4845 + (cff_parse_fixed_thousand): Replace with...
1.4846 + (cff_parse_fixed_scaled): This function. Update all callers.
1.4847 +
1.4848 +2008-05-03 Werner Lemberg <wl@gnu.org>
1.4849 +
1.4850 + * src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without
1.4851 + transformation since it recursively calls FT_Load_Glyph. This fixes
1.4852 + Savannah bug #23143.
1.4853 +
1.4854 +2008-04-26 Werner Lemberg <wl@gnu.org>
1.4855 +
1.4856 + * include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x'

1.4858 + * src/psaux/psobjs.c (t1_builder_init): Updated.
1.4859 +

1.4874 +
1.4875 +2008-04-01 Werner Lemberg <wl@gnu.org>
1.4876 +
1.4877 + Fix compilation with g++ 4.1 (with both `single' and `multi'

1.4948 +
1.4949 + * src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
1.4950 + synthesis. For any face of a specified FOND, always the name for
1.4951 + the first face was used. Except of a FOND that refers multiple
1.4952 + Type1 font files, wrong synthesized font names are not used at all,
1.4953 + so this is an invisible bug. A few limit checks are added too.
1.4954 +
1.4955 + * builds/mac/ftmac.c: Ditto.

1.4959 + * builds/unix/configure.raw: Split compiler option to link Carbon
1.4960 + frameworks to one option for CoreServices framework and another
1.4961 + option for ApplicationServices framework. The split options can be
1.4962 + managed by GNU libtool to avoid unrequired duplication when FreeType

1.4977 +
1.4978 + * src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
1.4979 + handle by its value instead of ResError(), fix provided by Deron
1.4980 + Kazmaier. According to the Resource Manager Reference,
1.4981 + GetResource(), Get1Resource(), GetNamedResource(),
1.4982 + Get1NamedResource() and RGetResource() set noErr but return NULL
1.4983 + handle when they can not find the requested resource. These
1.4984 + functions never return undefined values, so it is sufficient to
1.4985 + check if the handle is not NULL.
1.4986 +
1.4987 + * builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.
1.4988 +
1.4989 +2008-02-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.4990 +
1.4991 + * src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other

1.4993 + builds/mac/ftmac.c is never included in any configuration.
1.4994 +
1.4995 + * builds/unix/configure.raw: Print warning if configure is executed
1.4996 + with options to specify Carbon functionalities explicitly.
1.4997 +
1.4998 + * docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not

1.5052 +
1.5053 + Improvement of POSIX resource-fork accessor to load unsorted
1.5054 + references in a resource. In HelveLTMM (resource-fork PostScript
1.5055 + Type1 font bundled with Mac OS X since 10.3.x), the appearance order
1.5056 + of PFB chunks is not sorted; sorting the chunks by reference IDs is
1.5057 + required.
1.5058 +

1.5091 + There exist CFFs which contain opcodes for the Type 1 operators
1.5092 + `hsbw' and `closepath' which are both invalid in Type 2 charstrings.
1.5093 + However, it doesn't harm to support them.

1.5147 +
1.5148 + Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is
1.5149 + not working since 2.3.5. In FT_Open_New(), if FT_New_Stream()
1.5150 + cannot mmap() the specified file and cannot seek to head of the
1.5151 + specified file, it returns NULL stream and FT_Open_New() returns the
1.5152 + error immediately. On MacOS, most legacy MacOS fonts fall into such
1.5153 + a scenario because their data forks are zero-sized and cannot be
1.5154 + sought. To proceed to guessing of resource fork fonts, the
1.5155 + functions for legacy MacOS font must properly handle the NULL stream
1.5156 + returned by FT_New_Stream().
1.5157 +
1.5158 + * src/base/ftobjs.c (IsMacBinary): Return error
1.5159 + FT_Err_Invalid_Stream_Operation immediately when NULL stream is
1.5160 + passed.
1.5161 + (FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
1.5162 + to fallback. Originally, legacy MacOS font is tested in the cases
1.5163 + of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
1.5164 + or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
1.5165 + .dfont header is combined). Now the case of
1.5166 + FT_Err_Cannot_Open_Stream is included.
1.5167 +
1.5168 + * src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
1.5169 + skip FT_Stream_Seek(), which seeks to the head of stream, and
1.5170 + proceed to unit testing of raccess_guess_XXX(). FT_Stream_Seek()
1.5171 + for a NULL stream causes a Bus error on Mac OS X.
1.5172 + (raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
1.5173 + immediately if passed stream is NULL.
1.5174 + (raccess_guess_apple_single): Ditto.

1.5177 +
1.5178 + Fix for Carbon incompatibilities since Mac OS X 10.5,
1.5179 + proposed by Sean McBride.
1.5180 +
1.5181 + * doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.
1.5182 +
1.5183 + * include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
1.5184 + FT_GetFilePath_From_Mac_ATS_Name. Since Mac OS X 10.5, calling
1.5185 + Carbon functions from a forked process is classified as unsafe
1.5186 + by Apple. All Carbon-dependent functions should be deprecated.
1.5187 +
1.5188 + * src/base/ftmac.c: Use essential header files
1.5189 + <CoreServices/CoreServices.h> and
1.5190 + <ApplicationServices/ApplicationServices.h> instead of
1.5191 + all-in-one header file <Carbon/Carbon.h>.
1.5192 +
1.5193 + Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
1.5194 + genuine macro PATH_MAX.
1.5195 +
1.5196 + Add fallback macro for kATSOptionFlagsUnRestrictedScope which
1.5197 + is not found in Mac OS X 10.0.
1.5198 +
1.5199 + Multi-character constants ('POST', 'sfnt' etc) are replaced by
1.5200 + 64bit constants calculated by FT_MAKE_TAG() macro.
1.5201 +
1.5202 + For the index in the segment of resource fork, new portable
1.5203 + type ResourceIndex is introduced for better compatibility.
1.5204 + This type is since Mac OS X 10.5, so it is defined as short
1.5205 + when built on older platforms.
1.5206 +
1.5207 + (FT_ATSFontGetFileReference): If build target is only the systems
1.5208 + 10.5 and newer, it calls Apple genuine ATSFontGetFileReference().
1.5209 +
1.5210 + (FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
1.5211 + and newer or 64bit platform, because legacy type FSSpec type is
1.5212 + removed completely.
1.5213 +
1.5214 + (FT_New_Face_From_FSSpec): Ditto.
1.5215 +
1.5216 +2007-11-01 Werner Lemberg <wl@gnu.org>
1.5217 +
1.5218 + * src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere. This
1.5219 + fixes Savannah bug #21485.
1.5220 +
1.5221 +2007-10-29 Daniel Svoboda <dasvo@planeta@cz>
1.5222 +
1.5223 + * src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver
1.5224 + can handle the font at all, then check `face_index'. Otherwise, the
1.5225 + driver might return the wrong error code. This fixes Savannah bug
1.5226 + #21468.
1.5227 +
1.5228 +2007-10-21 Werner Lemberg <wl@gnu.org>
1.5229 +
1.5230 + * src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare
1.5231 + support for bit 8 of the `fsSelection' field in the `OS/2' table.
1.5232 + MS is already using this; hopefully, this becomes part of OpenType
1.5233 + 1.5.
1.5234 + Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
1.5235 + (WWS_SUBFAMILY).
1.5236 +
1.5237 +2007-10-20 Werner Lemberg <wl@gnu.org>

1.5241 + (toc_section_enter): Use it.
1.5242 +
1.5243 +2007-10-18 David Turner <david@freetype.org>
1.5244 +
1.5245 + * include/freetype/freetype.h, src/base/ftobjs.c: Rename API
1.5246 + functions related to cmap type 14 support to the
1.5247 + `FT_Object_ActionName' scheme:
1.5248 +
1.5249 + FT_Get_Char_Variant_index -> FT_Face_GetCharVariantIndex
1.5250 + FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault

1.5253 + FT_Get_Chars_Of_Variant -> FT_Face_GetCharsOfVariant
1.5254 +
1.5255 + Update documentation accordingly.
1.5256 +
1.5257 + * src/sfnt/ttcmap.c: Stronger cmap 14 validation.
1.5258 + Make the code a little more consistent with FreeType coding
1.5259 + conventions and modify the cmap14 functions that returned a newly
1.5260 + allocated array to use a persistent vector from the TT_CMap14 object
1.5261 + instead.

1.6445 +
1.6446 +
1.6447 + * src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
1.6448 + (af_loader_load_g): Disable the warper (i.e., the light hinting
1.6449 + improvements) to make a 2.3.1 bugfix release before introducing a
1.6450 + new feature. This should give us more time to tune and improve the
1.6451 + warper for the next release.
1.6452 +
1.6453 + * docs/CHANGES: Update accordingly.
1.6454 +
1.6455 +2007-01-25 David Turner <david@freetype.org>
1.6456 +
1.6457 + For light auto-hinting, improve glyph advance widths and resurrect

1.6459 +
1.6460 + * src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'

1.6464 +

1.6469 + * src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.
1.6470 + (af_warper_compute): Handle `xmin_delta' and `xmax_delta'.

1.6487 +
1.6488 + * src/cff/cffload.c (cff_index_get_pointers): Handle last entry
1.6489 + correctly in a sanity check. Since this function is only used to
1.6490 + load local and global functions, any charstring that called the last
1.6491 + local/global function would fail otherwise. This fixes Savannah bug
1.6492 + #18867.
1.6493 +
1.6494 + * docs/CHANGES: Document it.
1.6495 +
1.6496 +2007-01-23 David Turner <david@freetype.org>

1.6503 + Fix and enable the warper to improve `light' hinting mode. This is
1.6504 + not necessarily a final version, but it seems to work well.

1.6506 + * src/autofit/aflatin.c (af_latin_hints_init) [AF_USE_WARPER]:

1.6618 + * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Fix memory stomping
1.6619 + bug in the bitmap emboldener if the pitch of the source bitmap is

1.6647 + Yamato.
1.6648 +
1.6649 + * autogen.sh: Small fix to get it working on Mac OS X properly:
1.6650 + The issue is that GNU libtool is called `glibtool' on this platform,
1.6651 + and we must call `glibtoolize', since `libtoolize' doesn't exist.
1.6652 +

1.6711 +
1.6712 +2007-01-04 David Turner <david@freetype.org>
1.6713 +
1.6714 + * src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts
1.6715 + correctly. This fixes Savannah bug #17876.
1.6716 +
1.6717 +
1.6718 + Do not allocate interpreter-specific tables in memory if we are not
1.6719 + going to load glyphs with the bytecode interpreter anyway.
1.6720 +
1.6721 + * src/truetype/ttgload.c (tt_loader_init): Load execution context
1.6722 + only if glyph is hinted.
1.6723 + Updated.
1.6724 + * src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready'
1.6725 + and `cvs_ready'.
1.6726 + Add `tt_size_ready_bytecode' declaration.
1.6727 + * src/truetype/ttobjs.c (tt_size_done_bytecode,

1.6730 + (tt_size_done): Move most code into `tt_size_done_bytecode'.
1.6731 + (tt_size_reset): Move some code to `tt_size_ready_bytecode'.
1.6732 +
1.6733 +
1.6734 + Don't extract the metrics table from the SFNT font file. Instead,
1.6735 + reparse it on each glyph load. The runtime difference is not
1.6736 + noticeable, and it can save a lot of heap memory when memory-mapped
1.6737 + files are not used.
1.6738 +
1.6739 + * include/freetype/internal/tttypes.h (TT_FaceRec): Add members
1.6740 + `horz_metrics_offset' and `vert_metrics_ofset'.
1.6741 + * src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics):

1.6746 +
1.6747 +
1.6748 + Do not load the CFF index offsets into memory, since this wastes a
1.6749 + *lot* of heap memory with large Asian CFF fonts. There is no
1.6750 + significant performance loss.
1.6751 +
1.6752 + * src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.
1.6753 + * src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and
1.6754 + `data_size'.
1.6755 + (CFF_CharsetRec): Add field `num_glyphs'.

1.6760 + (cff_index_init): This. Update all callers.
1.6761 + Updated -- some code has been moved to `cff_index_load_offsets'.

1.6763 + (cff_index_done): This. Update all callers.
1.6764 + (cff_index_get_pointers, cff_index_access_element): Updated to use
1.6765 + stream offsets.
1.6766 + (cff_charset_compute_cids): Set `num_glyphs' field.
1.6767 + (cff_encoding_load): Updated.

1.6788 + Make `grays' a pointer.
1.6789 + (TRaster): New structure.
1.6790 + (count_table): New static array.

1.6794 + (ft_black_init): Don't initialize `count_table'.

1.6796 + heap space for each FT_Library instance.
1.6797 +

1.6811 + src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove

1.6813 + the optimization is no longer experimental.
1.6814 +
1.6815 + * src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
1.6816 + Remove a typo that results in no hinting and a memory leak with some
1.6817 + large Asian CFF fonts.
1.6818 +
1.6819 + * src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
1.6820 + which happens when FT_Done_Library is called with still opened
1.6821 + CFF_Faces in it. We need to close all faces before destroying the
1.6822 + modules, or else some bad things (memory leaks) may happen.

1.6988 + Because FT_Load_Glyph expects CID values for CID-keyed fonts, the
1.6989 + test for a valid glyph index must be deferred to the font drivers.
1.6990 + This patch fixes Savannah bug #18301.
1.6991 +
1.6992 + * src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.
1.6993 + * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c
1.6994 + (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph),
1.6995 + src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c
1.6996 + (pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph),
1.6997 + src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c
1.6998 + (FNT_Load_Glyph): Check validity of `glyph_index'.

1.7000 +2006-11-13 David Turner <david@freetype.org>
1.7001 +
1.7002 + * src/truetype/ttinterp.c (FIX_BYTECODE): Undefine. The interpreter
1.7003 + `enhancements' are still too buggy for general use.
1.7004 +
1.7005 + * src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and
1.7006 + FT_FORCE_LEGACY_LCD_FILTER at compile time. Define these macros
1.7007 + when building the library to change the default LCD filter to be
1.7008 + used. This is only useful for experimentation.
1.7009 +
1.7010 + * include/freetype/ftlcdfil.h: Update documentation.
1.7011 +
1.7012 +2006-11-10 David Turner <david@freetype.org>
1.7013 +
1.7014 + * src/smooth/ftsmooth.c: API change for the LCD
1.7015 + filter. The FT_LcdFilter value is an enumeration describing which
1.7016 + filter to apply, with new values FT_LCD_FILTER_LIGHT and
1.7017 + FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
1.7018 + algorithm which produces strong color fringes for everything
1.7019 + except very-well hinted text).
1.7020 +
1.7021 + * include/freetype/ftlcdfil.h (FT_Library_SetLcdFilter): Change
1.7022 + second parameter to an enum type.

1.7033 + (FT_Bitmap_LcdFilterFunc): Change third argument to `FT_Library'.
1.7034 + (FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Add filtering
1.7035 + callback and update other fields.
1.7036 +
1.7037 + * src/smooth/ftsmooth.c (ft_smooth_render_generic)
1.7038 + [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Update.

1.7052 +
1.7053 + * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle vertical layout
1.7054 + also.
1.7055 +
1.7056 +2006-11-03 Werner Lemberg <wl@gnu.org>
1.7057 +
1.7058 + * src/base/ftcalc.c: Don't use `long long' but `FT_Int64'.

1.7061 +
1.7062 + Add a few tweaks to better handle serif fonts.
1.7063 + Add more debugging messages.
1.7064 +
1.7065 + * src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore

1.7067 + *many* corner cases with serifs.
1.7068 + (af_latin_align_linked_edge): Add logging message.
1.7069 + (af_latin_hint_edges): Use AF_HINTS_DO_BLUES.
1.7070 + Add logging messages.

1.7081 + ft_corner_is_flat): These declarations.
1.7082 +
1.7083 + * src/autofit/afangles.c (af_corner_orientation, af_corner_is_flat):
1.7084 + Comment out. Replaced by...
1.7085 +
1.7086 + * src/base/ftcalc.h (ft_corner_orientation, ft_corner_is_flat):
1.7087 + These functions. Update all callers.
1.7088 + (FT_Add64) [!FT_LONG64]: Simplify.
1.7089 +
1.7090 + * src/autofit/afhints.c: Include FT_INTERNAL_CALC_H.
1.7091 + (af_direction_compute): Add a missing FT_ABS call. This bug caused
1.7092 + production of garbage by missing lots of segments.
1.7093 +
1.7094 + * src/autofit/afhints.h (AF_HINTS_DO_BLUES): New macro.

1.7102 + and ft_corner_orientation.
1.7103 +
1.7104 +

1.7110 +
1.7111 + * src/base/ftobjs.c (FT_Select_Charmap): Disallow FT_ENCODING_NONE
1.7112 + as argument.

1.7114 +2006-10-23 Zhe Su <zsu@novell.com>
1.7115 +
1.7116 + * src/base/ftoutln.c (FT_Outline_Get_Orientation): Re-implement to
1.7117 + better deal with broken Asian fonts with strange glyphs, having
1.7118 + self-intersections and other peculiarities. The used algorithm is
1.7119 + based on the nonzero winding rule.
1.7120 +
1.7121 +2006-10-23 David Turner <david@freetype.org>
1.7122 +
1.7123 + Speed up the CFF font loader. With some large CFF fonts,

1.7232 +2006-09-28 David Turner <david@freetype.org>
1.7233 +
1.7234 + Fix a bug in the automatic unpatented hinting support which prevents

1.7236 +
1.7237 + * include/freetype/internal/ftobjs.h (FT_Face_InternalRec):

1.7247 +
1.7248 +
1.7249 + Add a new API to support color filtering of subpixel glyph bitmaps.
1.7250 + In a default build, the function `FT_Library_SetLcdFilter' returns
1.7251 + `FT_Err_Unimplemented_Feature'; you need to #define

1.7253 + real implementation.
1.7254 +
1.7255 + * include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files.

1.7261 +
1.7262 + * src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove arguments
1.7263 + `hmul' and `vmul'.
1.7264 +
1.7265 + Handle subpixel rendering.
1.7266 + Simplify function.
1.7267 + (ft_smooth_render_lcd): Use `FT_RENDER_MODE_LCD'.
1.7268 + (ft_smooth_render_lcd_v): Use `FT_RENDER_MODE_LCD_V'.
1.7269 +
1.7270 + * include/freetype/config/ftheader.h (FT_LCD_FILTER_H): New macro,
1.7271 + pointing to <freetype/ftlcdfil.h>.
1.7272 +
1.7273 + * src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC),
1.7274 + vms_make.com: Add `ftlcdfil.c' to the list of compiled source files.
1.7275 +
1.7276 + * modules.cfg (BASE_EXTENSIONS): Add ftlcdfil.c.

1.7294 +
1.7295 + * include/freetype/config/ftoption.h, devel/ftoption.h
1.7296 + (FT_CONFIG_OPTION_SUBPIXEL_RENDERING): New macro to control whether
1.7297 + we want to compile LCD-optimized rendering code (Ã la ClearType) or
1.7298 + not. The macro *must* be disabled in default builds of the library
1.7299 + for patent reasons.
1.7300 +
1.7301 + * src/smooth/ftsmooth.c (ft_smooth_render_generic): Disable
1.7302 + LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
1.7303 + isn't defined at compile time. This only changes the content of the
1.7304 + rendered glyph to match the one of normal gray-level rendering,
1.7305 + hence clients should not need to be modified.
1.7306 +
1.7307 + * docs/CHANGES: Updated.
1.7308 +

1.7318 + (platform,encoding) pair, with language_id != English.
1.7319 +
1.7320 + If the font uses another name entry with language_id == English, it
1.7321 + will be selected correctly, though.
1.7322 +
1.7323 + * src/truetype/ttobjs.c (tt_face_init): Add unpatented hinting

1.7344 + (gray_set_cell): Rewrite.
1.7345 + (gray_start_cell): Apply offsets to `ras.ex' and `ras.ey'.
1.7346 + (gray_render_span): Don't use FT_MEM_SET for small values.
1.7347 + (gray_dump_cells) [DEBUG_GRAYS]: New function.
1.7348 + (gray_sweep): Avoid buffer overwrites when to drawing the end of a

1.7763 + Public API of TrueTypeGX, OpenType, and classic kern table validator
1.7764 + should return `FT_Err_Unimplemented_Feature' if validation service

1.7766 + suggested by David Turner, cf.
1.7767 + http://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html

1.7789 +
1.7790 +2006-06-06 David Turner <david@freetype.org>
1.7791 +
1.7792 + Fix memory leak described in Savannah bug #16759.
1.7793 +
1.7794 + We change `ps_unicodes_init' so that it also takes a
1.7795 + `free_glyph_name' callback to release the glyph names returned by
1.7796 + `get_glyph_name'
1.7797 +
1.7798 + * include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc):

1.7816 +
1.7817 + * src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept
1.7818 + `item_size == 0' as well -- though this sounds weird, it can
1.7819 + theoretically happen. This fixes Savannah bug #16669.
1.7820 +
1.7821 + * src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
1.7822 + of `face->num_glyphs' which missed the last glyph, due to
1.7823 + the offset-by-1 computation, since the PFR format doesn't
1.7824 + guarantee that glyph index 0 corresponds to the `missing
1.7825 + glyph. This fixes Savannah bug #16668.

1.7833 +
1.7834 + * builds/win32/visualc/freetype.dsp: Release libraries no longer

1.7839 +
1.7840 + Apply patch by Derek Clegg to fix two memory leaks in the MacOS

1.7865 +2006-05-17 David Turner <david@freetype.org>
1.7866 +
1.7867 + This is a major patch used to drastically improve the performance of
1.7868 + loading glyphs. This both speeds up loading the glyph vectors
1.7869 + themselves and the auto-fitter module.
1.7870 +
1.7871 + We now use inline assembler code with GCC to implement `FT_MulFix',
1.7872 + which is probably the most important function related to the
1.7873 + engine's performance.
1.7874 +
1.7875 + The resulting speed-up is about 25%.
1.7876 +
1.7877 +
1.7878 + * include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
1.7879 + `cursor' and `limit'.

1.7882 + New functions.
1.7883 + (AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
1.7884 + [TEST]: Remove.
1.7885 +
1.7886 + * src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
1.7887 + code.
1.7888 +
1.7889 + * src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
1.7890 + `FT_ZERO'
1.7891 + (af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
1.7892 + (af_glyph_hints_reload: Rewrite recognition of weak points.
1.7893 +
1.7894 + * src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
1.7895 + constant values out of the loops.
1.7896 +
1.7897 + * src/autofit/aftypes.h: Updated.
1.7898 +
1.7899 + * src/base/ftcalc.c (FT_MulFix): Use inline assembler code.
1.7900 +
1.7901 + * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
1.7902 + product to get orientation.
1.7903 +
1.7904 + * src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
1.7905 + (FT_Stream_OpenGzip): Use it to handle small files directly in
1.7906 + memory.
1.7907 +
1.7908 + * src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
1.7909 + Improve performance.
1.7910 +
1.7911 + * src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
1.7912 + `limit'.
1.7913 +
1.7914 + (TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
1.7915 + TT_Load_Composite_Glyph): Updated. Add threshold to protect against
1.7916 + exceedingly large values of number of contours. Speed up by
1.7917 + reducing the number of loops.
1.7918 +
1.7919 + * src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.
1.7920 +
1.7921 +
1.7922 + * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
1.7923 + used to detect rogue clients from 4 to 16. This is to prevent some
1.7924 + segmentation faults with fonts like `KozMinProVI-Regular.otf' which
1.7925 + comes from the Japanese Adobe Reader Asian Font pack.

1.7927 +2007-05-17 Werner Lemberg <wl@gnu.org>
1.7928 +
