1.67 +
1.68 + Fix suggested by <octoploid@yandex.com>.
1.69 +
1.70 + * src/raster/ftraster.c (ULong): New typedef.
1.71 + (SCALED): Add proper cast.
1.72 +
1.73 +2013-05-04 Werner Lemberg <wl@gnu.org>
1.74 +
1.75 + Fix clang fixes.
1.76 +
1.77 + * src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate): Use
1.78 + correct types.
1.79 +
1.80 + * src/cff/cf2intrp.c (cf2_interpT2CharString) <default>: Force
1.81 + unsigned for computations.

1.87 +2013-05-04 Werner Lemberg <wl@gnu.org>
1.88 +
1.89 + [cff] Make Adobe CFF engine work correctly on 64bit hosts.
1.90 +
1.91 + Reported by numerous people on the `freetype-devel' list. Without
1.92 + this fix, glyphs aren't properly aligned on a common baseline.
1.93 +
1.94 + On 64bit systems, `FT_Pos' expands to `long int', having a width of
1.95 + 64bit. `CF2_Fixed' expands to `int' which is normally 32bit wide on
1.96 + 64bit hosts also. Wrong casts filled up the blues arrays with
1.97 + incorrect values. Note that all blues values are accessed with the
1.98 + `cf2_blueToFixed' macro which handles the 64bit to 32bit conversion.
1.99 +
1.100 + * src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues,
1.101 + cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for
1.102 + `data', not `CF2_Fixed'.
1.103 + * src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues,
1.104 + cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated.

1.106 +
1.107 +2013-05-04 Werner Lemberg <wl@gnu.org>
1.108 +
1.109 + More fixes for clang's `sanitize' feature.
1.110 +
1.111 + * src/base/ftcalc.c (FT_DivFix): Use unsigned values for
1.112 + computations which use the left shift operator and convert to signed
1.113 + as the last step.
1.114 + * src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate,
1.115 + FT_Vector_Length, FT_Vector_Polarize): Ditto.
1.116 +
1.117 + * src/cff/cffgload.c (cff_decoder_parse_charstrings): Simplify.
1.118 + * src/cff/cffload.c (cff_subfont_load): Fix constant.
1.119 + * src/cff/cffparse.c (cff_parse_integer, cff_parse_real, do_fixed,
1.120 + cff_parse_fixed_dynamic): Use unsigned values for computations which
1.121 + use the left shift operator and convert to signed as the last step.
1.122 +
1.123 + * src/cid/cidload.c (cid_get_offset): Ditto.
1.124 +
1.125 + * src/psaux/psconv.c (PS_Conv_ToFixed): Ditto.
1.126 + * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto.
1.127 +
1.128 + * src/truetype/ttinterp.c (TT_MulFix14, TT_DotFix14): Ditto.
1.129 +
1.130 +2013-05-04 Werner Lemberg <wl@gnu.org>
1.131 +
1.132 + Fix errors reported by clang's `sanitize' feature.
1.133 +
1.134 + * include/freetype/internal/ftstream.h: Simplify and fix integer
1.135 + extraction macros.
1.136 + (FT_INT8_, FT_BYTE_I16, FT_BYTE_I32, FT_INT8_I16, FT_INT8_I32,
1.137 + FT_INT8_I32, FT_INT8_U32): Removed.
1.138 + (FT_PEEK_SHORT, FT_PEEK_LONG, FT_PEEK_OFF3, FT_PEEK_SHORT_LE,
1.139 + FT_PEEK_LONG_LE, FT_PEEK_OFF3_LE): Use unsigned values for
1.140 + computations and convert to signed as the last step.
1.141 +
1.142 + * src/cff/cf2fixed.h (cf2_intToFixed, cf2_fixedToInt,
1.143 + cf2_fracToFixed): Avoid shifts of negative values.
1.144 + (cf2_intToFrac, cf2_fixedToFrac, cf2_fixedTo26Dot6): Removed,
1.145 + unused.
1.146 +
1.147 + * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR,
1.148 + default>: Use unsigned values for computations and convert to signed
1.149 + as the last step.
1.150 + Use proper types in tracing messages.
1.151 +
1.152 + * src/cff/cffgload.c (cff_decoder_parse_charstrings): Use unsigned
1.153 + values for computation of operands and convert to signed as the last
1.154 + step.
1.155 + Use proper type in tracing message.
1.156 +
1.157 +2013-05-03 Werner Lemberg <wl@gnu.org>
1.158 +
1.159 + * src/cff/cf2blues.c: Remove dead code.
1.160 +
1.161 +2013-05-02 Chris Liddell <chris.liddell@artifex.com>
1.162 +
1.163 + * src/cff/cffgload.c: Include FT_CFF_DRIVER_H.
1.164 +
1.165 +2013-04-27 Werner Lemberg <wl@gnu.org>
1.166 +
1.167 + * docs/CHANGES: Updated.
1.168 + * README: Improved.
1.169 +
1.170 +2013-04-13 Werner Lemberg <wl@gnu.org>
1.171 +
1.172 + [cff] Add a new Type 2 interpreter and hinter.
1.173 +
1.174 + This work, written by Dave Arnold <darnold@adobe.com> and fully
1.175 + integrated into FreeType by me, is a donation by Adobe in
1.176 + collaboration with Google. It is vastly superior to the old CFF
1.177 + engine, and it will replace it soon. Right now, it is still off by
1.178 + default, and you have to explicitly select it using the new
1.179 + `hinting-engine' property of the cff driver.
1.180 +
1.181 + For convenience, (most of) the new files are committed separately.
1.182 +
1.183 + * include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro.
1.184 + * include/freetype/ftcffdrv.h: New file to access CFF driver
1.185 + properties.
1.186 + * include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error
1.187 + code.
1.188 + * include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints',
1.189 + and `cf2interp'.
1.190 +
1.191 + * src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'.
1.192 + * src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine'
1.193 + and `no_stem_darkening'.
1.194 + * src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'.
1.195 +
1.196 + * src/cff/cff.c: Include new files.
1.197 + * src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle
1.198 + `hinting-engine' and `no-stem-darkening' properties (only the Adobe
1.199 + engine listens to them).
1.200 + * src/cff/cffgload.c: Include `cf2ft.h'.
1.201 + (cff_decoder_prepare): Initialize `current_subfont'.
1.202 + (cff_build_add_point): Handle Adobe engine which uses 16.16
1.203 + coordinates.
1.204 + (cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING
1.205 + separately.
1.206 + Choose rendering engine based on `hinting_engine' property.
1.207 + * src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe
1.208 + engine.
1.209 + * src/cff/cffobjs.c: Include FT_CFF_DRIVER_H.
1.210 + (cff_driver_init): Set default property values.
1.211 +
1.212 + * src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files.
1.213 +
1.214 + * src/cff/cf2*.*: New files, containing the Adobe engine.
1.215 +
1.216 +2013-04-12 Werner Lemberg <wl@gnu.org>
1.217 +
1.218 + [cff] Minor code administration issues.
1.219 +
1.220 + * src/cff/cffgload.c (check_points): Rename to...
1.221 + (cff_check_points): ...this and make it FT_LOCAL.
1.222 + (cff_builder_add_point, cff_builder_add_point1,
1.223 + cff_builder_start_point, cff_builder_close_contour,
1.224 + cff_lookup_glyph_by_stdcharcode, cff_get_glyph_data,
1.225 + cff_free_glyph_data): Make them FT_LOCAL.
1.226 +
1.227 + * src/cff/cffgload.h: Updated.
1.228 +
1.229 +2013-04-12 Werner Lemberg <wl@gnu.org>
1.230 +
1.231 + Add output bitmap checksums.
1.232 +
1.233 + Use `FT2_DEBUG=bitmap:3' for tracing.
1.234 +
1.235 + * src/base/md5.c, src/base/md5.h: New files, taken from
1.236 +
1.237 + http://openwall.info/wiki/people/solar/software/public-domain-source-code/md5
1.238 +
1.239 + * include/freetype/internal/fttrace.h: Add `bitmap'.
1.240 +
1.241 + * src/base/ftobjs.c [FT_DEBUG_LEVEL_TRACE]: Include `md5.c'
1.242 +
1.243 + (FT_Render_Glyph_Internal) [FT_DEBUG_LEVEL_TRACE]: For tracing,
1.244 + convert resulting bitmap to a uniform format and compute a checksum.
1.245 + Use `bitmap' category for the tracing message.
1.246 +
1.247 + * src/base/rules.mk (BASE_H): Updated.
1.248 +
1.249 + * docs/LICENSE.TXT: Updated.
1.250 +
1.251 +2013-04-12 Werner Lemberg <wl@gnu.org>
1.252 +
1.253 + [cff] Add framework for CFF properties.
1.254 +
1.255 + * include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC7):
1.256 + New macro.
1.257 +
1.258 + * src/cff/cffdrivr.c: Include FT_SERVICE_PROPERTIES_H.
1.259 + (cff_property_set, cff_property_get): New functions, still empty.
1.260 + Define `cff_service_properties' service.
1.261 + Update `cff_services'.
1.262 +
1.263 + * src/cff/cffpic.h: Include FT_SERVICE_PROPERTIES_H.
1.264 + (CFF_SERVICE_PROPERTIES_GET): New macro.
1.265 + (CffModulePIC): Add `cff_service_properties'.
1.266 +
1.267 +2013-04-03 Werner Lemberg <wl@gnu.org>
1.268 +
1.269 + [bdf] Fix Savannah bug #38589.
1.270 +
1.271 + * src/bdf/bdflib.c (_bdf_readstream): Thinko.
1.272 +
1.273 +2013-03-31 Werner Lemberg <wl@gnu.org>
1.274 +
1.275 + * configure: Use egrep, not grep.
1.276 +
1.277 + Problem reported Mojca Miklavec <mojca.miklavec.lists@gmail.com>.
1.278 +
1.279 +2013-03-29 Werner Lemberg <wl@gnu.org>
1.280 +
1.281 + * include/freetype/ftlcdfil.h: Add description of color filtering.
1.282 +
1.283 + Based on a contribution from Antti S. Lankila <alankila@bel.fi>
1.284 + (Savannah bug #38607).
1.285 +
1.286 +2013-03-23 Werner Lemberg <wl@gnu.org>
1.287 +
1.288 + [autofit] Minor.
1.289 +
1.290 + * src/autofit/afmodule.c (af_property_set): Typo.
1.291 + (af_autofitter_init, af_autofitter_done): Use cast.
1.292 +
1.293 +2013-03-21 Werner Lemberg <wl@gnu.org>
1.294 +
1.295 + * configure: Automatically test for `gmake' also.
1.296 +
1.297 + Suggested by Mojca Miklavec <mojca.miklavec.lists@gmail.com>.
1.298 +
1.299 +2013-03-21 Peter Breitenlohner <peb@mppmu.mpg.de>
1.300 +
1.301 + Respect CONFIG_SHELL from the environment.
1.302 +
1.303 + Some large packages using FreeType have to use a broken (deficient)
1.304 + /bin/sh. The configure scripts (as generated by Autoconf) are
1.305 + clever enough to find a better shell and put that one into the
1.306 + environment variable CONFIG_SHELL. If that environment variable is
1.307 + already set the script skips the test and assumes to be already
1.308 + running under a good shell.
1.309 +
1.310 + * builds/unix/detect.mk: Honour CONFIG_SHELL.
1.311 + * builds/unix/unix-def.in (SHELL): Define.
1.312 +
1.313 +2013-03-21 Werner Lemberg <wl@gnu.org>
1.314 +
1.315 + Fix Savannah patch #7971.
1.316 +
1.317 + * configure: Handle MAKE environment variable also.
1.318 +
1.319 +2013-03-17 Werner Lemberg <wl@gnu.org>
1.320 +
1.321 + Fix Savannah bug #38538.
1.322 +
1.323 + * builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c,
1.324 + builds/wince/ftdebug.c (FT_Throw): Add function.
1.325 +
1.326 +2013-03-17 Werner Lemberg <wl@gnu.org>
1.327 +
1.328 + [raster] Remove dead code.
1.329 +
1.330 + * src/raster/rastpic.c (ft_raster1_renderer_class_pic_init)
1.331 + src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it.
1.332 +
1.333 +2013-03-17 Werner Lemberg <wl@gnu.org>
1.334 +
1.335 + * src/pshinter/pshpic.h (GET_PIC): Use correct container.
1.336 +
1.337 +2013-03-15 Werner Lemberg <wl@gnu.org>
1.338 +
1.339 + * include/freetype/ftmoderr.h: Fix commit from 2013-03-11.
1.340 +
1.341 + The previous version was not backwards compatible. Reported by
1.342 + Behdad.
1.343 +
1.344 +2013-03-14 Werner Lemberg <wl@gnu.org>
1.345 +
1.346 + */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate.
1.347 +
1.348 + FT_Err_XXX and friends are no longer directly used in the source
1.349 + code.
1.350 +
1.351 +2013-03-14 Werner Lemberg <wl@gnu.org>
1.352 +
1.353 + New error management macros.
1.354 +
1.355 + * include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to...
1.356 + * include/freetype/fttypes.h: ... this file.
1.357 + (FT_ERR, FT_ERR_EQ, FT_ERR_NEQ, FT_MODERR_EQ, FT_MODERR_NEQ): New
1.358 + macros.
1.359 +
1.360 + * include/freetype/freetype.h: Updated.
1.361 +
1.362 +2013-03-14 Werner Lemberg <wl@gnu.org>
1.363 +
1.364 + */*: Use FT_Err_Ok only.
1.365 +
1.366 + This is a purely mechanical conversion.
1.367 +
1.368 +2013-03-14 Werner Lemberg <wl@gnu.org>
1.369 +
1.370 + */*: Use `FT_THROW'.
1.371 +
1.372 + This is essentially a mechanical conversion, adding inclusion of
1.373 + `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
1.374 + stand-alone compiling modes of the rasterizer modules.
1.375 +
1.376 + To convert the remaining occurrences of FT_Err_XXX and friends it is
1.377 + necessary to rewrite the code. Note, however, that it doesn't harm
1.378 + if some cases are not handled since FT_THROW is a no-op.
1.379 +
1.380 +2013-03-13 Werner Lemberg <wl@gnu.org>
1.381 +
1.382 + Introduce `FT_THROW' macro.
1.383 +
1.384 + The idea is to replace code like
1.385 +
1.386 + return FT_Err_Foo_Bar;
1.387 +
1.388 + or
1.389 +
1.390 + return CFF_Err_Foo_Bar;
1.391 +
1.392 + with
1.393 +
1.394 + return FT_THROW( Foo_Bar );
1.395 +
1.396 + The FT_THROW macro has two functions:
1.397 +
1.398 + . It hides the module specific prefix.
1.399 +
1.400 + . In debug mode, it calls the empty function `FT_Throw' which can
1.401 + be thus used to set a breakpoint.
1.402 +
1.403 + * include/freetype/internal/ftdebug.h (FT_THROW): New macro.
1.404 + (FT_Throw): New prototype.
1.405 + * src/base/ftdebug.c (FT_Throw): New function.
1.406 +
1.407 +2013-03-12 Werner Lemberg <wl@gnu.org>
1.408 +
1.409 + Remove `FT_KEEP_ERR_PREFIX'.
1.410 +
1.411 + The idea is to always have FT_ERR_PREFIX available internally.
1.412 +
1.413 + * include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard
1.414 + undefinition of FT_ERR_PREFIX
1.415 +
1.416 + * src/gxvalid/gxverror.h, src/otvalid/otverror.h,
1.417 + src/sfnt/sferrors.h: Updated.
1.418 +
1.419 +2013-03-11 Werner Lemberg <wl@gnu.org>
1.420 +
1.421 + [gxvalid] Fix module error.
1.422 +
1.423 + * src/gxvalid/gxverror.h (FT_ERR_BASE): Define as

1.750 + [truetype] Improve sub-pixel code.
1.751 +
1.752 + This patches fixes many issues with the ttsubpix implementation.
1.753 +
1.754 + 1. Data tables are defined, instead of declared, in the header, and
1.755 + thus copied into each source file that includes it.
1.756 +
1.757 + 2. These tables were defined as global, mutable, visible variables,
1.758 + and thus costing private RAM to every process that loads the
1.759 + library (> 50 KB / process, this is huge!).
1.760 +
1.761 + Additionally, this also made the library export the symbols
1.762 + completely needlessly.
1.763 +
1.764 + 3. Missing `sph_' and `SPH_' prefixes to some of the definitions.
1.765 +
1.766 + Note that this doesn't try to fix the incredibly inefficient storage
1.767 + format for the data tables used by the code. This one will require
1.768 + another pass in the future.
1.769 +

1.795 + [truetype] Improve accuracy of normalization of short vectors.
1.796 +
1.797 + Unit vector components are stored as 2.14 fixed-point numbers. In
1.798 + order to calculate all 14 bits accurately, a short vector to be
1.799 + normalized has to be upscaled to at least 14 bits before its length
1.800 + is calculated. This has been safe since accurate CORDIC algorithms

1.807 + [truetype] Kill very old vector normalization hacks.
1.808 +
1.809 + Back in the days, vector length calculations were not very accurate
1.810 + and the vector normalization function, Normalize, had to meticulously
1.811 + correct the errors for long vectors [commit b7ef2b096867]. It was no

1.956 +
1.957 + [base] Improve trigonometric core.
1.958 +
1.959 + FreeType used to rely on a 24-step iteration CORDIC algorithm to
1.960 + calculate trigonometric functions and rotate vectors. It turns out
1.961 + that once the vector is in the right half-plane, the initial rotation
1.962 + by 63 degrees is not necessary. The algorithm is perfectly capable
1.963 + to converge to any angle starting from the second 45 degree rotation.
1.964 + This patch removes the first rotation and makes it a 23-step CORDIC
1.965 + algorithm.

1.1057 +
1.1058 + Since the initial commit (ebe85f59) the value of FT_TRIG_SCALE has
1.1059 + always been slightly less than the correct value, which has been

1.1088 +
1.1089 + [truetype] Scale F_dot_P down.
1.1090 +
1.1091 + The dot product between freeVector and projVector or cosine of
1.1092 + the angle between these FT_F2Dot14 unit vectors used to be scaled up
1.1093 + by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P.
1.1094 + This patch scales the value down by 2^14 instead, which simplifies
1.1095 + its use throughout the bytecode interpreter.
1.1096 +
1.1097 + This does not lead to the loss of precision because the lower bits
1.1098 + are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8)
1.1099 + for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666.
1.1100 + These vectors are stored as (0x4000,0) and (0x2666,0x3333) after
1.1101 + rounding and F_dot_P is assigned 0x26660000. The lower bits were
1.1102 + already lost while rounding the unit vector components.
1.1103 +
1.1104 + Besides code simplification, this change can lead to better
1.1105 + performance when FT_MulDiv with the scaled-down F_dot_P is less
1.1106 + likely to use the costly 64-bit path. We are not changing the type
1.1107 + of F_dot_P to FT_F2Dot14 at this point.
1.1108 +
1.1109 + * src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14
1.1110 + bits and modify its use accordingly.
1.1111 + (Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify
1.1112 + the use of F_dot_P field.
1.1113 + * src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary
1.1114 + assignment of F_dot_P to its theoretical maximum in case we decide
1.1115 + to scale back its type later.

1.1390 +
1.1391 + `rm -f' is directly used in the `configure' script created by

1.1429 +
1.1430 + This is an improved version of a similar fix contained in the
1.1431 + so-called `Infinality patch', taken from
1.1432 +
1.1433 + http://www.infinality.net/fedora/linux/zips/freetype-infinality-2.4.10-20120616_01-x86_64.tar.bz2
1.1434 +
1.1435 + which addresses various enhancements of the auto-hinter. Without
1.1436 + properties to control a module's metadata it wasn't possible to
1.1437 + adapt the patches because everything was originally controlled by
1.1438 + environment variables which I consider not suitable in general.
1.1439 +
1.1440 + A patch to control `increase_x_height' follows.
1.1441 +

1.1516 +

1.1971 +
1.1972 + [truetype] Support subpixel hinting.
1.1973 +
1.1974 + This is the large, famous `Infinality' patch to support ClearType
1.1975 + bytecode which has been available from
1.1976 + http://www.infinality.net/blog/ for some time, and which has been
1.1977 + refined over the last years. While still experimental, it is now
1.1978 + mature enough to be included directly into FreeType.
1.1979 +
1.1980 + Most of the code is based on the ClearType whitepaper written by
1.1981 + Greg Hitchcock
1.1982 +
1.1983 + http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
1.1984 +
1.1985 + which gives a detailed overview of the necessary changes to the
1.1986 + Microsoft rasterizer so that older fonts are supported. However, a
1.1987 + lot of details are still missing, and this patches provides a
1.1988 + framework to easily handle rendering issues down to the glyph level
1.1989 + of certain fonts.
1.1990 +
1.1991 + Note that ClearType support is not completely implemented! In
1.1992 + particular, full support for the options `compatible_widths',
1.1993 + `symmetrical_smoothing, and `bgr' (via the GETINFO bytecode
1.1994 + instruction) is missing.

1.2235 + [type1] Fix Savannah bug #35833.
1.2236 +
1.2237 + Based on the patch given in the bug report.
1.2238 +
1.2239 + * src/type1/t1load.c (IS_INCREMENTAL): New macro.

1.2244 +
1.2245 + [autofit] Return correct linear advance width values.
1.2246 +
1.2247 + This was quite a subtle bug which accidentally showed up with glyph
1.2248 + `afii10023' of arial.ttf (version 2.76). This glyph is a composite;
1.2249 + the first component, `E', has an advance width of 1366 font units,
1.2250 + while the advance width of the composite itself (which looks like
1.2251 + uppercase `E' with dieresis) is 1367 font units. I think this is
1.2252 + actually a bug in the font itself, because there is no reason that
1.2253 + this glyph has not the same width as uppercase `E' without the
1.2254 + dieresis. Anyway, it helped identify this problem.
1.2255 +
1.2256 + Using the TrueType hinter, the correct value (1367) of `afii10023'
1.2257 + was returned, but the autohinter mysteriously returned 1366.
1.2258 +
1.2259 + Digging in the code showed that the autohinter recursively calls
1.2260 + FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load
1.2261 + flag. However, the `linearHoriAdvance' field is still returned as a
1.2262 + scaled value. To avoid scaling twice, the old code in autofit reset
1.2263 + `linearHoriAdvance', using the `horiAdvance' field. This seemed to
1.2264 + work since FT_LOAD_NO_SCALE was in use, but it failed actually,
1.2265 + because `horiAdvance' is defined as the distance of the first
1.2266 + subglyph's phantom points, which in turn are initialized using the
1.2267 + advance width of the first subglyph. And as the given example
1.2268 + shows, these widths can differ.
1.2269 +
1.2270 + * src/autofit/afloader.c (af_loader_load_g): Temporarily set
1.2271 + FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled
1.2272 + values for the linear advance widths.

1.2276 + [truetype] Fix SSW instruction.
1.2277 +
1.2278 + * src/truetype/ttinterp.c (DO_SSW): SSW *does* use font units. For
1.2279 + verification, it took some time to find a font which actually uses
1.2280 + this instruction.

1.2749 + FT_Init_Class_cff_cmap_unicode_class_rec() are removed.
1.2750 + They can be obtained by the inclusion of cffcmap.h.
1.2751 + cffcmap.h invokes FT_DECLARE_CMAP_CLASS() and it declares

1.2753 +
1.2754 +2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.2755 +
1.2756 + Fix redundant declaration warning in PIC mode.
1.2757 +
1.2758 + Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
1.2759 + designed to declare xxx_pic_{free,init} by themselves.
1.2760 + Because these macros are used at the end of the module
1.2761 + interface (e.g. ttdriver.c) and the wrapper source to build
1.2762 + a module as a single object (e.g. truetype.c) includes
1.2763 + the PIC file (e.g. ttpic.c) before the module interface,
1.2764 + these macros are expanded AFTER xxx_pic_{free,init} body
1.2765 + when the modules are built as single object.
1.2766 + The declaration after the implementation causes the redundant
1.2767 + declaration warnings, so the declarations are moved to module
1.2768 + PIC headers (e.g. ttpic.h). Separating to other header files
1.2769 + are needed for multi build.
1.2770 +
1.2771 + * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):
1.2772 + Remove class_##_pic_free and class_##_pic_init declarations.
1.2773 + * include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,
1.2774 + FT_DEFINE_MODULE): Ditto.
1.2775 +
1.2776 + * src/base/basepic.h: Insert a comment and fix coding style.
1.2777 + * src/autofit/afpic.h: Declare autofit_module_class_pic_{free,
1.2778 + init}.
1.2779 + * src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}.
1.2780 + * src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free,
1.2781 + init}.
1.2782 + * src/psnames/pspic.h: Declare psnames_module_class_pic_{free,
1.2783 + init}.

1.2799 + [base] Fix a dereference of uninitialized variable in PIC mode.
1.2800 +
1.2801 + * src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be

1.2882 +
1.2883 + [mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.
1.2884 +
1.2885 + Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
1.2886 + was a configurable macro to disable Carbon-dependent code. Because
1.2887 + now configure script sets DARWIN_NO_CARBON by default and disables
1.2888 + Darwin & Carbon-dependent codes, these macros can be unified.
1.2889 + FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
1.2890 + (defined by default) is removed, because DARWIN_NO_CARBON violates
1.2891 + FT_XXX naming convention of public macros, and a macro configured by
1.2892 + default is not portable for the building without configure (e.g.
1.2893 + make devel).
1.2894 +
1.2895 + * builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
1.2896 + old Mac font support is requested and Carbon is available.
1.2897 + * builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support
1.2898 + for Mac OS X without Carbon (e.g. Mac OS X 10.4 for ppc64) is
1.2899 + requested.

1.2967 + [bdf] Fix Savannah bug #34896.
1.2968 +
1.2969 + ENCODING now covers the whole Unicode range.
1.2970 +
1.2971 + Note, however, that this change is quite expensive since it
1.2972 + increases the size of three arrays by almost 400kByte in total. The
1.2973 + right fix is to replace the logic with something smarter.
1.2974 + Additionally, there exist very old BDFs for three-byte CCCII

1.2976 + a smarter logic).
1.2977 +
1.2978 + * src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod'

1.3273 +
1.3274 + Slightly improve LZW_CLEAR handling.
1.3275 +
1.3276 + * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
1.3277 + Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
1.3278 + handled as clear codes. This also re-sets old_code and old_char to
1.3279 + predictable values, which is a little better than using `random'
1.3280 + ones if the code following LZW_CLEAR is invalid.
1.3281 +
1.3282 +2011-09-11 Tomas Hoger <thoger@redhat.com>
1.3283 +
1.3284 + Add explicit LZW decompression stack size limit.
1.3285 +
1.3286 + Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
1.3287 + constructed correctly. It's even less than that, see e.g.
1.3288 + libarchive code comment for a better size upper bound:
1.3289 +
1.3290 + http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121
1.3291 +
1.3292 + This patch adds explicit stack size limit, enforced when stack is
1.3293 + realloced.
1.3294 +
1.3295 + An alternative is to ensure that code < state->prefix[code - 256]
1.3296 + when traversing prefix table. Such check is less efficient and
1.3297 + should not be required if prefix table is constructed correctly in
1.3298 + the first place.

1.3300 + * src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.

1.3302 +2011-09-11 Tomas Hoger <thoger@redhat.com>
1.3303 +
1.3304 + Protect against loops in the prefix table.
1.3305 +
1.3306 + LZW decompressor did not sufficiently check codes read from the
1.3307 + input LZW stream. A specially-crafted or corrupted input could
1.3308 + create a loop in the prefix table, which leads to memory usage
1.3309 + spikes, as there's no decompression stack size limit.
1.3310 +
1.3311 + * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First
1.3312 + code in valid LZW stream must be 0..255.
1.3313 + <FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,
1.3314 + code > free_ent is invalid.

1.3529 +
1.3530 + [ftstroke] Major revision.
1.3531 +
1.3532 + The main problems
1.3533 + -----------------
1.3534 +
1.3535 + o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
1.3536 + joins (not bevel joins) were generated. Indeed, the meanings of
1.3537 + `miter' and `bevel' were incorrectly reversed (consistently) in
1.3538 + both the code and comments.
1.3539 +
1.3540 + o The way bevel joins were constructed (whether specified
1.3541 + explicitly, or created as a result of exceeding the miter limit)
1.3542 + did not match what is required for stroked text in PostScript or
1.3543 + PDF.
1.3544 +
1.3545 + The main fixes
1.3546 + --------------
1.3547 +
1.3548 + o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
1.3549 +
1.3550 + o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
1.3551 + introduced to support PostScript and PDF miter joins.
1.3552 +
1.3553 + o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
1.3554 + alias for FT_STROKER_LINEJOIN_MITER.
1.3555 +
1.3556 + Additionally, a variety of stroking errors have been fixed. These
1.3557 + would cause various artifacts (including points `at infinity'),
1.3558 + especially when stroking poor quality fonts.
1.3559 +
1.3560 + See
1.3561 +
1.3562 + http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html
1.3563 +
1.3564 + for example documents. The FreeType stroker now produces results
1.3565 + very similar to that produced by GhostScript and Distiller for these
1.3566 + fonts.
1.3567 +
1.3568 + Other problems
1.3569 + --------------
1.3570 +
1.3571 + The following problems have been resolved:
1.3572 +
1.3573 + o Inside corners could be generated incorrectly. Intersecting the
1.3574 + inside corner could cause a missing triangular area and other
1.3575 + effects.
1.3576 +
1.3577 + The intersection point can only be used if the join is between
1.3578 + two lines and both lines are long enough. The `optimization'
1.3579 + condition in `ft_stroker_inside' has been corrected; this
1.3580 + requires the line length to be passed into various functions and
1.3581 + stored in `FT_StrokerRec'.
1.3582 +
1.3583 + o Incorrect cubic curves could be generated. The angle
1.3584 + calculations in `FT_Stroker_CubicTo' have been corrected to
1.3585 + handle the case of the curve crossing the +/-PI direction.
1.3586 +
1.3587 + o If the border radius was greater than the radius of curvature of
1.3588 + a curve, then the negative sector would end up outside (not
1.3589 + inside) the border. This situation is now recognized and the
1.3590 + negative sector is circumnavigated in the opposite direction.
1.3591 + (If round line joins are being used, this code is disabled
1.3592 + because the line join will always cover the negative sector.)
1.3593 +
1.3594 + o When a curve is split, the arcs may not join smoothly (especially
1.3595 + if the curve turns sharply back on itself). Changes in
1.3596 + direction between adjacent arcs were not handled. A round
1.3597 + corner is now added if the deviation from one arc to the next is
1.3598 + greater than a suitable threshold.
1.3599 +
1.3600 + o The current direction wasn't retained if a the outline contained
1.3601 + a zero length lineto or a curve that was determined to be
1.3602 + `basically a point'. This could cause a spurious join to be
1.3603 + added.
1.3604 +
1.3605 + o Cubics with close control points could be mishandled. All eight
1.3606 + cases are now distinguished correctly.
1.3607 +
1.3608 + Other improvements
1.3609 + ------------------
1.3610 +
1.3611 + o Borders for cubic curves could be too `flat'.
1.3612 + FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent
1.3613 + this.
1.3614 +
1.3615 + o The handling and use of movable points has been simplified a
1.3616 + little.
1.3617 +
1.3618 + o Various values are now computed only if the results are actually
1.3619 + needed.
1.3620 +
1.3621 + o The directions of the outer and inner borders have been swapped,
1.3622 + as recommended by Graham Asher.

1.3750 + [gxvalid] Cleanup.

1.4197 +
1.4198 + Previously, signed integers were converted to unsigned integers, but

1.4475 +
1.4476 + Right before B/W rasterizing, the bbox gets simply rounded to

1.4511 +
1.4512 + This catches a rendering problem with glyph `x' from Tahoma at

1.4521 +
1.4522 + If a drop-out rule would switch on a pixel outside of the glyph's
1.4523 + bounding box, use the right (or top) pixel instead. This is an
1.4524 + undocumented feature, but some fonts like `Helvetica Neue LT Com 65
1.4525 + Medium' heavily rely on it.

1.4534 + [cache] Fix Savannah bug #31923, patch drafted by Harsha.
1.4535 +
1.4536 + When a node comparator changes the cached nodes during the
1.4537 + search of a node matching with queried properties, the
1.4538 + pointers obtained before the function should be updated to
1.4539 + prevent the dereference to freed or reallocated nodes.
1.4540 + To minimize the rescan of the linked list, the update is
1.4541 + executed when the comparator notifies the change of cached
1.4542 + nodes. This change depends previous change:

1.4549 +2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.4550 +
1.4551 + [cache] Notice if a cache query induced the node list change.
1.4552 +
1.4553 + Some node comparators (comparing the cache node contents and the
1.4554 + properties specified by the query) can flush the cache node to
1.4555 + prevent the cache inflation. The change may invalidate the pointers
1.4556 + to the node obtained before the node comparison, so it should be
1.4557 + noticed to the caller. The problem caused by the cache node
1.4558 + changing is reported by Harsha, see Savannah bug #31923.
1.4559 +
1.4560 + * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument

1.4616 +
1.4617 + [cache] Deduplicate the code to get the top node by a hash.
1.4618 +
1.4619 + There are several duplicated code fragments getting the top node

1.4626 +
1.4627 + To remove duplication, a cpp-macro to do same work

1.4770 + Apply Savannah patch #7422.
1.4771 +
1.4772 + If we encounter a space in a string then the sbit buffer is NULL,
1.4773 + height and width are 0s. So the check in ftc_snode_compare will
1.4774 + always pass for spaces (comparision with 255). Here the comments
1.4775 + above the condition are proper but the implementation is not. When
1.4776 + we create an snode I think it is the proper way to initialize the
1.4777 + width to 255 and then put a check for being equal to 255 in snode
1.4778 + compare function.

1.5209 + [smooth] Fix and improve spline flattening.
1.5210 +
1.5211 + This fixes the flattening of cubic, S-shaped curves and speeds up
1.5212 + the handling of both the conic and cubic arcs.
1.5213 +
1.5214 + See the discussions on the freetype-devel mailing list in late
1.5215 + August and September 2010 for details.
1.5216 +

1.5226 + Minor fixes.
1.5227 +
1.5228 + * src/cff/cffload.c (cff_charset_compute_cids): `charset->sids[i]'
1.5229 + is `FT_UShort'.
1.5230 + (cff_index_access_element): Don't use additions in comparison.
1.5231 + * src/sfnt/ttpost.c (load_format_20): Make `post_limit' of type

1.5238 +2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.5239 +
1.5240 + [cff] Truncate the element length at the end of the stream.
1.5241 + See Savannah bug #30975.
1.5242 +
1.5243 + * src/cff/cffload.c (cff_index_access_element): `off2', the offset
1.5244 + to the next element is truncated at the end of the stream to prevent
1.5245 + invalid I/O. As `off1', the offset to the requested element has
1.5246 + been checked by `FT_STREAM_SEEK', `off2' should be checked
1.5247 + similarly.
1.5248 +
1.5249 +2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.5250 +
1.5251 + [cff] Ignore CID > 0xFFFFU.
1.5252 + See Savannah bug #30975.
1.5253 +
1.5254 + * src/cff/cffload.c (cff_charset_compute_cids): Ignore CID if
1.5255 + greater than 0xFFFFU. CFF font spec does not mention maximum CID in
1.5256 + the font, but PostScript and PDF spec define that maximum CID is
1.5257 + 0xFFFFU.
1.5258 +
1.5259 +2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

1.5264 + * src/cff/cffload.c (cff_charset_load): Report the original `nleft'
1.5265 + and truncated `nleft'.

1.5270 + See Savannah bug #30975.
1.5271 +
1.5272 + * src/cff/cffload.c (cff_charset_compute_cids): Don't increment
1.5273 + max_cid after detecting max CID. The array CFF_Charset->cids is
1.5274 + allocated by max_cid + 1.
1.5275 + (cff_charset_cid_to_gindex): Permit CID is less than or equal to
1.5276 + CFF_Charset->max_cid.
1.5277 + * src/cff/cffobjs.c (cff_face_init): FT_Face->num_glyphs is
1.5278 + calculated as CFF_Charset->max_cid + 1.

1.5282 + [truetype] Sanitize the broken offsets in `loca'.
1.5283 + See Savannah bug #31040.
1.5284 +
1.5285 + * src/truetype/ttpload.c (tt_face_get_location): If `pos1', the
1.5286 + offset to the requested entry in `glyf' exceeds the end of the
1.5287 + table, return offset=0, length=0. If `pos2', the offset to the next
1.5288 + entry in `glyf' exceeds the end of the table, truncate the entry
1.5289 + length at the end of `glyf' table.

1.5293 + [sfnt] Prevent overrunning in `post' table parser.
1.5294 + See Savannah bug #31040.
1.5295 +
1.5296 + * src/sfnt/ttpost.c (load_post_names): Get the length of `post'
1.5297 + table and pass the limit of `post' table to `load_format_20' and
1.5298 + `load_format_25'.
1.5299 + (load_format_20): Stop the parsing when we reached at the limit of
1.5300 + `post' table. If more glyph names are required, they are filled by
1.5301 + NULL names.
1.5302 +
1.5303 +2010-09-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.5304 +
1.5305 + [truetype] Don't duplicate size->twilight structure to be freed.
1.5306 + See Savannah bug #31040 for detail.
1.5307 +
1.5308 + * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate
1.5309 + FT_GlyphZoneRec size->twilight to be freed. If duplicated,
1.5310 + `FT_FREE' erases the duplicated pointers only and leave original
1.5311 + pointers. They can cause the double-free crash when the burst
1.5312 + errors occur in TrueType interpreter and `free_buffer_in_size' is
1.5313 + invoked repeatedly.
1.5314 +
1.5315 +2010-09-15 Werner Lemberg <wl@gnu.org>
1.5316 +
1.5317 + Make bytecode debugging with FontForge work again.
1.5318 +
1.5319 + * src/truetype/ttinterp.c (TT_RunIns): Don't call
1.5320 + `free_buffer_in_size' in case of error if a debugger is active.
1.5321 +
1.5322 +2010-09-14 Werner Lemberg <wl@gnu.org>
1.5323 +
1.5324 + Improve tracing messages.

1.5326 + * src/truetype/ttinterp.c (TT_RunIns): Improve wording of tracing
1.5327 + message.
1.5328 + * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Add
1.5329 + tracing message.
1.5330 + * src/truetype/ttgload.c (tt_loader_init): Add tracing message.
1.5331 + * src/cache/ftcsbits.c (ftc_snode_load): Emit tracing message if
1.5332 + glyph doesn't fit into a small bitmap container.
1.5333 +
1.5334 +2010-09-13 Werner Lemberg <wl@gnu.org>
1.5335 +
1.5336 + Fix minor issues reported by <muktha.narayan@wipro.com>.
1.5337 +
1.5338 + * src/autofit/aflatin.c (af_latin_compute_stem_width): Remove
1.5339 + redundant conditional check.
1.5340 + * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto.
1.5341 + * src/cff/cffload.c (cff_encoding_load): Remove conditional check
1.5342 + which always evaluates to `true'.
1.5343 + * src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points):
1.5344 + Ditto.
1.5345 + * src/truetype/ttinterp.c (Ins_IUP): Ditto.
1.5346 + * src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if
1.5347 + value is already dereferenced.
1.5348 + * src/winfonts/winfnt.c (FNT_Load_Glyph): Fix check of `face'.
1.5349 +
1.5350 +2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.5351 +
1.5352 + Ignore the environmental setting of LIBTOOL.
1.5353 + Patch is suggested by Adrian Bunk, to prevent unexpected
1.5354 + reflection of environmental LIBTOOL. See:
1.5355 + http://savannah.nongnu.org/patch/?7290
1.5356 +
1.5357 + * builds/unix/unix-cc.in: LIBTOOL is unconditionally set to
1.5358 + $(FT_LIBTOOL_DIR)/libtool. FT_LIBTOOL_DIR is set to $(BUILD_DIR)
1.5359 + by default.
1.5360 + * configure: When configured for the building out of source tee,
1.5361 + FT_LIBTOOL_DIR is set to $(OBJ_DIR).
1.5362 +
1.5363 +2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.5364 +
1.5365 + [truetype] Decrease the trace level catching the interpreter error.
1.5366 +
1.5367 + * src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level
1.5368 + showing the error when the interpreter returns with an error,
1.5369 + from` FT_TRACE7' to `FT_TRACE1'.
1.5370 +
1.5371 +2010-08-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.5372 +
1.5373 + [truetype] Prevent bytecode reuse after the interpretation error.
1.5374 +
1.5375 + * src/truetype/ttinterp.c (free_buffer_in_size): New function to
1.5376 + free the buffer allocated during the interpretation of this glyph.
1.5377 + (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if
1.5378 + an error occurs in the bytecode interpretation. The interpretation
1.5379 + of invalid bytecode may break the function definitions and referring
1.5380 + them in later interpretation is danger. By unsetting these flags,
1.5381 + `fpgm' and `prep' tables are executed again in next interpretation.
1.5382 +
1.5383 + This fixes Savannah bug #30798, reported by Robert Święcki.
1.5384 +
1.5385 +2010-08-29 Werner Lemberg <wl@gnu.org>
1.5386 +
1.5387 + [ftraster] Pacify compiler.
1.5388 +

1.5390 + not used.
1.5391 +
1.5392 +2010-08-29 Werner Lemberg <wl@gnu.org>
1.5393 +
1.5394 + [cff] Allow SIDs >= 65000.
1.5395 +
1.5396 + * src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20:
1.5397 + The threshold for SIDs is not applicable here. I misinterpreted the
1.5398 + `SID values 65000 and above are available for implementation use'
1.5399 + sentence in the CFF specification.

1.5404 +
1.5405 + Force hinting when the font lacks its familyname.
1.5406 +
1.5407 + In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt
1.5408 + stream may lack `name' table because they are not required. Hinting
1.5409 + for nameless fonts is safer for PDFs including embedded Chinese
1.5410 + fonts. Written by David Bevan, see:

1.6163 +
1.6164 + [psaux] Fix Savannah bug #29846.
1.6165 +
1.6166 + Previously we discovered fonts which used `setcurrentpoint' to set
1.6167 + the initial point of a contour to 0,0. This caused FreeType to
1.6168 + raise an error, because the `setcurrentpoint' operator is only
1.6169 + supposed to be used with the results from an OtherSubr subroutine.
1.6170 +
1.6171 + This was fixed by simply ignoring the error and carrying on.
1.6172 +
1.6173 + Now we have found a font which uses setcurrentpoint to actually
1.6174 + establish a non-zero point for a contour during the course of a
1.6175 + glyph program. FWIW, these files may be produced by an application
1.6176 + called `Intaglio' on the Mac, when converting TrueType fonts to
1.6177 + Type 1.
1.6178 +
1.6179 + The fix allows the new invalid behaviour, the old invalid behaviour
1.6180 + and real proper usage of the operator to work the same way as Adobe
1.6181 + interpreters apparently do.
1.6182 +
1.6183 + * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make
1.6184 + `setcurrentpoint' use the top two elements of the stack to establish
1.6185 + unconditionally the current x and y coordinates.
1.6186 +
1.6187 + Make the `flex' subroutine handling (OtherSubr 0) put the current
1.6188 + x,y coordinates onto the stack, instead of two dummy uninitialised
1.6189 + values.
