 123
 124         * src/bdf/bdflib.c (bdf_load_font): Fix small memory leak (#46480).

 137 2015-11-20  Werner Lemberg  <wl@gnu.org>
 138
 139         Add `FT_LCD_FILTER_LEGACY1' enum value.
 140
 141         This does the same as `FT_LCD_FILTER_LEGACY'.
 142
 143         See
 144
 145           https://bugs.freedesktop.org/show_bug.cgi?id=92981

 177         similar rendering style.
 178
 179         * include/freetype/freetype.h: Mention that FT_LOAD_TARGET_LIGHT no
 180         longer implies FT_LOAD_FORCE_AUTOHINT.

 238         * src/truetype/ttgload.c: Include FT_LIST_H.
 239         (load_truetype_glyph): Add composite subglyph index to a list;

 276
 277         [autofit] Add functions to get standard widths for writing systems.
 278
 279         We need the computed standard horizontal and vertical widths for the
 280         emboldening calculation.  This method provides a convenient way to
 281         extract it from writing-system-specific metrics structures, which
 282         all script definitions must implement.
 283
 284         * src/autofit/aftypes.h (AF_WritingSystem_GetStdWidthsFunc): New
 285         function type.

 310
 311         [autofit] Add stem-darkening properties.

 314
 315         * include/freetype/ftautoh.h: Document `no-stem-darkening' and
 316         `darkening-parameters'.
 317
 318         * src/autofit/afmodule.h: New fields `no_stem_darkening' and
 319         `darken_params'.
 320
 321         * src/autofit/afmodule.c (af_property_set, af_property_get):
 322         Handle them.
 323         (af_autofitter_init): Initialize them.
 324
 325 2015-11-02  Bungeman  <bungeman@gmail.com>
 326
 327         [ftfuzzer] Add support for multiple files (patch #8779).
 328
 329         Currently, libFuzzer only supports mutation of a single file.  We
 330         circumvent this problem by using an uncompressed tar archive as
 331         multiple-file input for the fuzzer.
 332
 333         This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing;
 334         a constructed tarball should contain a font file as the first
 335         element, and files to be attached as further elements.
 336
 337         * src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers.
 338         (archive_read_entry_data, parse_data): New functions.
 339         (LLVMFuzzerTestOneInput): Updated.
 340
 341         * src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom
 342         mutator for libFuzzer that can mutate tarballs in a sensible way.
 343

 826         [smooth] Faster alternative line renderer.
 827
 828         This implementation renders the entire line segment at once without
 829         subdividing it into scanlines.  The main speed improvement comes from
 830         reducing the number of divisions to just two per line segment, which
 831         is a bare minimum to calculate cell coverage in a smooth rasterizer.
 832         Notably, the progression from cell to cell does not itself require any
 833         divisions at all.  The speed improvement is more noticeable at larger
 834         sizes.
 835

1040         [sfnt] Better checks for invalid cmaps (2/2) (#46019).
1041
1042         While the current code in `FT_Get_Next_Char' correctly rejects
1043         out-of-bounds glyph indices, it can be extremely slow for malformed

1103         [sfnt] Improve handling of invalid SFNT table entries (#45987).
1104
1105         This patch fixes weaknesses in function `tt_face_load_font_dir'.
1106
1107         - It incorrectly assumed that valid tables are always at the
1108           beginning.  As a consequence, some valid tables after invalid
1109           entries (which are ignored) were never seen.
1110
1111         - Duplicate table entries (this is, having the same tag) were not
1112           rejected.
1113
1114         - The number of valid tables was sometimes too large, leading to
1115           access of invalid tables.
1116
1117         * src/sfnt/ttload.c (check_table_dir): Add argument to return number
1118         of valid tables.
1119         Add another tracing message.
1120         (tt_face_load_font_dir): Only allocate table array for valid
1121         entries as returned by `check_table_dir'.
1122         Reject duplicate tables and adjust number of valid tables
1123         accordingly.

1343 2015-09-04  Werner Lemberg  <wl@gnu.org>
1344
1345         [autofit] Redesign code ranges (1/2).
1346
1347         This patch introduces auxiliary code ranges that identify no-base
1348         characters; they refer to glyphs of a script that should be hinted
1349         without alignments to blue zones (mostly diacritics).
1350
1351         It also splits off ranges for fallback scripts that handle subscript
1352         and superscript characters not covered by OpenType features.  For
1353         example, this greatly helps improve the hinting of various phonetic
1354         alphabets, which contain a large amount characters that look like
1355         superscript glyphs.
1356
1357         Finally, code ranges are updated to Unicode 8.0, and enclosed
1358         characters are removed in general since they normally look better if
1359         they stay unhinted.
1360
1361         * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode
1362         8.0.
1363         Split off superscript-like and subscript-like glyphs into...
1364
1365         (af_latb_uniranges, af_latp_uniranges): ... these two new arrays.
1366
1367         (af_xxxx_nobase_uniranges): New arrays that hold no-base characters
1368         of the corresponding character ranges.

1534         [type42] Fix glyph access.
1535
1536         This is a severe bug: We've missed one level of indirection, as
1537         described in the Type 42 specification.  As a result, ftview
1538         sometimes showed incorrect glyphs for given glyph names, and even
1539         displayed `error 0x0006' (invalid argument!) in case the number of
1540         glyph indices differed between the Type 42 font and the embedded
1541         TTF.
1542
1543         Apparently, noone ever noticed it; this shows how much Type 42 fonts
1544         are in use...

1610
1611         [base] Fix `ft_corner_orientation'.
1612
1613         Remove casting from `FT_Long' to `FT_Int' that might change the sign
1614         of the return value and make it faster too.
1615
1616         * src/base/ftcalc.c (ft_corner_orientation): On 32-bit systems, stay
1617         with 32-bit arithmetic when safe. Use plain math on 64-bit systems.

1683 2015-07-31  Werner Lemberg  <wl@gnu.org>
1684
1685         Define FT_LONG_MAX.

1701
1702         * src/cff/cffgload.c (cff_slot_load): Use `htmx' table for advance
1703         width only.  Bug introduced 2015-04-10.
1704
1705 2015-07-09  Werner Lemberg  <wl@gnu.org>
1706
1707         Better support of user-supplied C++ namespaces.

1712
1713         for a rationale.
1714

1718         (FT_BEGIN_HEADER, FT_END_HEADER): Move macro calls to not enclose
1719         header files that contain FT_{BEGIN,END}_HEADER macros by
1720         themselves.
1721
1722         * src/autofit/aftypes.h [FT_DEBUG_AUTOFIT]: Include
1723         FT_CONFIG_STANDARD_LIBRARY_H earlier.

1730
1731         * include/freetype/internal/sfnt.h (TT_Get_Name_Func): New
1732         prototype.
1733         (SFNT_Interface, FT_DEFINE_SFNT_INTERFACE): New member `get_name'.
1734

1736
1737         * src/sfnt/sfobjs.c (tt_face_get_name): Tag it with `LOCAL_DEF'.

1763
1764         [base] Implement fast vector normalization.
1765
1766         The function uses Newton's iterations instead of dividing vector
1767         components by its length, which needs a square root. This is,
1768         literally, a bit less accurate but a lot faster.
1769
1770         * src/base/ftcalc.c (FT_Vector_NormLen): New function.
1771
1772 2015-06-28  Werner Lemberg  <wl@gnu.org>
1773
1774         * CMakeLists.txt: Always create `ftconfig.h'.
1775
1776         For non-UNIX builds, the file stays unmodified.  However, it's
1777         better to have the main configuration files at the same place
1778         regardless of the OS.

1808
1809         * src/tools/docmaker/utils.py (check_output): Add missing `\n'.
1810
1811 2015-06-26  Werner Lemberg  <wl@gnu.org>
1812
1813         * CMakeLists.txt: Select platform-dependent `ftdebug.c'.
1814
1815 2015-06-25  Werner Lemberg  <wl@gnu.org>
1816

1824 2015-06-25  Werner Lemberg  <wl@gnu.org>
1825
1826         Another adjustment to header locations.

1831
1832         Re-introduce the `freetype2' subdirectory for all FreeType header
1833         files after installation, and rename the `freetype2' subdirectory in

1886 2015-06-22  Werner Lemberg  <wl@gnu.org>
1887
1888         Fix Savannah bug #45097.
1889
1890         We no longer `pollute' the namespace of possible header file names;
1891         instead we move `ft2build.h' up by one level so that it gets
1892         installed in the default include directory (e.g.,
1893         /usr/local/include).  After this commit, only `ft2build.h' stays in
1894         the compiler's include path.
1895
1896         No visible changes for the user who follows the standard FreeType
1897         header inclusion rules.
1898
1899         * include/*: Move to ...

1925
1926         Make Jam support work again.
1927
1928         This is just very basic stuff and just a little bit tested on

2008         [truetype] Fix memory leak.
2009
2010         Problem reported by Grissiom <chaos.proton@gmail.com>; in
2011
2012           http://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html
2013
2014         there is an example code to trigger the bug.
2015
2016         * src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size'
2017         data before allocating again.  Bug most probably introduced four
2018         years ago in version 2.4.3.
2019
2020 2015-06-02  Werner Lemberg  <wl@gnu.org>
2021
2022         [raster] Add more tracing.
2023
2024         * src/raster/ftraster.c (FT_TRACE7) [_STANDALONE_]: Define.
2025         (Vertical_Sweep_Span, Vertical_Sweep_Drop, Horizontal_Sweep_Span,
2026         Horizontal_Sweep_Drop, Render_Glyph): Add tracing calls.
2027
2028 2015-06-01  Werner Lemberg  <wl@gnu.org>
2029
2030         [truetype] While tracing opcodes, show code position and stack.
2031
2032         * src/truetype/ttinterp.c: Change all existing TRACE7 calls to
2033         TRACE6.

2038
2039         [truetype] In GX, make private point numbers work correctly.
2040
2041         This is completely missing in Apple's documentation: If a `gvar'
2042         tuple uses private point numbers (this is, deltas are specified for
2043         some points only), the uncovered points must be interpolated for
2044         this tuple similar to the IUP bytecode instruction.  Examples that
2045         need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.
2046
2047         * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
2048         tt_handle_deltas): New functions.
2049         (TT_Vary_Get_Glyph_Deltas): Renamed to...
2050         (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the
2051         points and does no longer return an array of deltas.
2052         Add tracing information.
2053         Call `tt_handle_deltas' to interpolate missing deltas.
2054         Also fix a minor memory leak in case of error.
2055
2056         * src/truetype/ttgxvar.h: Updated.
2057
2058         * src/truetype/ttgload.c (TT_Process_Simple_Glyph,
2059         load_truetype_glyph): Updated.
2060
2061 2015-05-31  Werner Lemberg  <wl@gnu.org>
2062

2066
2067 2015-05-31  Werner Lemberg  <wl@gnu.org>
2068
2069         [truetype] Add tracing information to GX code.
2070

2081
2082 2015-05-24  Werner Lemberg  <wl@gnu.org>
2083
2084         [truetype] Fix commit from 2015-05-22.
2085
2086         * src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code
2087         with `TT_CONFIG_OPTION_SUBPIXEL_HINTING'.
2088
2089         Problem reported by Nikolaus Waxweiler <madigens@gmail.com>.
2090
2091 2015-05-23  Werner Lemberg  <wl@gnu.org>
2092
2093         [truetype] Fix return values of GETINFO bytecode instruction.
2094
2095         * src/truetype/ttinterp.h (TT_ExecContextRec): New fields
2096         `vertical_lcd' and `gray_cleartype'.
2097
2098         * src/truetype/ttgload.c (tt_loader_init): Initialize new fields.
2099         Change `symmetrical smoothing' to TRUE, since FreeType produces
2100         exactly this.
2101
2102         * src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit
2103         values for symmetrical smoothing, namely 11/18.
2104         Handle bits for vertical LCD subpixels (8/15) and Gray ClearType
2105         (12/19).
2106
2107 2015-05-23  Werner Lemberg  <wl@gnu.org>
2108
2109         [truetype] Minor.
2110
2111         * src/truetype/ttinterp.h (TT_ExecContext):
2112          s/subpixel/subpixel_hinting.
2113
2114         * src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.
2115
2116 2015-05-22  Werner Lemberg  <wl@gnu.org>
2117
2118         [truetype] Support selector index 3 of the INSTCTRL instruction.
2119
2120         This flag activates `native ClearType hinting', disabling backwards
2121         compatibility mode as described in Greg Hitchcocks whitepaper.  In
2122         other words, it enables unrestricted functionality of all TrueType
2123         instructions in ClearType.
2124
2125         * src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
2126         unconditionally.
2127         (tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of
2128         `GS.instruct_control' is active.
2129
2130         * src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.
2131         (Ins_GETINFO): Updated.
2132
2133         * docs/CHANGES: Document it.
2134
2135 2015-05-20  Werner Lemberg  <wl@gnu.org>
2136
2137         [truetype] Minor.
2138
2139         * src/truetype/ttinterp.h (SetSuperRound): Fix type of `GridPeriod'
2140         argument.
2141
2142 2015-05-17  Werner Lemberg  <wl@gnu.org>
2143
2144         [truetype] Fix loading of composite glyphs.
2145
2146         * src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
2147         ARGS_ARE_XY_VALUES flag is not set, handle argument values as
2148         unsigned.  I trust `ttx' (which has exactly such code) that it does
2149         the right thing here...
2150
2151         The reason that noone has ever noticed this bug is probably the fact
2152         that point-aligned subglyphs are rare, as are subglyphs with a
2153         number of points in the range [128;255], which is quite large (or
2154         even in the range [32768;65535], which is extremely unlikely).
2155
2156 2015-05-12  Chris Liddell  <chris.liddell@artifex.com>
2157
2158         [cff] Make the `*curveto' operators more tolerant.
2159
2160         * src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
2161         `vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
2162         pulling values off the stack until the stack is exhausted.
2163         Implicitly the stack must be a multiple (or for subtly different
2164         behaviour) a multiple plus a specific number of extra values deep.
2165         If that's not the case, enforce it (as the old code did).
2166
2167 2015-05-12  Chris Liddell  <chris.liddell@artifex.com>
2168
2169         [cff] fix incremental interface with new cff code.
2170
2171         * src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
2172         interface to retrieve glyph data for a SEAC, it be left to the
2173         incremental interface callback to apply the encoding to raw
2174         character index (as it was in the previous code).
2175
2176 2015-04-29  Alexei Podtelezhnikov <apodtele@gmail.com>
2177
2178         [autofit] Speed up IUP.
2179
2180         * src/autofit/afhints.c (af_iup_interp): Separate trivial snapping to
2181         the same position from true interpolation, use `scale' to reduce
2182         divisions.
2183
2184 2015-04-28  Werner Lemberg  <wl@gnu.org>
2185
2186         [cff] Use `name' table for PS name if we have a SFNT-CFF.
2187
2188         This follows the OpenType 1.7 specification.  See
2189
2190           http://tug.org/pipermail/tex-live/2015-April/036634.html

2193

2205
2206         [autofit] By default, enable warping code but switch off warping.
2207
2208         Suggested by Behdad.

2234
2235         * src/autofit/afhints.h (AF_HINTS_DO_WARP): Remove use of the no
2236         longer existing `_af_debug_disable_warper'.

2240         [AF_CONFIG_OPTION_USE_WARPER]: Add `AF_SCALER_FLAG_NO_WARPER' to the

2242
2243         * src/autofit/aftypes.h: Updated.

2305         [autofit] Make debugging stuff work again.
2306
2307         The interface to ftgrid was broken in the series of commits starting
2308         with

2334
2335         This commit allows `num_coords' to be larger or smaller than the
2336         number of available axes while selecting a design instance, either
2337         ignoring excess data or using defaults if data is missing.

2366
2367         Under normal circumstances we are usually close to the desired range
2368         of angle values, so that the remainder is not really necessary.
2369
2370         * src/base/fttrigon.c (FT_Angle_Diff): Use loops instead of remainder.
2371
2372         * src/autofit/aftypes.h (AF_ANGLE_DIFF): Ditto in the unused macro.

3049         [autofit] Fix potential memory leak.
3050
3051         While this doesn't show up with FreeType, exactly the same code
3052         leaks with ttfautohint's modified auto-hinter code (which gets used
3053         in a slightly different way).
3054
3055         It certainly doesn't harm since it is similar to already existing
3056         checks in the code for embedded arrays.
3057

3099         [raster] Fix Savannah bug #44022.
3100
3101         Add fallback for glyphs with degenerate bounding boxes.
3102
3103         If a glyph has only one very narrow feature, the bbox can end up
3104         with either the width or height of the bbox being 0, in which case
3105         no raster memory is allocated and no attempt is made to render the
3106         glyph.  This is less than ideal when the drop-out compensation in
3107         the rendering code would actually result in the glyph being
3108         rendered.
3109
3110         This problem can be observed with the `I' glyph (gid 47) in the
3111         Autodesk RomanS TrueType font.
3112
3113         * src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either
3114         dimension is zero to explicitly round up/down (instead of simply
3115         round).

3123         is no longer used to track years of modification changes.

3141         [autofit] Add embedded array of segments and edges.
3142
3143         Avoids multiple mallocs per typical glyphs.
3144
3145         With this and recent changes to avoid mallocs, the thread-safe
3146         stack-based loader is now as fast as the previous model that had one
3147         cached singleton.
3148
3149         * src/autofit/afhints.h (AF_SEGMENTS_EMBEDDED, AF_EDGES_EMBEDDED):

3194         [autofit] Reuse slot glyph loader.
3195
3196         No need to create a new glyph loader; we can reuse the one from
3197         `slot->internal->loader'.  It's hard to tell why it was written that
3198         way originally, but new code looks sound and correct to me, and
3199         avoids lots of allocations.
3200
3201         * src/autofit/afloader.c (af_loader_init): Change return type to
3202         `void'.
3203         Don't call `FT_GlyphLoader_New'.
3204         (af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.

3206         doesn't need copying of data.
3207

3209         Update prototype.

3214
3215         [autofit] Remove (unused) support for composite glyphs.
3216
3217         We never have to deal with composite glyphs in the autohinter, as
3218         those will be loaded into FORMAT_OUTLINE by the recursed
3219         `FT_Load_Glyph' function.
3220
3221         In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply
3222         FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies
3223         FT_LOAD_NO_HINTING:
3224
3225           /* resolve load flags dependencies */
3226
3227           if ( load_flags & FT_LOAD_NO_RECURSE )
3228             load_flags |= FT_LOAD_NO_SCALE         |
3229                           FT_LOAD_IGNORE_TRANSFORM;
3230
3231           if ( load_flags & FT_LOAD_NO_SCALE )
3232           {
3233             load_flags |= FT_LOAD_NO_HINTING |
3234                           FT_LOAD_NO_BITMAP;
3235
3236             load_flags &= ~FT_LOAD_RENDER;
3237           }
3238
3239         and as such the auto-hinter is never called.  Thus, the recursion in
3240         `af_loader_load_g' never actually happens.  So remove the depth
3241         counter as well.
3242
3243         * src/autofit/afloader.c (af_loader_load_g): Remove `depth'
3244         parameter.
3245         <FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.

3249
3250         [raster] Fix uninitialized memory access.
3251
3252         Apparently `ras.cProfile' might be uninitialized.  This will be the
3253         case if `ras.top == ras.cProfile->offset', as can be seen in
3254         `End_Profile'.  The overshoot code introduced in a change `Fix B/W
3255         rasterization of subglyphs with different drop-out modes.' (from
3256         2009-06-18) violated this, accessing `ras.cProfile->flags'
3257         unconditionally just before calling `End_Profile' (which then
3258         detected that `cProfile' is uninitialized and didn't touch it).
3259
3260         This was harmless, and was not detected by valgrind before because
3261         the objects were allocated on the `raster_pool', which was always
3262         initialized.  With recent change to allocate raster buffers on the
3263         stack, valgrind now reported this invalid access.
3264
3265         * src/raster/ftraster.c (Convert_Glyph): Don't access an
3266         uninitialized `cProfile'.

3269
3270         [smooth] Fix uninitialized memory access.
3271
3272         Looks like `ras.span_y' could always be used without initialization.
3273         This was never detected by valgrind before because the library-wide
3274         `raster_pool' was used for the worker object and `raster_pool' was
3275         originally zero'ed.  But subsequent reuses of it were using `span_y'
3276         uninitialized.  With the recent change to not use `render_pool' and
3277         allocate worker and buffer on the stack, valgrind now detects this
3278         uninitialized access.
3279
3280         * src/smooth/ftgrays.c (gray_raster_render): Initialize
3281         `ras.span_y'.

3294
3295         It's unused after the following commits:

3297           [raster] Allocate render pool for mono rasterizer on the stack.
3298           [raster] Remove 5-level gray AA mode from monochrome rasterizer.
3299
3300         The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
3301         serve, which is, to adjust the pool size.  But the pool is now
3302         allocated on the stack on demand.
3303

3308         [base] Do not reorder library->renderers upon use.
3309
3310         Instead of keeping `library->renderers' in a MRU order, just leave
3311         it as-is.  The MRU machinery wasn't thread-safe.
3312
3313         With this patch, rasterizing glyphs from different faces from

3315         (FT_Err_Cannot_Render_Glyph).
3316
3317         Easiest to see that crash was to add a `printf' (or otherwise let
3318         thread yield in FT_Throw with debugging enabled).

3390         [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
3391
3392         Previously the code had stipulation for using a per-TT_Size exec
3393         context if `size->debug' was true.  But there was no way that
3394         `size->debug' could *ever* be true.  As such, the code was always
3395         using the singleton `TT_ExecContext' that was stored in `TT_Driver'.
3396         This was, clearly, not threadsafe.

3424         [autofit] Allocate AF_Loader on the stack instead of AF_Module.
3425
3426         Stop sharing a global `AF_Loader'.  Allocate one on the stack during
3427         glyph load.
3428
3429         Right now this results in about 25% slowdown, to be fixed in a
3430         following commit.
3431
3432         With this patch loading glyphs from different faces from different
3433         threads doesn't immediately crash in the autohinting loader code.
