  48. 2010-02-10  Ken Sharp  <ken.sharp@artifex.com>
  49.  
  50.         Really fix Savannah bug #28678 (part 2).
  51.  
  52.         Since we consider `sbw' for the horizontal direction only, we still have
  53.         to synthesize vertical metrics if the user wants to use the vertical
  54.         writing direction.
  55.  
  56.         * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
  57.         (cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph):
  58.         Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is
  59.         set.
  60.  
  61. 2010-02-10  Ken Sharp  <ken.sharp@artifex.com>
  62.  
  63.         Really fix Savannah bug #28678 (part 1).
  64.  
  65.         After long discussion, we now consider the character width vector
  66.         (wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
  67.         direction only.  For example, if you are using the horizontal
  68.         writing direction, you get the horizontal and vertical components of
  69.         the advance width for this direction.  Note that OpenType and CFF fonts
  70.         don't have such a vertical component; instead, the GPOS table can be
  71.         used to generate two-dimensional advance widths (but this isn't
  72.         handled by FreeType).
  73.  
  74.         * include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add
  75.         `advance_v' field to hold the vertical component of the advance
  76.         value.
  77.  
  78.         * src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c
  79.         (cff_slot_load), src/type1/t1gload.c
  80.         (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c
  81.         (cid_load_glyph): Use it.
  82.  
  83. 2010-02-08  Werner Lemberg  <wl@gnu.org>
  84.  
  85.         * devel/ftoption.h [FT_CONFIG_OPTION_PIC]: Define.
  86.  
  87. 2010-02-04  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  88.  
  89.         Prevent NULL pointer dereference passed to FT_Module_Requester.
  90.  
  91.         * src/sfnt/sfdriver.c (sfnt_get_interface): Don't use `module'.
  92.         * src/psnames/psmodule.c (psnames_get_interface): Ditto.
  93.  
  94.         * src/cff/cffdrivr.c (cff_get_interface): Check NULL `driver'.
  95.         * src/truetype/ttdriver.c (tt_get_interface): Ditto.
  96.  
  97. 2010-01-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  98.  
  99.         Fix memory leaks in previous patch.
  100.  
  101.         * src/sfnt/sfobjs.c (sfnt_load_face): Don't overwrite the strings
  102.         allocated for face->root.family_name and style_name.
  103.  
  104. 2010-01-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  105.  
  106.         New parameters for FT_Open_Face() to ignore preferred family names.
  107.  
  108.         Preferred family names should be used for legacy systems that
  109.         can hold only a few faces (<= 4) for a family name. Suggested by
  110.         Andreas Heinrich.
  111.         http://lists.gnu.org/archive/html/freetype/2010-01/msg00001.html

  114.         FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY): Define.
  115.  
  116.         * src/sfnt/sfobjs.c (sfnt_load_face): Check the arguments and
  117.         ignore preferred family and subfamily names if requested.

  128.         (T1_Load_Glyph): Don't synthesize vertical metrics.
  129.  
  130. 2010-01-14  Werner Lemberg  <wl@gnu.org>
  131.  
  132.         Make FT_Set_Transform work if no renderer is available.
  133.  
  134.         * src/base/ftobjs.c (FT_Load_Glyph): Apply `standard' transformation
  135.         if no renderer is compiled into the library.
  136.  
  137. 2010-01-14  Werner Lemberg  <wl@gnu.org>
  138.  
  139.         Fix compilation warning.
  140.

  143.  
  144. 2010-01-11  Kwang Yul Seo  <skyul@company100.net>
  145.  
  146.         Provide inline assembly code for RVCT compiler.
  147.         This is Savannah patch #7059.
  148.  
  149.         * include/freetype/config/ftconfig.h (FT_MULFIX_ASSEMBLER,
  150.         FT_MulFix_arm) [__CC_ARM || __ARM_CC]: Define.
  151.  
  152. 2010-01-08  Ken Sharp  <ken.sharp@artifex.com>
  153.  
  154.         Fix Savannah bug #28521.
  155.  
  156.         Issue #28226 involved a work-around for a font which used the
  157.         `setcurrentpoint' operator in an invalid way; this operator is only
  158.         supposed to be used with the result of OtherSubrs, and the font used
  159.         it directly.  The supplied patch removed the block of code which
  160.         checked this usage entirely.
  161.  
  162.         This turns out to be a Bad Thing.  If `setcurrentpoint' is being
  163.         used correctly it should reset the flex flag in the decoder.  If we
  164.         don't do this then the flag never gets reset and we omit any further
  165.         contours from the glyph (at least until we close the path or
  166.         similar).
  167.  
  168.         * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
  169.         <op_setcurrentpoint>: Handle `flex_state' correctly.
  170.  
  171. 2010-01-05  Werner Lemberg  <wl@gnu.org>
  172.  
  173.         Apply reports from clang static analyzer.
  174.  
  175.         * src/lzw/ftlzw.c (ft_lzw_file_init), src/base/ftstroke.c
  176.         (FT_Stroker_ParseOutline), src/base/ftsynth.c
  177.         (FT_GlyphSlot_Embolden): Remove dead code.
  178.  
  179.         * src/base/ftpatent.c (_tt_check_patents_in_table): Initialize
  180.         `offset_i' and `length_i'.
  181.  
  182. 2010-01-05  Ralph Giles  <giles@ghostscript.com>
  183.  
  184.         Enable the incremental font interface by default.
  185.  
  186.         Ghostscript requires the incremental font interface for handling
  187.         some Postscript documents.  It is moving to using FreeType as its
  188.         primary renderer; supporting this in the default build makes it
  189.         Ghostscript to be linked against the system FreeType when one is
  190.         available.
  191.  
  192.         * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):
  193.         Uncomment.
  194.  
  195. 2010-01-05  Werner Lemberg  <wl@gnu.org>
  196.  
  197.         Fix Savannah bug #28395.
  198.  
  199.         * src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c
  200.         (T1_Loada_Glyph): Don't check `num_glyphs' if incremental interface
  201.         is used.
  202.  
  203. 2010-01-05  Ken Sharp  <ken.sharp@artifex.com>
  204.  
  205.         Make Type 1 `seac' operator work with incremental interface.
  206.         This fixes Savannah bug #28480.
  207.  
  208.         * src/psaux/t1decode.c (t1operator_seac): Don't check `glyph_names'
  209.         if incremental interface is used.
  210.  
  211. 2010-01-04  Ken Sharp  <ken.sharp@artifex.com>
  212.  
  213.         Make incremental interface work with TrueType fonts.
  214.         This fixes Savannah bug #28478.
  215.  
  216.         * src/truetype/ttgload.c (load_truetype_glyph): Don't check
  217.         `glyf_offset' if incremental interface is used.
  218.  
  219. 2009-12-31  Lars Abrahamsson  <wonko@opera.com>
  220.  
  221.         Make compilation with FT_CONFIG_OPTION_PIC work again.
  222.  
  223.         * src/base/ftglyph.c (FT_Glyph_To_Bitmap) [FT_CONFIG_OPTION_PIC]:
  224.         Declare `library' for FT_BITMAP_GLYPH_CLASS_GET.
  225.  
  226.         * src/base/ftinit.c (ft_destroy_default_module_classes,
  227.         ft_create_default_module_classes): Use proper casts (needed for C++
  228.         compilation).
  229.  
  230.         * src/sfnt/ttcmap.c (tt_cmap13_class_rec): Use FT_DEFINE_TT_CMAP.
  231.  
  232. 2009-12-22  Marc Kleine-Budde  <mkl@pengutronix.de>
  233.  
  234.         Make freetype-config aware of $SYSROOT.
  235.         This is Savannah patch #7040.
  236.  
  237.         * builds/unix/freetype-config.in: Decorate with ${SYSROOT} where
  238.         appropriate.
  239.  
  240. 2009-12-20  Werner Lemberg  <wl@gnu.org>
  241.  
  242.         Fix compiler warning.
  243.         Reported by Sean.
  244.  
  245.         * src/base/ftdbgmem.c [!FT_DEBUG_MEMORY]: ANSI C doesn't like empty
  246.         source files; however, some compilers warn about an unused variable
  247.         declaration.  This is now replaced with a typedef.
  248.  
  249. 2009-12-18  Werner Lemberg  <wl@gnu.org>
  250.  
  251.         Fix Savannah bug #28320.
  252.  
  253.         There exist corrupt, subsetted fonts (embedded in PDF files) which
  254.         contain a private dict that ends with an unterminated floating point
  255.         number (no operator following).  We now ignore this error (as
  256.         acrobat does).
  257.  
  258.         * src/cff/cffparse.c (cff_parser_run): Don't emit a syntax error for
  259.         unterminated floating point numbers.
  260.  
  261. 2009-12-16  Werner Lemberg  <wl@gnu.org>
  262.  
  263.         Really fix compiler warnings.
  264.         Reported by Sean.
  265.  
  266.         * src/truetype/ttgxvar.c (GX_PT_POINTS_ARE_WORDS,
  267.         GX_PT_POINT_RUN_COUNT_MASK): Convert enum values to macros.
  268.  
  269. 2009-12-16  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  270.  
  271.         Improve configure.raw to copy some options from CFLAGS to LDFLAGS.
  272.         The linker of Mac OS X 10.6 is sensitive to the architecture.  If
  273.         the architectures are specified explicitly for the C compiler, the
  274.         linker requires the architecture specifications too.
  275.  
  276.         * builds/unix/configure.raw: Replace `-isysroot' option parser by
  277.         more generic argument parser.
  278.  
  279. 2009-12-15  Werner Lemberg  <wl@gnu.org>
  280.  
  281.         Fix compiler warnings.
  282.         Reported by Sean.
  283.  
  284.         * src/truetype/ttgxvar.c (ft_var_readpackeddeltas): Fix counter data
  285.         type.
  286.  
  287. 2009-12-14  Ken Sharp  <ken.sharp@artifex.com>
  288.  
  289.         Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
  290.         This fixes Savannah bug #28226.
  291.  
  292.         At least two wild PostScript files of unknown provenance contain
  293.         Type 1 fonts, apparently converted from TrueType fonts in earlier
  294.         PDF versions of the files, which use the `setcurrentpoint' operator
  295.         inappropriately.
  296.  
  297.         FreeType currently throws an error in this case, but Ghostscript and
  298.         Adobe Distiller both accept the fonts and ignore the problem.  This
  299.         commit #ifdefs out the check so PostScript interpreters using
  300.         FreeType can render these files.
  301.  
  302.         The specification says `setcurrentpoint' should only be used to set
  303.         the point after a `Subr' call, but these fonts use it to set the
  304.         initial point to (0,0).  Unnecessarily so, as they correctly use an
  305.         `hsbw' operation which implicitly sets the initial point.
  306.  
  307.         * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
  308.         <op_setcurrentpoint>: Comment out code.
  309.  
  310. 2009-12-14  Bram Tassyns  <bramt@enfocus.be>
  311.  
  312.         Fix parsing of /CIDFontVersion.
  313.         This fixes Savannah bug #28287.
  314.  
  315.         * src/cid/cidtoken.h: `cid_version' in CID_FaceInfoRec (in
  316.         t1tables.h) is of type FT_Fixed.
  317.  
  318. 2009-12-14  Werner Lemberg  <wl@gnu.org>
  319.  
  320.         Trace glyph index in CID module.
  321.         Suggested in Savannah patch #7023.

  333. 2009-11-25  John Tytgat  <John.Tytgat@esko.com>
  334.  
  335.         Better handling of start of `eexec' section.
  336.         This fixes Savannah bug #28090.
  337.  
  338.         * src/type1/t1parse.c (T1_Get_Private_Dict): Skip all whitespace
  339.         characters before start of `eexec' section.
  340.  
  341. 2009-11-20  Werner Lemberg  <wl@gnu.org>

  624.         [BDF] Modify hash API to take size_t value instead of void *.
  625.  
  626.         The hash API in BDF driver is designed to be generic, it takes
  627.         void * typed data.  But BDF driver always gives an unsigned long
  628.         integer (the index to a property).  To reduce non-essential
  629.         casts from unsigned long to void* and from void* to unsigned
  630.         long, the hash API is changed to take size_t integer.
  631.         The issue of incompatible cast between unsigned long and void*
  632.         on LLP64 platform is reported by NightStrike from MinGW-Win64
  633.         project.  See

  643.         (_bdf_set_default_spacing): Get the name length of the face by
  644.         size_t variable, with a cut-off at 256.
  645.         (bdf_get_property): Get the property id by size_t variable to
  646.         reduce the casts between 32-bit prop ID & hashnode->data during
  647.         simple copying.
  648.         (_bdf_add_property): Ditto.
  649.         (_bdf_parse_start): Calculate the index to the property array

  678.  
  679.         Improve vertical metrics calculation (Savannah bug #27364).
  680.  
  681.         The calculation of `vertBearingX' is not defined in the OTF font
  682.         spec so FreeType does a `best effort' attempt.  However, this value
  683.         is defined in the PDF and PostScript specs, and that algorithm is
  684.         better than the one FreeType currently uses:
  685.  
  686.           FreeType: Use the middle of the bounding box as the X coordinate
  687.                     of the vertical origin.
  688.  
  689.           Adobe PDF spec: Use the middle of the horizontal advance vector as
  690.                           the X coordinate of the vertical origin.
  691.  
  692.         FreeType's algorithm goes wrong if you have a really small glyph
  693.         (like the full-width, circle-like dot at the end of the sentence, as
  694.         used in CJK scripts) with large bearings.  With the FreeType
  695.         algorithm this dot gets centered on the baseline; with the PDF
  696.         algorithm it gets the correct location (in the top right).  Note
  697.         that this is a serious issue, it's like printing the dot at the end
  698.         of a Roman sentence at the center of the textline instead of on the
  699.         baseline like it should. So i believe the PDF spec's algorithm
  700.         should be used in FreeType as well.
  701.  
  702.         The `vertBearingY' value for such small glyphs is also very strange
  703.         if no `vmtx' information is present, since the height of the bbox is
  704.         not representable for the height of the glyph visually (the
  705.         whitespace up to the baseline is part of the glyph).  The fix also
  706.         includes some code for a better estimate of `vertBearingY'.
  707.  
  708.         * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
  709.         is now calculated as described by the Adobe PDF Spec.  Estimate for
  710.         `vertBearingY' now works better for small glyphs completely above or
  711.         below the baseline into account.
  712.  
  713.         * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
  714.         calculated as described by the Adobe PDF Spec.  Vertical metrics
  715.         information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
  716.         was not defined.
  717.  
  718.         * src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
  719.         now calculated as described by the Adobe PDF Spec.

  1951.         * src/smooth/ftsmooth.c (ft_smooth_render_generic): Improve
  1952.         the check for too large glyph.  Replace the pair of `pitch' and
  1953.         `height' by the pair of `width' and `height'.  `pitch' cannot
  1954.         be greater than `height'.  The required is checking the product

  2051.  
  2052.         * configure: If `configure' is executed outside of the source tree,

  2062.         the top source directory.  Thus the configure script in the top

  2098.  
  2099.         Use 16.16 format while parsing Type 1 charstrings.
  2100.         This fixes Savannah bug #26867.
  2101.  
  2102.         Previously, only integers have been used which can lead to serious
  2103.         rounding errors.
  2104.  
  2105.         However, fractional values are only used internally; after the
  2106.         charstrings (of either Type 1 or 2) have been processed, the
  2107.         resulting coordinates get rounded to integers currently -- before
  2108.         applying scaling.  This should be fixed; at the same time a new load
  2109.         flag should be introduced, to be used in combination with
  2110.         FT_LOAD_NO_SCALE, which indicates that font units are returned in
  2111.         16.16 format.  Similarly, the incremental interface should be
  2112.         extended to allow fractional values for metrics.
  2113.

  2120.         (t1_build_add_point): Always convert fixed to integer.
  2121.         * src/psaux/t1decode.c (t1_decoder_parse_charstrings):
  2122.         Use 16.16 format everywhere (except for large integers followed by a
  2123.         `div').
  2124.         [CAN_HANDLE_NON_INTEGRAL_T1_OPERANDS]: Remove #ifdef and activate
  2125.         code uncoditionally.
  2126.         Add support for random numbers and update remaining code
  2127.         accordingly; this should work now.

  2215. 2009-06-18  Werner Lemberg  <wl@gnu.org>
  2216.  
  2217.         Fix B/W rasterization of subglyphs with different drop-out modes.
  2218.  
  2219.         Normally, the SCANMODE instruction (if present) to set the drop-out
  2220.         mode in a TrueType font is located in the `prep' table only and thus
  2221.         valid for all glyphs.  However, there are fonts like `pala.ttf'
  2222.         which additionally contain this instruction in the hinting code of
  2223.         some glyphs (but not all).  As a result it can happen that a
  2224.         composite glyph needs multiple drop-out modes for its subglyphs
  2225.         since the rendering state gets reset for each subglyph.
  2226.  
  2227.         FreeType collects the hinted outlines from all subglyphs, then it
  2228.         sends the data to the rasterizer.  It also sends the drop-out mode
  2229.         -- after hinting has been applied -- and here is the error: It sends
  2230.         the drop-out mode of the last subglyph only; drop-out modes of all
  2231.         other subglyphs are lost.
  2232.  
  2233.         This patch fixes the problem; it adds a second, alternative
  2234.         mechanism to pass the drop-out mode: For each contour, the
  2235.         rasterizer now checks the first `tags' array element.  If bit 2 is
  2236.         set, bits 5-7 contain the contour's drop-out mode, overriding the
  2237.         global drop-out mode.
  2238.  
  2239.         * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.
  2240.  
  2241.         * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in
  2242.         `tags[0]'.
  2243.  
  2244.         * src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):
  2245.         Use bits 3-5 instead of 0-2.
  2246.         (New_Profile): Set the drop-out mode in the profile's `flags' field.
  2247.         (Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
  2248.         necessary.
  2249.         (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
  2250.         Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out
  2251.         mode.
  2252.  
  2253. 2009-06-16  Werner Lemberg  <wl@gnu.org>
  2254.  
  2255.         Improve scan conversion rules 4 and 6.
  2256.  
  2257.         Two new constraints are introduced to better identify a `stub' -- a
  2258.         concept which is only vaguely described in the OpenType
  2259.         specification.  The old code was too rigorous and suppressed more
  2260.         pixel than it should.
  2261.  
  2262.           . The intersection of the two profiles with the scanline is less
  2263.             than a half pixel.  Code related to this was already present in
  2264.             the sources but has been commented out.
  2265.  
  2266.           . The endpoint of the original contour forming a profile has a
  2267.             distance (`overshoot') less than half a pixel to the scanline.
  2268.  
  2269.         Note that the two additional conditions fix almost all differences
  2270.         to the Windows rasterizer, but some problematic cases remain.
  2271.  
  2272.         * src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New
  2273.         macros for the `flags' field in the `TProfile' structure.
  2274.         (IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros.
  2275.         (New_Profile, End_Profile): Pass overshoot flag as an argument and
  2276.         set it accordingly.
  2277.         Update callers.
  2278.         (Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement the two new
  2279.         constraints.
  2280.  
  2281. 2009-06-11  Werner Lemberg  <wl@gnu.org>
  2282.  
  2283.         Increase precision for B/W rasterizer.
  2284.  
  2285.         * src/raster/ftraster.c (Set_High_Precision): Add two more bits to
  2286.         the precision.  This corrects rendering of some small glyphs, for
  2287.         example, glyph `xi' in verdana.ttf at 13 ppem.  Testing with ftbench
  2288.         on my GNU/Linux box I don't see a performance degradation.

  3129.  
  3130. 2009-03-09  Alexey Kryukov  <anagnost@yandex.ru>
  3131.  
  3132.         Fix handling of EBDT formats 8 and 9 (part 2).
  3133.  
  3134.         This patch fixes the following problems in ttsbit0.c:
  3135.  
  3136.         . Bitmaps for compound glyphs were never allocated.
  3137.  
  3138.         . `SBitDecoder' refused to load metrics if some other metrics have
  3139.           already been loaded.  This condition certainly makes no sense for
  3140.           recursive calls, so I've just disabled it.  Another possibility
  3141.           would be resetting `decoder->metrics_loaded' to false before
  3142.           loading each composite component.  However, we must restore the
  3143.           original metrics after finishing the recursion; otherwise we can
  3144.           get a misaligned glyph.
  3145.  
  3146.         . `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',
  3147.           causing some glyph components to be shifted too far to the right
  3148.           (especially noticeable for small sizes).
  3149.  
  3150.         Note that support for grayscale bitmaps (not necessarily compound) is
  3151.         completely broken in ttsbit0.c.
  3152.  
  3153.         * src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.
  3154.         (tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case
  3155.         of `h == height'.
  3156.         (tt_sbit_decoder_load_compound): Reset metrics after loading
  3157.         components.
  3158.         Allocate bitmap.
  3159.  
  3160. 2009-03-09  Werner Lemberg  <wl@gnu.org>
  3161.  
  3162.         * builds/unix/configure.raw (version_info): Set to 9:20:3.

  3164. 2009-03-03  David Turner  <david@freetype.org>
  3165.  
  3166.         Protect SFNT kerning table parser against malformed tables.
  3167.  
  3168.         This closes Savannah BUG #25750.
  3169.  
  3170.         * src/sfnt/ttkern.c (tt_face_load_kern, tt_face_get_kerning): Fix a
  3171.         bug where a malformed table would be successfully loaded but later
  3172.         crash the engine during parsing.
  3173.  
  3174. 2009-03-03  David Turner  <david@freetype.org>
  3175.

  3181.  
  3182. 2009-03-03  David Turner  <david@freetype.org>
  3183.  
  3184.         Remove ABI-breaking field in public PS_InfoFontRec definition.
  3185.  
  3186.         Instead, we define a new internal PS_FontExtraRec structure to
  3187.         hold the additional field, then place it in various internal
  3188.         positions of the corresponding FT_Face derived objects.
  3189.  
  3190.         * include/freetype/t1tables.h (PS_FontInfoRec): Remove the
  3191.         `fs_type' field from the public structure.

  3202.         * src/type1/t1load.c (t1_load_keyword): Handle

  3204.  
  3205.         * include/freetype/internal/services/svpsinfo.h (PsInfo service):
  3206.         Add `PS_GetFontExtraFunc' function typedef.

  3221.  
  3222.         Fix handling of EBDT formats 8 and 9.
  3223.  
  3224.         The main cycle in `blit_sbit' makes too many iterations: it actually
  3225.         needs the count of lines in the source bitmap rather than in the
  3226.         target image.
  3227.  
  3228.         * src/sfnt/ttsbit.c (blit_sbit) [FT_CONFIG_OPTION_OLD_INTERNALS]:

  3535.         FT_USE_MODULE declares things as:
  3536.  
  3537.           extern const FT_Module_Class
  3538.  
  3539.         (or similar for C++).  However, the actual types of the variables
  3540.         being declared are often different, e.g., FT_Driver_ClassRec or
  3541.         FT_Renderer_Class.  (Some are, indeed, FT_Module_Class.)
  3542.  
  3543.         This works with most C compilers (since those structs begin with an
  3544.         FT_Module_Class struct), but technically it's undefined behavior.
  3545.  
  3546.         To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
  3547.         paragraph 2:
  3548.  
  3549.           All declarations that refer to the same object or function shall
  3550.           have compatible type; otherwise, the behavior is undefined.
  3551.  
  3552.         (And they are not compatible types.)
  3553.  
  3554.         Most C compilers don't reject (or even detect!) code which has this
  3555.         issue, but the GCC LTO development branch compiler does.  (It
  3556.         outputs the types of the objects while generating .o files, along
  3557.         with a bunch of other information, then compares them when doing the
  3558.         final link-time code generation pass.)

  3602.         out of the box.
  3603.  
  3604. 2008-12-17  Werner Lemberg  <wl@gnu.org>
  3605.

  3613.  
  3614.         Generalize the concept of `tricky' fonts by introducing
  3615.         FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
  3616.         engine is necessary for correct rendering.
  3617.  
  3618.         At the same time, slightly modify the behaviour of tricky fonts:
  3619.         FT_LOAD_NO_HINTING is now ignored.  To really force raw loading
  3620.         of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
  3621.         FT_LOAD_NO_AUTOHINT must be used.
  3622.  
  3623.         Finally, tricky TrueType fonts always use the bytecode interpreter
  3624.         even if the patented code is used.
  3625.  
  3626.         * include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY):
  3627.         New macros.
  3628.  
  3629.         * src/truetype/ttdriver.c (Load_Glyph): Handle new load flags
  3630.         semantics as described above.

  3633.         code of ...
  3634.         (tt_face_init): This function, now simplified and updated to new
  3635.         semantics.
  3636.  
  3637.         * src/base/ftobjs.c (FT_Load_Glyph): Don't use autohinter for tricky
  3638.         fonts.
  3639.  
  3640.         * docs/CHANGES: Document it.
  3641.  
  3642. 2008-12-09  Werner Lemberg  <wl@gnu.org>
  3643.  
  3644.         Really fix Savannah bug #25010: An SFNT font with neither outlines
  3645.         nor bitmaps can be considered as containing space `glyphs' only.
  3646.  
  3647.         * src/truetype/ttpload.c (tt_face_load_loca): Handle the case where
  3648.         a `glyf' table is missing.
  3649.  
  3650.         * src/truetype/ttgload.c (load_truetype_glyph): Abort if we have no
  3651.         `glyf' table but a non-zero `loca' entry.
  3652.         (tt_loader_init): Handle missing `glyf' table.

  3660.  
  3661.         * src/autofit/aflatin.c (af_latin_uniranges): Add more ranges.  This
  3662.         fixes Savannah bug #21190 which also provides a basic patch.
  3663.

  3665.  
  3666.         * include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): Use value
  3667.         0x100 instead of 0x10000; the latter value is already occupied by
  3668.         FT_LOAD_TARGET_LIGHT.  Bug reported by James Cloos.
  3669.  
  3670.  
  3671.         Handle SFNT with neither outlines nor bitmaps.  This fixes Savannah

  3706.         in the /BlendDesignMap space).

  3931.  
  3932.         * src/cff/cffgload.c (cff_slot_load): Map CID 0 to GID 0.  This
  3933.         fixes Savannah bug #24430.
  3934.  
  3935. 2008-10-02  Werner Lemberg  <wl@gnu.org>
  3936.  
  3937.         * builds/freetype.mk (BASE_H): Rename to...
  3938.         (INTERNAL_H): This.
  3939.         (FREETYPE_H): Updated.
  3940.         * src/base/rules.mk: (BASE_OBJ_S, OBJ_DIR/%.$O): Add BASE_H.

  3948.  
  3949.         * src/base/ftbase.h: New file to declare the private utility
  3950.         functions shared by the sources of base modules.  Currently,
  3951.         `ft_lookup_PS_in_sfnt' and `open_face_from_buffer' are declared to
  3952.         share between ftobjs.c and ftmac.c.
  3953.  
  3954.         * src/base/rule.mk: Add ftbase.h.
  3955.  
  3956.         * src/base/ftobjs.c: Include ftbase.h.
  3957.         (memory_stream_close): Build on any platform when old MacOS font
  3958.         support is enabled.
  3959.         (new_memory_stream): Ditto.
  3960.         (open_face_from_buffer): Build on any platform when old MacOS font
  3961.         support is enabled.  The counting of the face in a font file is
  3962.         slightly different between Carbon-dependent parser and Carbon-free
  3963.         parser.  They are merged with the platform-specific conditional.
  3964.         (ft_lookup_PS_in_sfnt): Ditto.
  3965.  
  3966.         * src/base/ftmac.c: Include ftbase.h.
  3967.         (memory_stream_close): Removed.
  3968.         (new_memory_stream): Ditto.
  3969.         (open_face_from_buffer): Removed.  Use the implementation in
  3970.         ftobjs.c.
  3971.         (ft_lookup_PS_in_sfnt): Ditto.
  3972.  
  3973. 2008-10-02  Werner Lemberg  <wl@gnu.org>
  3974.  
  3975.         * src/sfnt/sfobjs.c (sfnt_load_face): `psnames_error' is only needed
  3976.         if TT_CONFIG_OPTION_POSTSCRIPT_NAMES is defined.
  3977.  
  3978. 2008-10-01  Werner Lemberg  <wl@gnu.org>
  3979.

  3985.         Reported by Graham Asher.
  3986.  
  3987. 2008-09-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  3988.  
  3989.         * src/base/rules.mk: Add conditional source to BASE_SRC, for `make
  3990.         multi' on Mac OS X.  If the macro $(ftmac_c) is defined,
  3991.         $(BASE_DIR)/$(ftmac_c) is added to BASE_SRC.  In a normal build, the
  3992.         lack of ftmac.c in BASE_SRC is not serious because ftbase.c includes
  3993.         ftmac.c.
  3994.         * builds/unix/unix-def.in: Add a macro definition of $(ftmac_c).
  3995.         * builds/unix/configure.raw: Add procedure to set up appropriate
  3996.         value of $(ftmac_c) with the consideration of the availability of
  3997.         Carbon framework.
  3998.  
  3999. 2008-09-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  4000.  
  4001.         * src/base/Jamfile: Add target for multi build by jam on Mac OS X.
  4002.         * src/base/ftobjs.c (FT_New_Face): Fix the condition to include this
  4003.         function for MPW building.  It is synchronized the condition to
  4004.         include ftmac.c source into ftbase.c.
  4005.  
  4006. 2008-09-22  Werner Lemberg  <wl@gnu.org>
  4007.  
  4008.         * src/cff/cffgload.c (CFF_Operator, cff_argument_counts,
  4009.         cff_decoder_parse_charstrings): Handle (invalid)
  4010.         `callothersubr' and `pop' instructions.

  4014.         Fix Savannah bug #24307.
  4015.  
  4016.         * include/freetype/internal/t1types.h (CID_FaceRec),
  4017.         src/type42/t42types.h (T42_FaceRec): Comment out `afm_data'.
  4018.  
  4019. 2008-09-21  Werner Lemberg  <wl@gnu.org>
  4020.  
  4021.         * src/smooth/ftgrays.c (gray_raster_render): Don't dereference
  4022.         `target_map' if FT_RASTER_FLAG_DIRECT is set.  Problem reported by
  4023.         Stephan T. Lavavej <stl@nuwen.net>.
  4024.  
  4025. 2008-09-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  4026.  
  4027.         * src/otvalid/Jamfile: Add missing target `otvmath' for multi build
  4028.         by jam.
  4029.         * src/sfnt/Jamfile: Add missing target `ttmtx' for multi build by
  4030.         jam.
  4031.  
  4032. 2008-09-20  Werner Lemberg  <wl@gnu.org>
  4033.  
  4034.         * src/smooth/ftgrays.c (gray_find_cell): Fix threshold.  The values
  4035.         passed to this function are already `normalized'.  Problem reported
  4036.         by Stephan T. Lavavej <stl@nuwen.net>.
  4037.  
  4038.         * docs/CHANGES: Document it.
  4039.  
  4040. 2008-09-20  Werner Lemberg  <wl@gnu.org>
  4041.  
  4042.         * src/base/ftoutln.c: Include FT_INTERNAL_DEBUG_H.
  4043.         (FT_Outline_Decompose): Decorate with tracing messages.
  4044.  
  4045.         * src/smooth/ftgrays.c [DEBUG_GRAYS]: Replace with
  4046.         FT_DEBUG_LEVEL_TRACE.
  4047.         [_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: Include stdio.h and
  4048.         stdarg.h.
  4049.  
  4050.         (FT_TRACE) [_STANDALONE_]: Remove.
  4051.         (FT_Message) [_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: New function.
  4052.         (FT_TRACE5, FT_TRACE7) [_STANDALONE_]: New macros.
  4053.         (FT_ERROR) [_STANDALONE_]: Updated.
  4054.  
  4055.         (gray_hline) [FT_DEBUG_LEVEL_TRACE]: Fix condition.
  4056.         Use FT_TRACE7.
  4057.         (gray_dump_cells): Make it `static void'.
  4058.         (gray_convert_glyph): Use FT_TRACE7.
  4059.  
  4060.         (FT_Outline_Decompose) [_STANDALONE_]: Synchronize with version in
  4061.         ftoutln.c.
  4062.  
  4063.         * src/base/ftadvanc.c (FT_Get_Advance, FT_Get_Advances): Use
  4064.         FT_ERROR_BASE.
  4065.  
  4066.         * docs/formats.txt: Updated.

  4069.  
  4070.         * src/base/ftmac.c: Import sfnt-wrapped Type1 and sfnt-wrapped
  4071.         CID-keyed font support.
  4072.         * builds/mac/ftmac.c: Ditto.

  4074. 2008-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  4075.  
  4076.         * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Fix double free bug in
  4077.         sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support code.
  4078.         `open_face_from_buffer' frees the passed buffer if it cannot open a
  4079.         face from the buffer, so the caller must not free it.
  4080.  
  4081. 2008-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  4082.  
  4083.         * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Add initial support
  4084.         for sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font.

  4086.         table in sfnt table directory.  It is used before loading TrueType
  4087.         font driver.
  4088.  
  4089.         * docs/CHANGES: Add note about the current status of sfnt-wrapped
  4090.         Type1 and sfnt-wrapped CID-keyed font support.
  4091.  
  4092. 2008-09-18  Werner Lemberg  <wl@gnu.org>
  4093.  
  4094.         * src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for
  4095.         orthogonality (ft_free and ft_sfree could belong to different memory
  4096.         pools).  This fixes Savannah bug #24297.
  4097.  
  4098. 2008-09-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  4099.  
  4100.         * src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined
  4101.         in ttags.h instead of numerical value 0x4F54544FL.
  4102.  
  4103. 2008-09-16  Werner Lemberg  <wl@gnu.org>
  4104.  
  4105.         * src/cff/cffgload.h, src/cff/cffgload.c
  4106.         (cff_decoder_set_width_only): Eliminate function call.
  4107.  
  4108. 2008-09-15  George Williams  <gww@silcom.com>
  4109.  
  4110.         Fix Savannah bug #24179, reported by Bram Tassyns.
  4111.  
  4112.         * src/type1/t1load.c (mm_axis_unmap, T1_Get_MM_Var): Fix computation
  4113.         of default values.
  4114.  
  4115. 2008-09-15  Werner Lemberg  <wl@gnu.org>
  4116.  
  4117.         * src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index'
  4118.         and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to
  4119.         prevent unconditional definition.  This fixes Savannah bug #24241.
  4120.  
  4121.         * src/psnames/pstables.h: Regenerated.
  4122.  
  4123. 2008-09-13  Werner Lemberg  <wl@gnu.org>

  4127.         beautifying.
  4128.  
  4129.         * include/freetype/ftadvanc.h, include/freetype/ftgasp.h,
  4130.         include/freetype/ftlcdfil.h: Protect against FreeType 1.
  4131.         Some other minor fixes.
  4132.  
  4133.         * devel/ftoption.h: Synchronize with
  4134.         include/freetype/config/ftoption.h.
  4135.  
  4136. 2008-09-11  Werner Lemberg  <wl@gnu.org>
  4137.  
  4138.         * src/base/ftbase.c: Include ftadvanc.c.
  4139.  
  4140. 2008-09-11  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  4141.  
  4142.         * builds/unix/ftconfig.in: Duplicate the cpp computation of
  4143.         FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.
  4144.         (FT_USE_AUTOCONF_SIZEOF_TYPES): New macro.  If defined, the cpp
  4145.         computation is disabled and the statically configured sizes are
  4146.         used.  This fixes Savannah bug #21250.
  4147.  
  4148.         * builds/unix/configure.raw: Add the checks to compare the cpp
  4149.         computation results of the bit length of int and long versus the
  4150.         sizes detected by running `configure'.  If the results are
  4151.         different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the
  4152.         results.
  4153.         New option --{enable|disable}-biarch-config is added to define or
  4154.         undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.
  4155.  
  4156. 2008-09-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  4157.  
  4158.         * builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or
  4159.         ApplicationService framework is missing.  Although this value is not
  4160.         used in building of FreeType2, it is written in `freetype2.pc' and
  4161.         `freetype-config'.
  4162.  
  4163. 2008-09-01  david turner  <david@freetype.org>
  4164.  
  4165.         * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap
  4166.         index to mean `use default cached FT_Face's charmap'.  This fixes
  4167.         Savannah bug #22625.
  4168.         * include/freetype/ftcache.h: Document it.
  4169.  
  4170.  
  4171.         Make FT_MulFix an inlined function.  This is done to speed up
  4172.         FreeType a little (on x86 3% when loading+hinting, 10% when
  4173.         rendering, ARM savings are more important though).  Disable this by
  4174.         undefining FT_CONFIG_OPTION_INLINE_MULFIX.
  4175.  
  4176.         Use of assembler code can now be controlled with
  4177.         FT_CONFIG_OPTION_NO_ASSEMBLER.
  4178.  
  4179.         * include/freetype/config/ftconfig.h, builds/unix/ftconfig.in

  4184.         [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MULFIX_ASSEMBLER): New macro
  4185.         which is defined to the platform-specific assembler implementation
  4186.         of FT_MulFix.
  4187.         [FT_CONFIG_OPTION_INLINE_MULFIX && FT_MULFIX_ASSEMBLER]
  4188.         (FT_MULFIX_INLINED): New macro.

  4194.  
  4195.         * src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and
  4196.         FT_MULFIX_INLINED.
  4197.  
  4198.  
  4199.         Add a new header named FT_ADVANCES_H declaring some new APIs to
  4200.         extract the advances of one or more glyphs without necessarily
  4201.         loading their outlines.  Also provide `fast loaders' for the
  4202.         TrueType, Type1, and CFF font drivers (more to come later).
  4203.  
  4204.         * src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files.
  4205.  
  4206.         * include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro.

  4208.  
  4209.         * include/freetype/internal/ftdriver.h (FT_Face_GetAdvancesFunc):
  4210.         `flags' and `advances' are now of type `FT_UInt' and `FT_Fixed',
  4211.         respectively.
  4212.  
  4213.         * src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC): Add

  4240.  
  4241.         * autogen.sh: Implement it.
  4242.         (get_major_version, get_minor_version, get_patch_version,
  4243.         compare_to_minimum_version, check_tool_version): New auxiliary
  4244.         functions.

  4249.  
  4250.         * src/sfnt/sfobjs.c (sfnt_open_font): Use TTAG_OTTO defined in
  4251.         ttags.h instead of FT_MAKE_TAG( 'O', 'T', 'T', 'O' ).
  4252.  
  4253. 2008-08-28  Werner Lemberg  <wl@gnu.org>
  4254.  
  4255.         * src/type1/t1load.c (parse_encoding): Protect against infinite
  4256.         loop.  This fixes Savannah bug #24150 (where a patch has been posted
  4257.         too).
  4258.  
  4259. 2008-08-23  Werner Lemberg  <wl@gnu.org>
  4260.  
  4261.         * src/type/t1afm.c (compare_kern_pairs), src/pxaux/afmparse.c
  4262.         (afm_compare_kern_pairs): Fix comparison.  This fixes Savannah bug
  4263.         #24119.
  4264.  
  4265. 2008-08-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  4266.  
  4267.         * src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,
  4268.         even if passed library or arguments are invalid.  This fixes a bug
  4269.         that an uninitialized stream is freed when an invalid library handle
  4270.         is passed.  Originally proposed by Mike Fabian, 2008/08/18 on
  4271.         freetype-devel.
  4272.         (FT_Open_Face): Ditto (stream).
  4273.         (load_face_in_embedded_rfork): Ditto (stream2).
  4274.  
  4275. 2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  4276.  
  4277.         * src/base/ftmac.c: Add a fallback to guess the availability of the
  4278.         `ResourceIndex' type.  It is used when built without configure
  4279.         (e.g., a build with Jam).
  4280.         * builds/mac/ftmac.c: Ditto.
  4281.         * builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0
  4282.         explicitly, even if `ResourceIndex' is unavailable.
  4283.  
  4284. 2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  4285.  
  4286.         * builds/unix/configure.raw: In checking of Mac OS X features,
  4287.         all-in-one header file `Carbon.h' is replaced by the minimum
  4288.         header file `CoreServices.h', similar to current src/base/ftmac.c.
  4289.  
  4290. 2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  4291.  
  4292.         * src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of
  4293.         sub-header when its code_count is 0.  Many Japanese Dynalab fonts
  4294.         include such an empty sub-header (code_count == 0, first_code == 0
  4295.         delta == 0, but offset != 0) as the second sub-header in SJIS cmap.
  4296.  
  4297. 2008-08-04  Werner Lemberg  <wl@gnu.org>
  4298.  
  4299.         * src/type1/t1tokens.h: Handle `ForceBold' keyword.  This fixes
  4300.         Savannah bug #23995.
  4301.  
  4302.         * src/cid/cidload.c (parse_expansion_factor): New callback function.
  4303.         (cid_field_records): Use it for `ExpansionFactor'.
  4304.         * src/cod/cidtoken.h: Handle `ForceBold' keyword.
  4305.         Don't handle `ExpansionFactor'.
  4306.  
  4307. 2008-08-04  Bram Tassyns  <bramt@enfocus.be>
  4308.  
  4309.         * src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which
  4310.         resulted in incorrect scaling.  This fixes Savannah bug #23973.
  4311.  
  4312. 2008-08-04  Werner Lemberg  <wl@gnu.org>
  4313.  
  4314.         Be more tolerant w.r.t. invalid entries in SFNT table directory.
  4315.  
  4316.         * src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and
  4317.         adjust table count.
  4318.         Add more trace messages.
  4319.         (tt_face_load_font_dir): Updated.
  4320.  
  4321. 2008-07-30  Werner Lemberg  <wl@gnu.org>
  4322.  
  4323.         * src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
  4324.         assume that the first argument on the stack is the bottom-most
  4325.         element.  Two reasons:
  4326.  
  4327.           o According to people from Adobe it is missing in the Type 2
  4328.             specification that pushing of additional, superfluous arguments
  4329.             on the stack is prohibited.
  4330.  
  4331.           o Acroread in general handles fonts differently, namely by popping
  4332.             the number of arguments needed for a particular operand (as a PS
  4333.             interpreter would do).  In case of buggy fonts this causes a
  4334.             different interpretation which of the elements on the stack are
  4335.             superfluous and which not.
  4336.  
  4337.         Since there are CFF subfonts (embedded in PDFs) which rely on
  4338.         Acroread's behaviour, FreeType now does the same.
  4339.  
  4340. 2008-07-27  Werner Lemberg  <wl@gnu.org>
  4341.  
  4342.         Add extra mappings for `Tcommaaccent' and `tcommaaccent'.  This
  4343.         fixes Savannah bug #23940.
  4344.  
  4345.         * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...
  4346.         (EXTRA_GLYPH_LIST_SIZE): This.
  4347.         Increase by 2.
  4348.         (ft_wgl_extra_unicodes): Rename to...
  4349.         (ft_extra_glyph_unicodes): This.
  4350.         Add two code values.
  4351.         (ft_wgl_extra_glyph_names): Rename to...
  4352.         (ft_extra_glyph_names): This.
  4353.         Add two glyphs.
  4354.         (ft_wgl_extra_glyph_name_offsets): Rename to...
  4355.         (ft_extra_glyph_name_offsets): This.
  4356.         Add two offsets.
  4357.  
  4358.         (ps_check_wgl_name, ps_check_wgl_unicode): Rename to...
  4359.         (ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This.
  4360.         Updated.
  4361.         (ps_unicodes_init): Updated.
  4362.  
  4363. 2008-07-26  Werner Lemberg  <wl@gnu.org>
  4364.  
  4365.         * src/cff/cffgload.c (cff_decoder_prepare,
  4366.         cff_decoder_parse_charstrings): Improve debug output.
  4367.  
  4368. 2008-07-22  Martin McBride  <mmcbride@emtex.com>
  4369.  
  4370.         * src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,
  4371.         tt_cmap4_char_map_binary): Handle fonts which treat the last segment
  4372.         specially.  According to the specification, such fonts would be
  4373.         invalid but acroread accepts them.
  4374.  
  4375. 2008-07-16  Jon Foster  <Jon.Foster@cabot.co.uk>
  4376.  
  4377.         * src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.
  4378.  
  4379.         * src/base/ftcalc.c (FT_MulFix): Fix portability issue.
  4380.  
  4381.         * src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]:
  4382.         Fix compiler warning.
  4383.  
  4384. 2008-07-16  Werner Lemberg  <wl@gnu.org>
  4385.  
  4386.         Handle CID-keyed fonts wrapped in an SFNT (with cmaps) correctly.
  4387.  
  4388.         * src/cff/cffload.c (cff_font_load): Pass `pure_cff'.
  4389.         Invert sids table only if `pure_cff' is set.
  4390.         * src/cff/cffload.h: Udpated.
  4391.  
  4392.         * src/cff/cffobjs.c (cff_face_init): Updated.
  4393.         Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set.
  4394.  
  4395.         * docs/CHANGES: Updated.
  4396.  
  4397. 2008-07-09  Werner Lemberg  <wl@gnu.org>
  4398.  
  4399.         * src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts
  4400.         where num_locations < num_glyphs.  Problem reported by Ding Li.
  4401.  
  4402. 2008-07-05  Werner Lemberg  <wl@gnu.org>
  4403.  
  4404.         Since FreeType uses `$(value ...)', we now need GNU make 3.80 or
  4405.         newer.  This fixes Savannah bug #23648.
  4406.  
  4407.         * configure: zsh doesn't like ${1+"$@"}.
  4408.         Update needed GNU make version.
  4409.         * builds/toplevel.mk: Check for `$(eval ...)'.
  4410.         * docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document
  4411.         it.
  4412.  
  4413. 2008-07-04  Werner Lemberg  <wl@gnu.org>
  4414.  
  4415.         * src/raster/ftraster.c (Draw_Sweep): If span is smaller than one
  4416.         pixel, only check for dropouts if neither start nor end point lies
  4417.         on a pixel center.  This fixes Savannah bug #23762.
  4418.  
  4419. 2008-06-29  Werner Lemberg  <wl@gnu.org>
  4420.  
  4421.         * Version 2.3.7 released.
  4422.         =========================
  4423.  
  4424.  
  4425.         Tag sources with `VER-2-3-7'.
  4426.  
  4427.         * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
  4428.         version number to 2.3.7.
  4429.  
  4430.         * README, Jamfile (RefDoc), builds/win32/visualc/index.html,
  4431.         builds/win32/visualc/freetype.dsp,

  4441.         * docs/release: Updated.
  4442.  
  4443. 2008-06-28  Werner Lemberg  <wl@gnu.org>
  4444.  
  4445.         * src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...
  4446.         * src/ftcalc.c: Here.  This fixes Savannah bug #23729.
  4447.  
  4448. 2008-06-27  Werner Lemberg  <wl@gnu.org>
  4449.  
  4450.         * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
  4451.         Horizontal_Gray_Sweep_Drop): Test for intersections which
  4452.         degenerate to a single point can be ignored; this has been confirmed
  4453.         by Greg Hitchcock from Microsoft.  (This was commented out code.)
  4454.  
  4455. 2008-06-26  Werner Lemberg  <wl@gnu.org>
  4456.  
  4457.         Improve navigation in API reference.
  4458.  
  4459.         * src/tools/docmaker/tohtml.py (html_header_3): Renamed to...
  4460.         (html_header_6): This.
  4461.         (html_header_3, html_header_3i, html_header_4, html_header_5,
  4462.         html_header_5t): New strings.
  4463.         (toc_footer_start, toc_footer_end): New strings.
  4464.         (HtmlFormatter::html_header): Updated.
  4465.         (HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header):
  4466.         New strings.
  4467.         (HtmlFormatter::index_enter): Use `html_index_header'.
  4468.         (HtmlFormatter::index_exit): Print `html_footer'.
  4469.         (HtmlFormatter::toc_enter): Use `html_toc_header'.

  4476.  
  4477. 2008-06-24  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  4478.  
  4479.         * builds/unix/configure.raw: Check type `ResourceIndex' explicitly
  4480.         and define HAVE_TYPE_RESOURCE_INDEX if it is defined.  Mac OS X 10.5
  4481.         bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
  4482.         ResourceIndex type definition.  The macro does not inform the type
  4483.         availability.
  4484.         * src/base/ftmac.c: More parentheses are inserted to clarify the
  4485.         conditionals to disable legacy APIs in `10.5 and later' cases.  If
  4486.         HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.
  4487.  
  4488. 2008-06-24  Werner Lemberg  <wl@gnu.org>
  4489.  
  4490.         * src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
  4491.         mode.
  4492.  
  4493.         * src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
  4494.         Draw_Sweep): No-dropout mode is value 2, not value 0.
  4495.         (Draw_Sweep): Really skip dropout handling for no-dropout mode.
  4496.  
  4497. 2008-06-24  Werner Lemberg  <wl@gnu.org>
  4498.  
  4499.         * src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
  4500.         if it consists of one point only.  Based on a patch from Savannah
  4501.         bug #23683 (from John Tytgat).
  4502.  
  4503. 2008-06-22  Werner Lemberg  <wl@gnu.org>
  4504.  
  4505.         * src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
  4506.         with IS_HINTED.
  4507.  
  4508.         * docs/CHANGES: Updated.
  4509.  
  4510. 2008-06-22  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  4511.  
  4512.         * builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
  4513.         but LDFLAGS does not, import it to LDFLAGS.  The option is used to
  4514.         specify non-default SDK on Mac OS X (e.g., universal binary SDK for
  4515.         Mac OS X 10.4 on PowerPC platform).  Although Apple TechNote 2137
  4516.         recommends to add the option only to CFLAGS, LDFLAGS should include
  4517.         it because libfreetype.la is built with -no-undefined.  This fixes a
  4518.         bug reported by Ryan Schmidt in MacPorts,
  4519.         http://trac.macports.org/ticket/15331.
  4520.  
  4521. 2008-06-21  Werner Lemberg  <wl@gnu.org>
  4522.  
  4523.         Enable access to the various dropout rules of the B&W rasterizer.
  4524.         Pass dropout rules from the TT bytecode interpreter to the
  4525.         rasterizer.
  4526.  
  4527.         * include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
  4528.         FT_OUTLINE_EXCLUDE_STUBS): New flags for FT_Outline.
  4529.  
  4530.         * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
  4531.         Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
  4532.         OpenType specification.
  4533.         Fix mode 4 computation.
  4534.         (Render_Glyph, Render_Gray_Glyph): Handle new outline flags.
  4535.  
  4536.         * src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
  4537.         mode to FT_OUTLINE_XXX flags.
  4538.  
  4539.         * src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.
  4540.  
  4541. 2008-06-19  Werner Lemberg  <wl@gnu.org>
  4542.  
  4543.         * src/cff/cffobjs.c (cff_face_init): Compute final
  4544.         `dict->units_per_em' value before assigning it to
  4545.         `cffface->units_per_EM'.  Otherwise, CFFs without subfonts are
  4546.         scaled incorrectly if the font matrix is non-standard.  This fixes
  4547.         Savannah bug #23630.
  4548.  
  4549.         * docs/CHANGES: Updated.
  4550.

  4567.         specification.
  4568.  
  4569. 2008-06-15  Werner Lemberg  <wl@gnu.org>
  4570.  
  4571.         * src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly
  4572.         from clobbering.  Patch from Savannah bug report #23556.
  4573.  
  4574.         * docs/CHANGES: Document it.
  4575.  
  4576. 2008-06-10  Werner Lemberg  <wl@gnu.org>

  4618.         Support debugging on WinCE.  From Savannah patch #6536; this fixes
  4619.         bug #23497.
  4620.  
  4621.         * builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro
  4622.         as a replacement for OutputDebugStringA (which WinCE doesn't have).
  4623.         Update all callers.
  4624.         (ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have
  4625.         environment variables.
  4626.

  4663.  
  4664.         * src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'

  4671.  
  4672. 2008-06-02  Werner Lemberg  <wl@gnu.org>
  4673.  
  4674.         Emit header info for defined FreeType objects in reference.

  4694.         * src/tools/docmaker/sources.py (SourceBlock::__init__): While
  4695.         looking for markup tags, return immediately as soon a single one is
  4696.         found.
  4697.  
  4698. 2008-05-28  Werner Lemberg  <wl@gnu.org>
  4699.  
  4700.         * src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses
  4701.         original, unscaled input values.  Confirmed by Greg Hitchcock from
  4702.         Microsoft.
  4703.  
  4704. 2008-05-27  Werner Lemberg  <wl@gnu.org>

  4711.         * src/raster/ftraster.c (fc_black_render): Return 0 when we are
  4712.         trying to render into a zero-width/height bitmap, not an error code.
  4713.  
  4714.         * src/truetype/ttgload.c (load_truetype_glyph): Move initialization
  4715.         of the graphics state for subglyphs to...
  4716.         (TT_Hint_Glyph): This function.
  4717.         Hinting instructions for a composite glyph apparently refer to the
  4718.         just hinted subglyphs, not the unhinted, unscaled outline.  This
  4719.         seems to fix Savannah bugs #20973 and (at least partially) #23310.
  4720.  
  4721. 2008-05-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

  4726.  
  4727. 2008-05-18  Werner Lemberg  <wl@gnu.org>
  4728.  
  4729.         * src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
  4730.         correction for pixel boundary.  Without this patch, the effect can
  4731.         be cumulative under certain circumstances, making glyphs taller and
  4732.         taller after each call.  This fixes Savannah bug #19976.
  4733.  
  4734. 2008-05-18  Werner Lemberg  <wl@gnu.org>
  4735.  
  4736.         * src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.

  4745.         ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make
  4746.         declarations non-global.
  4747.

  4770.  
  4771.         * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
  4772.         <op_closepath>: `closepath' without a path is a no-op, not an error
  4773.         (cf. the PS reference manual).
  4774.  
  4775.         Reported by Martin McBride.
  4776.  
  4777. 2008-05-15  Werner Lemberg  <wl@gnu.org>

  4781. 2008-05-15  Werner Lemberg  <wl@gnu.org>
  4782.  
  4783.         * src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
  4784.         which contains a single but empty entry.  This is technically
  4785.         invalid (since it must end with `return'), but...
  4786.  
  4787.         Reported by Martin McBride.
  4788.

  4801.         * src/cff/cffobjs.c (cff_make_private_dict): New function, using
  4802.         code from `cff_size_init'.
  4803.         (cff_size_init, cff_size_done, cff_size_select, cff_size_request):
  4804.         Use CFF_Internal and handle subfonts.
  4805.         (cff_face_init): Handle top-dict and subfont matrices correctly;
  4806.         apply some heuristic in case of unlikely matrix concatenation
  4807.         results.  This has been discussed with people from Adobe (thanks
  4808.         goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
  4809.         and not correct.
  4810.  
  4811.         * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.

  4813.         * src/cff/cffgload.c (cff_builder_init): Updated.

  4830.         * docs/CHANGES: Document it.
  4831.  
  4832. 2008-05-04  Werner Lemberg  <wl@gnu.org>

  4837.         * src/base/cff/cffparse.c (power_tens): New array.
  4838.         (cff_parse_real): Rewritten to introduce a fourth parameter which
  4839.         returns the `scaling' of the real number so that we have no
  4840.         precision loss.  This is not used yet.
  4841.         Update all callers.
  4842.         (cff_parse_fixed_thousand): Replace with...
  4843.         (cff_parse_fixed_scaled): This function.  Update all callers.
  4844.  
  4845. 2008-05-03  Werner Lemberg  <wl@gnu.org>
  4846.  
  4847.         * src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without
  4848.         transformation since it recursively calls FT_Load_Glyph.  This fixes
  4849.         Savannah bug #23143.
  4850.  
  4851. 2008-04-26  Werner Lemberg  <wl@gnu.org>

  4946.         * src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
  4947.         synthesis.  For any face of a specified FOND, always the name for
  4948.         the first face was used.  Except of a FOND that refers multiple
  4949.         Type1 font files, wrong synthesized font names are not used at all,
  4950.         so this is an invisible bug.  A few limit checks are added too.
  4951.  
  4952.         * builds/mac/ftmac.c: Ditto.
  4953.  
  4954. 2008-02-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

  4960.         is linked with other applications.  Suggested by Daniel Macks,
  4961.         Savannah bug #22366.

  4975.         * src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
  4976.         handle by its value instead of ResError(), fix provided by Deron
  4977.         Kazmaier.  According to the Resource Manager Reference,

  4981.         functions never return undefined values, so it is sufficient to
  4982.         check if the handle is not NULL.

  4988.         * src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other
  4989.         inclusion styles.  Now it always includes src/base/ftmac.c;
  4990.         builds/mac/ftmac.c is never included in any configuration.

  5049.  
  5050.         Improvement of POSIX resource-fork accessor to load unsorted
  5051.         references in a resource.  In HelveLTMM (resource-fork PostScript
  5052.         Type1 font bundled with Mac OS X since 10.3.x), the appearance order
  5053.         of PFB chunks is not sorted; sorting the chunks by reference IDs is
  5054.         required.
  5055.  
  5056.         * include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
  5057.         type to store a pair of reference ID and offset to the chunk.

  5067.         * src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
  5068.         division too early; otherwise the most significant digit(s) of the
  5069.         final result are lost as the value is truncated to an integer.  This
  5070.         fixes Savannah bug #21794 (where the patch has been posted too).
  5071.  
  5072. 2007-12-06  Fix  <4d876b82@gmail.com>
  5073.  
  5074.         Pass options from one configure script to another as-is (not
  5075.         expanded).  This is needed for options like
  5076.         --includedir='${prefix}/include'.
  5077.

  5145.         Fix MacOS legacy font support by Masatake Yamato on Mac OS X.  It is
  5146.         not working since 2.3.5.  In FT_Open_New(), if FT_New_Stream()
  5147.         cannot mmap() the specified file and cannot seek to head of the
  5148.         specified file, it returns NULL stream and FT_Open_New() returns the
  5149.         error immediately.  On MacOS, most legacy MacOS fonts fall into such
  5150.         a scenario because their data forks are zero-sized and cannot be
  5151.         sought.  To proceed to guessing of resource fork fonts, the
  5152.         functions for legacy MacOS font must properly handle the NULL stream
  5153.         returned by FT_New_Stream().
  5154.  
  5155.         * src/base/ftobjs.c (IsMacBinary): Return error
  5156.         FT_Err_Invalid_Stream_Operation immediately when NULL stream is
  5157.         passed.
  5158.         (FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
  5159.         to fallback.  Originally, legacy MacOS font is tested in the cases
  5160.         of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
  5161.         or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
  5162.         .dfont header is combined).  Now the case of
  5163.         FT_Err_Cannot_Open_Stream is included.
  5164.  
  5165.         * src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
  5166.         skip FT_Stream_Seek(), which seeks to the head of stream, and
  5167.         proceed to unit testing of raccess_guess_XXX().  FT_Stream_Seek()
  5168.         for a NULL stream causes a Bus error on Mac OS X.
  5169.         (raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
  5170.         immediately if passed stream is NULL.
  5171.         (raccess_guess_apple_single): Ditto.

  5174.  
  5175.         Fix for Carbon incompatibilities since Mac OS X 10.5,
  5176.         proposed by Sean McBride.
  5177.  
  5178.         * doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.
  5179.  
  5180.         * include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
  5181.         FT_GetFilePath_From_Mac_ATS_Name.  Since Mac OS X 10.5, calling
  5182.         Carbon functions from a forked process is classified as unsafe
  5183.         by Apple.  All Carbon-dependent functions should be deprecated.
  5184.  
  5185.         * src/base/ftmac.c: Use essential header files
  5186.         <CoreServices/CoreServices.h> and
  5187.         <ApplicationServices/ApplicationServices.h> instead of
  5188.         all-in-one header file <Carbon/Carbon.h>.
  5189.  
  5190.         Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
  5191.         genuine macro PATH_MAX.
  5192.  
  5193.         Add fallback macro for kATSOptionFlagsUnRestrictedScope which
  5194.         is not found in Mac OS X 10.0.
  5195.  
  5196.         Multi-character constants ('POST', 'sfnt' etc) are replaced by
  5197.         64bit constants calculated by FT_MAKE_TAG() macro.
  5198.  
  5199.         For the index in the segment of resource fork, new portable
  5200.         type ResourceIndex is introduced for better compatibility.
  5201.         This type is since Mac OS X 10.5, so it is defined as short
  5202.         when built on older platforms.
  5203.  
  5204.         (FT_ATSFontGetFileReference): If build target is only the systems
  5205.         10.5 and newer, it calls Apple genuine ATSFontGetFileReference().
  5206.  
  5207.         (FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
  5208.         and newer or 64bit platform, because legacy type FSSpec type is
  5209.         removed completely.
  5210.  
  5211.         (FT_New_Face_From_FSSpec): Ditto.
  5212.  
  5213. 2007-11-01  Werner Lemberg  <wl@gnu.org>
  5214.  
  5215.         * src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere.  This
  5216.         fixes Savannah bug #21485.
  5217.  
  5218. 2007-10-29  Daniel Svoboda  <dasvo@planeta@cz>
  5219.  
  5220.         * src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver
  5221.         can handle the font at all, then check `face_index'.  Otherwise, the
  5222.         driver might return the wrong error code.  This fixes Savannah bug
  5223.         #21468.
  5224.  
  5225. 2007-10-21  Werner Lemberg  <wl@gnu.org>
  5226.  
  5227.         * src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare
  5228.         support for bit 8 of the `fsSelection' field in the `OS/2' table.
  5229.         MS is already using this; hopefully, this becomes part of OpenType
  5230.         1.5.
  5231.         Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
  5232.         (WWS_SUBFAMILY).
  5233.  
  5234. 2007-10-20  Werner Lemberg  <wl@gnu.org>
  5235.  
  5236.         * src/tools/docmaker/tohtml.py (html_header_2): Fix typo.
  5237.         Add `td.left' element to CSS.
  5238.         (toc_section_enter): Use it.
  5239.  
  5240. 2007-10-18  David Turner  <david@freetype.org>
  5241.  
  5242.         * include/freetype/freetype.h, src/base/ftobjs.c: Rename API
  5243.         functions related to cmap type 14 support to the
  5244.         `FT_Object_ActionName' scheme:
  5245.  
  5246.           FT_Get_Char_Variant_index     -> FT_Face_GetCharVariantIndex
  5247.           FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault
  5248.           FT_Get_Variant_Selectors      -> FT_Face_GetVariantSelectors
  5249.           FT_Get_Variants_Of_Char       -> FT_Face_GetVariantsOfChar
  5250.           FT_Get_Chars_Of_Variant       -> FT_Face_GetCharsOfVariant
  5251.  
  5252.         Update documentation accordingly.
  5253.  
  5254.         * src/sfnt/ttcmap.c: Stronger cmap 14 validation.
  5255.         Make the code a little more consistent with FreeType coding
  5256.         conventions and modify the cmap14 functions that returned a newly
  5257.         allocated array to use a persistent vector from the TT_CMap14 object
  5258.         instead.
  5259.

  6142.         (_bdf_set_default_spacing): Increase `name' buffer size to 256 and

  6160.         * src/autofit/aflatin.c (af_latin_metrics_init_blues): Fix blues
  6161.         computations in order to ignore single-point contours.  These are
  6162.         never rasterized and correspond in certain fonts to mark-attach

  6164.         computation.
  6165.  
  6166.         * src/autofit/afloader.c (af_loader_load_g): In the case of
  6167.         monospaced fonts, always set `rsb_delta' and `lsb_delta' to 0.

  6199.  
  6200.         * builds/unix/configure.raw: Dequote `OS_INLINE' in comment of
  6201.         conftest.c, to avoid unexpected shell evaluation.  Possibly it is a
  6202.         bug or undocumented behaviour of autoconf.
  6203.  
  6204. 2007-03-18  David Turner   <david@freetype.org>

  6394. 2007-02-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  6395.

  6421.         =========================
  6422.  
  6423.  
  6424.         Tag sources with `VER-2-3-1-FINAL'.
  6425.

  6442.  
  6443.  
  6444.         * src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
  6445.         (af_loader_load_g): Disable the warper (i.e., the light hinting
  6446.         improvements) to make a 2.3.1 bugfix release before introducing a
  6447.         new feature.  This should give us more time to tune and improve the
  6448.         warper for the next release.
  6449.  
  6450.         * docs/CHANGES: Update accordingly.
  6451.  
  6452. 2007-01-25  David Turner  <david@freetype.org>
  6453.  
  6454.         For light auto-hinting, improve glyph advance widths and resurrect
  6455.         normal/full hinting to its normal quality.
  6456.  
  6457.         * src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
  6458.         and `xmax_delta'.
  6459.         * src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
  6460.         and `xmax_delta'.
  6461.

  6463.         preprocessor conditional with if-clause, handling both light and
  6464.         normal mode.
  6465.  
  6466.         * src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.
  6467.         (af_warper_compute): Handle `xmin_delta' and `xmax_delta'.
  6468.  
  6469. 2007-01-25  Werner Lemberg  <wl@gnu.org>
  6470.  
  6471.         * docs/release: Updated -- Savannah uses a new uploading scheme.
  6472.  
  6473. 2007-01-25  David Turner  <david@freetype.org>
  6474.  
  6475.         * src/cff/cffload.c (cff_index_get_pointers): Improve previous fix.
  6476.

  6482.  
  6483. 2007-01-25  Werner Lemberg  <wl@gnu.org>
  6484.  
  6485.         * src/cff/cffload.c (cff_index_get_pointers): Handle last entry
  6486.         correctly in a sanity check.  Since this function is only used to
  6487.         load local and global functions, any charstring that called the last
  6488.         local/global function would fail otherwise.  This fixes Savannah bug
  6489.         #18867.
  6490.  
  6491.         * docs/CHANGES: Document it.
  6492.

  6500.         Fix and enable the warper to improve `light' hinting mode.  This is
  6501.         not necessarily a final version, but it seems to work well.
  6502.  
  6503.         * src/autofit/aflatin.c (af_latin_hints_init) [AF_USE_WARPER]:
  6504.         Disable code.

  6506.         * src/autofit/aftypes.h: Activate AF_USE_WARPER.

  6508.         * src/autofit/afwarp.c (AF_WarpScore): Tune table.
  6509.         (af_warper_compute_line_best): Fix array size of `scores'.
  6510.         (af_warper_compute): Better handling of border cases.
  6511.         * src/autofit/afwarp.h (AF_WarperRec): Remove unused members `X1'
  6512.         and `X2'.
  6513.  
  6514. 2007-01-21  Werner Lemberg  <wl@gnu.org>
  6515.  
  6516.         * ChangeLog: Split off older entries into...

  6526.         points.
  6527.  
  6528. 2007-01-21  Werner Lemberg  <wl@gnu.org>
  6529.

  6601.         with C++ compiler.
  6602.  
  6603.         * src/autofit/afhints.c (af_glyph_hints_dump_segments,

  6644.         Yamato.
  6645.  
  6646.         * autogen.sh: Small fix to get it working on Mac OS X properly:
  6647.         The issue is that GNU libtool is called `glibtool' on this platform,
  6648.         and we must call `glibtoolize', since `libtoolize' doesn't exist.
  6649.

  6682.         * src/sfnt/ttload.c (tt_face_load_gasp): Add version check for the

  6710.  
  6711.         * src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts
  6712.         correctly.  This fixes Savannah bug #17876.
  6713.  
  6714.  
  6715.         Do not allocate interpreter-specific tables in memory if we are not
  6716.         going to load glyphs with the bytecode interpreter anyway.
  6717.  
  6718.         * src/truetype/ttgload.c (tt_loader_init): Load execution context

  6728.         (tt_size_reset): Move some code to `tt_size_ready_bytecode'.
  6729.  
  6730.  
  6731.         Don't extract the metrics table from the SFNT font file.  Instead,
  6732.         reparse it on each glyph load.  The runtime difference is not
  6733.         noticeable, and it can save a lot of heap memory when memory-mapped
  6734.         files are not used.
  6735.  
  6736.         * include/freetype/internal/tttypes.h (TT_FaceRec): Add members

  6743.  
  6744.  
  6745.         Do not load the CFF index offsets into memory, since this wastes a
  6746.         *lot* of heap memory with large Asian CFF fonts.  There is no
  6747.         significant performance loss.
  6748.  
  6749.         * src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.
  6750.         * src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and

  6759.         (cff_done_index): Renamed to...
  6760.         (cff_index_done): This.  Update all callers.
  6761.         (cff_index_get_pointers, cff_index_access_element): Updated to use
  6762.         stream offsets.

  6791.         (ft_black_init): Don't initialize `count_table'.

  6809.         FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since
  6810.         the optimization is no longer experimental.
  6811.  
  6812.         * src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
  6813.         Remove a typo that results in no hinting and a memory leak with some
  6814.         large Asian CFF fonts.
  6815.  
  6816.         * src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
  6817.         which happens when FT_Done_Library is called with still opened
  6818.         CFF_Faces in it.  We need to close all faces before destroying the
  6819.         modules, or else some bad things (memory leaks) may happen.

  6983. 2006-11-18  Werner Lemberg  <wl@gnu.org>
  6984.  
  6985.         Because FT_Load_Glyph expects CID values for CID-keyed fonts, the

  6987.         This patch fixes Savannah bug #18301.
  6988.  
  6989.         * src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.

  6998.  
  6999.         * src/truetype/ttinterp.c (FIX_BYTECODE): Undefine.  The interpreter
  7000.         `enhancements' are still too buggy for general use.
  7001.  
  7002.         * src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and
  7003.         FT_FORCE_LEGACY_LCD_FILTER at compile time.  Define these macros
  7004.         when building the library to change the default LCD filter to be

  7015.         algorithm which produces strong color fringes for everything
  7016.         except very-well hinted text).
  7017.  
  7018.         * include/freetype/ftlcdfil.h (FT_Library_SetLcdFilter): Change

  7037.  
  7038.         * src/autofit/aflatin.c: Various tiny improvements that drastically
  7039.         improve the handling of serif fonts and of LCD/LCD_V hinting modes.
  7040.         (af_latin_hints_compute_edges): Fix typo.
  7041.         (af_latin_compute_stem_width): Take better care of diagonal stems.
  7042.  
  7043. 2006-11-09  David Turner  <david@freetype.org>
  7044.  
  7045.         * src/pshinter/pshalgo.c (psh_glyph_compute_inflections): Fix
  7046.         typo which created a variable-used-before-initialized bug.
  7047.  
  7048. 2006-11-07  Zhe Su  <james.su@gmail.com>

  7054.  
  7055.         * src/base/ftcalc.c: Don't use `long long' but `FT_Int64'.
  7056.  
  7057. 2006-11-02  David Turner  <david@freetype.org>
  7058.  
  7059.         Add a few tweaks to better handle serif fonts.
  7060.         Add more debugging messages.
  7061.  
  7062.         * src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore
  7063.         segments that are less than 1.5 pixels high.  This gets rid of
  7064.         *many* corner cases with serifs.
  7065.         (af_latin_align_linked_edge): Add logging message.
  7066.         (af_latin_hint_edges): Use AF_HINTS_DO_BLUES.

  7247.         In a default build, the function `FT_Library_SetLcdFilter' returns
  7248.         `FT_Err_Unimplemented_Feature'; you need to #define
  7249.         FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the

  7288.         _af_debug_disable_vert_hints) [AF_DEBUG]: New global variables.
  7289.  
  7290.         * src/autofit/aftypes.h [AF_DEBUG]: Declare above variables.

  7293.         (FT_CONFIG_OPTION_SUBPIXEL_RENDERING): New macro to control whether
  7294.         we want to compile LCD-optimized rendering code (à la ClearType) or
  7295.         not.  The macro *must* be disabled in default builds of the library
  7296.         for patent reasons.
  7297.  
  7298.         * src/smooth/ftsmooth.c (ft_smooth_render_generic): Disable
  7299.         LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
  7300.         isn't defined at compile time.  This only changes the content of the
  7301.         rendered glyph to match the one of normal gray-level rendering,
  7302.         hence clients should not need to be modified.
  7303.  
  7304.         * docs/CHANGES: Updated.
  7305.  
  7306. 2006-09-18  Garrick Meeker  <garrick@digitalanarchy.com>
  7307.

  7317.         If the font uses another name entry with language_id == English, it
  7318.         will be selected correctly, though.
  7319.  
  7320.         * src/truetype/ttobjs.c (tt_face_init): Add unpatented hinting
  7321.         selection for `mingli.ttf'.

  7326.         values which have the upper two bytes set to 0xFF instead of 0x00
  7327.         (as it happens in at least two CJKV fonts, `HAN NOM A.ttf' and
  7328.         `HAN NOM B.ttf').
  7329.  
  7330.         * src/smooth/ftgrays.c [GRAYS_USE_GAMMA]: Really remove all code.
  7331.

  7760.         Public API of TrueTypeGX, OpenType, and classic kern table validator
  7761.         should return `FT_Err_Unimplemented_Feature' if validation service

  7787. 2006-06-06  David Turner  <david@freetype.org>
  7788.  
  7789.         Fix memory leak described in Savannah bug #16759.
  7790.  
  7791.         We change `ps_unicodes_init' so that it also takes a
  7792.         `free_glyph_name' callback to release the glyph names returned by
  7793.         `get_glyph_name'
  7794.  
  7795.         * include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc):

  7813.  
  7814.         * src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept
  7815.         `item_size == 0' as well -- though this sounds weird, it can

  7817.  
  7818.         * src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
  7819.         of `face->num_glyphs' which missed the last glyph, due to
  7820.         the offset-by-1 computation, since the PFR format doesn't
  7821.         guarantee that glyph index 0 corresponds to the `missing
  7822.         glyph.  This fixes Savannah bug #16668.

  7830.  
  7831.         * builds/win32/visualc/freetype.dsp: Release libraries no longer
  7832.         have debug information, and debug libraries use `C7 compatible'

  7834.  
  7835. 2006-05-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  7836.

  7856.  
  7857. 2006-05-18  Werner Lemberg  <wl@gnu.org>
  7858.  
  7859.         * src/truetype/ttgload.c (TT_Load_Composite_Glyph)
  7860.         [FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.
  7861.  
  7862. 2006-05-17  David Turner  <david@freetype.org>
  7863.  
  7864.         This is a major patch used to drastically improve the performance of
  7865.         loading glyphs.  This both speeds up loading the glyph vectors
  7866.         themselves and the auto-fitter module.
  7867.  
  7868.         We now use inline assembler code with GCC to implement `FT_MulFix',
  7869.         which is probably the most important function related to the
  7870.         engine's performance.
  7871.  
  7872.         The resulting speed-up is about 25%.
  7873.  
  7874.  
  7875.         * include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
  7876.         `cursor' and `limit'.
  7877.  
  7878.         * src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):
  7879.         New functions.
  7880.         (AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
  7881.         [TEST]: Remove.
  7882.  
  7883.         * src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
  7884.         code.
  7885.  
  7886.         * src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
  7887.         `FT_ZERO'
  7888.         (af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
  7889.         (af_glyph_hints_reload: Rewrite recognition of weak points.
  7890.  
  7891.         * src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
  7892.         constant values out of the loops.
  7893.  
  7894.         * src/autofit/aftypes.h: Updated.
  7895.  
  7896.         * src/base/ftcalc.c (FT_MulFix): Use inline assembler code.
  7897.  
  7898.         * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
  7899.         product to get orientation.
  7900.  
  7901.         * src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
  7902.         (FT_Stream_OpenGzip): Use it to handle small files directly in
  7903.         memory.
  7904.  
  7905.         * src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
  7906.         Improve performance.
  7907.  
  7908.         * src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
  7909.         `limit'.
  7910.  
  7911.         (TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
  7912.         TT_Load_Composite_Glyph): Updated.  Add threshold to protect against
  7913.         exceedingly large values of number of contours.  Speed up by
  7914.         reducing the number of loops.
  7915.  
  7916.         * src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.
  7917.  
  7918.  
  7919.         * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
  7920.         used to detect rogue clients from 4 to 16.  This is to prevent some
  7921.         segmentation faults with fonts like `KozMinProVI-Regular.otf' which
  7922.         comes from the Japanese Adobe Reader Asian Font pack.
  7923.  
  7924. 2007-05-17  Werner Lemberg  <wl@gnu.org>
  7925.  
  7926.         * src/cff/cffload.c (cff_font_done): Deallocate subfont array.  This
  7927.         fixes the first part of Savannah bug #16590.
  7928.  
  7929. 2006-05-16  Werner Lemberg  <wl@gnu.org>
  7930.
