5edc2f33 | 2010-10-01 08:15:55 | Fix Savannah bug #31040. * src/truetype/ttinterp.c (free_buffer_in_size): Remove. (TT_RunIns): Updated. | |
|
d2b8b8db | 2010-09-20 19:06:23 | [sfnt] Make error message filling NULL names less verbose. * src/sfnt/ttpost.c (load_format_20): Showing 1 summary message when we fill `post' names by NULL, instead of per-entry message. | |
 |
e0a9a933 | 2010-09-20 09:29:23 | [smooth] Fix and improve spline flattening. This fixes the flattening of cubic, S-shaped curves and speeds up the handling of both the conic and cubic arcs. See the discussions on the freetype-devel mailing list in late August and September 2010 for details. * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): New macro. (TWorker): Remove `conic_level' and `cubic_level' elements. (gray_render_conic): Simplify algorithm. (gray_render_cubic): New algorithm; details are given in the code comments. (gray_convert_glyph): Remove heuristics. | |
 |
d38ba0c9 | 2010-09-19 20:51:19 | Minor fixes. * src/cff/cffload.c (cff_charset_compute_cids): `charset->sids[i]' is `FT_UShort'. (cff_index_access_element): Don't use additions in comparison. * src/sfnt/ttpost.c (load_format_20): Make `post_limit' of type `FT_Long'. Don't use additions in comparison. Improve tracing messages. (load_format_25, load_post_names): Make `post_limit' of type `FT_Long'. | |
|
73aa20ca | 2010-09-20 01:30:38 | [cff] Truncate the element length at the end of the stream. See Savannah bug #30975. * src/cff/cffload.c (cff_index_access_element): `off2', the offset to the next element is truncated at the end of the stream to prevent invalid I/O. As `off1', the offset to the requested element has been checked by FT_STREAM_SEEK(), `off2' should be checked similarly. | |
|
d2d843a0 | 2010-09-20 01:28:17 | [cff] Ignore CID > 0xFFFFU. See Savannah bug #30975. * src/cff/cffload.c (cff_charset_compute_cids): Ignore CID if greater than 0xFFFFU. CFF font spec does not mention about maximum CID in the font, but PostScript and PDF spec define that maximum CID is 0xFFFFU. | |
|
a0f43f20 | 2010-09-20 01:26:56 | [cff] Make trace message in cff_charset_load() verbose. See Savannah bug #30975. * src/cff/cffload.c (cff_charset_load): Report the original `nleft' and truncated `nleft'. | |
|
b3e1954d | 2010-09-20 01:22:34 | [cff] Correct `max_cid' from CID array length to max CID. See Savannah bug #30975. * src/cff/cffload.c (cff_charset_compute_cids): Don't increment max_cid after detecting max CID. The array CFF_Charset->cids is allocated by max_cid + 1. (cff_charset_cid_to_gindex): Permit CID is less than or equal to CFF_Charset->max_cid. * src/cff/cffobjs.c (cff_face_init): FT_Face->num_glyphs is calculated as CFF_Charset->max_cid + 1. | |
|
643d49df | 2010-09-20 01:07:57 | [truetype] Sanitize the broken offsets in `loca'. * src/truetype/ttpload.c (tt_face_get_location): If `pos1', the offset to the requested entry in `glyf' exceeds the end of the table, return offset=0, length=0. If `pos2', the offset to the next entry in `glyf' exceeds the end of the table, truncate the entry length at the end of `glyf' table. See Savannah bug #31040. | |
|
900e7e0c | 2010-09-20 01:03:36 | [sfnt] Prevent overrunning in `post' table parser. * src/sfnt/ttpost.c (load_post_names): Get the length of `post' table and pass the limit of `post' table to load_format_20() and load_format_25(). (load_format_20): Stop the parsing when we reached at the limit of `post' table. If more glyph names are required, they are filled by NULL names. See Savannah bug #31040. | |
|
db053ec9 | 2010-09-17 23:20:00 | [truetype] Don't duplicate size->twilight structure to be freed. * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate FT_GlyphZoneRec size->twilight to be freed. If duplicated, FT_FREE() erases the duplicated pointers only and leave original pointers. They can cause the double-free crash when the burst errors occur in TrueType interpreter and free_buffer_in_size() is invoked repeatedly. See Savannah bug #31040 for detail. | |
|
afd89d30 | 2010-09-15 13:02:35 | Make bytecode debugging with FontForge work again. * src/truetype/ttinterp.c (TT_RunIns): Don't call `free_buffer_in_size' in case of error if a debugger is active. | |
|
6abb9232 | 2010-09-14 09:02:10 | Improve tracing messages. * src/truetype/ttinterp.c (TT_RunIns): Improve wording of tracing message. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Add tracing message. * src/truetype/ttgload.c (tt_loader_init): Add tracing message. * src/cache/ftcsbits.c (ftc_snode_load): Emit tracing message if glyph doesn't fit into a small bitmap container. | |
|
5220ef58 | 2010-09-13 07:32:22 | Fix minor issues reported by <muktha.narayan@wipro.com>. * src/autofit/aflatin.c (af_latin_compute_stem_width): Remove redundant conditional check. * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto. * src/cff/cffload.c (cff_encoding_load): Remove conditional check which always evaluates to `true'. * src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points): Ditto. * src/truetype/ttinterp.c (Ins_IUP): Ditto. * src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if value is already dereferenced. * src/winfonts/winfnt.c (FNT_Load_Glyph): Fix check of `face'. | |
|
0eb657b0 | 2010-08-31 13:29:05 | [truetype] Decrease the trace level catching the interpreter error. * src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level showing the error when the interpreter returns with an error, from FT_TRACE7() to FT_TRACE1(). | |
 |
29e044a4 | 2010-08-31 01:23:30 | [truetype] Prevent bytecode reuse after the interpretation error. * src/truetype/ttinterp.c (free_buffer_in_size): New function to free the buffer allocated during the interpretation of this glyph. (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if an error occurs in the bytecode interpretation. The interpretation of invalid bytecode may break the function definitions and referring them in later interpretation is danger. By unsetting these flags, `fpgm' and `prep' tables are executed again in next interpretation. Fix Savannah bug #30798, reported by Robert Swiecki. | |
|
12cf0316 | 2010-08-29 11:02:24 | [ftraster] Pacify compiler. * src/raster/ftraster.c (ft_black_new) [_STANDALONE_]: `memory' is not used. | |
|
0e95b3d1 | 2010-08-29 10:46:26 | [cff] Allow SIDs >= 65000. * src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20: The threshold for SIDs is not applicable here. I misinterpreted the `SID values 65000 and above are available for implementation use' sentence in the CFF specification. Problem reported by Ivan Ninčić <inincic@pdftron.com>. | |
|
0eb9b1f5 | 2010-08-28 21:41:16 | Force hinting when the font lacks its familyname. In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt stream may lack `name' table because they are not required. Hinting for nameless fonts is safer for PDFs including embedded Chinese fonts. Written by David Bevan, see: http://lists.gnu.org/archive/html/freetype-devel/2010-08/msg00021.html http://lists.freedesktop.org/archives/poppler/2010-August/006310.html * src/truetype/ttobjs.c (tt_check_trickyness): If a NULL pointer by nameless font is given, TRUE is returned to enable hinting. | |
|

 |
ebaeb642 | 2010-08-17 07:40:55 | Fix Savannah bug #30788. * src/cache/ftccache.c (FTC_Cache_Clear): Check `cache->buckets' for NULL too. | |
|
a205b3ca | 2010-08-10 02:59:12 | Try to fix Savannah bug #30717 (and probably #30719 too). * src/smooth/ftsmooth.c (ft_smooth_render_generic): Add another overflow test for `width' and `height'. | |
|

|
44524158 | 2010-08-07 01:46:56 | Fix Savannah bug #30648. * src/base/ftobjs.c (FT_Done_Library): Specify the order of font drivers in face closing process. Type42 faces should be closed before TrueType faces, because a Type42 face refers another internal TrueType face which is created from sfnt[] array on the memory. | |
 |
c9de9cbd | 2010-08-06 08:20:28 | [raster] Fix valgrind warning. * src/raster/ftraster.c (Decompose_Curve) <default>: Access point[0] only if we don't hit `limit'. | |
|
81f3472c | 2010-08-06 14:11:54 | Fix Savannah bug #30658. * src/base/ftobjs.c (Mac_Read_POST_Resource): Check the total length of collected POST segments does not overrun the allocated buffer. | |
|

|
d9b3e394 | 2010-08-05 17:10:32 | [cff] Don't use any values in decoder after parsing error. * src/cff/cffgload.c (cff_slot_load): Skip the evaluations of the values in decoder, if cff_decoder_parse_charstrings() returns any error. | |
|
45a3c76b | 2010-08-04 15:54:55 | Fix Savannah bug #30644. * src/base/ftstream.c (FT_Stream_EnterFrame): Fix comparison. | |

|
2de6b8a3 | 2010-07-17 13:39:50 | [cff] Final try to fix `hintmask' and `cntrmask' limit check. Problem reported by Tobias Wolf <towolf@gmail.com>. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_hintmask>: Sigh. I'm apparently too silly to fix this correctly in less than three tries. | |

|
0ae32718 | 2010-07-04 20:14:18 | Restrict the number of the charmaps in a rogue-compatible mode. Fix for Savannah bug #30059. * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Replace `16' the minimum character code passed by a legacy rogue client by... * include/freetype/config/ftoption.h (FT_MAX_CHARMAP_CACHEABLE): This.

|
b2ea64bc | 2010-07-02 18:16:02 | Additional fix for Savannah bug #30306. * src/base/ftobjs.c (Mac_Read_POST_Resource): If the type of the POST fragment is 0, the segment is completely ignored. The declared length of the segment is not cared at all. According to Adobe Technical Note 5040, type 0 segment is comment only and should not be loaded for the interpreter. Reported by Robert Swiecki. | |

88169b10 | 2010-05-11 00:03:33 | Fix Savannah bug #29846. Previously we discovered fonts which used `setcurrentpoint' to set the initial point of a contour to 0,0. This caused FreeType to raise an error, because the `setcurrentpoint' operator is only supposed to be used with the results from an OtherSubr subroutine. This was fixed by simply ignoring the error and carrying on. Now we have found a font which uses setcurrentpoint to actually establish a non-zero point for a contour during the course of a glyph program. FWIW, these files may be produced by an application called `Intaglio' on the Mac, when converting TrueType fonts to Type 1. The fix allows the new invalid behaviour, the old invalid behaviour and real proper usage of the operator to work the same way as Adobe interpreters apparently do. (t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top two elements of the stack to establish unconditionally the current x and y coordinates. Make the `flex' subroutine handling (OtherSubr 0) put the current x,y coordinates onto the stack, instead of two dummy uninitialised values. | |
