| 35 | [ftfuzzer] Replace `rand' with an xorshift algorithm. |
| 36 | |
| 37 | * src/tools/ftfuzzer/ftfuzzer.cc: Don't include `stdlib.h'. |

| 39 | |
| 40 | 2016-12-30 Werner Lemberg <wl@gnu.org> |
| 41 | |
| 42 | [ftfuzzer] Restrict number of tested bitmap strikes. |
| 43 | |
| 44 | Malformed fonts often have large values for the number of bitmap |
| 45 | strikes, and FreeType doesn't check the validity of all bitmap |
| 46 | strikes in advance. |

| 79 | [truetype] Tracing fixes. |
| 80 | |

| 103 | [psnames] Only declare, not define, data in `pstables.h' (#49949). |
| 104 | |
| 105 | Pdfium includes `pstables.h' a second time; moving the definition |

| 320 | |
| 321 | [truetype] Fix linear metrics of GX variation fonts (#49829). |
| 322 | |
| 323 | When asking for an unhinted non-default variations, |
| 324 | `linearVertAdvance' is currently the value from the `hmtx' table |
| 325 | instead of the actual value after applying the variation. `HVAR' |
| 326 | support fixes this, but fonts will exist without that table and will |
| 327 | need sane fallback. |

| 505 | [cff] Implement CFF2 support (2/2). |
| 506 | |
| 507 | The font variation code. All parts dependent on the GX code in the |
| 508 | `truetype' module are guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT. |
| 509 | In other words, you can still compile the `cff' module without |
| 510 | defining TT_CONFIG_OPTION_GX_VAR_SUPPORT (which brings you CFF2 |
| 511 | support without font variation). |
| 512 | |
| 513 | * src/cff/cf2font.c (cf2_font_setup): Add support for font |
| 514 | variation. |

| 524 | (cf2_doBlend): New function. |
| 525 | (cf2_interpT2CharString): Handle `vsindex' and `blend' opcodes. |
| 526 | |
| 527 | * src/cff/cffload.c (FT_fdot14ToFixed): New macro. |
| 528 | (cff_vstore_done, cff_vstore_load): New functions. |
| 529 | (cff_blend_clear, cff_blend_doBlend, cff_blend_build_vector, |
| 530 | cff_blend_check_vector): New functions. |
| 531 | (cff_load_private_dict): Add arguments for blend vector. |

| 547 | |
| 548 | * src/cff/cfftoken.h: Handle `vstore', `vsindex', and `blend' |
| 549 | dictionary values. |
| 550 | |
| 551 | * src/cff/cfftypes.h (CFF_VarData, CFF_AxisCoords, CFF_VarRegion, |
| 552 | CFF_VStore, CFF_Blend): New structures. |
| 553 | (CFF_FontRecDict): Add `vstore_offset' field. |
| 554 | (CFF_Private): Add `vsindex' field. |
| 555 | (CFF_SubFont): Add fields for blend data. |
| 556 | (CFF_Font): Add `vstore' field. |

| 910 | [gzip] Improve building with external zlib (#49673). |
| 911 | |
| 912 | Building FreeType with external zlib 1.2.8 makes msvc 14 stop with |
| 913 | the following error. |
| 914 | |
| 915 | ftgzip.c |
| 916 | zlib-1.2.8\zlib.h(86): error C2061: |
| 917 | syntax error: identifier 'z_const' |
| 918 | zlib-1.2.8\zlib.h(94): error C2054: |
| 919 | expected '(' to follow 'z_const' |
| 920 | zlib-1.2.8\zlib.h(94): error C2085: |
| 921 | 'msg': not in formal parameter list |
| 922 | ... |
| 923 | zlib-1.2.8\zlib.h(877): fatal error C1003: |
| 924 | error count exceeds 100; stopping compilation |
| 925 | |
| 926 | The error happens because FreeType keeps an own copy of zlib-1.1.4 |
| 927 | under `src/gzip'. When building `src/gzip/ftgzip.c' with |
| 928 | FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses |
| 929 | |
| 930 | #include <zlib.h> |
| 931 | |
| 932 | which correctly finds an external `zlib.h', but `zlib.h' itself has |
| 933 | a line |
| 934 | |
| 935 | #include "zconf.h" |
| 936 | |
| 937 | which makes Visual Studio 2015 find `src/gzip/zconf.h' while |
| 938 | compiling the files in `src/gzip'. |
| 939 | |
| 940 | * src/gzip/zconf.h: Rename to... |
| 941 | * src/gzip/ftzconf.h: ... this. |
| 942 | * src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated. |

| 1019 | * src/sfnt/ttsbit.c (tt_face_load_sbit): Store `sbix' size and |
| 1020 | offset also in `ebdt_size' and `ebdt_start', respectively. This |
| 1021 | makes the test for an embedded bitmap data table succeed for this |
| 1022 | format. |
| 1023 | |
| 1024 | (tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_SBIX>: Use |

| 1030 | |
| 1031 | Introduce a way of quickly retrieving (embedded) bitmap metrics. |
| 1032 | |
| 1033 | `FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph |
| 1034 | until the user calls `FT_Render_Glyph'. However, it always |
| 1035 | allocates memory for bitmaps and copies or decodes the contents of a |
| 1036 | bitmap glyph, which can be quite slow for PNG data. |
| 1037 | |
| 1038 | * include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New |
| 1039 | macro. |
| 1040 | |

| 1048 | tt_face_load_sbit_image): Updated. |

| 1212 | [pcf] Enrich family name with foundry name and glyph width info. |
| 1213 | |
| 1214 | This is a very old patch from openSuSE (from 2006, submitted to |

| 1216 | |
| 1217 | https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch |
| 1218 | |
| 1219 | Prepend the foundry name plus a space to the family name. There are |
| 1220 | many fonts just called `Fixed' which look completely different, and |
| 1221 | which have nothing to do with each other. When selecting `Fixed' in |
| 1222 | KDE or Gnome one gets results that appear rather random, the style |
| 1223 | changes often if one changes the size and one cannot select some |
| 1224 | fonts at all. |
| 1225 | |
| 1226 | We also check whether we have `wide' characters; all put together, |
| 1227 | we get family names like `Sony Fixed' or `Misc Fixed Wide'. |

| 1295 | |
| 1296 | [truetype] Trace number of executed opcodes. |
| 1297 | |
| 1298 | * src/truetype/ttinterp.c (TT_RunIns): Implement it. |
| 1299 | |
| 1300 | 2016-09-27 Werner Lemberg <wl@gnu.org> |
| 1301 | |
| 1302 | [truetype] Speed up `TT_Load_Glyph'. |
| 1303 | |
| 1304 | This avoids additional calls to `tt_face_lookup_table' for the |
| 1305 | `glyf' table, which can be expensive. |
| 1306 | |
| 1307 | * include/freetype/internal/tttypes.h (TT_LoaderRec): Move |
| 1308 | `glyf_offset' field to ... |
| 1309 | (TT_FaceRec): ... this structure. |
| 1310 | * src/truetype/ttgload.c (load_truetype_glyph): Updated. |
| 1311 | (tt_loader_init): Move initialization of `glyf_offset' to ... |
| 1312 | * src/truetype/ttpload.c (tt_face_load_loca): ... this function. |
| 1313 | |
| 1314 | 2016-09-27 Werner Lemberg <wl@gnu.org> |
| 1315 | |
| 1316 | [truetype] Introduce dynamic limits for some bytecode opcodes. |
| 1317 | |
| 1318 | This speeds up FreeType's handling of malformed fonts. |
| 1319 | |
| 1320 | * src/truetype/ttinterp.c (TT_RunIns): Set up limits for the number |
| 1321 | of twilight points, the total number of negative jumps, and the |
| 1322 | total number of loops in LOOPCALL opcodes. The values are based on |
| 1323 | the number of points and entries in the CVT table. |
| 1324 | (Ins_JMPR): Test negative jump counter. |
| 1325 | (Ins_LOOPCALL): Test loopcall counter. |
| 1326 | |
| 1327 | * src/truetype/ttinterp.h (TT_ExecContext): Updated. |
| 1328 | |
| 1329 | * docs/CHANGES: Updated. |
| 1330 | |
| 1331 | 2016-09-25 Werner Lemberg <wl@gnu.org> |
| 1332 | |
| 1333 | [truetype] Sanitize only last entry of `loca' table. |
| 1334 | |
| 1335 | Without this patch, a loca sequence like `0 100000 0 100000 ...', |
| 1336 | where value 100000 is larger than the `glyf' table size, makes |
| 1337 | FreeType handle the whole `glyf' table as a single glyph again and |
| 1338 | again, which is certainly invalid (and can be very slow, too). |
| 1339 | |
| 1340 | * src/truetype/ttpload.c (tt_face_get_location): Implement. |
| 1341 | Improve tracing messages. |
| 1342 | |
| 1343 | 2016-09-25 Werner Lemberg <wl@gnu.org> |
| 1344 | |
| 1345 | * src/tools/ftfuzzer/ftfuzzer.cc (LLVMFuzzerTestOneInput): Fix typo. |
| 1346 | |
| 1347 | 2016-09-24 Werner Lemberg <wl@gnu.org> |
| 1348 | |
| 1349 | [autofit] Tracing fixes. |
| 1350 | |
| 1351 | * src/autofit/afmodule.c (af_autofitter_load_glyph): Call dumping |
| 1352 | functions only if we actually do tracing. |
| 1353 | |
| 1354 | 2016-09-22 Alexei Podtelezhnikov <apodtele@gmail.com> |
| 1355 | |
| 1356 | [smooth] Reduce divisions in the line renderer. |
| 1357 | |
| 1358 | We don't need some divisions if a line segments stays within a single |
| 1359 | row or a single column of pixels. |
| 1360 | |
| 1361 | * src/smooth/ftgrays.c (gray_render_line) [FT_LONG64]: Make divisions |
| 1362 | conditional. |
| 1363 | |
| 1364 | 2016-09-15 Alexei Podtelezhnikov <apodtele@gmail.com> |
| 1365 | |
| 1366 | * src/smooth/ftgrays.c (gray_sweep): Remove check for empty table. |
| 1367 | |
| 1368 | 2016-09-14 Alexei Podtelezhnikov <apodtele@gmail.com> |
| 1369 | |
| 1370 | [smooth] Another tiny speed-up. |
| 1371 | |
| 1372 | * src/smooth/ftgrays.c (gray_find_cell): Merge into... |
| 1373 | (gray_record_cell): ... this function. |
| 1374 | |
| 1375 | 2016-09-11 Alexei Podtelezhnikov <apodtele@gmail.com> |
| 1376 | |
| 1377 | * src/smooth/ftgrays.c (gray_{find,set}_cell): Remove dubious code. |
| 1378 | |
| 1379 | 2016-09-11 Alexei Podtelezhnikov <apodtele@gmail.com> |
| 1380 | |
| 1381 | [smooth] Fix valgrind warning and reoptimize. |
| 1382 | |
| 1383 | The algorithm calls `gray_set_cell' at the start of each new contour |
| 1384 | or when the contours cross the cell boundaries. Double-checking for |
| 1385 | that is wasteful. |
| 1386 | |
| 1387 | * src/smooth/ftgrays.c (gray_set_cell): Remove check for a new cell. |
| 1388 | (gray_convert_glyph): Remove initialization introduced by 44b172e88. |
| 1389 | |

| 1399 | data, not earlier. |
| 1400 | |

| 1402 | after creating the map so that... |
| 1403 | |
| 1404 | * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): ... this function |
| 1405 | can be used before and after setting up `sbit_strike_map'. |

| 1407 | (tt_sbit_decoder_init, tt_face_load_sbix_image): Map strike index. |

| 1413 | [ftfuzzer] Minor improvements. |
| 1414 | |
| 1415 | * src/tools/ftfuzzer/ftfuzzer.cc (LLVMFuzzerTestOneInput): Ignore |

| 1417 | Use better values for call to `FT_Set_Char_Size'. |
| 1418 | |
| 1419 | 2016-09-09 Werner Lemberg <wl@gnu.org> |
| 1420 | |
| 1421 | [sfnt] Don't provide (completely) broken strike data. |
| 1422 | |
| 1423 | FreeType tries to sanitize strike header data; we now reject |
| 1424 | completely broken ones. |
| 1425 | |
| 1426 | * include/freetype/internal/tttypes.h (TT_FaceRec): New |
| 1427 | `sbit_strike_map' array pointer. |
| 1428 | |
| 1429 | * src/base/ftobjs.c (FT_Match_Size): Reject matches where either |
| 1430 | width or height would be zero. |
| 1431 | Add tracing message in case of error. |
| 1432 | |
| 1433 | * src/sfnt/sfobjs.c (sfnt_load_face): Populate `sbit_strike_map', |
| 1434 | only using (more or less) valid strike header data for |
| 1435 | FT_Face's `available_sizes' array. |
| 1436 | (sfnt_done_face): Updated. |
| 1437 | |
| 1438 | * src/sfnt/ttsbit.c (tt_face_set_sbit_strike): Use |
| 1439 | `sbit_strike_map'. |
| 1440 | (tt_face_load_strike_metrics): Improve tracing. |
| 1441 | |
| 1442 | * src/truetype/ttdriver.c (tt_size_select): Use `sbit_strike_map'. |

| 1586 | `libfreetype.a' gets searched in both `objs' (for the development |
| 1587 | build) and `objs/.libs' (for a normal build which uses libtool). |
| 1588 | (LIBS): Add missing libraries. |

| 1599 | sanity test for glyph variation array header size. |
| 1600 | Always set stream position before reading packed x and y deltas. |
| 1601 | Fix thinko w.r.t. `localpoints' array. |
| 1602 | |
| 1603 | 2016-09-03 Werner Lemberg <wl@gnu.org> |
| 1604 | |
| 1605 | [ftrandom] Various fixes. |
| 1606 | |
| 1607 | * src/tools/ftrandom/ftrandom.c (GOOD_FONTS_DIR): Provide better |
| 1608 | default. |
| 1609 | (error_fraction): Make it of type `double' to work as advertized – |
| 1610 | this was completely broken. |
| 1611 | Update all related code. |
| 1612 | (error_count, fcnt): Make it unsigned to fix compiler warnings. |
| 1613 | Update all related code. |
| 1614 | (fontlist): Change `len' member to `long' to fix compiler warnings. |
| 1615 | (FT_MoveTo, FT_LineTo, FT_ConicTo, FT_CubicTo, abort_test): Tag |
| 1616 | unused variables. |
| 1617 | (TestFace, FindFonts, copyfont, do_test): Fix compiler warnings. |

| 1627 | 2016-09-03 Werner Lemberg <wl@gnu.org> |
| 1628 | |
| 1629 | [base] Avoid negative bitmap strike dimensions (#48985). |
| 1630 | |
| 1631 | * src/base/ftobjs.c (FT_Open_Face): Check whether negation was |
| 1632 | actually successful. For example, this can fail for value |
| 1633 | -32768 if the type is `signed short'. If there are problems, |
| 1634 | disable the strike. |
| 1635 | |
| 1636 | 2016-09-03 Werner Lemberg <wl@gnu.org> |
| 1637 | |
| 1638 | [cff] Avoid null pointer passed to FT_MEM_COPY (#48984). |
| 1639 | |
| 1640 | * src/cff/cffload.c (cff_index_get_name): Check `byte_len'. |
| 1641 | |
| 1642 | 2016-09-02 Werner Lemberg <wl@gnu.org> |
| 1643 | |
| 1644 | [unix] Enable 64bit support in file system access (#48962). |
| 1645 | |

| 1647 | |
| 1648 | 2016-09-02 Werner Lemberg <wl@gnu.org> |
| 1649 | |
| 1650 | [sfnt] Avoid left shift of negative value (#48980). |
| 1651 | |
| 1652 | * src/sfnt/ttsbit.c (tt_sbit_decoder_load_bit_aligned): Use unsigned |
| 1653 | constant. |
| 1654 | |
| 1655 | 2016-09-02 Werner Lemberg <wl@gnu.org> |
| 1656 | |

| 1665 | |
| 1666 | * docs/CHANGES: Updated. |
| 1667 | |
| 1668 | 2016-09-01 Alexei Podtelezhnikov <apodtele@gmail.com> |
| 1669 | |
| 1670 | [smooth] Simplify span rendering more. |
| 1671 | |
| 1672 | It turns out that there is significant cost associated with `FT_Span' |
| 1673 | creation and calls to `gray_render_span' because it happens so |
| 1674 | frequently. This removes these steps from our internal use but leaves |
| 1675 | it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain |

| 1966 | |
| 1967 | GETVARIATION[], opcode 0x91 |
| 1968 | This opcode pushes normalized variation coordinates for all axes |
| 1969 | onto the stack (in 2.14 format). Coordinate of first axis gets |
| 1970 | pushed first. |
| 1971 | |
| 1972 | GETINFO[], selector bit 3 |
| 1973 | If GX variation support is enabled, bit 10 of the result is set |
