| 99 | [base] Remove a check for resource ID in the resource fork driver. |
| 100 | |
| 101 | LastResort.dfont has a marginal resource ID 0xFFFF for sfnt |
| 102 | resource. Inside Macintosh: More Macintosh Toolbox, `Resource IDs' |
| 103 | (1-46), tells that some IDs are reserved and should not be used. |
| 104 | FreeType2 just uses resource ID to sort the fragmented resource. |
| 105 | To accept the marginal fonts, the checking is removed. |
| 106 | |
| 107 | * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id |
| 108 | validity check, fix a trace message format. |
| 109 | |
| 110 | 2017-09-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| 111 | |
| 112 | [sfnt, truetype] Register the tags for marginal fonts. |
| 113 | |
| 114 | The first 32bit of standard TrueType variants is 0x00010000, |
| 115 | `OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac |
| 116 | OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources |
| 117 | starting 0xA5 followed by `kbd' or `lst'. Considering the following |
| 118 | data could be parsed as conventional TrueType fonts, the header |
| 119 | checking is updated to allow these tags. It seems that recent Mac |
| 120 | OS X has already switched to normal TTF for these fonts. |
| 121 | |
| 122 | See the discussion at |
| 123 | http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0 |
| 124 | |
| 125 | * include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header |
| 126 | tags for Keyboard.dfont and LastResort.dfont. |
| 127 | * src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource |
| 128 | starts with TTAG_0xA5kbd or TTAG_0xA5lst. |
| 129 | * src/truetype/ttobjs.c (tt_face_init): Accept the face with the |
| 130 | format tag is TTAG_0xA5kbd or TTAG_0xA5lst. |
| 131 | |
| 132 | 2017-09-05 Werner Lemberg <wl@gnu.org> |
| 133 | |
| 134 | Fix multiple calls of `FT_Bitmap_Convert'. |
| 135 | |
| 136 | The documentation of `FT_Bitmap_Convert' says that multiple calls do |
| 137 | proper reallocation of the target FT_Bitmap object. However, this |
| 138 | failed for the sequence |
| 139 | |
| 140 | non-empty bitmap |
| 141 | empty bitmap |
| 142 | non-empty bitmap |
| 143 | |
| 144 | Reason was that `FT_Bitmap_Convert' only reallocated the bitmap |
| 145 | buffer if it became too small; it didn't make the buffer smaller. |
| 146 | For an empty bitmap following a non-empty one, only the buffer |
| 147 | dimension got set to zero, without deallocation. If the next call |
| 148 | was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was |
| 149 | triggered. |
| 150 | |
| 151 | * src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target |
| 152 | buffer to the correct size. |
| 153 | |
| 154 | * docs/CHANGES: Document it. |
| 155 | |
| 156 | 2017-09-05 Werner Lemberg <wl@gnu.org> |
| 157 | |
| 158 | [bdf] Fix size and resolution handling. |
| 159 | |
| 160 | * src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if |
| 161 | `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are |
| 162 | missing. |
| 163 | |
| 164 | * docs/CHANGES: Document it. |

| 218 | |
| 219 | [sfnt] Speed up PNG image loading. |
| 220 | |
| 221 | This reduces the overhead of `premultiply_data' by 60%. |
| 222 | |
| 223 | * src/sfnt/pngshim.c (premultiply_data): Provide code which uses |
| 224 | gcc's (and clang's) `vector_byte' attribute to process 4 pixels at a |
| 225 | time. |
| 226 | |

| 228 | |
| 229 | [sfnt, truetype] Improve handling of missing sbits. |
| 230 | |
| 231 | Requested by Behdad. |
| 232 | |
| 233 | Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain |
| 234 | entries in the bitmap strike(s) for empty glyphs. Instead, they |
| 235 | rely that a space glyph gets created from the font's metrics data. |
| 236 | This commit makes FreeType behave accordingly. |
| 237 | |
| 238 | * include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error |
| 239 | code. |
| 240 | |
| 241 | * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes |
| 242 | to make a distinction between a missing bitmap in a composite and a |
| 243 | simple missing bitmap. |
| 244 | |
| 245 | * src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a |
| 246 | bitmap-only font), synthesize an empty bitmap glyph if metrics are |
| 247 | available. |
| 248 | |
| 249 | 2017-08-10 Werner Lemberg <wl@gnu.org> |
| 250 | |
| 251 | [base] Minor API improvement for default variation axis setting. |
| 252 | |
| 253 | * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, |
| 254 | FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, |
| 255 | FT_Set_Var_Blend_Coordinates): Allow coords==NULL if num_coords==0. |
| 256 | |
| 257 | * docs/CHANGES: Updated. |
| 258 | |
| 259 | 2017-08-08 Werner Lemberg <wl@gnu.org> |
| 260 | |
| 261 | [psnames] Really fix issue #49949. |
| 262 | |
| 263 | We now use a separate preprocessor macro to handle both definition |
| 264 | and declaration of the glyph name arrays. |
| 265 | |
| 266 | * src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro. |
| 267 | |
| 268 | * src/tools/glnames.py (StringTable::dump, |
| 269 | StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'. |
| 270 | (dump_encoding): Ditto. |
| 271 | (main): Use `wb' mode for writing the output file, which works on |
| 272 | Windows also. |
| 273 | |
| 274 | * src/psnames/pstables.h: Regenerated. |
| 275 | |
| 276 | 2017-08-08 Alexei Podtelezhnikov <apodtele@gmail.com> |
| 277 | |
| 278 | [smooth] Harmony LCD rendering. |
| 279 | |
| 280 | This is a new technology for LCD-optimized rendering. It capitalizes |
| 281 | on the fact that each color channel grid is shifted by a third of a |
| 282 | pixel. Therefore it is logical to render 3 separate monochrome |
| 283 | bitmaps shifting the outline by 1/3 pixel, and then combine them. |
| 284 | Importantly, the resulting output does not require additional LCD |
| 285 | filtering. |
| 286 | |
| 287 | * src/smooth/ftsmooth.c (ft_smooth_render_generic) |
| 288 | [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized |
| 289 | rendering. |
| 290 | |
| 291 | * include/freetype/ftlcdfil.h, include/freetype/freetype.h, |
| 292 | include/freetype/config/ftoption.h, devel/ftoption.h: Updated |
| 293 | documentation. |
| 294 | |
| 295 | 2017-08-08 Alexei Podtelezhnikov <apodtele@gmail.com> |
| 296 | |
| 297 | * src/smooth/ftsmooth.c (ft_smooth_render_generic): Clean up. |
| 298 | |
| 299 | 2017-08-08 Alexei Podtelezhnikov <apodtele@gmail.com> |
| 300 | |
| 301 | * src/sfnt/ttpost.c (format): Use otspec-compliant versions. |

| 314 | |
| 315 | [base, truetype] New function `FT_Get_Var_Axis_Flags'. |
| 316 | |
| 317 | The reserved `flags' field got a value in OpenType version 1.8.2; |
| 318 | unfortunately, the public `FT_Var_Axis' structure misses the |
| 319 | corresponding element. Since we can't add a new field, we add an |
| 320 | access function. |
| 321 | |
| 322 | * src/base/ftmm.c (FT_Get_Var_Axis_Flags): New function. |
| 323 | |
| 324 | * include/freetype/ftmm.h (FT_VAR_AXIS_FLAG_HIDDEN): New macro. |
| 325 | Updated. |
| 326 | |
| 327 | * src/truetype/ttgxvar.c (TT_Get_MM_Var): Increase allocated memory |
| 328 | of `mmvar' to hold axis flags. |
| 329 | Fill the axis flags array. |
| 330 | |
| 331 | * docs/CHANGES: Updated. |
| 332 | |
| 333 | 2017-08-03 Nikolaus Waxweiler <madigens@gmail.com> |
| 334 | |
| 335 | [truetype] Fix metrics of B/W hinting in v40 mode. |
| 336 | |
| 337 | Phantom points are now saved outside v40 backwards compatibility |
| 338 | mode. This fixes the jumping glyphs when switching between v35 and |
| 339 | v40 monochrome mode. |
| 340 | |
| 341 | * src/truetype/ttgload.c (TT_Hint_Glyph): Fix inversed bool logic. |
| 342 | |
| 343 | 2017-08-03 Nikolaus Waxweiler <madigens@gmail.com> |
| 344 | |
| 345 | [truetype] Do not set any ClearType flags in v40 monochrome mode. |
| 346 | |
| 347 | This fixes weird behavior of instructions that resulted in rendering |
| 348 | differences between v35 and v40 in monochrome mode, e.g., in |
| 349 | `timesbi.ttf'. |
| 350 | |
| 351 | * src/truetype/ttinterp.c (Ins_GETINFO) |
| 352 | [TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Check |
| 353 | `subpixel_hinting_lean'. |

| 368 | [sfnt, truetype] Minor adjustments for OpenType 1.8.2. |
| 369 | |
| 370 | * src/sfnt/sfobjs.c (sfnt_load_face): The units per EM value has now |
| 371 | (tighter) limits. |
| 372 | |
| 373 | * src/truetype/ttgload.c (load_truetype_glyph): The new OpenType |
| 374 | version explicitly allows all negative values for the number of |
| 375 | contours if we have a composite glyph (this is for better backwards |
| 376 | compatibility I guess), but it still recommends value -1. |

| 956 | Handle some integer overflow run-time errors (#46149, #48979). |
| 957 | |
| 958 | This commit (mainly for 32bit CPUs) is the first of a series of |
| 959 | similar commits to handle known integer overflows. Basically, all |
| 960 | of them are harmless, since they affect rendering of glyphs only, |
| 961 | not posing security threats. It is expected that fuzzying will show |
| 962 | up more overflows, to be fixed in due course. |
| 963 | |
| 964 | The idea is to mark places where overflows can occur, using macros |
| 965 | that simply cast to unsigned integers, because overflow arithmetic |
| 966 | is well defined in this case. Doing so suppresses run-time errors |
| 967 | of sanitizers without adding computational overhead. |

| 987 | [cff] s/cf2_floatToFixed/cf2_doubleToFixed/. |
| 988 | |
| 989 | The new name better describes what the macro actually does; |
| 990 | additionally, we don't need a trailing `f' for literals (there was |
| 991 | only a single such instance in the code, but this caused a clang |
| 992 | warning because the macro itself uses `double' literals). |

| 1040 | [smooth] Implement minimal dynamic padding for LCD filtering. |
| 1041 | |
| 1042 | Extra bitmap padding for LCD filtering depends on the filter. The |
| 1043 | default 5-tap filter needs 2 extra subpixels. The light 3-tap filter |
| 1044 | needs only 1 extra subpixel. This space could be already available |
| 1045 | due to rounding. In order to optimize the padding, we now expand |
| 1046 | CBox for the given filter weights before rounding. |
| 1047 | |
| 1048 | This change breaks current Skia (and Firefox). |
| 1049 | |
| 1050 | * include/freetype/internal/ftobjs.h (FT_LibraryRec) |

| 1079 | [autofit] Make autohint warping NORMAL option. |
| 1080 | |
| 1081 | This moves warping option from LIGHT to NORMAL mode. This makes LIGHT |
| 1082 | truly void of hinting in x-direction, with left side bearing never |
| 1083 | changed and right side bearing only altered by advance rounding. |
| 1084 | Therefore, LIGHT is now ready to return fractional advance. As a |
| 1085 | NORMAL option, warping substitutes normal hinting. |

| 1346 | [truetype] Make `IUP' gvar deltas do the same as Apple (#50832). |
| 1347 | |
| 1348 | When points are not touched by gvar interpolation deltas, FreeType |
| 1349 | gave a slightly different result than Apple's CoreText. |
| 1350 | |
| 1351 | The OpenType working group will update the specification to document |
| 1352 | the following behaviour: If the two points with deltas to the `left' |
| 1353 | and `right' of the untouched point have the same coordinate, then |
| 1354 | the inferred delta for the untouched point should be zero. |

| 1431 | [truetype] Do linear scaling for FT_LOAD_NO_HINTING (#50470). |
| 1432 | |
| 1433 | * src/truetype/ttobjs.h (TT_SizeRec): Add field `hinted_metrics' to |
| 1434 | hold hinted metrics. |
| 1435 | Make `metrics' a pointer so that `tt_glyph_load' can easily switch |
| 1436 | between metrics. |
| 1437 | |
| 1438 | * src/truetype/ttdriver.c (tt_size_request): Updated. |
| 1439 | (tt_glyph_load): Use top-level metrics if FT_LOAD_NO_HINTING is |
| 1440 | used. |
| 1441 | |
| 1442 | * src/truetype/ttgload.c (TT_Hint_Glyph, TT_Process_Simple_Glyph, |
| 1443 | TT_Process_Composite_Component, load_truetype_glyph, |
| 1444 | compute_glyph_metrics, TT_Load_Glyph): Updated. |

| 1447 | |
| 1448 | * src/truetype/ttobjs.c (tt_size_reset): Updated. |

| 1451 | |
| 1452 | 2017-04-22 Werner Lemberg <wl@gnu.org> |
| 1453 | |
| 1454 | Add new `slight' auto-hinting mode. |
| 1455 | |
| 1456 | This mode uses fractional advance widths and doesn't scale glyphs |
| 1457 | horizontally, only applying vertical scaling and hinting. |
| 1458 | |
| 1459 | At the same time, the behaviour of the `light' auto-hinter gets |
| 1460 | restored for backward compatibility: Both vertical and horizontal |
| 1461 | scaling is again based on rounded metrics values (this was changed |
| 1462 | in a commit from 2017-03-30 as a side effect). To be more precise, |
| 1463 | the behaviour is restored for TrueType fonts only; for other font |
| 1464 | formats like Type 1, this is a new feature of the `light' hinting |
| 1465 | mode. |
| 1466 | |
| 1467 | * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro. |
| 1468 | (FT_RENDER_MODE_SLIGHT): New render mode. |
| 1469 | |
| 1470 | * include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add |
| 1471 | `autohint_mode' and `autohint_metrics' fields. |

| 1474 | (af_latin_hints_init), src/autofit/aflatin2 (af_latin2_hints_init): |
| 1475 | Updated. |
| 1476 | |
| 1477 | * src/autofit/afloader.c (af_loader_embolden_glyph_in_slot): Use |
| 1478 | `autohint_metrics'. |
| 1479 | (af_loader_load_glyph): s/internal/slot_internal/. |
| 1480 | Initialize `autohint_metrics' and `autohint_mode' depending on |
| 1481 | current auto-hint mode. |
| 1482 | Use `autohint_metrics'. |
| 1483 | Updated. |
| 1484 | |
| 1485 | * src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Updated. |
| 1486 | |

| 2163 | [sfnt, truetype] Always provide default instance. |
| 2164 | |
| 2165 | As documented in the OpenType specification, an entry for the |
| 2166 | default instance may be omitted in the named instance table. In |
| 2167 | particular this means that even if there is no named instance table |
| 2168 | in the font we actually do have a named instance, namely the default |
| 2169 | instance. |
| 2170 | |
| 2171 | For consistency, we always want the default instance in our list of |
| 2172 | named instances. If it is missing, we try to synthesize it. |
| 2173 | |
| 2174 | * src/sfnt/sfobjs.c (sfnt_init_face): Check whether the default |
| 2175 | instance is in the table of named instances. Otherwise adjust |

| 2415 | [autofit] Prevent overlapping blue zones. |
| 2416 | |
| 2417 | Problem reported as |
| 2418 | |
| 2419 | https://github.com/google/fonts/issues/632 |
| 2420 | |
| 2421 | The font in question (Nunito) has values 705 and 713 for the |
| 2422 | reference and overshoot values, respectively, of the first blue |
| 2423 | zone. Blue zone 2, however, has value 710 for both the reference |
| 2424 | and overshoot. At 12ppem, reference and overshoot of blue zone 0 |
| 2425 | becomes 8px, while blue zone 2 becomes 9px. |
| 2426 | |
| 2427 | A peculiarity of this font is that the tops of isolated vertical |
| 2428 | stems like `N' have a slight overshoot also. The auto-hinter tries |
| 2429 | to find the nearest blue zone using the *original* coordinates. For |
| 2430 | vertical stems, this is value 713. For normal horizontal tops like |
| 2431 | in character `E', this is value 710. Since value 713 is mapped to |
| 2432 | 8px but value 710 to 9px, `N' and similar characters are one pixel |
| 2433 | higher than `E', which looks very bad. |
| 2434 | |
| 2435 | This commit sanitizes blue zones to avoid such a behaviour. |
| 2436 | |
| 2437 | * src/autofit/aflatin.c (af_latin_sort_blue): New function. |

| 2467 | [autofit] Use better blue zone characters for lowercase latin. |
| 2468 | |
| 2469 | The number of lowercase characters for computing the top flat blue |
| 2470 | zone value was too small (in most cases only `x' and `z'). If one |
| 2471 | of the two characters has a large serif, say, it can happen that |
| 2472 | FreeType must select between two different values, having a 50% |
| 2473 | chance to use the wrong one. As a result, rendering at larger PPEM |
| 2474 | values could yield uneven lowercase glyph heights. |

| 2860 | |
| 2861 | The change from 2016-09-29 was too radical (except for people using |
