| [gzip] Support `gzip' encoded header conditionally. |
| |
| In order to support `gzip' encoded header the call to |
| `inflateInit2' was modified in commit 6a92b1fadde26477a9179. |
| However, this code breaks with the outdated internal version |
| of zlib. This is a temporary fix to conditionally support |
| `gzip' encoded header whenever a system installation of zlib |
| is being used. |
| |
| Problem report in |
| |
| https://lists.nongnu.org/archive/html/freetype-devel/2020-02/msg00023.html |
| |
| * src/gzip/ftgzip.c (FT_Gzip_Uncompress): Change the the call to |
| `inflateInit2' depending on whether the system installation is |
| being used or the internal copy. |

| |
| [truetype] Fix state of `FT_Face' for buggy `gvar' tables (#57923). |
| |
| By resetting the blend as implemented with this commit fonts with |
| invalid `gvar' tables may keep calling into `ft_var_load_gvar' from |
| `tt_set_mm_blend' and failing, but the font was invalid anyway and |
| we want to keep seeing the failure in `tt_set_mm_blend'. |
| |
| * src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of |
| offset array once. |
| Allocate arrays after `FT_FRAME_ENTER' (extra check before |
| allocating and avoid needing to free array later if error entering |
| frame). |
| Always call `FT_FRAME_EXIT'. |
| Consistently set counts immediately after array initialized. |
| Reset the blend (particularly `blend->glyphoffsets') on failure. |
| |
| 2020-03-01 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> |

| |
| for more information. |

| (pre) -> (pre>code) |
| (p, .md-typeset p, h4): Remove commented styles. |
| (table.index): Remove unused styles. |

| checked. |
| Also do some sanitizing to avoid a too early exit. |

| The libs which cmake controls are commented out at |
| |
| include/freetype/config/ftoption.h |

| and cmake un-comment each enabled library, but the brotli option was |
| not commented out, therefore `FT_CONFIG_OPTION_USE_BROTLI' remained |

| [sfnt] Support `face->num_faces' for WOFF2 fonts. |
| |
| Set correct value of `face->num_faces' for WOFF2 fonts. This is |

| sfnt stream. |

| |
| 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> |
| |
| [woff2] Avoid too many calls to `FT_REALLOC'. |
| |
| We do this by using `totalSfntSize' as an initial reference, and |
| extending the buffer when required. This reduces rendering time |
| considerably. |
| |
| * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add |
| `totalSfntSize', rename `total_sfnt_size' to `actual_sfnt_size'. |
| |
| * src/sfnt/sfwoff2.c (write_buf): Add parameter `dst_size' to keep |
| track of and update total size of stream. |
| |
| (WRITE_SFNT_BUF, WRITE_SFNT_BUF_AT): Modify macros accordingly. |
| |
| (pad4, store_loca, reconstruct_glyf, reconstruct_hmtx, |
| reconstruct_font): Update parameters to accept `sfnt_size'. |
| |
| (woff2_open_font): Add variable `sfnt_size'. Use WOFF2 header field |
| `totalSfntSize' as initial reference (if value makes sense) and |
| allocate `totalSfntSize' bytes for the sfnt stream. `write_buf' |
| handles reallocation if and when required. Also resize the stream |
| to `actual_sfnt_size' after reconstruction. |
| |
| 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> |
| |
| [woff2] Reconstruct `loca', `hmtx', and swap out stream. |
| |
| Add necessary functions to reconstruct loca and hmtx tables (the two |
| remaining tables that can have a transform). `woff2_open_font' is |
| now capable of loading a woff2 font face. This code may still need |
| more refining and better memory management. |
| |
| * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add total |
| (final) size of sfnt stream. |
| |
| (WOFF2_InfoRec): Add header checksum value. |
| |
| * src/sfnt/sfobjs.c (sfnt_open_font): Change `face_instance_index' |
| parameter to its pointer so its value can be modified by |
| `woff2_open_font'. |
| |
| * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF_AT): New macro to write into |
| sfnt buffer at given position. |
| |
| (write_buf): Add parameter `extend_buf' which allows caller to |
| specify whether buffer should be reallocated before copying data. |
| |
| (WRITE_SFNT_BUF): Updated. |
| |
| (pad4, store_loca, reconstruct_htmx): New functions. |
| |
| (reconstruct_glyf): Calculate loca values and store them. |
| |
| (reconstruct_font): Call `reconstruct_hmtx', write table record |
| entries, and calculate table checksums. Also calculate font |
| checksum and update `checksumAdjustment' entry in head table. |
| |
| (woff2_open_font): Open stream for sfnt buffer, swap out input |
| stream and return. |
| |
| * src/sfnt/sfwoff2.h (woff2_open_font): Modify parameter to accept |
| pointer to `face_index'. |
| |

| |
| [woff2] Reconstruct transformed `glyf' table. |
| |
| Reconstruct `glyf' table if it is transformed in the uncompressed |
| table stream. Also add necessary structures, macros and functions. |
| |
| * include/freetype/internal/wofftypes.h (WOFF2_InfoRec, |
| WOFF2_SubstreamRec, WOFF2_PointRec): New structures. |
| (WOFF2_TableRec): s/OrigLength/dst_length/. |
| |
| * src/sfnt/sfwoff2.c (READ_255USHORT, READ_BASE128): Use |
| `FT_SET_ERROR' to set implicit `error' variable. |
| |
| (WRITE_SHORT): New macro. |
| |
| (N_CONTOUR_STREAM, N_POINTS_STREAM, FLAG_STREAM, GLYPH_STREAM, |
| COMPOSITE_STREAM, BBOX_STREAM, INSTRUCTION_STREAM): New macros to |
| refer to substreams of the transformed `glyf' tables. |
| |
| (Read255UShort, ReadBase128): Return errors set by `FT_READ_XXX' |
| macros. |
| |
| (with_sign, safe_int_addition): New functions to add sign to values |
| based on a flag and perform safe addition respectively. |
| |
| (triplet_decode): Decode variable-length (flag, xCoordinate, |
| yCoordinate) triplet for a simple glyph. See |
| |
| https://www.w3.org/TR/WOFF2/#triplet_decoding |
| |
| (store_points, compute_bbox, composteGlyph_size, reconstruct_glyf): |
| New functions. |
| |
| (reconstruct_font): Call `reconstruct_glyf'. |
| |
| * src/sfnt/sfwoff2.h: Add required constants. |
| |
| * src/sfnt/woff2tags.h: Move out constants to `sfwoff2.h'. |

| [woff2] Copy un-transformed tables to sfnt stream. |
| |
| Copy un-transformed tables to the sfnt stream. |
| |
| * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF): New macro. |
| (write_buf): New function. Extend memory of `dst' buffer and copy |
| bytes from `src'. |
| (compute_ULong_sum): New function. Calculate checksum of table. |
| (reconstruct_font): Change `FT_Byte* sfnt' to `FT_Byte** |
| sfnt_bytes'. This has been done because we reallocate memory to |
| `sfnt' multiple times, which may change the pointer value of `sfnt'. |
| This new pointer must be propogated back to the caller. Same reason |
| for using a double pointer in `write_buf'. |
| |
| * src/sfnt/woff2tags.h (WOFF2_DEFAULT_MAX_SIZE): New macro used for |
| overflow checking. |
| |
| 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> |
| |
| [woff2] Create stream for uncompressed buffer. |
| |
| Uncompressed buffer is now an `FT_Stream'. |
| |
| Perform basic checks and start iterating over tables. |
| |
| * src/sfnt/sfwoff2.c (stream_close, find_table, read_num_hmetrics): |
| New functions. |
| (reconstruct_font): Modify parameters and iterate over tables. |
| (woff2_open_font): Updated. |
| |
| 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> |
| |
| [woff2] Handle TTCs and start reconstructing font. |
| |
| We `handle' TTCs by modifying the `indices' array to point to only |
| those tables that are part of the requested `face_index'. |
| |
| Set and use `num_tables' in `WOFF2_TtcFont'. |
| |
| * src/sfnt/sfwoff2.c (reconstruct_font): New function. |
| (woff2_open_font): Start reconstruction of font. |
| |
| 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> |
| |
| [woff2] Get known tags from function. |
| |
| Change `KnownTags' to a function (`woff2_known_tags'). This avoids |
| introducing a global constant array. This function returns the |
| specified index without *any* checks. The caller must ensure that |
| `index' is within array limits. |
| |
| * src/sfnt/sfwoff2.c (woff2_open_font): Change `KnownTags[...]' |
| notation to `woff2_known_tags( ... )'. |
| |
| * src/sfnt/woff2tags.c: Perform changes. |
| |
| * src/sfnt/woff2tags.h: Update definitions. |

| |
| [woff2] Uncompress Brotli streams and `face_index' support. |
| |
| WOFF2 compressed stream is now uncompressed if Brotli is available. |
| This data is stored in a separate buffer (uncompressed_buf) because |
| it does not contain direct table data. Certain tables have |
| transformations applied to them, and they must be reconstructed |
| before we can write those tables to the SFNT stream. |
| |
| `face_index' is now being passed as a parameter to |
| `woff2_open_font'. |
| |
| * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter |
| `face_instance_index'. |
| |
| * src/sfnt/sfwoff2.c (woff2_uncompress): New function. |

| |
| [psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580). |
| |
| As originally intended, a Type 1 SEAC charstring would be used for |
| an accented glyph (like `acaron' or `uumlaut'), where the advance |
| width of the SEAC glyph is the same as that of the `base' glyph |
| (like `a' or `u'). In this case it is not uncommon for the SEAC |
| glyph to not use an (H)SBW opcode of its own but to rely on the |
| value from the base glyph. |
| |
| However, out-of-spec fonts also use SEAC glyphs for ligatures (like |
| `oe' or `fi'), and in those cases the overall advance width is |

| [smooth] Simplify cubic Bรฉzier flattening. |
| |
| The previous implementation is correct but it is too complex. |
| The revised algorithm is based on the fact that each split moves |
| the control points closer to the trisection points on the chord. |
| The corresponding distances are good surrogates for the curve |
| deviation from the straight line. |
| |
| This cubic flattening algorithm is somewhat similar to the conic |
| algorithm based the distance from the control point to the middle of |
| the chord. The cubic distances, however, decrease less predictably |
| but are easy enough to calculate on each step. |
| |
| The new algorithm produces slightly larger number of splits, which is |
| compensated by its simplicity. The overall rendering performance is |
| improved by 1-2%. The larger number of splits does not necessarily |
| result in higher quality, which stays comparable. |
| |

| condition. |

| |
| Fix invalid function pointer casts. |
| |
| This change should allow Freetype to work on WASM/Emscripten without |
| needing `-s EMULATE_FUNCTION_POINTER_CASTS=1'. |
| |
| * src/autofit/afdummy.c (af_dummy_hints_apply): Fix signature. |
| |
| * src/cid/cidload.c (cid_parse_font_matrix, parse_fd_array, |
| parse_expansion_factor, parse_font_name): Return `void', not |

| [base] Handle numeric overflow (#55827). |
| |
| * src/base/ftglyph.c (FT_Glyph_Get_CBox): Use `FT_PIX_CEIL_LONG'. |
| |
| 2019-03-05 Sebastian Rasmussen <sebras@gmail.com> |
| |
| [psaux] Fix use of uninitialized memory (#55832). |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString): The call to |
| `cf2_arrstack_setCount' may fail because the allocator ran out of |
| memory. When this happens the stack is still written to before the |
| error condition is checked. This means that FreeType writes outside |
| of allocated memory. This commit moves the error check prior to the |
| stack assignment, hence the function now properly returns with an |
| error condition. |
| |
| 2019-02-23 Werner Lemberg <wl@gnu.org> |
| |
| * src/base/ftbitmap.c (FT_Bitmap_Blend): No fractional offsets. |
| |
| The function only provided a framework without an actual |
| implementation, which this commit removes. |
| |
| 2019-02-23 Werner Lemberg <wl@gnu.org> |
| |
| * src/tools/update-copyright-year: Insert `(C)'. |
| |

| |
| 2019-02-02 Nikolaus Waxweiler <madigens@gmail.com> |
| |
| [truetype] Apply MVAR hasc, hdsc and hlgp metrics to current FT_Face metrics. |
| |
| Instead of setting typo or win metrics as the new `FT_Face' metrics |
| indiscriminately, apply only typo deltas to the currently active |
| `FT_Face' metrics. This prevents line height differences when the |
| default outlines were used as the regular face and instances for |
| everything else, for example. |
| |
| * src/truetype/ttgxvar.c (tt_apply_mvar): Implement. |
| |
| 2019-02-02 Nikolaus Waxweiler <madigens@gmail.com> |
| |
| [sfnt] Use typo metrics if OS/2 fsSelection USE_TYPO_METRICS bit is set. |
| |
| If the `OS/2' table exists and `fsSelection' bit 7 |
| (USE_TYPO_METRICS) is set, use the `sTypo*' set of values to compute |
| the `FT_Face's ascender, descender, and height. Otherwise, fall |
| back to old behavior. |
| |
| * src/sfnt/sfobjs.c (sfnt_load_face): Implement. |
| |

| [sfnt] Handle TT fonts having two PostScript font names (#55471). |
| |
| * src/sfnt/sfdriver.c (sfnt_get_name_id): Prefer English over any |
| other language found for PostScript font names. |
| |
| 2019-01-08 Chris Liddell <chris.liddell@artifex.com> |
| |
| [psaux] Fix closepath (#55414). |
| |
| All of the Type 1 path building is done with code common to the |
| revised CFF engine, with the exception of closepath, which was still |
| calling ps_builder_close_contour(), thus previously cached segments |
| were not always written to the path, and glyph corruption, or even |
| invalid outlines were possible. |
| |
| * src/psauc/psinterp.c (cf2_interpT2CharString) <cf2_cmdCLOSEPATH>: |
| Switch to calling `cf2_glyphpath_closeOpenPath'. |
| |

| |
| * src/gxvalid/gxvjust.c (gxv_just_check_max_gid), |
| src/gxvalid/gxvmort.c (gxv_mort_coverage_validate): Use `FT_UNUSED'. |
| |
| 2018-12-11 Werner Lemberg <wl@gnu.org> |
| |
| * src/truetype/ttgload.c (TT_Hint_Glyph): Remove useless test. |
| |
| `control_len' only gets its value from `n_ins' (and vice versa), |
| which is always read as `unsigned short' and thus can't be larger |
| than 0xFFFF. |
| |
| 2018-12-04 Werner Lemberg <wl@gnu.org> |

| [type1,cff] Add FT_{Set,Get}_MM_WeightVector API calls. |
| |

| supports that use. |
| |
| * include/freetype/ftmm.h, src/base/ftmm.c (FT_Set_MM_WeightVector, |

| Fix handling of `FT_Bool'. |
| |
| Before this commit we had code like |
| |
| (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) |
| |
| Since `FT_Bool' is defined to be an `unsigned char', the code |
| evaluated to something like |
| |
| (unsigned char)( 0x8532 & 0x8000) |
| |
| which in turn expanded to |
| |
| (unsigned char)( 0x8000) |

| |
| Improve auto-hinter handling of bitmap fonts (#54681). |
| |
| For bitmap fonts, `FT_Load_Glyph' should either return an error or |
| not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this |
| case `FT_Load_Glyph' calls into the auto-hinter which calls back |
| into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which |
| marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path |
| (even though it doesn't have any path). It appears that the |
| auto-hinter should not be called when the face doesn't have |
| outlines. The current test for using the auto-hinter in |
| `FT_Load_Glyph' checks whether the driver supports scalable |
| outlines, but not if the face supports scalable outlines. |
| |
| * src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have |
| scalable outlines. |

| |
| * src/base/ftobjs.c (ft_glyphslot_preset_bimap): Tiny rounding tweak. |

| [pcf] Replace charmap implementation. |
| |
| PCF comes with charmap lookup table, aka PCF encodings. Using it |

| [base] Introduce `FT_New_Glyph'. |
| |
| This function facilitates access to full capabilities of FreeType |
| rendering engine for custom glyphs. This can be quite useful for |
| consistent rendering of mathematical and chemical formulas, e.g. |
