|
c9c32631 | 2022-09-22 20:40:21 | [base] Clean up the bitmap flow control. * src/base/ftbitmap.c (FT_Bitmap_Copy): Flip the copy if its pitch is trully opposite, zero is not a positive value. (FT_Bitmap_Convert): Set negative pitch as needed, accept negative alignment values. | |
|
c456eeb4 | 2022-09-22 15:09:17 | [base] Discard and recreate bitmaps for copying and converting. Reusing target bitmaps for copying and converting is permitted. It is, however, pointless to preserve their content before overwriting. Free- malloc might be faster than realloc. * src/base/ftbitmap.c (FT_Bitmap_Copy, FT_Bitmap_Convert): Free an old buffer and create a new one. | |
 |
3d77756e | 2022-01-27 08:34:48 | [sfnt] Improve sRGB constants. * src/base/ftbitmap.c (ft_gray_for_premultiplied_srgb_bgra): Use slightly more precise values. Fixes #1018. | |
|

|
49270c17 | 2021-09-14 21:32:43 | Replace boolean allocation macros with MEM ones. * src/base/ftbitmap.c (FT_Bitmap_Copy): Use MEM-macro. * src/base/ftobjs.c (ft_glyphslot_alloc_bitmap): Ditto. * src/bzip2/ftbzip2.c (ft_bzip2_alloc): Ditto. * src/cache/ftccache.c (ftc_cache_init): Ditto * src/gzip/ftgzip.c (ft_gzip_alloc): Ditto. * src/psnames/psmodule.c (ps_unicodes_init): Ditto. * src/sfnt/sfobjs.c (sfnt_load_face): Ditto. * src/sfnt/ttload.c (tt_face_load_name): Ditto. | |

a6adb256 | 2020-12-02 14:15:07 | * src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`. This ensures good logging output, with all lines having a proper prefix (if requested). | |
 |
53be1753 | 2020-07-28 07:33:40 | Fix `-Wformat' compiler warnings. * src/*: Fix format specifiers. * builds/unix/ftsystem.c (FT_Stream_Open): Ditto. | |
|
16586859 | 2020-06-13 21:15:45 | Remove redundant inclusion of `ft2build.h'. * */*: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'. | |
 |
e1339133 | 2020-06-08 13:31:55 | Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation. | |

|
9f6ed105 | 2019-04-22 08:10:56 | * src/base/ftbitmap.c (FT_Bitmap_Blend): Check target pitch. Problem reported by Sender Ghost <lightside@gmx.com>. | |
|
4d51f78d | 2019-02-23 11:21:48 | More documentation updates. In particular, mark the new behaviour of `FT_LOAD_COLOR' as experimental. | |
|
6ab36880 | 2019-02-23 11:18:39 | * src/base/ftbitmap.c (FT_Bitmap_Blend): No fractional offsets. The function only provided a framework without an actual implementation, which this commits removes. | |

|
29f05fd0 | 2018-07-04 11:49:47 | Fix 32bit build warnings (#54239). * src/base/ftbitmap.c (FT_Bitmap_Blend): Add casts to avoid signed vs. unsigned comparisons. * srb/sfnt/ttcolr.c (tt_face_get_colr_layer): Ditto. | |
|

|
9ac9060d | 2018-06-03 09:01:17 | [GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git. | |
|
3b88576b | 2018-04-22 17:22:35 | [base] Fix bitmap emboldening. Bug introduced after release 2.8. * src/base/ftbitmap.c (ft_bitmap_assure_buffer): We use `FT_QALLOC_MULT', which doesn't zero out the buffer. Adjust the bitmap copying code to take care of this fact. | |
|
c2e2a8e5 | 2018-04-22 17:13:50 | Revert "[base] Fix bitmap copying where the new pitch is smaller." This reverts commit c0f1adedcfaad4f7d2fe912ff4b2933845d61d93. | |
|
c0f1aded | 2018-04-22 11:44:24 | [base] Fix bitmap copying where the new pitch is smaller. * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Handle it. | |

|
e1090c60 | 2017-12-08 09:54:36 | Fix access to uninitalized memory (#52613). Also reported as https://bugs.chromium.org/p/chromium/issues/detail?id=791317 * src/base/ftbitmap.c (ft_bitmap_assure_buffer): If increasing the bitmap size needs a larger bitmap buffer, assure that the new memory areas are initialized also. | |
|
87ddad20 | 2017-12-04 20:43:30 | Update or fix links to use the https protocol instead of http. | |
|
a3dd6d99 | 2017-09-05 23:02:04 | Fix multiple calls of `FT_Bitmap_Convert'. The documentation of `FT_Bitmap_Convert' says that multiple calls do proper reallocation of the target FT_Bitmap object. However, this failed for the sequence non-empty bitmap empty bitmap non-empty bitmap Reason was that `FT_Bitmap_Convert' only reallocated the bitmap buffer if it became too small; it didn't make the buffer smaller. For an empty bitmap following a non-empty one, only the buffer dimension got set to zero, without deallocation. If the next call was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was triggered. * src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target buffer to the correct size. * docs/CHANGES: Document it. | |
|
f0898b92 | 2017-08-25 21:40:01 | Swap `ALLOC_MULT' arguments (#51833). * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Updated. * src/winfonts/winfnt.c (FNT_Load_Glyph): Updated. * src/raster/ftrend1.c (ft_raster1_render): Updated. | |

|
b3500af7 | 2014-11-19 21:28:21 | Change some fields in `FT_Bitmap' to unsigned type. This doesn't break ABI. * include/ftimage.h (FT_Bitmap): Make `rows', `width', `num_grays', `pixel_mode', and `palette_mode' unsigned types. * src/base/ftbitmap.c: Updated. (FT_Bitmap_Copy): Fix casts. * src/cache/ftcsbits.c, src/raster/ftraster.c, src/sfnt/pngshim.c: Updated. | |

760d342d | 2013-05-29 11:36:18 | Add support for color embedded bitmaps (eg. color emoji). A new load flag, FT_LOAD_COLOR, makes FreeType load color embedded-bitmaps, following this draft specification https://color-emoji.googlecode.com/git/specification/v1.html which defines two new SFNT tables, `CBDT' and `CBLC' (named and modeled after `EBDT' and `EBLC', respectively). The color bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA pre-multiplied sRGB images. If PNG support is available, PNG color images as defined in the same proposed specification are supported also. Note that color bitmaps are converted to grayscale if client didn't ask for color. * builds/unix/configure.raw: Search for libpng. Add `--without-png' option. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_PNG): New macro. * include/freetype/freetype.h (FT_LOAD_COLOR): New load flag. * include/freetype/ftimage.h (FT_Pixel_Mode): Add `FT_PIXEL_MODE_BGRA'. * include/freetype/tttags.h (TTAG_CBDT, TTAG_CBLC): New tags. * src/base/ftbitmap.c (FT_Bitmap_Embolden): Updated. (ft_gray_for_premultiplied_srgb_bgra): New function. (FT_Bitmap_Convert): Handle FT_PIXEL_MODE_BGRA. * src/sfnt/pngshim.c, src/sfnt/pngshim.h: New files. * src/sfnt/sfnt.c: Include `pngshim.c'. * src/sfnt/ttsbit.c: Include FT_BITMAP_H and `pngshim.h' (tt_face_load_eblc): Load `CBLC'. (tt_sbit_decoder_init): Load `CBDT'. (tt_sbit_decoder_alloc_bitmap): Pass load flags to select between color and grayscale bitmaps. Set `num_grays'. This is used by `ftview' to choose the blending algorithm. (tt_sbit_decoder_load_byte_aligned, tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_compound, tt_sbit_decoder_load_image): Pass load flag. s/write/pwrite/. Don't call `tt_sbit_decoder_alloc_bitmap'. Updated. (tt_sbit_decoder_load_png) [FT_CONFIG_OPTION_USE_PNG]: New function. (tt_sbit_decoder_load_bitmap): Pass load flag. Handle new glyph formats 17, 18, and 19. Call `tt_sbit_decoder_alloc_bitmap'. Flatten color bitmaps if necessary. (tt_face_load_sbit_image): Updated. * src/sfnt/rules.mk (SFNT_DRV_SRC): Add `pngshim.c'. * docs/CHANGES: Updated. | |
|
059bc335 | 2013-03-14 10:27:35 | */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op. | |

38e82be1 | 2005-05-30 19:22:44 | * include/freetype/ftbitmap.h (FT_Bitmap_Embolden): Minor documentation improvements. * include/freetype/ftoutln.h (FT_Outline_Embolden): Fix typos. * src/base/ftbitmap.c (FT_Bitmap_Embolden): Add support for bitmap of pixel_mode FT_PIXEL_MODE_GRAY2 or FT_PIXEL_MODE_GRAY4. If xstr is larger than 8 and bitmap is of pixel_mode FT_PIXEL_MODE_MONO, set xstr to 8 instead of returning error. | |

71d76281 | 2005-05-30 07:54:20 | * src/base/ftbitmap.c (FT_Bitmap_Embolden): Fix emboldening bitmap of mode FT_PIXEL_MODE_GRAY. Also add support for mode FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V. (ft_bitmap_assure_buffer): FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V should have ppb (pixel per byte) 1. Zero the padding when there's no need to allocate memory. * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle slot->advance too. More suited emboldening strength. | |

b9ee7370 | 2005-05-20 21:52:19 | * docs/CHANGES: Updated. * src/base/ftbitmap.c: Don't include FT_FREETYPE_H and FT_IMAGE_H but FT_BITMAP_H. (FT_Bitmap_Copy): New function (from ftglyph.c). * include/freetype/ftbitmap.h (FT_Bitmap_Copy): New public definition. * src/base/ftglyph.c: Include FT_BITMAP_H. (ft_bitmap_copy): Move to ftbitmap.c. (ft_bitmap_glyph_init): Remove `memory' variable. Create new bitmap object if FT_GLYPH_OWN_BITMAP isn't set. (ft_bitmap_glyph_copy): Use FT_Bitmap_Copy. (ft_bitmap_glyph_done): Use FT_Bitmap_Done. (ft_outline_glyph_init): Use FT_Outline_Copy. * src/base/ftoutln.c (FT_Outline_Copy): Handle source == target. (FT_Outline_Done_Internal): Check for valid `memory' pointer. (FT_Outline_Translate, FT_Outline_Reverse, FT_Outline_Render, FT_Outline_Transform): Check for valid `outline' pointer. * src/base/ftobjs.c (FT_New_GlyphSlot): Prepend glyph slot to face->glyph, otherwise a new second glyph slot cannot be created. (FT_Done_GlyphSlot): Fix memory leak. (FT_Open_Face): Updated -- face->glyph is already managed by FT_New_GlyphSlot. * src/type42/t42objs.c (T42_GlyphSlot_Done): Updated. | |
