* [GSoC] src/*.*: Convert block comments to `light' style.Werner Lemberg2018-06-031-16/+16
| | | | | | | | | | | 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.
* [base] Fix bitmap emboldening.Alexei Podtelezhnikov2018-04-221-4/+6
| | | | | | | | 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.
* Revert "[base] Fix bitmap copying where the new pitch is smaller."Werner Lemberg2018-04-221-44/+14

* Fix multiple calls of `FT_Bitmap_Convert'.Werner Lemberg2017-09-051-2/+1
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* */*: Use `FT_THROW'.Werner Lemberg2013-03-141-11/+13
| | | | | | | | | | 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.
