ab2599ea | 2017-05-20 00:35:21 | [smooth] Implement minimal dynamic padding for LCD filtering. Extra bitmap padding for LCD filtering depends on the filter. The default 5-tap filter needs 2 extra subpixels. The light 3-tap filter needs only 1 extra subpixel. This space could be already available due to rounding. In order to optimize the padding, we now expand CBox for the given filter weights before rounding. This change breakes current Skia (and Firefox). * include/freetype/internal/ftobjs.h (FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Remove `lcd_extra' field. * src/base/ftlcdfil.c (FT_Library_SetLcdFilterWeights, FT_Library_SetLcdFilter): Remove `lcd_extra' initializations. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Implement dymanic LCD padding. | |

6497b9c5 | 2014-06-13 09:28:00 | Fix compiler warnings. Reported by Wojciech Mamrak <wmamrak@gmail.com>. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage), src/autofit/afmodule.c (af_property_set): Fix `signed' vs. `unsigned' issues. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Make compiler happy. * src/base/ftlcdfil.c (_ft_lcd_filter_fir): Use only four elements for `fir'. Fix `signed' vs. `unsigned' issues. * src/sfnt/sfobjs.c (WRITE_BYTE): Removed, unused. (WRITE_USHORT, WRITE_ULONG): Add proper casts. * src/truetype/ttgload.c (TT_Get_VMetrics): Add proper casts. * src/truetype/ttinterp.c (Ins_DELTAP): Add proper casts for `B1' and `B2'. | |
|
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. | |

460d23f1 | 2010-04-05 08:46:26 | Add new function `FT_Library_SetLcdFilterWeights'. This is based on code written by Lifter <http://unixforum.org/index.php?showuser=11691>. It fixes FreeDesktop bug #27386. * src/base/ftlcdfil.c (FT_Library_SetLcdFilterWeights): New function. * include/freetype/ftlcdfil.h: Updated. * docs/CHANGES: Updated. | |

29c191cd | 2006-11-13 13:03:48 | * src/base/ftlcdfil.c: added support for FT_FORCE_LIGHT_LCD_FILTER and FT_FORCE_LEGACY_LCD_FILTER at compile time. Define these macros when building the library to change the default LCD filter to be used. This is only useful for experimentation | |
|
8765c71b | 2006-11-10 16:49:42 | * include/freetype/ftlcdfil.h, include/internal/ftobjs.h, src/base/ftlcdfilt.c, src/smooth/ftsmooth.c: API change for the LCD filter, the FT_LcdFilter value is a enum describing which filter to apply, new values FT_LCD_FILTER_LIGHT and FT_LCD_FILTER_LEGACY (the latter implements the LibXft original algorithm which produces incredible color fringes for everything except very-well hinted text) * src/autofit/aflatin.c: various tiny improvements that drastically improve the handling of serif fonts and of LCD/LCD_V hinting modes. | |
