This generalizes magic outline shifts that make Harmony LCD rendering work in terms of precise two-dimensional RGB subpixel positions. These coordinates are now set in time of the `smooth' module initialization and later used to shift a glyph outline for rendering. FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V use the same coordinates. The letter, however, rotates them before using. The LCD bitmap padding is also calculated using these coordinates. * include/freetype/internal/ftobjs.h (FT_LibraryRec): New array field `lcd_geometry'. * src/base/ftlcdfil.c (ft_lcd_padding): Reworked. * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): Updated accordingly. * src/smooth/ftsmooth.c [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING] (ft_smooth_init): Initialize `lcd_geometry'. (ft_smooth_render_generic): Formalize outline shifts. |
