When used with subpixel rendering, this results in + sometimes severe color fringes. + + +.. data:: FT_LCD_FILTER_DEFAULT + + The default filter reduces color fringes considerably, at the cost of a + slight blurriness in the output. + + +.. data:: FT_LCD_FILTER_LIGHT + + The light filter is a variant that produces less blurriness at the cost of + slightly more color fringes than the default one. It might be better, + depending on taste, your monitor, or your personal vision. + + +.. data:: FT_LCD_FILTER_LEGACY + + This filter corresponds to the original libXft color filter. It provides high + contrast output but can exhibit really bad color fringes if glyphs are not + extremely well hinted to the pixel grid. In other words, it only works well + if the TrueType bytecode interpreter is enabled and high-quality hinted fonts + are used. + + This filter is only provided for comparison purposes, and might be disabled + or stay unsupported in the future. + |
