Abstract
Systems, methods, and computer-readable media are disclosed for dynamic contrast adjustment for glyph rendering. Example methods may include rendering a first glyph associated with a font in a first font size, increasing a first contrast of the first glyph in the first font size by adjusting a first grayscale value associated with the first glyph in the first font size to generate an adjusted first grayscale value, and storing the adjusted first grayscale value in a grayscale mapping table associated with the font, the grayscale mapping table comprising a default grayscale value for the first glyph in a second font size. Example methods may include generating a font file comprising the first glyph and the grayscale mapping table.
