Abstract
Methods are described for sequentially rendering fonts at multiple bit depths while reducing differences in visual appearance between the fonts rendered at different bit depths. The same hinting may be used for rendering the font at two different bit depths. Methods for reducing artifacts including edge artifacts also are described, including the use of font masks for updating electro-optic displays.
