ABSTRACT:
Systems and methods used for font filtering may also be used to perform texture blits. Texture data is read in blocks that are coarsely aligned. Font engines may be used to align the texture data as specified by a copy (blit) instruction to provide a finely aligned region of the texture data within a font filter footprint. The finely aligned region is then bilinearly filtered using a “nearest” mode to provide the bit aligned region of the texture map specified by the copy instruction.
