ABSTRACT:
An improved method for displaying a character on a raster device at relatively low resolution by identifying regions of the character that improperly touch other regions of the character, and then modifying the display of that character to move or delete pixels which decrease legibility of the character, by (1) enumerating the pixels in an order determined by the path topology, (2) searching for sequences of pixels corresponding to a pointed feature in the character that undesirably touches other parts of the character, and (3) editing the bitmap to remove such contacts.
