ABSTRACT:
A material of displaying a character on a raster device wherein the character is described by means of one or more paths. The crosses where a path intersects horizontal pixel midlines are identified and paired in scan line order as cross pairs. Runs of pixels are identified from the cross pairs. Collisions are identified between two runs of pixels and the repair operation is performed to remove the collision while maintaining the integrity of the character. The most common repair operation is to move or delete one or more of the pixels involved in the collision.
