ABSTRACT:
A data converting apparatus and process for converting outline representations of a character into its bit mapped form using two buffers one being for the bit mapped form of the character symbol and the other for the chain-code representation of the outline of the character are disclosed. Three steps are utilized in the process. The first step draws the character outline on to the drawing buffer and generates the chain-code representation with flags to indicate contour collisions. The contours are then scanned one more time to add missing flags on the chain-code representation. Finally, the inside part of the contour on the drawing buffer is filled using the chain-code representations of the contour, to provide a filled character.
