Title: Magnifying/reducing method for font character
Inventor: ITO MASAKAZU
IPC: G06F17/21
Filed: 1989-12-15
Abstract: PURPOSE:To perform the magnification/reduction of a font character without performing interpolation processing by dividing a font character into frames, and judging whether or not it is the effect dot or ineffective dot of the font character after converting with the area ratio of the effective dot in respective frame. CONSTITUTION:It is assumed that the font character of (8X8) is magnified to the one of (10X10). At such a case, the area exclusive rate of the effective dot in respective uniform frame of the font character of (10X10) constitution for the font character of (8X8) constitution is found, and such comparison whether or not it exceeds prescribed N percent is performed. When a result of comparison exceeds the N percent, it is processed that the whole of the frame is effective, and when it is less than the N percent, it is processed that the frame is ineffective. Thereby, since each dot can be judged whether it is effective or ineffective, no interpolation processing is required.
