Abstract
A character image processing apparatus so adapted that when a typeface and size are specified at generation of a character image, a font of a specific typeface and of a size within predetermined selection limits of a specified size is retrieved from pre-rasterized fonts already developed as bitmap data and stored. In a case where a character image is generated from this font, the character will be generated at a position offset from the position the character of the specified size would have originally occupied. Accordingly, position is corrected in such a manner that the center of the position which a character would have originally occupied and the position of the center of the character generated from the pre-rasterized font will coincide. Further, the selection limits are decided using sizes midway between a stored pre-rasterized font and character sizes one size larger and one size smaller than that of this pre-rasterized font as boundaries.
