Abstract
This invention offers a font processor which performs thinning processing, standard processing and bolding processing in outline font according to a resolution level of an output apparatus. According to this invention, a rasterizer generates a raster image in a first area from the outline font, which is stored in a font memory. An outline producer produces an outline image in a second area according to an outline width, which is determined by an outline width determiner. An operation unit makes an logical operation of the raster image and the outline image, and generates an thinned or bolded raster image.
