摘要
PURPOSE:To display characters fast by generating font data specification information according to data which are described in page description language, and referring to a cache or data base and generating a font contour before raster image processing. CONSTITUTION:When the data which are described in the page description language are inputted from a host, a raster image(RIP) module 12 executes application software 50 to generate the font data specification information for obtaining font data on characters in the data. A font control means 54 accesses the font data storage area 60 of the cache according to the font data specification information to generate font data according to contour data. When no contour is present, the data base 22 is accessed to fetch contour data and font data is generated according to the contour data. At the same time, the fetched contour data are stored in a 1st storage means. The font contour is generated before the raster image processing to display and print characters at a high speed.
