Abstract
An image drawing apparatus wherein the processing time and the memory capacity are reduced and jaggy is reduced to improve the image quality. A command received at an image data inputting section is sent to a vector production section, in which, when the command is a font, it is converted into vector data using data stored in a font data storage section. A graphic edge list production section produces, from the vector data, an edge list processed in the magnification of n times. The edge list is referred to in units of n scanning lines by a gray scale processing section, by which a new edge list with which a portion determined to be an edge of a figure is to be drawn in a half tone when necessary is produced. The second edge list is successively processed by a clipping processing section and an edge list merging section and then converted into raster data, which are outputted to an outputting apparatus such as a printer.
