Abstract:
1. An image processing apparatus comprising: a receiver, configured to receive a drawing command; a determiner, configured to determine attribute types of drawing objects contained in the drawing command; a holding unit, configured to hold an attribute information table, which indicates correspondence of the determined attribute types to an attribute signal having M bits; a rasterization section, configured to rasterize the drawing objects to generate a bitmap image, and configured to generate attribute signals, each of which has M bits and corresponds to each pixel of the bitmap image with reference to the attribute information table; a data storage, configured to store the bitmap image and the attribute signals; and an image processor, configured to convert the attribute signals stored in the data storage to attribute signals each of which has N bits with reference to the attribute information table, and to perform image processing on the bitmap image stored in the data storage with reference to the attribute signals each of which has N bits so as to print the bitmap image on which the image processing is performed by an image output unit, wherein M and N are positive integers, and wherein N is greater than M.
