ABSTRACT:
A drawing processing apparatus is provided to solve the problems in which pixels of a drawing primitive with sub-pixel information may have an increased amount of data causing a burden on implementation. A setup processing unit sets up various parameters to allow a digital differential analyzer (DDA) to process the stream of a drawing primitive supplied from a primitive input unit. The DDA performs DDA processing on the drawing primitive supplied from the setup processing unit for conversion into pixel data. The DDA performs the DDA processing on a per rectangular pixel set basis along a scan line to output the pixel data of the drawing primitive on a per rectangular pixel set basis. A compression encoding unit encodes the sub-pixel information of each pixel contained in the rectangular pixel set by run length encoding for output to a FIFO buffer.
