ABSTRACT:
Image content may be generated in high resolution by performing raster operations, and half-toning is then performed on the image content. Due to such a sequence, a substantially consistent image may be generated on different printers irrespective of the degree of half-toning. Another aspect of the present invention enables the computation requirements to be reduced by storing in a temporary buffer the image data (paint, destination, source) used multiple times.
