Programmable mapping of lower resolution digital data to a higher resolution output device

摘要

Lower resolution format data (30) is synthesized to a higher resolution format (126) for rendering on a higher resolution output device, such as a laser printer (14), by selecting and using synthesis templates (126). The synthesis templates represent unique configurations of a plurality of pixel data in the higher resolution format into which the lower resolution format data is to be synthesized. A working pixel (130) is identified from the lower resolution format data, a synthesis template (126) is selected, and then a subset of the synthesis template pixel data is substituted for the working pixel for rendering on the output device in the higher resolution format for a current scan pass. The working pixel is identified in the lower resolution data by recognizing a configuration of a plurality of pixel data adjacent the working pixel, such as with RET (124). The synthesis template comprises at least a two by two cell matrix for pixel placement in the higher resolution format. The synthesis template pixel placement is formed to provide an apparent merge of the pixel data in the higher resolution format with the adjacent pixel data of the lower resolution format data
