Abstract:
1. A method of generating outputs for run length encoded constant color data which can be sent to a trap generator comprising the steps of: first determining the maximum number x of pixels which the trap generator may change in color, placing 2x scanlines in run length encoded form into a buffer, inspecting the run lengths in each scanline to determine the next run length end in any one of the 2x scan lines, and taking this end as the current end of segment for all scanlines, determining a center point at the intersection of the line between two scanlines and the line connecting the current end of all scanline segments, and determining a square of pixels all of which are adjacent the center point, determining the color of any two pixels in the square, and sending the number x and the colors of the two pixels to the trap generator to determine the trap color.
