ABSTRACT:
A method for smooth trapping of an object containing run length encoded image pixel data, includes collecting a number of scanlines of run length encoded pixel data equal to 2M in a buffer, wherein M is a line width trap threshold; determining those runs within the collected scanlines that require trapping, wherein a run is a portion of a scanline; if trapping is required in the fast scan direction and the length of the run requiring trapping is less than M, reducing the width of the trap region by a prorated percent. If trapping is required in the slow scan direction, and the number of runs above and below the run to be trapped is less than M, reducing the number of runs above and below the run to be trapped by a prorated percentage.
