Abstract

Methods disclosed permit the identification of frame buffer pixels for trapping. In some embodiments, flags associated with pixels in the frame buffer may be used to provide an indication of pixels for trapping. A first bit in a flag associated with a pixel may be set when the pixel is painted. In some embodiments, the method discloses a process for setting the value of a second bit in the flag to determine if the pixel associated with the flag lies on an object boundary. The pixel is identified as a candidate for trapping based on the value of the at least one flag.
