Abstract: Disclosed is a method, system, and program for receiving line work data and control data for pixels on a sheet from objects. The control data for one pixel indicates whether to use the line work color data for the pixel or contone raster object for the pixel. Further, multiple objects may provide line work data and control data for a same pixel. Line work and control data are simultaneously decompressed for a same set of pixels from the multiple objects and decompressed line work and control data are simultaneously aligned for a same set of pixels from the multiple objects. The simultaneously aligned line work and control data for the pixel from the multiple objects are buffered in a third buffer.
