Method, system, and program for error checking raster objects

摘要

Disclosed is a method, system, and program for error checking raster objects including pixel information for a print job. A plurality of raster objects form the print job. A raster object is received including sequence information indicating an ordering of the raster object with respect to other raster objects in the print job. A determination is made from the sequence information as to whether the raster object is received in a correct order with respect to other raster objects in the print job. This ensures that the pixel information for the raster object is intended for a current pixel line being processed. An indication of error status is made if the sequence information indicates that the raster object was not received in the correct order with respect to the other raster objects in the print job.
