Patent ID: 8208169

Claim:
A method, comprising: receiving a first Boolean logical exclusive OR raster operation object, the first Boolean logical exclusive OR raster operation object including a raster operation requesting that a first Boolean logical exclusive OR operation be performed; receiving a copy raster operation object, the copy raster operation object including a raster operation requesting a copy operation; receiving a second Boolean logical exclusive OR raster operation object, the second Boolean logical exclusive OR raster operation object including a raster operation requesting that a second Boolean logical exclusive OR operation be performed, the first and second Boolean logical exclusive OR raster operation objects and the copy raster operation object each comprising a PDL object for use in producing a printed image having a plurality of shapes, the plurality of shapes including a first shape and a second shape positioned beneath the first shape in the image, the first shape being transparent such that the first shape and an area of the second shape beneath the first shape in the image to be printed are both visible; determining whether attributes of the second Boolean logical exclusive OR raster operation object match attributes of the first Boolean logical exclusive OR raster operation object; and upon an affirmative determination, selecting shape data associated with either the first or second Boolean logical exclusive OR raster operation object, color data associated with either the first or second Boolean logical exclusive OR raster operation object and mask data associated with the copy raster operation object to render a transparent image, and discarding data from unselected data of either first or second Boolean logical exclusive OR raster operation object.
