Abstract
Aspects of the present invention relate to systems and methods for generating rendered data for printing. According to a first aspect of the present invention, a master stencil may be formed from individual print-object stencils. The master stencil may provide a mapping such that rendered print data may be generated at a pixel without multiple renditions at each pixel for each print object. According to a second aspect of the present invention, the master stencil may provide a mapping such that processing operations may be minimized at each pixel. According to a third aspect of the present invention, individual print-object stencils may be processed serially at each line, or spatial portion. Print-object stencils may be processed in z-order for each line, or spatial portion, and pixels which overlap multiple print objects may be overwritten. According to another aspect of the present invention, a master stencil may be generated while rendering print data. Accordingly, print-object stencils may be processed serially in reverse z-order.
