System and method for document rendering employing bit-band instructions

摘要

A system and method for rendering of electronic documents includes interpreting of page description language to generate a series of instruction arrays corresponding to each of a plurality of bands that conjoin to form a rendered document output. Each instruction array includes instructions descriptive of a band of pixels to be generated corresponding to a scanline of an output image. Instructions include one or more image primitives described in the original, electronic document. The system allows for efficient, compact document rendering including multiple or mixed image or text areas that may overlap in an output document.
