METHOD, SYSTEM, PROGRAM, AND DATA STRUCTURE FOR GENERATING RASTER OBJECTS

摘要

A method, system, program, and data structure for generating raster objects. A plurality of input contone and line work objects are received containing contone or line work data for at least one pixel on a sheet. For each input contone object, at least one output contone objec t is generated including color data for each pixel in the input contone object. For each input line work object, at least one output line work object is generated including color data for each pixel in the input line work object. Control data, encoded to indicate selection of pixel data from the output li ne work object or from a highest priority output contone object, or selection of transparency, is generated for each pixel and used to select color data from the output line work object or output contone object for pixel data to send to an output device to render the pixel data.
