Method, system, program and data structure for generating raster objects

摘要

Disclosed is a method, system, program, and data structure for generating raster objects (10a, b, c, d). A plurality of input contone and line work objects are received (100) containing contone or line work data for at least one pixel on a sheet. For each input contone object, at least one output contone object is generated (108) including colour data for each pixel in the input contone object. For each input line work object, at least one output line work object is generated (108) including colour data for each pixel in the input print data object. Control data is generated for each pixel indicating whether to select data from the output line work object or output contone object for the pixel, wherein the control data is used by logic to select colour 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.
