Abstract
Methods and systems herein provide for halftoning of Run length (RL) encoded datastreams. In one embodiment, a print controller identifies a packet within a RL encoded datastream. The packing includes a header and a block of continuous tone data. The print controller identifies an array of conversion values for converting RL encoded data to halftone data, and indexes the array using one or more bytes of the block of bitmap data. The print controller then outputs halftone data from the conversion array based on the index to convert the RL encoded continuous tone data of the packet to halftone data for a print engine.
