Abstract
Methods and systems for transcoding continuous tone Run Length Limited (RLL) encoded datastreams for including information for identifying halftone screens within the datastream are disclosed. Sequential packets comprising headers and bitmap data are identified within the datastream. Halftone screens associated with bitmap data within the packets are identified and merged into the packets to generate a modified RLL output.
