Conversions between spool files and a PDL within a pipeline of modular filters

摘要

Conversion of spool files to a PDL within a pipeline of modular filters. A spooler is adapted to receive content to be rendered on a destination device, and one or more filters are adapted to render the content on the destination device. In other embodiments, the filters are arranged in a pipeline configuration to execute a variety of functions in connection with rendering the content on the destination device. The filters can convert content in a spool file format into corresponding PDL representations, and vice versa.
