Abstract
An image processor realizes a gradation function and prints and records color information sent from a host computer, as a high-definition and multi-halftone level image. The processor fetches PDL data into an input buffer by interrupt processing, and interprets an input PDL command in accordance with language specifications. If the input data is a drawing command, the input data is converted into a page object format supported by a hardware renderer. Subsequently, as pre-processing for rendering the page object, a determination is made if banding rendering (banding) processing is possible.
