Abstract
To reduce rendering time for an image to be generated, an image to be generated, such as a page of a document, is divided into non-overlapping regions. Within each region, a determination is made whether all of the data contained therein is achromatic. If so, achromatic data is rendered for a single component of a multi-component color space. Pixel values are stored in one section of a frame buffer that relates to the single component. The other components of the color space use multiple references to the pixel data stored in this one section, rather than being separately rendered.
