Abstract

A system and process for generating and using mixed raster content files is described. MRC files may be created directly from an application, rather than being processed from a composite image, to separate a single image into background, foreground, and selection masks for each page. Also, an improved MRC structure is described in which only relevant portions are contained in background, foreground, and selection layers for each page.
