Abstract
A raster image processor for an all points addressable marking engine includes a page memory having a data input and a write enable input. Halftone tints are applied to bit maps of objects stored in the page memory by applying a tint bit pattern to the data input of the page memory while a bit pattern representing the object is being applied to the write enable input of the page memory. Prior to applying the object bit maps to the write enable input of the page memory, the object bit maps may be combined with a texture bit pattern or clipped by a window bit pattern.
