Image content may be generated in high resolution by performing raster operations, and half-toning is then performed on the image content. Due to such a sequence, a substantially consistent image may be generated on different printers irrespective of the degree of half-toning. Another aspect of the present invention enables the computation requirements to be reduced by storing in a temporary buffer the image data (paint, destination, source) used multiple times.

1. Field of the Invention
The present invention relates to printers, and more specifically to a rasterizing sub-system used in a printer.
2. Related Art
The present invention will be described with reference to the accompanying drawings, wherein:

FIG. 2 is a flow chart illustrating a method in accordance with an aspect of the present invention;
1. Overview and Discussion of the Invention
According to an aspect of the present invention, half toning is performed on the image after the raster operations are applied. Raster operations may be performed on a source image, a destination image and a paint to obtain a final image. By performing the half-toning operation on the final image (generated by the raster operations), the content of a printed image may be substantially the same irrespective of the degree of half-toning.
According to another aspect of the present invention, image data used many times for performing raster operations, is stored in a temporary buffer such that the data need not be regenerated. As a result, the image may be generated while minimizing the processing requirements and/or memory access requirements.
