Claim One:
1. A method for scaling a raster image, wherein the method comprises: obtaining a plurality of input scan lines having bits that represent pixels of the raster image; obtaining a first scaling value and a second scaling value; processing input scan lines by removing or duplicating selected pixels of individual input scan lines to create altered scan lines having a modified length, wherein the number of removed or duplicated selected pixels in each scan line is based in part on the first scaling value; generating a plurality of masks, wherein each mask comprises a plurality of bits and at least one selected bit, wherein the number of selected bits in an initial mask is determined by the second scaling value, wherein individual masks subsequent to the initial mask comprise an increasing number of selected bits; processing the altered scan lines with the plurality of masks to generate a plurality of output scan lines, wherein individual masks are used to combine the pixels of two adjacent altered scan lines to produce an individual output scan line, wherein the number of selected bits in each mask determine the ratio of pixels used from each of the adjacent altered scan lines, wherein the output scan lines are configured to form an image of a modified scale that utilizes a different number of scan lines than the image of the input scan lines; and communicating at least one output scan line with a device.
