Abstract:
1. A method for calculating data for pixels of a destination image from data for pixels of a source image, the pixels of the source and destination images arranged in rows and columns along a first axis and a second axis, respectively, the method comprising: calculating a first set of data corresponding to pixels scaled along the first axis for a first portion of pixels of the destination image from the data for a plurality of pixels along the first axis for a first portion of pixels of the source image, the first portion of pixels of the source image arranged in spans and columns of pixels, the span of pixels less than the length of one row of pixels of the source image; calculating data corresponding to pixels scaled along the second axis for the first portion of pixels of the destination image from the first set of data; calculating a second set of data corresponding to pixels scaled along the first axis for a second portion of pixels of the destination image from the data for a plurality of pixels along the first axis for a second portion of pixels of the source image; calculating data corresponding to pixels scaled along the second axis for the second portion of pixels of the destination image from the second set of data; and including the data for the pixels scaled along the first and second axes for the first and second portions of pixels of the destination image as part of the data for the pixels of a final destination image.
