Abstract
An input image is comprised of an array of pixels in rows and columns having P.sub.R pixels-per-row and P.sub.C pixels-per-column. To generate a scaled replica of the input image, the number of pixels-per-row P.sub.R ' and the number of pixels-per-column P.sub.C ' that are to be in the scaled replica are selected, where P.sub.R ' and P.sub.C ' are positive integers which can be larger or smaller than P.sub.R and P.sub.C. Then the input image is distorted such that the spacing between columns is (P.sub.R '-1)x and the spacing between rows is (P.sub.C '-1)y, where x and y are arbitrary units of distance, such as one inch or one meter. Then the distorted input image is overlaid with a new row-column array, where the spacing between columns is (P.sub.R -1)x and the spacing between rows is (P.sub.C -1)y, and where x and y are the same units of distance that are in the distorted input image. Then, using the above described spacings between the rows and the columns in the distorted input image and the overlaid new array, the pixels for the scaled replica are generated as a function of the various areas which those rows and columns delineate.
