Abstract
A method for producing a scaled output image by manipulating image data from an input image is disclosed. The scaled output image can have non-uniformly scaled regions and a uniformly scaled region. The method includes an operation that defines pixel locations within the uniformly scaled region of the output image based on uniformly scaling a portion of the input image. There is also an operation that determines a non-uniform scale factor. The non-uniform scale factor is used to define a gap between pixel locations within the non-uniformly scaled regions. Another operation determines error correction values within the non-uniformly scaled regions. The method can also include an operation that defines pixel locations for the non-uniformly scaled region of the output image based on increments of the non-uniform scale factor and error correction values.
