A first scanline of an input image is spatially transformed into a first pixel sequence of an output image. Holes in the first sequence are interpolated if magnifying the input image. Overlapping pixels in the first sequence are adjusted if minifying the input image. After transforming the first scanline, a second scanline of the source image is transformed into a second pixel sequence of the output image. Holes in the second sequence are interpolated if magnifying the input image. Overlapping pixels in the second sequence are adjusted if minifying the input image. Overlapping pixels across the first and second sequences are adjusted and holes between the first and second sequences are interpolated if rotating the input image.
