Web1 Answer. You can't represent such a transform by a 2 × 2 matrix, since such a matrix represents a linear mapping of the two-dimensional plane (or an affine mapping of the one-dimensional line), and will thus always map ( 0, 0) to ( 0, 0). So you'll need to use a 3 × 3 matrix, since you need to represent affine mappings.
