Abstract
A method and apparatus for dithering vectors in which the dither matrix is aligned to the vector and not to the display coordinate space. The dither matrix is aligned to the vector according to the major axis of the vector. In a preferred embodiment the dither matrix is rectangular in shape to correspond to the shape of the vector. The vector aligned dither matrix ensures that the individual pixels which make up the vector are dithered with elements more likely to simulate the original intermediate intensities.
