Abstract
A method and apparatus enables derivation of a bitmap representation of an image, where the image includes a region filled with a pattern. The method includes the steps of: accessing an original pattern bitmap segment from within the image; translating a copy of the original pattern bitmap segment to the origin of the bitmap representation of the image as a reference pattern bitmap and arranging it as a reference pattern bitmap with a pattern that evidences a consistent phase regularity with the original pattern bitmap segment; filling the region to be filled with the pattern by determining a correspondence of an anchor pixel of the region to a pixel in the reference pattern bitmap; ascribing an attribute of the corresponding pixel in the reference pattern bitmap to the anchor pixel of the region; and repetitively determining correspondence of each further pixel in the region to a further pixel in the reference pattern bitmap and ascribing an attribute of each further pixel of the reference pattern bitmap to each further pixel in the region, until all pixels in the region have been processed.
