Abstract:

A method and system for generating designs by repetition of a user-defined image component which is arranged throughout an image pixelmap according to any desired pattern. Vector descriptions are used to specify pixelmap locations where the unit cell is to be copied. A user can define placement vectors that copy the unit cells apart from one another, adjacent one another or in an overlapping pattern. In the latter case, a formalism is provided for "masking out" a portion of the unit cell to avoid deletion of desired image information.
