A method and apparatus are disclosed which permit a seamless halftoning of an image by halftoning regions of the image independently and/or in parallel. Each region of the image being arbitrarily determined, and being halftoned on the basis of halftoned pixel results of pixels within a predetermined neighborhood of the region. The arrangement providing a greater flexibility in the independent halftoning of the regions, while providing substantially seamless joins between abutting halftoned regions of the image. Further, the arrangement also provides a mechanism for parallel processing (halftoning) of abutting regions of an image with substantially seamless results.
