Abstract
A method of generating a graphics pattern comprising digital data defining the color content of pixels of the pattern within a pattern area at a first, high resolution, comprises defining (step 21) the color content of 'seed' pixels at selected positions within the pattern area which are to influence the resultant pattern. The remaining pixels at the first high resolution are considered as having undefined color content. Successively lower spatial resolution versions of the pattern area are generated in accordance with a predetermined algorithm which, when sufficient defined pixels exist in the next higher resolution version neighboring an undefined pixel, interpolates color data for the corresponding lower resolution pixel, until all pixels of a lower resolution version contain defined data (step 25). A version of the pattern area is generated at the first high resolution and the content of at least the previously undefined first high resolution pixels is obtained from the lower resolution versions of the pattern area.
