Abstract
A method of generating a composite image on a record medium at a first resolution resulting from two subsidiary images defined by pixels at a second resolution lower than the first. The method comprises generating an array of control data at the second resolution, the control data indicating the relative locations of the subsidiary images in the composite image at the first and second resolutions, generating data defining the composite image at the second resolution under the control of the control data, interpolating the second resolution composite image up to the first resolution, the relative locations of the subsidiary images at the first resolution being determined in accordance with the control data, and causing the first resolution composite image to be recorded on the record medium.
