1. A method of processing image data defining a multiplicity of pixels which together form an image, the method comprising the steps of:

  • selecting data defining a brush profile;

    employing operator means to define a destination position in the image and to define a source position in the image different than the destination position such that there is a predetermined displacement relationship between the destination position and the source position, and repeating a cycle of;

    delineating a destination patch corresponding to a first region of the image including the destination position, the destination patch comprising an array of pixels each having an associated image data value,delineating a source patch corresponding to a second region of the image including the source position, the second region being different than the first region and comprising an array of pixels each having an associated image data value; and

    modifying the image data value of each pixel of the destination patch in dependence upon the image data value of both said destination patch pixel and the corresponding source patch pixel and in dependence upon the brush profile data,the destination and source patches of each cycle differing in position from the destination and source patches of the preceding cycle.
