Abstract
A method of modifying a digital representation of an image in which digital data defines the content of pixels of the image. The method comprises a) determining whether a predetermined degree of compression can be achieved if data defining a block of pixels is compressed by applying a predetermined compression algorithm; and, if not, b) discarding a portion of the data in the block, and repeating steps a and b on the most recently modified block until the predetermined degree of compression is achieved, and generating a compressed version of the image.
