摘要： A method of modifying a digital representation of an image in which digital data defines the content of pixels of the image. The method comprisesa) 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, andrepeating 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.
