1. An image encoder engine for encoding an image, comprising:

  • an image decomposer for decomposing the image into a header and at least one image block, each image block having a set of image elements and each image element having an original image data value;

    at least one block encoder for receiving each image block and for compressing each image block into an encoded image block by associating each original image data value of the image element with an index to a derived image data value in a set of quantized image date values; and

    an encoded image composer coupled to the block encoder for ordering the encoded image blocks into a data file.
