An image format for storing digital images within a baseline DCT
compatible bitstream comprises entropy coded image data, a first
application marker storing a first data value using a first encoding
method to convey a first information value related to the image, and a
second application marker storing a second data value using a second
encoding method to convey the same said first information value related
to the image. More specifically, the first application marker uses TIFF
tags within an Exif application marker and the second application marker
uses a FlashPix compatible structured storage stream, while the entropy
coded data includes restart markers to define tile boundaries within the
entropy coded image data.
