JPEG2000 Code Stream Image Format

Similar to JPEG-1, JPEG2000 defines both a file format and a code stream. Whereas the latter entirely describes the image samples, the former includes additional meta-information as the resolution of the image or the color space that has been used to encode the image. JPEG2000 images should be boxed in the JPEG2000 file format, where they get the .jp2 extender. The part-2 extension to JPEG2000, also enriches this file format by including mechanisms for animation or composition of several code streams into one single image. Images in this extended file-format use the .jpx extension.
