Package: jpeginfo Version: 1.6.0-6 Please note that the documentation is not accurate, since jpeginfo is bound to the JPEG codestream the underlying libjpeg can actually decode [*]
It should indicate that this is a limited implementation of ITU 81 (only huffman and sequential lossy 8bits is supported).
