DNG recompression by unpacking Lossless JPEG 1992 #45
Description
DNG compresses either lossy (JPEG DCT) or lossless; the lossless compression is done by
LJ92 (Lossless JPEG 1992, DPCM+Huffman) which was developed 24 years ago.
Recompressing this could give the opportunity to use modern compression algorithms.
