DNG recompression by unpacking Lossless JPEG 1992

Open StephanBusch opened this issue 9 years ago • 0 comments

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.
