  JBIG2 is a Turing-complete (in some circumstances) file format used in fax machines, PDFs and JPEG 2000. It aggressively deduplicates the image and in order to enable lossless compression stores additional info in a form of blocks to be apllied to inputs and outputs via various bitwise operators.
