15 The jbig2dec command converts JBIG2 files to png or pbm files.
16
17 When passed a single file argument it is interpreted as a JBIG2 file
18 stream, with either sequential or random-access organization.
19
20 When passed two stream arguments, they are interpreted as the global
21 and page-specific portions of an embedded organization, as used in PDF.
22 If a particular page references no global segment stream, /dev/null can
23 be passed for the global-stream argument to request the embedded
24 parser.

28 The options are as follows:
29
30 -o file
31 Store the decoded output in file. Defaults to the input with a
32 different extension. Set to - for standard output.
33
34 -t type
35 Force a particular output file format. Supported are png and
36 pbm.
37
38 -d or --dump
39 Print the structure of the JBIG2 file rather than explicitly
40 decoding it.
41
42 --hash Print a hash of the decoded document.
43
44 -q or --quiet
45 Suppress warnings and other diagnostic output.
46
47 -v or --verbose
48 Report additional information about the decoding process. Pass
49 just -v for information about the file as it's being decoded.
50 This is the same as --verbose=2. Pass --verbose=3 or higher for
51 debugging information.
52
53 --version
54 Show program version information.
55
56 -h or --help
57 Show usage summary.
