SYNOPSIS

10       jbig2dec [options] file.jbig2
11       jbig2dec [options] global-stream page-stream

DESCRIPTION

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.

OPTIONS

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.
