NAME

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       -e, --embedded
31              Expect embedded bit stream without file header.
32
33       -o file, --output file
34              Store the decoded output in file.  Defaults to the input with  a
35              different extension.  Set to - for standard output.
36
37       -t type, --format type
38              Force  a  particular  output  file format. Supported are png and
39              pbm.
40
41       -d, --dump
42              Print the structure of the JBIG2  file  rather  than  explicitly
43              decoding it.
44
45       -m, --hash
46              Print a hash of the decoded document.
47
48       -q, --quiet
49              Suppress warnings and other diagnostic output.
50
51       -v, --verbose
52              Report  additional information about the decoding process.  Pass
53              just -v for information about the file as  it's  being  decoded.
54              This is the same as --verbose=2.  Pass --verbose=3 or higher for
55              debugging information.
56
57       -V, --version
58              Show program version information.
59
60       -h, --help
61              Show usage summary.
