NAME
jbig2dec - File format converter specialized in JBIG2 decoding
SYNOPSIS
jbig2dec [options] file.jbig2
jbig2dec [options] global‐stream page‐stream
DESCRIPTION
The jbig2dec command converts JBIG2 files to png or pbm files.
When passed a single file argument it is interpreted as a JBIG2 file
stream, with either sequential or random‐access organization.
When passed two stream arguments, they are interpreted as the global and
page‐specific portions of an embedded organization, as used in PDF. If a
particular page references no global segment stream, /dev/null can be
passed for the global‐stream argument to request the embedded parser.
OPTIONS
The options are as follows:
‐e, ‐‐embedded
Expect embedded bit stream without file header.
‐o file, ‐‐output file
Store the decoded output in file. Defaults to the input with a
different extension. Set to ‐ for standard output.
‐t type, ‐‐format type
Force a particular output file format. Supported are png and pbm.
‐d, ‐‐dump
Print the structure of the JBIG2 file rather than explicitly de‐
coding it.
‐m, ‐‐hash
Print a hash of the decoded document.
‐q, ‐‐quiet
Suppress warnings and other diagnostic output.
‐v, ‐‐verbose
Report additional information about the decoding process. Pass
just ‐v for information about the file as it’s being decoded.
This is the same as ‐‐verbose=2. Pass ‐‐verbose=3 or higher for
debugging information.
‐V, ‐‐version
Show program version information.
‐h, ‐‐help
Show usage summary.
