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 dif-
	    ferent 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 decod-
	    ing 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.
