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.
