       jbig2dec - File format converter specialized in JBIG2 decoding


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


       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 organzation, 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


       The options are as follows:

       -o file
              Store the decoded output in file.  Defaults to the input with  a
              different extension.  Set to - for standard output.

       -t type
              Force  a  particular  output  file format. Supported are png and

       -d or --dump
              Print the structure of the JBIG2  file  rather  than  explicitly
              decoding it.

       --hash Print a hash of the decoded document.

       -q or --quiet
              Suppress warnings and other diagnostic output.

       -v or --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.

              Show program version information.

       -h or --help
              Show usage summary.
