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 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 parser.

OPTIONS
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 pbm.

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

--hash
    Print a hash of the decode document.

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

-v or --verbose
    Report additional information about the decoding process.

--version
    Show program version information.

-h or --help
    Show usage summary.
