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: -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 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. --version Show program version information. -h or --help Show usage summary.
