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 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.
