.TH jbig2dec 1 "2020 March 11" "Version 0.19" "jbig2dec Manual" .SH NAME jbig2dec \- File format converter specialized in JBIG2 decoding .SH SYNOPSIS .B jbig2dec .RI [ options ] .I file.jbig2 .br .B jbig2dec .RI [ options ] .I global-stream page-stream .SH DESCRIPTION The .B jbig2dec command converts JBIG2 files to png or pbm files. When passed a single .I 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 .I global-stream argument to request the embedded parser. .SH OPTIONS The options are as follows: .TP .BR -e ", " --embedded Expect embedded bit stream without file header. .TP .BI -o " file" ", --output" " file" Store the decoded output in .IR file . Defaults to the input with a different extension. Set to \fI-\fR for standard output. .TP .BI -t " type" ", --format" " type" Force a particular output file format. Supported are \fIpng\fR and \fIpbm\fR. .TP .BR -d ", " --dump Print the structure of the JBIG2 file rather than explicitly decoding it. .TP .BR -m ", " --hash Print a hash of the decoded document. .TP .BR -q ", " --quiet Suppress warnings and other diagnostic output. .TP .BR -v ", " --verbose Report additional information about the decoding process. Pass just \fB-v\fR for information about the file as it's being decoded. This is the same as \fB--verbose=2\fR. Pass \fB--verbose=3\fR or higher for debugging information. .TP .BR -V ", " --version Show program version information. .TP .BR -h ", " --help Show usage summary. .SH REPORTING BUGS Report bugs at https://bugs.ghostscript.com Contact the developers at the IRC channel #ghostscript at freenode.net or via the mailing list <gs-devel@ghostscript.com>. .SH AUTHOR This manpage was initially written by Sebastian Rasmussen <sebras@gmail.com> for jbig2dec and the Debian Project.
