.TH jbig2dec 1 "2020 March 11" "Version 0.19" "jbig2dec Manual" .SH NAMEjbig2dec \- 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 DESCRIPTIONThe.B jbig2deccommand converts JBIG2 files to png or pbm files. When passed a single.I fileargument it is interpreted as a JBIG2 file stream, with eithersequential or random-access organization. When passed two stream arguments, they are interpreted as theglobal and page-specific portions of an embedded organization,as used in PDF. If a particular page references no globalsegment stream, /dev/null can be passed for the.I global-streamargument to request the embedded parser. .SH OPTIONSThe options are as follows:.TP.BR -e ", " --embeddedExpect 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 ", " --dumpPrint the structure of the JBIG2 file rather than explicitly decoding it..TP.BR -m ", " --hashPrint a hash of the decoded document..TP.BR -q ", " --quietSuppress warnings and other diagnostic output..TP.BR -v ", " --verboseReport 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 ", " --versionShow program version information..TP.BR -h ", " --helpShow usage summary. .SH REPORTING BUGSReport bugs at https://bugs.ghostscript.com Contact the developers at the IRC channel #ghostscript at freenode.netor via the mailing list <gs-devel@ghostscript.com>. .SH AUTHORThis manpage was initially written by Sebastian Rasmussen<sebras@gmail.com> for jbig2dec and the Debian Project.
