It compresses 1bpp (black and white) images only. +.sp +jbig2enc is a library that encodes JBIG2 images. +.sp +\fBjbig2\fP is a command\-line tool that uses the jbig2enc library to convert an +image to the JBIG2 format. \fIimagefile\fP can be in any format readable by +leptonica (png, jpeg, tiff, gif, webp, jp2, bmp, pnm, spix). The image +is converted to 1bbp (monochrome) before processing. +.sp +Without the \fI\-p\fP, \fI\-\-pdf\fP option, the converted image is written to +standard output. This should be redirected to a file, normally with +the \fI\&.jb2\fP extension. If stdout isn\(aqt redirected to a file (or a pipe), +the JBIG2 data will be written to the terminal, which may get confused. +.sp +There is no way to have \fBjbig2\fP read an image file on standard input. This +is by design, as it needs to seek within the file. +.sp +All options must appear before the filename. With the generic encoder +(no \fI\-s\fP option), anything after the filename is silently ignored. The +symbol encoder (\fI\-s\fP) can handle multiple images (which end up as pages +in the JBIG2 file). +.sp +The \fI\-r\fP, \fI\-\-refine\fP option mentioned in the documentation and in +the \fI\-\-help\fP output of \fBjbig2\fP is \fIdisabled\fP in this version of +\fBjbig2\fP\&. +.SH OPTIONS +.\" some of these are from the HTML file, some from --help. +. +.INDENT 0.0 +.TP +.B \-b \fIbasename\fP +Output file root name when using symbol coding in PDF mode (\fI\-s\fP +and \fI\-p\fP).

This drastically reduces the encoding time (by a factor +of about 2 on some images) although it doesn\(aqt typically save any +bytes. This is an option because some versions of jbig2dec (an open +source decoding library) cannot handle this. +.TP +.B \-p\fP,\fB \-\-pdf +The PDF spec includes support for JBIG2 (Syntax\->Filters\->JBIG2Decode in +the PDF references for versions 1.4 and above). However, PDF requires +a slightly different format for JBIG2 streams: no file/page headers or +trailers and all pages are numbered 1. In symbol mode the output is to +a series of files: symboltable and page\-n (numbered from 0). By default +these are named \fBoutput.sym\fP and \fBoutput.0000\fP, \fBoutput.0001\fP, +etc. Use \fI\-b\fP to change the base filename. +.TP +.B \-s\fP,\fB \-\-symbol\-mode +Use symbol encoding.
