seems to work fine pdf format strips the header and the tail of the jbig2 file as specified in PDF, Version 1.7 (ISO 32000-1:2008) section 7.4.7 JBIG2Decode Filter
Further, some pdf files contain jbig2 streams with last segment of unspecified size (ff ff ff ff). libjbig2dec can not handle this.

I wish this helpful for you As far as I can tell there's not a lot of options for encoding JBig2 and no native free ones.
Windows Imaging SDK ($2500+) JBIG2 Compression Codec SDK for .NET ($1,800) jbig2enc (free but c code only)

should help you out There's no current way to have Ghostscript pass JBIG2 images unchanged.
The pdfwrite device doesn't permit JBIG2Encode as a possible encoding method so you can't use that.
