How do you convert from CCITT Group 4 to JBIG/JBIG2?

Question

Would it be possible for someone to point me to the general direction on how to convert from CCITT Group4 to JBIG and/or JBIG2 compression? This would be for either single page and multi page tiffs.

Answer 1

After further research into the source code it is not possible with libtiff.net as the compression type JBIG is only a placeholder in the library and the codec is not actually implemented. For those looking for an answer to this I ended up using the Jbig2Enc from the following links...
