Fixed in r100, please svn update.

By the way, if you want to create a PDF which takes advantage of JBIG2 image
compression, I'd recommend creating a normal PDF anyhow (e.g. with sam2p), and
optimizing it with pdfsizeopt.py. pdfsizeopt.py autodetects that JBIG2 can be
applied, tries it, and if it saves space, it recompresses the image using JBIG2.

not I want to convert JBIG2 to PDF, just want to test your application, btw, I 
have
no need of pdfsizeopt at all, just find pdfsizeopt is a good solution, and have
interesting in it.
It is my hobby to study PDF, I am a .net developer, and manage a java team, and 
our
company focus on email marketing. all I need to do at office has no business 
with
PDF, but I like PDF.
