If I opt the pdf create by pdftk

pdftk Seven.Steps.To.A.Successfull.Business.Plan.pdf output aa.pdf

and 

python pdfsizeopt.py aa.pdf
I got the following error,

image
only pdf, no problem)

And what does sam2p_np mean?

Please open separate issues for each different topic. In this issue I'll 
respond only
to ``NotImplementedError: generational refs not implemented''

sam2p_np means sam2p.exe with ZIP compression, without predictor.

I'm quite surprised that pdfsizeopt.py works on Windows. Which Python 
distribution
and version are you using? Could you please attach the jbig2.exe you have 
compiled?

I tried python 2.5 (directly download from python.org),of course I modified some
content of pdfsizeopt.py, I will paste the modification when I am back home.
and will attach jbig2.exe when I am back home.

you can download jbig2.exe here,
http://soft.rubypdf.com/softwares/windows-version-jbig2-encoder-jbig2-exe
and the modification of pdfsizeopt.py I did,
line 66,
--return "'%s'" % string.replace("'", "'\\''")
++return "\"%s\"" % string.replace("'", "'\\''")
windows treats single quote as part of path, so have to use double quote.

line 5824
--ShellQuoteFileName(multivalent_jar)
++'Multivalent.jar'
the multivalent_jar variable does not get the correct path of Multivalent.jar, 
why
not directly use Multivalent.jar?

To get rid of the ``generation refs not implemented'' error, please sync to r96 
(svn
update), and try again.
