PDF 1.5 Cross Reference Streams

[GoogleCodeExporter]

Virtually all PDFs produced by recent versions of pdflatex can not be processed 
by pdfsizeopt on account of them containing cross reference streams.  This 
results in errors such as:

Traceback (most recent call last):
  File "pdfsizeopt.py", line 6186, in <module>
    main(sys.argv)
  File "pdfsizeopt.py", line 6162, in main
    ).Load(file_name)
  File "pdfsizeopt.py", line 2991, in Load
    data, do_ignore_generation_numbers=self.do_ignore_generation_numbers)
  File "pdfsizeopt.py", line 3076, in ParseUsingXref
    'PDF-1.5 cross reference streams not implemented')
NotImplementedError: PDF-1.5 cross reference streams not implemented

Given that pdflatex is starting to use these by default (unless 
\pdfminorversion=4 or below) it would be nice to see them supported.

Please attach a small sample PDF which pdfsizeopt cannot load.

Thank you for adding this feature request and for the example PDF.

PDF 1.5 cross-reference stream (xref stream) and object stream parsing support 
has been added in r162. Please svn update, try it with your PDFs and report any 
problems in this issue.

Thank you very much for

1. this great script !!!

texlive!
