Dear Peter, Using revision 224 of pdfsizeopt with the document at http://www.sp4comm.org/docs/sp4comm.pdf I am getting the following output: ---- info: This is pdfsizeopt.py rUNKNOWN size=318356. info: using Java for Multivalent: /usr/bin/java info: loading PDF from: sp4comm.pdf info: loaded PDF of 4175835 bytes info: using Ghostscript gs: GPL Ghostscript 9.05 (2012-02-08) info: decompressing 72 bytes with Ghostscript /Filter/FlateDecode/DecodeParms <</Columns 5/Predictor 12>> info: decompressing 2211 bytes with Ghostscript /Filter/FlateDecode/DecodeParms <</Columns 5/Predictor 12>> info: found 1914 obj offsets and 39 obj streams in xref stream Traceback (most recent call last): File "/tmp/pdfsizeopt/trunk/pdfsizeopt.py", line 7887, in <module> main(sys.argv) File "/tmp/pdfsizeopt/trunk/pdfsizeopt.py", line 7849, in main ).Load(file_name) File "/tmp/pdfsizeopt/trunk/pdfsizeopt.py", line 3504, in Load data, do_ignore_generation_numbers=self.do_ignore_generation_numbers) File "/tmp/pdfsizeopt/trunk/pdfsizeopt.py", line 3859, in ParseUsingXref xref_ofs, xref_obj_num, xref_generation) File "/tmp/pdfsizeopt/trunk/pdfsizeopt.py", line 3790, in ParseUsingXrefStream obj_num) File "/tmp/pdfsizeopt/trunk/pdfsizeopt.py", line 2834, in ParseObjStm objstm_data = self.GetUncompressedStream() File "/tmp/pdfsizeopt/trunk/pdfsizeopt.py", line 2327, in GetUncompressedStream return PermissiveZlibDecompress(self.stream) File "/tmp/pdfsizeopt/trunk/pdfsizeopt.py", line 229, in PermissiveZlibDecompress uncompressed = zlib.decompressobj().decompress(data) zlib.error: Error -3 while decompressing: incorrect header check ---- As the document may change/be updated, the md5sum of the copy that I have here is f22d1e72e38601a4b32861c653e2b24d. I don't know if I am allowed to post the file here, but can gladly post it if you ask me. I suspect that the problem with the decompression *may* be related to the fact that the document is (apparently) encrypted, as the output of pdfinfo is: ---- pdfinfo sp4comm.pdf Title: livre.dvi Creator: dvips(k) 5.94b Copyright 2004 Radical Eye Software Producer: Acrobat Distiller 8.1.0 (Macintosh) CreationDate: Tue Apr 29 17:05:46 2008 ModDate: Sun Nov 22 17:43:59 2009 Tagged: no Pages: 388 Encrypted: yes (print:yes copy:no change:no addNotes:no) Page size: 453.543 x 680.315 pts File size: 4175835 bytes Optimized: yes PDF version: 1.6 ---- Is that the case? If you need any further information, please let me know. Thanks, Rogério Brito. P.S.: As a last resort, of course, it is way too easy to circumvent such things with, for example, a pass of ghostscript (e.g., ps2pdf), but it would be nice to have pdfsizeopt warn the user of this potential (say, perhaps, with a message suggesting the possibility above) instead of dumping the stack trace.

Great, much more informative, and separating the code in the extra class makes the code a bit easier to read. Thanks. |
