PdfTokenParseError when trying to optimize pdf #39

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
The PDF is the book "Analytic Combinatorics", available from 
http://algo.inria.fr/flajolet/Publications/books.html

I used "./pdfsizeopt.py --use-pngout=true --use-jbig2=true 
--use-multivalent=true --do-unify-fonts=false" to optimize.

What does pdfsizeopt display when running the command above?

I get:

...and no output pdf is produced.

I checked out the sources, and my copy of pdfsizeopt is identical to the 
current checkout: $Id: pdfsizeopt.py 134 2009-11-29 11:48:12Z ptspts $

Sorry for the long time it took for me to respond.

Thank you for reporting this bug. It's fixed in r143.

Please note that book.pdf is invalid: its xref table contains the offset 688, 
but there is no valid object there. I made pdfsizeopt.py ignore such a problem 
(printing a warning instead).
