Some time ago I had a need to parse the contents of compressed streams
of pdfs, I wrote some hacky code to do it:

It's perl code, its just using Compress::Zlib to pull out the bits I
need.  Anyway it suggested to me that there'd be other, better tools
out there for decompressing pdfs... and there is:

pdftk mydoc.pdf output mydoc.clear.pdf uncompress

pdftk is available as a Debian package. Might be an alternative to
adding debug code?
