[reportlab-users] How to make smaller PDF?

This sounds strange.  Is compression on?  i.e. if you look in
the file, are any words in English or numbers from the source
document, or is each page a stream of unreadable 'goop' with
something about 'filters' and 'flate'?

If for some reason zlib is not importable on your system,
compression will turn itself off. =20

If you could cut out and upload one representative page somewhere
we could comment on this; it may be that you really do have a large
amount of information.  Each cell could be doing line dawing=20
instructions, setFont calls and other things; but 50kb of
compressed output for highy repetitive stuff suggests 500kb
uncompressed, which I find hard to believe.
