Re: Empty pdf more than 100k?
Hello,
I have the same problem migrating from fop 0.20 to 0.94 - a file generated
using fop 0.20 = 147K, whilst the same file generated using fop 0.94 =
434K. Also, I'm using jdk1.5
Because these pdf files are dowloaded from a web app, the increase in file
size will mean the powers that be deciding that we do not migrate to 0.94 at
all.
Any other suggestions/observations since the last posts??
Thanks,
Paul

Not sure whether this is applicable or not, but I have used Multivalent
(http://multivalent.sourceforge.net/) in the past for re-ordering pages
(from one-up to two-up etc) and often was surprised at the output being
increasingly smaller, without loss of quality. Often I used it to assess
whether a certain PDF could be made smaller at all and when the change
was significant, I sometimes added it to the process.
You can use Multivalent just for decreasing / compacting file size of
PDF. Test it to see if it works for you. The outcome may be of help for
the programmers too, to know whether it is possible at all and to what
level to decrease the size.

I haven't done any experiments to prove it, but I suspect it has to do
with the table border painting. We've improved table border quality a
lot in 0.94 which causes increased size of the page content. If I take
one of the pages in between which have a large table the page content
size is three times as big in 0.94 as in 0.20.5:
page 13: 0.20.5: 5515 bytes, 0.94: 17012 bytes
I'm surprised at the amount of the increase. But I'm afraid I cannot do
anything about that for the moment.

That's not the same problem. The increase is not ~105KB but almost 300KB.
Something else must be wrong. If it were about the color profile, it
would be an increase of about 105KB. If you post the two PDFs (before
and after) I can better tell what exactly could be going on.
