Empty pdf more than 100k?
Hello,
we were using fop 0.20 and decided to migrate to the latest fop 0.94.
Everything were fine except some code that needed to be adjusted.
After some tests, we discover that all generated pdf have a much bigger
size. From 6k with fop 0.20 it is now 112k?!
After some investigations it seems inside the pdf one object streamed is
much bigger but I have no idea what kind of element it could be (font, color
profile, ...)
Anybody knows what could be the origin of the problems? Generated Pdf works
fine but it's really a waste of space, especially when sending emails with
pdf attached).
Thanks for any help!
Laurent

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.

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

Hi,
Could the fonts be getting embedded in the pdf in .94?
I believe acrobat can tell you whether a font is embedded. (Other tools probably will also)

I was using jdk 1.2.4_13 and just installed jdk 1.2.4_16.
the previous example simple.fo is now 5014 bytes!
So it is definitely what you said earlier regarding the jvm version.
Is there a way to force the profile to be the small one? I can change my jvm
locally but I'm not sure I can do the same with our linux production servers
jvm...
Would there be any parameter to force it or disabling this color profile?
Anyway, thanks for this helping answer!
Best regards!

I take it you're using a Sun JVM prior to 1.4.2_16. There seems to be a
bug in earlier version where a Class.getResourceAsStream(String) returns
null if the filename contains a space character. I didn't notice this
problem before but I was able to reproduce it on Sun JDK 1.4.2_13. It
disappeared when I installed 1.4.2_16. It does not appear in 1.5.0_10
(or later) and 6.0_03.
Just to explain what this has to do with the PDF growing to over 100KB:
There's a fallback built in that loads the JDK's default sRGB color
profile if the one bundled with FOP cannot be loaded for some (ha!)
reason. The sRGB profile Sun bundles is about 100KB in size while ours
is only about 5KB.

I tried to check with acrobat reader and compare the properties, but didn't
see any differences.
I have attached a file containing the one generated pdf from the
examples\fo\basic\simple.pdf
What size do you have for the same example?
Anyway, thanks for your answers, coz I was getting mad yesterday...

Ok, I've added the necessary option to FOP Trunk:
http://svn.apache.org/viewvc?rev=619417&view=rev
See the XML files in the revision above for documentation.

So far we haven't included an option to skip the inclusion of the sRGB
profile. That's because XSL-FO defines all RGB colors to be in the sRGB
color space. If the color profile is not added, the colors are actually
wrong. If you really just use black, it's obviously unnecessary. But it's
not unproblematic to add this option since we have to take care that we
don't accidentally break support for PDF/A. PDF/A requires calibrated
colors. I'll see what I can do.

Re: Empty pdf more than 100k?
Posted by Oisín <Oi...@voila.fr>.
Hello!
after updating to 0.94 I also found an increase of PDF filesize from 3k to
10k. After turning off compression I found out that this is due to the
included color profile. As these files are simple invoices containing some
tables an text in black only, I would like to remove the color profile from
the generated PDFs. With some thousand of thes files generated the amount of
disk space needed adds up considerably.
Thus, how can I avoid the color profile to be included into the PDFs? I'm
using FOP embedded into a Java application but haven't found any hint in the
docs.
Thanks,
Oisín
That the PDFs are a little bigger is to be expected.
"Hello world" in FO:
FOP 0.20.5: 2KB
FOP 0.94: 5KB
The increase is due to:
- additional XMP metadata (~0.6KB)
- embedded sRGB profile to make sure that the color space is the same as
is defined by XSL-FO (0.20.5 wrongly used device-specific RGB). (~2.5KB)
As Jonathan mentioned, the size is likely to be because of embedded
fonts but I'm not sure not embedding the font is the right way. If you
send the PDF to me I can tell you what's in it (only if you want).

That the PDFs are a little bigger is to be expected.
"Hello world" in FO:
FOP 0.20.5: 2KB
FOP 0.94: 5KB
The increase is due to:
- additional XMP metadata (~0.6KB)
- embedded sRGB profile to make sure that the color space is the same as
is defined by XSL-FO (0.20.5 wrongly used device-specific RGB). (~2.5KB)
As Jonathan mentioned, the size is likely to be because of embedded
