Re: Empty pdf more than 100k?
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?
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.

Re: Empty pdf more than 100k?
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.

Re: Empty pdf more than 100k?
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!
