Hi all,
I am a newer, and when I try to use publican to generate a huge pdf
document, I got the following exception:
......

I have already try to add the jvm options in the ~/.foprc file
this is my .foprc file:
FOP_OPTS='-Xms200m -Xmx1024m -XX:-UseGCOverheadLimit'
You might want to track down how to set in the Java environment outside
of FOP.
On RHEL /etc/java/java.conf looks to be the file.
But I still get this exception. And I wander what is the "Line 1 of a
paragraph overflows the available area by 25000mpt" means?
This is unrelated to your issue. it's FOP saying it couldn't fit the
content inside the box constraints and wrote out side the box by a tiny
bit. I think it's due to the way FOP does nested elements.
By the way, is it possible for publican to start from the chapter 3
rather than chapter 1?
No. It would be very difficult to get this to work at the publican level
since you'd have to prevent people linking across different "chunks".
It'd be best to handle it at the renderer level, FOP, but it can't do
that AIUI.
If you are using publican >= 2.8 you could try installing wkhtmltopdf,
it might handle the larger book size better. Once it's installed
publican will detect it and use that instead of FOP.
Because if I can not generate so big pdf file, I may try to generate
several small pdf files, and I don't want all these small pdf files
start from chapter 1.
Cheers, Jeff.
