After reading the Sept 2003 thread about Memory Performance, leaks (and
how wonderful ADA is), I modified my test program that generates
3 PDF files. The program now sleeps 30 seconds, calls Driver.reset(),
nulls the reference and sleeps again. In JMP this plots a square wave
between that you can
Hello,I'm using FOP (0.20.5) for several month. It's a nice tool
to generatedynamic pdf-documents in a web-environment (tomcat 4, java
1.4.1).Now I want to integrate charts which I generate in a servlet
powered by theJFreeChart-classes (an open source project). The response of
the servlet
I am having a problem when trying to use attribute sets, and I am unsure
on whether this is a problem with FOP or my newbie implementation of the
syntax (the most likely possibility)
I have the following attribute-set within my document which reads in
values from an XML file :
xsl:attribute-set

I don't know if the XSL-FO color space support supports CMYK or not.
Others may comment on this who have read the spec more than I.

Ben,
The President of my employer is a lawyer. Dunno if open-source will
happen anytime soon for that lib. ;-)
Have you checked if the open-source Multivalent lib supports this type
of operation? I'll try and take a gander too, but you should check
and see.
I will check it next week.
Well, in FOP 0.20.5 it is possible to generate uncompressed PDF documents.
Although this may increase the file size, sometimes dramatically, it makes
the RGB-CMYK replace operation much simpler,
Because the PDF document wont need to be decompressed before performing
those tasks.
Then, what you
Then, what you will need is a regular expression, that finds any 'RG' or
'rg' color commands, to replace them with 'K' or 'k', respectively.
Of course, the expression needs to be smart enough only to replace
occurrences of 'RG' or 'rg' that is actually color commands.
Searching for occurrences of

Ok, i understood that. But i think the color values must be changed too
or i'm wrong. I think there must be a conversion from rgb to cmyk values?!?
Right. I haven't created code that performs intelligent RGB - CMYK
conversion; rather, I replace specific RGB values with

Another attempt at guessing what your problem might be:
use text-align-last=justify, see also:

XSLFO only supports sRGB (gamma corrected!) and ICC colors. Of course,
the spec doesn'n mention how the colors in the output should look like.

Check whether iText or any other of the handful of PDF libraries
on sourceforge can help you with this problem.
