FO - Adding Filler Pages for page count multiple of 16
Hi,
I'm new to FO. I'm developing a FO document to
generate a catalog which has multiple sections. I have
a constraint on the length of each of these sections.
It has to be a multiple of 16 pages. If the data for a
particular section is less than a multiple of 16 pages
then the extra pages need to be blank pages or notes
pages with rules. eg. a section is 14 pages of data
then it should be followed by 2 blank pages to make it
16 pages. another section is 25 pages of data then it
should be followed by 7 blank pages to make it 32
pages. This is almost like force-page-count=16*x.
First of all I would like to know if this is possible.
If so, I would appreciate any pointers to get it done.
Thank you.
Prakash

No, you don't need an additional tool, only some custom Java code and
probably an extension to your stylesheet.
Step 1:
Use the Driver.getResults() method to determine the number of pages
generated during the first, normal run. See here for more info:
http://xml.apache.org/fop/embedding.html#render-info
Step 2:
You run FOP again with the same input file but now you set a parameter
to your XSLT stylesheet which generates the necessary number of blank
pages with normal XSL-FO means (page-sequences or page breaks or
whatever).
So you simply run FOP twice with the same input file and the same
stylesheet. You only need to extend your stylesheet so it can produce an
number of empty pages as specified through an XSLT parameter.

Jeremias is right, you can't do want you what with XSL-FO.
An alternative solution would be to post process the generated PDF using
a tool like iText to insert the desired number of blank pages.

Jeremias,
When you said a two-pass approach, would that be both
through FO processor or would I have to do the second
run with some other tool? At the end of the first run
I would have a PDF. If I would be using FO Processor
for the second run then how would I go about doing the
second run? If not, what are some other tools which I
can use to do the second run?
Thank you.

I don't think such a thing is directly possible with XSL-FO. Your best
chance is probably to do a two-pass approach, noting the number of
generated pages in the first run and then injecting additional blank
pages in the second run.
