Hi,
Check the FAQ for hints and caveats:
http://xml.apache.org/fop/faq.html#faq-N10597
public static void main(String args[]) {
try {
Driver driver=new Driver();
driver.setOutputStream(new FileOutputStream(args[2]));
driver.setRenderer(Driver.RENDER_PDF);
Transformer transformer=TransformerFactory.newInstance()
.newTransformer(new StreamSource(new File(args[1])));
transformer.setParameter("page-count","#");
transformer.transform(new StreamSource(new File(args[0])),
new SAXResult(driver.getContentHandler()));
here i get a nullpointer, because first you must call driver.run.
String pageCount=Integer.toString(driver.getResults().getPageCount());
driver=new Driver();
driver.setOutputStream(new FileOutputStream(args[2]));
driver.setRenderer(Driver.RENDER_PDF);
transformer=TransformerFactory.newInstance()
.newTransformer(new StreamSource(new File(args[1])));
transformer.setParameter("page-count",pageCount);
transformer.transform(new StreamSource(new File(args[0])),
new SAXResult(driver.getContentHandler()));
}
catch( Exception e) {
e.printStackTrace();
}
}
}
but thats not what i want.
I'm looking for an solution to calculate the number of pages without the
complete rendering process.
The FOP library provides a method to get the total page count after a FO
document has been rendered. You can implement your own wrapper to do a dummy
rendering, inquire the total page count and the perform the real rendering
an own wrapper? why doesnt exists a default-wrapper? How could i implemet
this?
thanks alex
