Hi,
I'm using FOP atm to create PDF previews for a client of my company. The PDF previews are based on a template with for example a header and a footer and a certain markup for the text.
Now I encounter a problem that I'm not able to explain. I have a header image which has a fixed height and width (defined in the XSL file). But this image is not displayed correctly if my page height is below a certain value. The page height is given in the XML input, since the template does not know how large it is going to be.
With excactly the same input, besides page-height, the image differs in size (it's being scaled).
I've put a border around the block where the image is put in. This border also increases in height when the image height increases.
With FOP 0.20.4 (which we are using in production) the area tree output shows no difference. But the image size and with that the size of the border differs with page-heights from 90mm to 119mm. 90mm is approximately the minimum, otherwise the content does not fit and FOP will generate an unlimited number of pages.
When the page-height is higher then this the image does not get bigger.
The same happens with FOP 0.20.5rc3a.
I've used both JPEG and PNG. No difference with them. So this can rule out JIMI problems if I'm correct.
The weirdest part is that the text below the header image is shown on excactly the same place, even though the image is scaled. I place the header in the region-before and the text below in the region-body.
I've also tried PS output. But it's the same. The image is scaled, but when you lay the two pages on top of each other and the start positions of the images on the same place, the text below the image is at excactly the same place.
I've not attached the PDF previews and XML + XSL files, since this is a mailing list. But if you think you can help me out I'm more then willing to send you the examples + input.
I hope I've given a clear enough explanation of my problem. If you have any questions about this, please contact me.
Regards Wessel van Norel
P.S. can it be that the FOP 0.20.4 Area Tree generation does not work when I run it like this from my JAVA class:
Driver driver = new Driver();
driver.setLogger(log);
driver.setRenderer(Driver.RENDER_XML);
driver.setOutputStream(pdfFile);
driver.render(handler.getParser(), handler.getInputSource());I get a "java.lang.NullPointerException" when I do it, but when I change it from Driver.RENDER_XML to Driver.RENDER_PDF it works...
When I save the generated XML and use FOP from the command line it generates an area tree for me. No nullpointer exception.
