Blank images produced by FOP 1.1.
Hello,
I'm trying to upgrade an existing application from fop 0.20.5 to 1.1.
We used to produce BufferedImages by the AWT Renderer. Now I try to make
it right. After lots of searching and trying now I have the following code:
==
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new
StreamSource(
xslt));
setParameter(transformer, parameters, mitarbeiter);
Source src = new StreamSource(new StringReader(xml));
FOUserAgent userAgent = fopFactory.newFOUserAgent();
PageableRenderer renderer = new PageableRenderer(userAgent);
renderer.setScaleFactor(1);
userAgent.setTargetResolution(72);
userAgent.setRendererOverride(renderer);
Fop fop = fopFactory.newFop(userAgent);
Result res = new SAXResult(fop.getDefaultHandler());
transformer.transform(src, res);
List images = new ArrayList();
for (int i = 0; i renderer.getNumberOfPages(); i++) {
BufferedImage pageImage = renderer.getPageImage(i);
images.add(pageImage);
}
==
The problem is, that FOP only produces blank images. I tried, I searched
and I debugged. But I have no glue what's going wrong...
Has anyone any hints?
Thanks
Tobi
P.S. I got the problem solved with 1.0 but this didn't work with Webstart.

Re: Blank Images produced by FOP 1.1.
Hallo Tobias,
Just a random guess, since we had a problem with blank images in FOP 1.1
recently, too. In our case, the culprit was Mac OS X, producing PNG
images with header data that FOP 1.1 disliked. After pumping those
images through ImageMagick convert, FOP found the PNGs much better, and
displayed them properly.
Cheers,
Stefan

Re: Blank Images produced by FOP 1.1.
Hi Stefan,
I tried you hint. It didn't work. But maybe you missunderstood my
problem. The image (actually just a little logo) inside the document is
there (as long as the document is produced as pdf). But when I try to
get a BufferedImage as FOP result there is only a blank image :-( The
hole image is blank. The logo, the text and the tables are missing...
Sorry for the confusion. Propably my first email wasn't clear enough.
Cheers
Tobi
