This is fixed in cvs, just moved some code.

The TestPDFGen now works with both draw image methods provided you wait on
the observer as above.

Re: Drawing images with PDFDocumentGraphics2D
I was curious and tried your code. Look like the drawImage method in
question isn't implemented in PDFGraphics2D.java.
I modified your code and got a image in PDF when I did the following:
while(!PDFGenerator1.drawImage(img, 400, 300, panel)) {
Thread.sleep(200);
}
Not in the right place and with the right size, but the image
nonetheless. Looks like Graphics2D.java still needs a little work.
Also, maybe using System.out to create PDFs using FOP may not be the
best idea because there are still some System.out.println statements
scattered around the codebase.
Maybe that helps.

Re: Drawing images with PDFDocumentGraphics2D
Keiron, I am sending attached to this message a small test case that should reproduce the problem. I am loading the image with "Toolkit.getDefaultToolkit().getImage" and then I pass that image to the "drawImage" method, along with "new Panel()" as an observer. By running "java TestPDFGen>x.pdf" I get only a single square on the page, without the image. I would be very grateful if you could take a look into this and see what I am doing wrong.

Re: Drawing images with PDFDocumentGraphics2D
Hi, The ImageObserver is used in the getWidth, getHeight and drawImage methods with the image that is passed in. So in a sense it depends on the img that you are passing in. The observer is an object waiting for the image to be loaded. How are you creating the image, can you get an abserver from there somehow. Maybe you could use a dummy observer if the image is already loaded.
