Re: Drawing images with PDFDocumentGraphics2D

2003-03-27 Thread Keiron Liddle 
 I was curious and tried your code. Look like the drawImage method in
 question isn't implemented in PDFGraphics2D.java.

This is fixed in cvs, just moved some code.

 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);
 }

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

 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.

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.

Keiron.

 How can I obtain an java.awt.ImageObserver that 
 I can pass to one of the drawImage methods of
 PDFDocumentGraphics2D?
 
 Example:
 
 
  pdfgen = new PDFDocumentGraphics2D(true,System.out,800,1100);
  ...
  pdfgen.drawImage(img,100,100,50,50,imgObserver);
 
 With a pure AWT application, I would pass the java.awt.Panel whose paint 
 method invokes drawImage.
 
 But with PDFDocumentGraphics2D, I don't have such a Panel object.
 Even if I create a surrogate one, the resulting PDF will not have the images in it.
 
 What can act as the ImageObserver?
 
 Thanks,

 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 TestPDFGenx.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.

 Thanks a lot,

 Julio

Drawing images with PDFDocumentGraphics2D

2003-03-25 Thread jcplerm 



How can I obtain an "java.awt.ImageObserver" that 

I can pass to one of the "drawImage" methods 
of
PDFDocumentGraphics2D?

Example:

pdfgen 
= new PDFDocumentGraphics2D(true,System.out,800,1100);
  
...
 
pdfgen.drawImage(img,100,100,50,50,imgObserver);

With a pure AWT application, I would 
passthejava.awt.Panel whose "paint" 
methodinvokes"drawImage".

But with PDFDocumentGraphics2D, I don't have 
such a Panel object.
Even if I create a surrogate one, the resulting PDF 
will not have the images in it.

What can act as the 
"ImageObserver"?
