I tried the following but the image now no longer draws...
	AffineTransform at =3D new AffineTransform(rect.getWidth(), 0, 0, rect.get=
Height(), rect.getLowerLeftX(), rect.getLowerLeftY());
	PDPageContentStream canvas =3D new PDPageContentStream(document, page, PDP=
ageContentStream.AppendMode.APPEND, true, true);
	at.rotate(Math.toRadians(90));
	canvas.saveGraphicsState();
	canvas.transform(new Matrix(at));
	canvas.drawImage(ximage, rect.getLowerLeftX(), rect.getLowerLeftY());
	canvas.restoreGraphicsState();
	canvas.close();

Did I misunderstand something?

As for the imaging squishing I am seeing. It looks to me like the rectangle=
 size / position of the image non rotated stays exactly the same but the co=
ntents are rotated and squished. I can send you a couple pdfs showing what =
I mean (direct email?). And maybe that is how it is supposed to work, but I=
 would of expected the image to look exactly the same just rotated. In case=
 of 90 degrees, like the example above, I would of expect simply the width =
to become the height and the height to become the width.

Sorry I don't understand you... why should it not keep the size?

ble to find a drawImage method that takes AffineTransform. What is the reco=
mmended way to do this in 2.0 going forward?

         saveGraphicsState();
         transform(new Matrix(transform));  <=3D=3D do the rotation only

          drawImage()     <=3D=3D=3D here just set the position

         restoreGraphicsState();
