Yes, they switched from the Quartz rendering pipeline to the Sun
rendering pipeline and the performance sucks. I've already posted a
bug report to Apple about it.
In the meantime switch to the Quartz rendereing pipeline with the
following command line switch:
-Dapple.awt.graphics.UseQuartz=true

Hi!
I have the following code to downscale images:
// Do the scaling
BufferedImage reducedImage = new BufferedImage(newX, newY,
BufferedImage.TYPE_INT_RGB);
Graphics2D g = reducedImage.createGraphics();
g.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
RenderingHints.VALUE_INTERPOLATION_BICUBIC);
g.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
RenderingHints.VALUE_ANTIALIAS_ON);
g.setRenderingHint(RenderingHints.KEY_RENDERING,
RenderingHints.VALUE_RENDER_SPEED);
NSLog.out.appendln("Drawing image with original dimensions " +
originalImage.getWidth() + ", " + originalImage.getHeight()
+ " with size " + newX + ", " + newY ); */
g.drawImage(originalImage, 0, 0, newX, newY, 0, 0,
originalImage.getWidth(), originalImage.getHeight(), null);
g.dispose();
The log is: INFO 00:27:16 (NSLog :38) -Drawing
image with original dimensions 3072, 2304 with size 267, 200
This took about a second to process in my Powerbook on Tiger. I
migrated to Leopard, and this is taking... well... forever. I waited
several minutes and it's still sucking up my CPU. Shark says it's
taking a lot of time in color conversion stuff:

I have no ideia why. It's the same image and the same code. Only
the OS has changed. Another Leopard bug?
Any ideias?
