This issue is really annoying. I remember that the performance was much
better on Panther using the different color model as described in

Too bad, to discover that it's slow again on Tiger ...
It would really help if the apple engineers could work on that issue.

Too bad.
thomas, is there any chance you'll be able to revise how batik
uses BufferedImage/WritableRaster to avoid this performance hit?
There is essentially no way to fix this in all of Batik.
Much of Batik is built around the java.awt.image.RenderedImage
interface. In this interface an image is composed of tiles which
are rasters, so you basically can't avoid touching the rasters that
are used to build BufferedImages for rendering.
There is some chance that the use of Rasters/RenderedImages
might be avoided in the 'DynamicRenderer' which would help for
simple things but I think that you would find that most content
would 'trip' over the raster access.
