Re: How to render embedded png?

I am using a file from the Batik Sample folder, "embedData.svg" and still
don't see the embed png.
Below is my whole program. Do you spot any problem? Can it be DOM/SAX
differences? Should I use DOM?
Is there any import missed?
Thanks a lot, the thing is driving me crazy, hope somebody can find
something.
