Hi Olver,
I have never gotten this Exception, but we don't use
Java2D much. I have put a try clause around line 578
of VisADCanvasJ2D.java as follows:
try {
g2.drawImage(image, 0, 0, this);
} catch (java.awt.image.ImagingOpException e) { }
Until my next release, you can find the updated code at:
ftp://ftp.ssec.wisc.edu/pub/visad-2.0/untested/VisADCanvasJ2D.java
Please let us know if this does not fix your problem.
Cheers,
Bill
