The OutOfMemory exception is thrown by the system thread.You can override
the 'sun.awt.exception.handler' property to specify your own Outofmemory
error handler.
System.setProperty("sun.awt.exception.handler",
"com.acme.OutOfMemoryErrorHandler");
Your handler would look something like this:
public class OutOfMemoryErrorHandler
{
public void handle(Throwable thrown)
{
if (thrown instanceof java.lang.OutOfMemoryError) {
System.gc();
JOptionPane.showMessageDialog(null, "FATAL ERROR: Not Enough
Memory!");
} else {
thrown.printStackTrace();
}
}
}
You might want to release memory heavy resources by
JSVGComponent.setSVGDocument(null) at this point.
Hope this helps with the Out of Memory issue.

Subject: OutOfMemory exception
I am developing a tool that displays a SVG image(SVGCanvas), after doing 3-5
enlargements I get an Out of Memory exception, a check with
freeMemory()/totalMemory() indicates that there is still a sizable amount
memory available.
I am aware that Batik works on an alternative stack is there any way of
catching the OutOfMemory exception?
Is there a better solution to scrolling a SVG image than to use a SVGCanvas
in a scrollable Panel, I did think about using a JViewport and getting batik
to perform the scrolling, but that seems to be using a sledge hammer to
crack a walnut?
Regards
David.
