Getting visible image displayed on JSVGCanvas

[Web Query <we...@shermantech.com>]

Hi All,

I imagine there is a very simple solution for what I am trying to do 
here.  I would like to get a BufferedImage of what the JSVGCanvas is 
currently displaying.  I have looked into using an ImageTranscoder, but 
I am not clear on exactly how to link the transcoder to the JSVGCanvas 
in order to get a BufferedImage.  Ideally, I am hoping there is some 
function call buried in the JSVGCanvas parent classes that will just 
return the currently displayed BufferedImage.

What is the best way to go about this?

Thanks,
Chris| |||

I think getGraphicsNode() (in JGVTComponent) and casting it to a 
Graphics (which can be transformed in an image real easy. Check the 
javadoc) should help you out. Note however that the loading process in 
SVGCanvas is asynchronous. It might not be what you want.
