Creating a BufferedImage from a 3D view shown in an AWT Canvas

Troubleshooting gui
1

Hi,



I'm creating an AWT canvas showing a 3D view using the createCanvas method as follows:       


Canvas canvas = DisplaySystem.getDisplaySystem( "lwjgl" ).createCanvas( width, height );



How do I get a BufferedImage (or just Image) of the content of the canvas?

If I try to call canvas.paint( myBufferedImage.getGraphics() )  I just get a transparent image.

If I use BufferedImage image = (new Robot()).createScreenCapture( screenRegionOf3DView ); I also get any other top level window on the image, such as Java dialogs, floating toolbars, as well as operating system windows.
