http://www.eclipse.org/swt/snippets/ has many examples for the problems u are facing...
for the current one this would help

                                Image drawable = new Image(e.display, canvas.getBounds());
				GC gc = new GC(drawable);
				canvas.print(gc);
				ImageLoader loader = new ImageLoader();
				loader.data = new ImageData[] {drawable.getImageData()};
				loader.save("c:\\swt.png", SWT.IMAGE_PNG);
				drawable.dispose();
				gc.dispose();

---------------------
why, mr. Anderson, why, why do you persist?
Because I Choose To.
Regards,
Vijay
