Actually, something a bit simpler could do the trick, like:
Component dummyComponent = new Canvas();
and then straight ahead into:
Image image = dummyComponent.getImage(filename);
or
Image image = dummyComponent.createImage(
new MemoryImageSource(width,height, pixels, 0,width) );
But if you are on Linux, see another message by Chris, because importing
java.awt.* won't mean that you DO have a native peer. Relying on the
existance of native peers is quite a headache at times.
