Hello, world!

My application requires cropping some thumbnails. I tried searching the internet and this forum, and only came up with this:

http://www.eclipse.org/forums/index.php?t=msg&th=107998# msg_330182

The solution presented requires converting the ImageData to an AWT BufferedImage, which I'm sure is inefficient. Manipulating x, y, width, and height do not appear to have an effect. How does one go about this? GC?

Thanks

Never mind, I got it figured out. GC was the key as I suspected. Here's an example of what I did, for future reference.

// Image image
Image newImage = new Image(null, thumb_width, thumb_height);
GC gc = new GC(newImage);

gc.drawImage(image, crop_left, crop_top, image.width - (crop_right * 2), image.height - (crop_bottom * 2), height, 0, 0, thumb_width, thumb_height);
gc.dispose();
