I'm trying to load a gif image from a url into a java.util.image.Raster so I can manipulate it. The only method for loading and decompressing an image I could find was Toolkit.getImage, which returns a java.awt.Image. I need to turn that into a Raster so I can work with it. Suggestions?

A:
Load your Image into a Buffered Image and then get the data from it
BufferedImage img = null;
try {
img = ImageIO.read(new File ("c:/imageFile.gif"));
} catch(Exception e) {}
Raster R=img.getData();

A:
if you just want to draw on this image, you can get a Graphics2D context, from your BufferedImage.
Graphics2D g=(Graphics2D) image.getGraphics();
//draw over your image
g.drawLine(1,1,100,100);
g.dispose();
//save your image, display it, etc...

Rickster sent me down the right path (thanks!).
import javax.imageio.ImageIO;
public Raster get_image(InputStream inp) {
return ImageIO.read(inp).getData();
}
public Raster get_image(URL inp) {
return ImageIO.read(inp).getData();
}
