Beanshell:Create an image layer from a file or URL

This awesome idea was requested by Andrew Collins and took me two hours to write. It's a BeanShell script to create an image layer from a GIF, JPEG, or PNG file or URL

1. Click View > BeanShell.
2. Copy the code below into the clipboard.
3. Paste the code into the BeanShell window with Ctrl+V. JUMP will create the image layer!

{
minx = 100; maxx = 952; miny = 100; maxy = 489; //Image coordinates
filenameOrURL = new
URL("http://www.apsu.edu/field_biology/center/sym2001/fig1p66.jpg");
//filenameOrURL = "c:/junk/Arrow.jpg";
layerName = "Image";
image = Toolkit.getDefaultToolkit().getImage(filenameOrURL);

mediaTracker = new MediaTracker(wc.layerViewPanel);
mediaTracker.addImage(image, 0);
mediaTracker.waitForID(0);
envelope = new Envelope(minx, maxx, miny, maxy);
wc.layerManager.addLayer(StandardCategoryNames.WORKING, layerName,
FeatureDatasetFactory.createFromGeometry(
Collections.singleton(EnvelopeUtil.toGeometry(envelope))))
.addStyle(new Style() {
public void paint(Feature f, Graphics2D g, Viewport viewport) {
originalTransform = g.getTransform();
try {
xScale = viewport.scale*envelope.width/image.getWidth(null);
yScale = viewport.scale*envelope.height/image.getHeight(null);
g.scale(xScale, yScale);
upperLeftCorner = viewport.toViewPoint(new Coordinate(minx, maxy));
g.translate(upperLeftCorner.x/xScale, upperLeftCorner.y/yScale);
g.drawImage(image, 0, 0, null);
}
finally {
g.setTransform(originalTransform);
}
}
public void initialize(Layer layer) {}
public Object clone() { throw new UnsupportedOperationException(); }
public void setEnabled(boolean enabled) {}
public boolean isEnabled() { return true; }
});
wc.layerManager.getLayer(layerName).getBasicStyle().renderingFill = false;
