WorldWind color at pick point

Question

I'm trying to figure out a way to programmatically get the visual color (not the picking color) of the point where a user clicks on a WorldWind AnalyticSurface.

Looking at AnalyticSurface and PickedObjectList I'm not sure of what API calls I need to string together to do this or if its even possible.

Answer 1

Here is a possible solution. Just try. When clicked, (i assume you have made some MouseListener object with a mouseClicked() method in it), just get the current mouse pointer location on the whole computer screen as co-rdinate.

import java.awt.MouseInfo;
import java.awt.PointerInfo;
import java.awt.Point;
PointerInfo pi=MouseInfo.getPointerInfo();
Point p=pi.getLocation();

Now we got the position of point clicked on screen.

Using Robot class you can get the pixel at the location.

import.java.awt.Robot;
import.java.awt.Color;
Robot robot=new Robot();
Color color=robot.getPixelColor(p.x,p.y) ;
// you got the color at the clicked point.

Hope this helps.
