Question

Is anybody know how to get a Color from pixel.
My program is not Full Screen .
So i think Robot.getPixelColor() don't suitable.
Please Help me!

Answer 1

Robot.getPixelColor() will work fine, but the problem you will have is getting the mouse set to the correct location and getting your application to know where it is: you can do it with win32 calls and JNI. Here are a few that I have found helpful--they are in a VB format:
Public Const CLR_INVALID = &HFFFF 'not a valid pixel
Public Const MOUSE_MOVED = &H1
Public Const MOUSEEVENTF_ABSOLUTE = &H8000 ' absolute move
Public Const MOUSEEVENTF_LEFTDOWN = &H2 ' left button down
Public Const MOUSEEVENTF_LEFTUP = &H4 ' left button up
Public Const MOUSEEVENTF_RIGHTDOWN = &H8 ' right button down
Public Const MOUSEEVENTF_RIGHTUP = &H10 ' right button up
Public Const REQUEST_LEFT_CLICK = &H2D 'request left click "-"
Public Const REQUEST_RIGHT_CLICK = &H2B 'request right click "+"
