[JAVA2D] getting pixel color information from a rectangle inside a Panel

[Thanasis (Hotmail)]

Hi to everyone, i have built a graphics application using only AWT. Inside a Panel i illustrate a graph which has a number of nodes and arcs (i have drawn THE GRAPH  using g.fillOval and g.drawLine methods). What i want to achieve is to move a red node (circle) from one point P1 inside the Panel to another Point P2. I have done it as follows: ... while (P1!=P2){   draw the node in red color(fillOval)   delay(100ms)   draw the node in white color(fillOval)   move P1 } The problem is that as the node is moving it ERASES any previous pixels lying below it. Is there any way to get the color of these pixels that lie below the moving node and DRAW IT ONLY if those pixels are white?
