I'm stuck and tired.

How can I find the color of an arbitrary pixel of a JPanel or
JComponent for that matter? Something like: getColor(x, y) is all I
really need.

Also while I'm posting is this a cleverer way than color
differentiation (hence the above question) to satisfy an arbitrary
(custom) Shape's contains(Point2D p) method? I let the user draw a
pair of identical CubicCurve2D curves and connect them with a pair of
Line2Ds. I need a good way to determine, for an arbitrary "strip", if
an arbitrary point is in or out of it. I would even settle for a way
to get at all the points Graphics2D fills when I do a
g2.fill(myShape).

[API]

contains(Point2D p)
Tests if a specified Point2D is inside the boundary of the Shape.
