	int radius
)

Parameters

x
Type: System..::.Int32
X coordinate of central point of the rectangle.
y
Type: System..::.Int32
Y coordinate of central point of the rectangle.
radius
Type: System..::.Int32
Radius of the rectangle.

Return Value

Returns mean value of pixels in the specified rectangle.
