Path gradients only work well for convex shapes having only a single figure. You can set the BrushPoint property to change where the center color is centered; the default is new PointF(0.15f, 0.15f), near the top-left corner. You can set the BrushFocusScales property to change the size of the center color area; the default is new SizeF(0.1f, 0.1f).
