The angle of the blur relative to the x-axis, in the counterclockwise direction. The units are specified in degrees. The blur kernel is first generated using the same process as for the Gaussian Blur effect. The kernel values are then transformed according to the blur angle using this equation and then applied to the bitmap. offset2D – amount of transformation introduced in the blur kernel as a result of the blur angle. dist – distance from the center of the kernel to the current position in the kernel. offset2d = (dist * cos(??), dist * sin(??) )
