Gaussian 2D blurs an image in two perpendicular directions like the usual XY blur, but here you can also control the directions angle. This allows you to get maximum blur in any desired direction. Parameters: Size D1 Controls the blur power in D1 direction. Value of 1.0 sets the maximum blur, but you can enter in edit field values up to 4.0 and get more blur, but with a slightly reduced quality. Size D2 Controls the blur power in D2 direction. Value of 1.0 sets the maximum blur, but you can enter in edit field values up to 4.0 and get more blur, but with a slightly reduced quality. Angle Controls the blur angle. If the angle is 0.0, D1 is horisontal. Value of 1.0 = one full rotation (360 degree). See also Gaussian Blur variations: Gaussian Blend - Blur an image and blend with the original. Variable size - control the blur power within the frame with a Radial Mask, or Linear Mask.
