Bump Distortion Spatial Photo Filter

This filter creates a bump distortion effect by warping the image around a specified point. It is often used to create a 3D-like effect.

Parameters

• Center: The center of the bump distortion effect. This parameter controls the point around which the image will be warped.

• Radius: The radius of the bump distortion effect. This parameter controls the extent of the distortion applied to the image.

• Angle: The angle of the bump distortion effect. This parameter controls the direction of the distortion applied to the image.

• Scale: The scale of the bump distortion effect. This parameter controls the intensity of the distortion applied to the image.
