public class DirectionalBlur : Effect, IDisposable, IUnknown

Public Class DirectionalBlur
    Inherits Effect
    Implements IDisposable, IUnknown

Name	Description
DirectionalBlur(nint)	Initializes a new instance of the DirectionalBlur class.

Name	Description
Angle	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(??) )
BorderMode	The mode used to calculate the border of the image, soft or hard. See BorderMode modes for more info.
Optimization	The optimization mode. See DirectionalBlurOptimization modes for more info.
StandardDeviation	Gets or sets the amount of blur to be applied to the image. Default: 1.0f

Name	Description
Create(DeviceContext)	Initializes a new instance of DirectionalBlur effect.
