Parameters

origin

Center point for all vignette objects (circle, ellipse, rectangle, and square).

fading

Represents the percent of feathering in towards or outward from the vignette object. Negative values mean that the feathering will start outside the boundaries of the object and increase toward the object. Positive values mean that the feathering will start on the boundaries of the object and increase away from the object. Possible values range from -100 to 100.

fadingRate

Represents the value that indicates the fading rate. This value is used to controlling the fading process. It will be divided by 100 internally. The valid range is from 0 to 100.

width

Represents the value that indicates the dimension of the vignette object in pixels.

height

Represents the value that indicates the height in pixels of the vignette ellipse or rectangle objects.This property is ignored if the VignnetCommandFlags.Circle or VignnetCommandFlags.Square flag is set.

vignetteColor

Represents the value that specifies the vignette object color.

flags

Enumeration that specifies how to apply the Vignnet effect.

Run the VignnetCommand on an image.
