Initializes a new VignnetCommand with explicit parameters.
Syntax
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.
- vignetteColor
- Represents the value that specifies the vignette object color.
- flags
- Enumeration that specifies how to apply the Vignnet effect.
