See Also  Example
Leadtools.ImageProcessing.SpecialEffects Namespace > ShadowCommand Class > ShadowCommand Constructor : ShadowCommand Constructor(ShadowCommandAngle,Int32,ShadowCommandType)




angle
Angle value indicating the direction of the light source producing the shadow.
threshold
Threshold value used to determine which pixels will be affected . Valid values range from 0 through 255. When Type = ShadowCommandType.ColoredShadow, any component (R, G, or B) of a pixel with a value less than the Threshold value is not affected. When Type = ShadowCommandType.GrayShadow, any pixel where the master channel value is less than the Threshold value is not affected.
type
Type of the shadow.
Initializes a new ShadowCommand class object with explicit parameters.
