Angle Property
See Also  Example
Leadtools.ImageProcessing.SpecialEffects Namespace > FunctionalLightCommand Class : Angle Property



Gets or sets a value that represents the angle, in hundredths of degrees.

Syntax

Visual Basic (Declaration)  
Public Property Angle As Integer
Visual Basic (Usage) Copy Code
Dim instance As FunctionalLightCommand
Dim value As Integer
 
instance.Angle = value
 
value = instance.Angle
C#  
public int Angle {get; set;}
C++/CLI  
public:
property int Angle {
   int get();
   void set (int value);
}

Return Value

Value that represents the angle, in hundredths of degrees. This property is used if the Flags property is set to FunctionalLightCommandFlags.Trigonometry or to FunctionalLightCommandFlags.Freehand. Valid values for this property range from -18000 to 18000. This value is divided internally by 100.

Example

Run the FunctionalLightCommand on an image.
