public ShadowCommand( 
   ShadowCommandAngle angle,
   int threshold,
   ShadowCommandType type
)

'Declaration
 
Public Function New( _
   ByVal angle As ShadowCommandAngle, _
   ByVal threshold As Integer, _
   ByVal type As ShadowCommandType _
)

'Usage
 
Dim angle As ShadowCommandAngle
Dim threshold As Integer
Dim type As ShadowCommandType
 
Dim instance As New ShadowCommand(angle, threshold, type)

public ShadowCommand( 
   ShadowCommandAngle angle,
   int threshold,
   ShadowCommandType type
)

function ShadowCommand( 
   angle ,
   threshold ,
   type 
)

public:
ShadowCommand( 
   ShadowCommandAngle angle,
   int threshold,
   ShadowCommandType type
)

Parameters

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.
