'Declaration
 
Public Function New( _
   ByVal data() As LightCommandData, _
   ByVal bright As Integer, _

   LightCommandData[] data,
   int bright,
   int ambient,
   RasterColor ambientColor
)

function LightCommand( 
   data ,
   bright ,
   ambient ,
   ambientColor 
)

public:
LightCommand( 
   array<LightCommandData>^ data,
   int bright,
   int ambient,
   RasterColor ambientColor
)

Parameters

data: An array of LightCommandData structures that contains information on each light source.
bright: Value that represents the brightness of the ambient light of the entire image. This can be any number that is 0 or greater. If it is 0 the image will be black. This value is divided internally by 100.
ambient: Factor used when mixing the ambient color with the image. This property only accepts positive values.
ambientColor: Specifies the ambient color of the light sources in the LightCommandData array.
