LightCommand Constructor(LightCommandData[],Int32,Int32,RasterColor)
See Also  Example
Leadtools.ImageProcessing.SpecialEffects Namespace > LightCommand Class > LightCommand Constructor : LightCommand Constructor(LightCommandData[],Int32,Int32,RasterColor)



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.
Initializes a new LightCommand class object with explicit parameters.

Syntax

Visual Basic (Declaration)  
Public Function New( _
   ByVal data() As LightCommandData, _
   ByVal bright As Integer, _
   ByVal ambient As Integer, _
   ByVal ambientColor As RasterColor _
)
Visual Basic (Usage) Copy Code
Dim data() As LightCommandData
Dim bright As Integer
Dim ambient As Integer
Dim ambientColor As RasterColor
 
Dim instance As LightCommand(data, bright, ambient, ambientColor)
C#  
public LightCommand( 
   LightCommandData[] data,
   int bright,
   int ambient,
   RasterColor ambientColor
)
C++/CLI  
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.

Example

Run the LightCommand on an image to change the red color by rotating its hue 90 degree.
