LightCommand Constructor(LightCommandData[],int,int,RasterColor)

Summary

Initializes a new LightCommand class object with explicit parameters.

Syntax
C#
VB
C++
  
Public Function New( _ 
   ByVal data() As LightCommandData, _ 
   ByVal bright As Integer, _ 
   ByVal ambient As Integer, _ 
   ByVal ambientColor As RasterColor _ 
) 
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.
