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

Summary

Initializes a new LightCommand class object with explicit parameters.

Syntax

C++/CLI

Python

public LightCommand( 
   LightCommandData[] data, 
   int bright, 
   int ambient, 
   RasterColor ambientColor 
)

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

__init__(self,data,bright,ambient,ambientColor) # Overloaded constructor

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.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void LightConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   LightCommandData[] data = new LightCommandData[1]; 
   data[0] = new LightCommandData(new LeadPoint(image.Width / 2, image.Height / 2), Math.Min(image.Height, image.Width) / 2, Math.Min(image.Height, image.Width) / 2, 0, 100, 0, new RasterColor(255, 255, 255), 100, LightCommandType.Spot); 
   LightCommand command = new LightCommand(data, 100, 100, new RasterColor(255, 255, 255)); 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images"; 
}
