Example

This example loads a 16-bit grayscale image and then colors it.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core;

{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Beauty16.jpg")); 
 
   // Prepare the command 
   ColorizeGrayCommandData[] grayColors = new ColorizeGrayCommandData[6]; 
 
   RasterColor[] colors = new RasterColor[6];

   //Call the command 
   command.Run(image); 
 
   // Save the resulted image
