PicturizeListCommand Class

Summary

Picturizes the image using a specific thumbnail image.

Syntax

C++

public class PicturizeListCommand : RasterCommand

Public Class PicturizeListCommand  
   Inherits RasterCommand

public ref class PicturizeListCommand : public RasterCommand

Remarks

The image, or selected region, is broken down into rectangles of size CellWidth x CellHeight. For each rectangle, the thumbnail image is corrected to approximate that rectangle, and inserted in the original image. Note that every rectangle is replaced by the same image.
The lightness factor can be used to change the lightness of the big image by changing the lightness of each rectangle.
This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
This command does not support signed data images.
This command does not support 32-bit grayscale images.

Example

Run the PicturizeListCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
public void PicturizeListCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg")); 
   RasterImage image1 = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp")); 
   RasterImage image2 = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Image2.cmp")); 
 
   image.AddPage(image1); 
   image.AddPage(image2); 
 
   // Prepare the command 
   PicturizeListCommand command = new PicturizeListCommand(); 
   command.CellHeight = 20; 
   command.CellWidth = 15; 
   command.LightnessFactor = 200; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);
