PicturizeSingleCommand Class

Summary

Picturizes the image using a specific thumbnail image.

Syntax

C++

public class PicturizeSingleCommand : RasterCommand

Public Class PicturizeSingleCommand  
   Inherits Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand 
   Implements Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

public ref class PicturizeSingleCommand : public Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand, Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

Remarks

The image, or selected region, is broken down into rectangles of size cell width x cell height. 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 LightnessFactor 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 PicturizeSingleCommand on an image and picturize it with the same image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
public void PicturizeSingleCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg")); 
 
   // Prepare the command 
   PicturizeSingleCommand command = new PicturizeSingleCommand(); 
   command.CellWidth = 20; 
   command.CellHeight = 15; 
   command.LightnessFactor = 200; 
   command.ThumbImage = image; 
   //Picturize the bitmap. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);
