Syntax

Visual Basic (Declaration)  
Public Class CropCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage) Copy Code
Dim instance As CropCommand
C#  
public class CropCommand : RasterCommand, IRasterCommand 
C++/CLI  
public ref class CropCommand : public RasterCommand, IRasterCommand 

Example

This example trims 100 pixels off of each side of an image.

Visual Basic Copy Code
Public Sub CropCommandExample()
 RasterCodecs.Startup()
 Dim codecs As RasterCodecs = New RasterCodecs()

 Dim srcFileName As String = LeadtoolsExamples.Common.ImagesPath.Path + "Image1.cmp"
 Dim destFileName As String = LeadtoolsExamples.Common.ImagesPath.Path + "CropCommand.bmp"

 ' Load the source image from disk
 Dim image As RasterImage = codecs.Load(srcFileName)

 ' Crop 100 pixels from each side of the image
 Dim command As CropCommand = New CropCommand()
 command.Rectangle = New Rectangle(100, 100, image.Width - 100, image.Height - 100)
 command.Run(image)

 ' Save it to disk
 codecs.Save(image, destFileName, RasterImageFormat.Bmp, 24)

 ' Clean Up
 image.Dispose()
 RasterCodecs.Shutdown()
      End Sub
C# Copy Code
public void CropCommandExample() 
{ 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
 
   string srcFileName = LeadtoolsExamples.Common.ImagesPath.Path + "Image1.cmp"; 
   string destFileName = LeadtoolsExamples.Common.ImagesPath.Path + "CropCommand.bmp"; 
 
   // Load the source image from disk 
   RasterImage image = codecs.Load(srcFileName); 
 
   // Crop 100 pixels from each side of the image 
   CropCommand command = new CropCommand(); 
   command.Rectangle = new Rectangle( 
      100, 
      100, 
      image.Width - 100, 
      image.Height - 100); 
   command.Run(image); 
 
   // Save it to disk 
   codecs.Save(image, destFileName, RasterImageFormat.Bmp, 24); 
 
   // Clean Up 
   image.Dispose(); 
   RasterCodecs.Shutdown(); 
}

Remarks

If a region is defined for the image, the region is also cropped if necessary.
