Summary

Represents a LEADTOOLS PictureBox control for displaying an image.

Syntax
C#
VB
C++
[DefaultPropertyAttribute("Image")] 
[DockingAttribute(System.Windows.Forms.DockingBehavior)] 
[DefaultEventAttribute("FrameChanged")] 
public class RasterPictureBox : Control, INotifyPropertyChanged 
<DefaultEventAttribute("FrameChanged"),  
 DockingAttribute(System.Windows.Forms.DockingBehavior),  
 DefaultPropertyAttribute("Image")>  
Public Class RasterPictureBox 
   Inherits System.Windows.Forms.Control 
public [DefaultEventAttribute(L"FrameChanged"),  
   DockingAttribute(System::Windows::Forms::DockingBehavior),  
   DefaultPropertyAttribute(L"Image")] 
   ref class RasterPictureBox : System::Windows::Forms::Control 

Remarks

The RasterPictureBox is used to display graphics from a bitmap, metafile, icon, JPEG, GIF, or PNG (or any other image file format supported by LEADTOOLS) file.

Set the Image property to an RasterImage object to be displayed.

The RasterPictureBox control can automatically animate Multi-Page file formats.
