Summary

Represents a LEADTOOLS PictureBox control for displaying an image.

Syntax
C#
VB
C++
[DefaultPropertyAttribute("Image")] 
[DefaultEventAttribute("FrameChanged")] 
[DockingAttribute(System.Windows.Forms.DockingBehavior)] 
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.
