RasterPictureBox Class

Summary

Represents a LEADTOOLS PictureBox control for displaying an image.

Syntax

C++/CLI

[DockingAttribute(System.Windows.Forms.DockingBehavior)] 
[DefaultEventAttribute("FrameChanged")] 
[DefaultPropertyAttribute("Image")] 
public class RasterPictureBox : Control, INotifyPropertyChanged

public: 
   [DefaultEventAttribute(L"FrameChanged"),  
   DockingAttribute(System::Windows::Forms::DockingBehavior),  
   DefaultPropertyAttribute(L"Image")] 
   ref class RasterPictureBox : Control, INotifyPropertyChanged

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 Multipage file formats.
