ImageViewerPanControl Class


Supports displaying a scaled view of an ImageViewer into an external control with panning support.


public class ImageViewerPanControl : IDisposable 
Public Class ImageViewerPanControl 
public ref class ImageViewerPanControl 


The ImageViewerPanControl is used to display a scaled view of an image, which is also being displayed in the ImageViewer control on an external target control at a size that would require scrolling. ImageViewerPanControl will maintain the images aspect ratio. A colored pan rectangle will be displayed to indicate the portion of the image currently being displayed in the viewer associated with this pan control.

By default, when the user clicks inside the pan control and drags using the mouse or touch, the pan rectangle will move with it.
