ImageViewerAddRegionInteractiveMode Class

Summary

Adds a region to the image using rubber-banding, and optionally converts it to a floater.

Syntax

C++

public class ImageViewerAddRegionInteractiveMode : ImageViewerRubberBandInteractiveMode

Public Class ImageViewerAddRegionInteractiveMode 
   Inherits ImageViewerRubberBandInteractiveMode

public ref class ImageViewerAddRegionInteractiveMode : ImageViewerRubberBandInteractiveMode

Remarks

ImageViewerAddRegionInteractiveMode derives from ImageViewerRubberBandInteractiveMode. When the rubber-band operation is completed (OnRubberBandCompleted), the mode will add a region to the current item Image object.

The region added shape depends on the value of ImageViewerRubberBandInteractiveMode.Shape, and the mode will call the various RasterImage region methods to create this region.

If the value of AutoRegionToFloater is true, then this region will be automatically converted to a floater using ImageViewerItem.ImageRegionToFloater, and the region is deleted from the image. After that, you can use ImageViewerFloaterInteractiveMode to move and resize the floater.

For more information, refer to Image Viewer Interactive Modes.
