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

Object Model

Syntax

C#
Visual Basic
Objective-C
Java

public class ImageViewerAddRegionInteractiveMode : ImageViewerRubberBandInteractiveMode

'Declaration

Public Class ImageViewerAddRegionInteractiveMode 
   Inherits 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.
