Members

Value	Member	Description
0	None	Default, no user interaction.
1	Pan	Allows the user to pan the image using the cursor. The ImageViewer.InteractivePan event will fire one or more times during this mode with the current locations and status of the operation. In this mode, the control will position the scrollbars according to user cursor moves, therefore, this mode is only functional if the control has visible scrollbars (SizeMode is SizeMode.Normal or SizeMode.FitWidth and the viewport is less than the image size).
2	CenterAt	Centers the image at the mouse coordinates for the last user click. The ImageViewer.InteractiveCenterAt event will fire one or more times during this mode with the current locations and status of the operation. In this mode, the control will position the scrollbars according to user cursor clicks, therefore, this mode is only functional if the control has visible scrollbars (SizeMode is SizeMode.Normal or SizeMode.FitWidth and the viewport is less than the image size).
3	ZoomTo	Zooms the image to the rectangle created by the user. The ImageViewer.InteractiveZoomTo event will fire one or more times during this mode with the current locations and status of the operation.
4	Scale	Allows the user to change the current scale factor of the image using the mouse. The ImageViewer.InteractiveScale event will fire one or more times during this mode with the current locations and status of the operation.
5	MagnifyGlass	Starts the MagnifyGlass. The ImageViewer.InteractiveMagnifyGlass event will fire one or more times during this mode with the current locations and status of the operation.
6	UserRectangle	User-defined rectangle. You should subscribe to the ImageViewer.InteractiveUserRectangle event to add your custom code to handle the rectangle drawn.

Remarks

The ImageViewer and RasterImageViewer supports many interactive modes for user interaction with the cursor. To enable any of the interactive modes, set the ImageViewer.InteractiveMode property to any of the InteractiveMode enumeration members. Subsequent cursor down, move and up operations will be captured by the control to perform the required interactive mode.

Various events will occur during the interactive modes to allow you to get information, alter values, or cancel the operation all together.
