public class ImageViewerPagerInteractiveMode : ImageViewerInteractiveMode
'Declaration
Public Class ImageViewerPagerInteractiveMode Inherits ImageViewerInteractiveMode
ImageViewerPagerInteractiveMode derives from ImageViewerInteractiveMode and subscribes to the following events of the InteractiveService:
This mode in two modes:
If the value of ChangeActiveItem is true. Then when the user clicks and drags on the viewer surface, the current active item index changes in the viewer accordingly.
If the value of ChangeActiveItem is false. Then when the user clicks and drags on the viewer surface, the current page number in the item being used (Item) will change. This only works if the item has a valid image in Image and if it has multiple pages.
In both cases, this mode works by calculating the maximum change for the operation (either number of items when changing the active item or number of pages in RasterImage.PageCount when changing the page number). Then normalizing this value across the current height of the viewer. When the user clicks and drags on the viewer, the value changes based on the current location. Dragging up will decrease value while dragging down will increase the value.
For more information, refer to Image Viewer Interactive Modes.
