| ImageViewerInteractiveMode | The interactive mode for touch input events in the viewer control. Default value is null. |
To use an interactive mode, you create an instance of any of the derived classes and assign it to the viewer using one of the following methods:
ImageViewer.DefaultInteractiveMode: Assigns the interactive mode to the left mouse button on desktop browsers or default touch events on devices that support touch.
ImageViewer.TouchInteractiveMode: Assigns the interactive mode in devices that support touch.
ImageViewer.SetMouseInteractiveMode: Assigns the interactive mode to the specified mouse button on desktop browsers.
ImageViewer.MouseWheelInteractiveMode: Assigns the interactive mode to the mouse wheel on desktop browsers.
On desktop browsers, you can use multiple interactive modes at the same time. For example, you can use the following code to support panning/zooming with the left mouse button and magnify glass with the right button:
viewer.setMouseInteractiveMode(Leadtools.Controls.MouseButton.left, new Leadtools.Controls.ImageViewerPanZoomInteractiveMode());
viewer.setMouseInteractiveMode(Leadtools.Controls.MouseButton.right, new Leadtools.Controls.ImageViewerMagnifyGlassInteractiveMode());
On browsers that support only touch, such as mobile phones and tablets, you can use only one interactive mode at a time. This does not mean only one finger touch is supported, some of the interactive modes such as ImageViewerPanZoomInteractiveMode supports multiple touch operations such as pinch to zoom.
For an example, refer to SetMouseInteractiveMode.
