ImageViewerZoomAtInteractiveMode Object


Zooms the image inside the viewer around the user's mouse click or touch tap.

function lt.Controls.ImageViewerZoomAtInteractiveMode 
	extends lt.Controls.ImageViewerInteractiveMode 
class lt.Controls.ImageViewerZoomAtInteractiveMode() 
	extends ImageViewerInteractiveMode 


The ImageViewerZoomAtInteractiveMode object derives from the ImageViewerInteractiveMode object and subscribes to the following events of the InteractiveService:

When a valid tap event occurs and InteractiveEventArgs.isHandled is false, this interactive mode will start working and set InteractiveEventArgs.isHandled to true.

This interactive mode uses ImageViewer.zoom to zoom the image inside the viewer based on the tap event. If the value of ScaleFactor is greater than 1, then the viewer will zoom the image in. If the value of ScaleFactor is less than 1, then the viewer will zoom the image out.

For more information, refer to Image Viewer Interactive Modes.


For an example, refer to ImageViewer.InteractiveModes.
