Remarks

ImageViewerCenterAtInteractiveMode derives from ImageViewerInteractiveMode and subscribes to the following events of the InteractiveService:

This interactive mode uses ImageViewer.CenterAtPoint to center the image inside the viewer based on the tap event. Additionally, if the value of ScaleFactor is anything other than the default value of 1, then this mode will zoom in (if the value is greater than 1) or zoom out (if the value is less than 0) the image as well around the same center point.

When responding to a tap event, this mode will set InteractiveEventArgs.IsHandled to true.

For more information, refer to Image Viewer Interactive Modes.

Example

For an example, refer to ImageViewer.InteractiveModes.
