@ -33,6 +33,14 @@ OPENSEADRAGON CHANGELOG
* Added a dragEndHandler event callback, called when a drag gesture ends
* Added a pinchHandler event callback, called as a pinch gesture (2 touch points) is occurring
* Added real-time velocity (speed and direction) tracking to drag operations. 'speed' and 'direction' values are passed in the dragHandler and dragEndHandler event data
* Enhanced Viewer for multi-touch (#369)
* Added pinch zoom with the new MouseTracker pinchHandler
* Added a "canvas-pinch" event fired by the pinch event handler
* Added flick gesture with the new MouseTracker dragEndHandler
* Added a "canvas-drag-end" event fired by the drag-end event handler
* Added a GestureSettings class for per-device gesture options. Currently has settings to enable/disable zoom-on-scroll, zoom-on-click, and flick gesture settings.
* Added GestureSettings objects for mouse, touch, and pen devices to the Viewer options giving users the ability to customize gesture handling in the viewer
* Added velocity (speed and direction) properties to the "canvas-drag" event
