Pinchable layers

A pinchable layer can be scaled and rotated with two fingers. It’s an interaction you often see in mapping apps where it’s used to rotate the map or zoom in or out.

How to make a layer pinchable? Simple, you enable it, just like draggable:

layerA.pinchable.enabled = yes

You can even combine the two and have a layer that you can rotate, resize and also drag around.

layerA.pinchable.enabled = yes
layerA.draggable.enabled = yes

On the desktop, you can hold down ⌥ to see a second cursor appear. To drag a layer while simultaneously pinching it, hold down ⌘.

Pro tip: To maintain a high enough resolution when scaled up, use a bigger layer and scale it down. In the above example, I doubled the size of the layer and set its initial scale to 0.5.
