then scales objects back to regular resolution to ensure smooth edges.
Canvas Zoom Level
You can zoom in on the Canvas to allow precision alignment and placement of objects,
and you can zoom out to get a sense of the big picture or to see the path of a moving
object. You can also use dynamic zoom modes to zoom in or out of the Canvas, or to
zoom to specific areas of the Canvas. If you have a Multi-Touch device, you can pinch
closed to zoom out and pinch open to zoom in.
Zooming the Canvas does not change the size of the images in your project. It only
changes the view of the entire window.
To zoom in or out on the Canvas
µ
Choose a zoom level from the Zoom Level pop-up menu.

Canvas. The zoom occurs around the spot clicked in the Canvas.
To zoom in and out using a Multi-Touch device

Pinch closed to zoom out or pinch open to zoom in.
After you zoom in, use a two-finger swipe in any direction to scroll around.
