--- layout: example.html title: Magnify shortdesc: Show a magnified version of imager under the pointer docs: >

This example makes use of the `postrender` event listener to oversample imagery in a circle around the pointer location. Listeners for this event have access to the Canvas context and can manipulate image data.

Move around the map to see the effect. Use the ↑ up and ↓ down arrow keys to adjust the magnified circle size.
