title: Pinch Zoom
shortdesc: Restrict pinch zooming to integer zoom levels.
docs: >
  By default, the `ol.interaction.PinchZoom` can leave the map at fractional zoom levels.
  If instead you want to constrain pinch zooming to integer zoom levels, set
  <code>constrainResolution: true</code> when constructing the interaction.
