Improved map quality

Base maps no longer appear blurry.
Added by Andy Dufilie over 3 years ago

Now when you use a base map in a Map Tool, the zoom level will be adjusted to match one of the fixed zooms supported by the base map. This matches the behavior of all other image-based mapping software. When there is no base map in use, smooth zooming will be available. This new behavior can be disabled in the Map Tool's control panel if smooth zooming with base maps is still desired.
