Intuitively one would believe that the outer edge of the image is the fourth zoom level, but it is not. The fourth zoom level goes from -64,-64 to 1984,1984 and not -1088,-1088 to 960,960 as the image implies.--129.240.118.187 18:45, 23 September 2014 (UTC)

Correction to map alignment. Upload revised version.
This bitmap 1px : 1 square based image corrects the -64,-64 offset example to correctly be at the top left of a 4x magnification map.

The work file (as a GIMP .xcf file) is available, but can't be uploaded. Contact LimestonePlayer for the source file or advise on format. Will monitor page/talk for direction. Limestoneplayer (talk) 18:00, 5 March 2018 (UTC)
