Scrolling around the map doesn't change the scale bar.

Goosien shared this problem ago

Solved

The scale should dynamically change when scrolling to different lattitudes. Instead the scale only changes correctly when the zoom changes.

Hi,

The map is a 2D expression of landscape, and its scale is constant within one zoom layer.

Sorry, you're incorrect. Mercator projection maps degrees longitude to a fixed display horizontal width. The distance between those degrees goes to 0 at the poles, so mapping 0 distance to a fixed pixel width trends to an infinite horizontal scale distance.

Also, to keep map objects orientated correctly on the 2d representation, Mercator also changes the number of vertical pixels to lattitude degrees.

Thanks for adding a more exact specification of the problem. Without proper specification, we didn't realize that the problem is related to the Mercator projection. The devs have been informed.
