Description

In Print Composer's Item Properties pane is a Scale field. The meaning of this field is not explained. All I can figure out is if I reduce the number in it, that zooms in within the currently-selected item.

Note that this is not a support request. This is a feature request for the UI to do a better job explaining what this field means. I guess it has something to do with the number of projection units displayed on the horizontal dimension of the viewport of the item, but I am not sure.

This should be a blocker - something has broken the scale calculation for composer map items, and numerical scale bars based off the map also reflect an incorrect value.

Actually - I've tracked down the problem I was experiencing - I had changed the CRS for a project, but the map extents in the composer retained the old coordinate system's values. Updating the extent fixed the scale problems I was having.

Aren - does this sound similar to what you are seeing, or is this a different issue? What values are you seeing for your map scales?

I do have a project CRS specified, and Enable 'on the fly' CRS transformation is selected.

I'm seeing 360795 in Scale in the Print Composer. Extents are:
  • X min: 1254970.060
  • Y min: 1160240.042
  • X max: 1350219.940
  • Y max: 1226794.977
