[Qgis-user] Map Scale text in composer

[Carlos Cerdán]

Hi Randal:


The label expression:


[% '1 inch to ' || (to_int( $scale )/12) || ' Feet'%]


must work... but I got "1 inch to 0 Feet".  $scale help says: "This
function is only available in some contexts and will be 0 otherwise". ....
Which contexts?

Developers, please light us.
