Richard,
sorry, yes, sure...
Perhaps you can use scaletoken? It's not the same as you are searching
for, but you could define a set of tolerance-values for different scales.

Hi,
what about:
https://mapserver.org/mapfile/template.html#image-geometry
<https://mapserver.org/mapfile/template.html#image-geometry>
-> scaledenom
Doesn't work?
Thanks, but no, it does not work. I'm trying to access the scale in a
map file, not in a template. Using square brackets [variable] is
interpreted as a field name in the data, not as a runtime variable. For
example:
CLASS
STYLE
GEOMTRANSFORM (generalize([shape], [scaledenom]))
COLOR "#2AB1F7"
END
END
returns the error:
DBASE file error. Item 'scaledenom' not found.
