Re: [UMN_MAPSERVER-USERS] How to render current map scale via mapscript?

[David Niergarth]

Thanks Oliver! For Python mapscript it's the attribute mapObject.scale. It is 
documented in the API docs but I had never noticed.

scale is an attribute of mapObj. I don't know for phyton but for java 
its simple: map.getScale()

    Using an html template, I can render the current map scale using

    can I do this from mapscript?

    I'm not using html templates. Instead, I start with a map file,
    instantiate it
    in Python mapscript, add various layers, then render the map and legend.

    I'm trying to tweak my map file (adjusting MAXSCALE, MINSCALE for
    layers) but
    it's tedious without knowing what mapserver thinks the current map
    scale is. Is
    there some simple way to calculate the current scale?

    Thanks for any suggestions,
