[mapserver-users] how do min/max scale filters work?

[Stephen Woodbridge]

Does it draw if you remove both (MAX|MIN)SCALEDENOM?
If not the problem is probably not related to these.

However, I’ve had no luck using the MAXSCALEDENOM and MINSCALEDENOM keywords. As configured below, the layer never draws, regardless of the scale. The layer draws correctly if I comment out the scale tests. Can anyone show me the correct way to use this?
