[mapserver-users] RE: legend not visible with maxscaledenom set

[Bistrais, Bob]

I am now finding that, with the MaxScaleDenom set, if the layer is
turned off until you zoom into the MaxScaleDenom, the legend will
display when you turn it on.  If you have the layer on when outside the
maxscaledenom, then zoom into the visible range, the legend does not
show unless you turn the layer off, then on again.  This is starting to
look more like an issue in the GeoMoose software now.

How are you creating the legend? One work-around would be to fake a map
associated with a call to create a legend. That is, set EXTENT and SIZE
to values that would generate a computed scale below your MaxScaleDenom.
I've done that when using mode=legend where you set mapext and mapsize
as needed. Otherwise we'd really need to implement an override parameter
(perhaps a processing directive) to ignore scale when compiling the
legend.

This appears to be an old problem, but I am still having trouble with it
in MapServer 6.0.2.   If I have a layer without a Maxscaledenom set, the
layer legend displays properly.  But if I set the Maxscaledenom, the
legend does not appear in my application.  This happens when
Maxscaledenom is set at the layer level or the class level.

 

I've looked though the archives and have seen this problem since version
5, but don't see a resolution for MS 6.
