I wish to only show the road labels when the map reaches a =
pre-determiend scale.I've searched the archives and still baffled.
I realize that this should be a straight forward task, but it has =
defeated me (new to this subject). I load the same
shp files into ArcView and get an idea of when I wish to show/hide the =
labels by playing around with the minumun and maximum
scale values (withn theme->properties dialog). However, nothing seems to =
work on my mapserver. I'm not using php, just wish to set
it up in the map file.
I had originally had the labelling as part of the layer and then created =
a separate annotation layer - still did'nt work.
I'll give you my single layer and see if anyone can assist me on =
showing/hiding the labels for the roads -=20
