Hi,
I'm trying to render a layer that colors polygons. Three of the classes are
used to color the polygon, and they are mutually exclusive classes (i.e., only
one class at a time will be applicable to a given polygon). The fourth class I
have is meant to draw an outline of the polygon at a certain maxscale value,
otherwise, do not display a border.
What I am getting is that the 'border' class doesn't work with the other three.
If it is the first class in the layer, it totally obstructs the results of the
other three (even though I am making this layer transparent and the style of
the class have a color of -1 -1 -1). If it is the last class, the borders do
not show up at all at any scale. Any advice or clarification on my
misunderstanding of how Mapserver is operating would be appreciated. Below is
the relevant layer:
