[Mapserver-users] A STYLE with no COLOR is hardly a STYLE

[Pericles S. Nacionales]

Ryan,

I see your point but in Tyler's defense, he did say workaround.  Perhaps
you should file a feature request/bug report in bugzilla.  If you can
convince Steve and the other developers then you might have it quickly. 
I do like the idea of being able to define the polygon outline style in
the same style as the polygon fill.

But here's another work around.  Or, as I'd prefer to call, an
alternative method: 1. Define your layer as polygon but don't define an
outline color.  2. Create another layer from the same data but define
TYPE as line, also call it the same layer name (or define a GROUP name
for the two layers).  Define your line STYLE on this layer.

Now, when you select the layer name, both of the layers are drawn.

So, while I like your idea I think the alternative I just showed you is
pretty flexible.

Cheers!
-Perry
