[Mapserver-dev] polygon outlines with classified layers

[Bart van den Eijnden]

Hi developers,

I have switched to the mapserver-dev list, because it is too technical for 
the user list I guess.

If I have 2 classes in my LAYER, what determines whether or not the 
outline of a polygon is drawn? So I mean 1 class with outline color (class 
A), and another one without outlinecolor (class B). I see in my map that 
some parts of the border of class A adjacent to a class B polygon are 
drawn with an outline/border, and other parts are not. This can also be 
seen in this image which contains more than 2 classes:

Also is it possible, to only draw an outline when there is a 
border/transition between two classes? If I put on outline in all of my 
classes I have the problem that adjacent polygons which belong to the same 
class are drawn with an outline in between. In an ideal situation I would 
want only to have outline when there is a transition of classes.

Can anybody please comment on this subject? Is this kind of thing possible 
with Mapserver?

Thanks in advance.

Best regards,
Bart
