[mapserver-users] Polygon border with marker line symbol

[Anton Bakker]

Hi Lars,

The fill of the square was set to true, but I guess that is what happens when you only set the OUTLINECOLOR and a SYMBOL on a polygon type style. 

In any case setting the type of the polygon layer to LINE did the trick. I was not aware this was possible, but it does make sense. Thanks for the quick answer!

Kind regards,
Anton

It seems the only way to set a picture line symbol on the border of a polygon is to only set the outlinecolor, but then there is no way to set the fill color for the marker. I could not find any any information about this in the documentation or the mailing list.
