[mapserver-users] Rendering line crossing iteslf

[thomas bonfort]

An undocumented and "not guaranteed to work in future versions" is to
trick mapserver in not drawing the cached base style for bridge lines.
As you are avoiding the line caching mechanism, you have to tweak the
linecaps for the base style.

CLASS
   EXPRESSION ([bridge]=1)
   STYLE
   END
   STYLE
      color black
      width 5
      linecap butt
   END
   STYLE
      color yellow
      width 3
      linecap round
   END
   STYLE
      color black
      width 1
   END
END

I haven't tested this recently, so please keep in touch if this solves
your problem or not.

regards,
thomas
