[mapserver-users] Re: Arrowhead in Mapserver 6.0

[Makoto Niwa]

me again,

It was resoleved.
I used negative value in vector symbol point such as -20,-10.
It was wrong. I thougt only -99 was non-continuous line value.
Use all postive value(except non-continuous value -99) in it,
I can get the same results by all 3 renderers.

thanks,

makoto.
