[mapserver-users] Vector symbol drawing problem

[Jez Walters]

Thomas,

I still don’t get any horizontal line drawn, even after setting the size and width as you recommended.  For what it’s worth, I’m not convinced that your size and width are what I want anyway, since a vertical line with these dimensions is drawn way too big – but thanks for the suggestion!

Warm regards,

Jez

In your examples you only set the width of the stroke for your symbol. What you want is size 10, width 1.
