[mapserver-users] Applying a hatch over a line layer

[Adrian Popa]

Hello Thomas,

Thank you for your reply. I tried your solution and it draws a dashed 
line paralel to my feature (on each side because the symbol is thicker). 
This is nice, but I was wondering if it's possible to draw the lines at 
an angle relative to my feature, thus created the "hatch" effect.

If this is not possible with a simple symbol - would it be possible with 
a graphical symbol (picture)? And if yes, should I expect a high 
performance penalty?

Thanks again,
Adrian
