[mapserver-users] Draw points?

[Nacho Benito]

Hi Frank
Thank your for your help, It works now, I only have another little problem: 
I can draw a cross symbol but it's too small, and it always have the same 
size (and I zoom in it!)
What can I do?
In my map file I have:

SYMBOL
  NAME "cross"
  TYPE vector
  POINTS
    2 0
    2 50
    -99 -99
    0 25
    50 25
  END
END
Thank you again
regards
Nacho
