[Mapserver-users] giff or png?

[Michael Schulz]

Hi,
if you want to use an image as a symbol, you have to define it in the 
symbolset file, sth. like:

SYMBOL
   NAME 'ushwy'
   TYPE pixmap
   IMAGE '/symbols/ushwy.png'
END

Then you can access this symbol in your layer via symbol number or 
symbol name. Change your layer defintion to:
...
  CLASS
     COLOR 255 255 255
     SYMBOL 'ushwy'
...

HTH, Michael
