[MapServer-users] How to define/declare often used color definitions is a "centralized" file

[Philippe Ghesquiere]

Hi Tanya,

A standard definition of symbol styling looks like :
STYLE
   SYMBOL 'cross'
   COLOR "#FF0000"
END

I would like to "centralized" my preferred color in order to declare
STYLE
   SYMBOL 'cross'
   COLOR "MyRedColor"
END

The discussion pointed out by Jukka (
https://www.mail-archive.com/mapserver-dev@lists.osgeo.org/msg00382.html.)
shows that the mechanism is not implemented.

Sincerely
Philippe
