[mapserver-users] OFFSET and RAGECOLOR

[Ivan Ogasawara]

Sorry .. actually is OFFSITE

OFFSITE [r] [g] [b] | [hexadecimal string]

Sets the color index to treat as transparent for raster layers.

   -

   r, g and b shall be integers [0..255]. To specify black pixels, the
   following is used:

   OFFSITE 0 0 0


As in the mapfile sent.
