[Mapserver-users] adding RASTER Layer

[Dylan Keon]

Brock,

Syntax for OFFSITE changed in 4.0.  OFFSITE now takes an RGB value 
instead of a single class index value.  So, for example, if you're 
trying to make black pixels transparent you would now use "OFFSITE 0 0 
0" instead of "OFFSITE 0" (assuming class 0 was assigned to black pixels).

You could first try commenting out just the OFFSITE line to see if you 
get anything...
