[mapserver-users] color range fade to transparent.

[Basques, Bob (CI-StPaul)]

All answering my own question . . .

I think this is working:

Set TRANSPARENT and the IMAGECOLOR in the MAP block:

TRANSPARENT true
IMAGECOLOR 254 254 254

 . . . then, set the COLORRNGE accordingly:

COLORRANGE 255 0 0 254 254 254  ## Red to Transparent
