If your goal is to not write any "null" pixels (e.g. black) from an

R,G,B values that are to be considered "null" and should not be rendered
into the output image. And there may be some more sophisticated
techniques
using the PROCESSING object in the layer definition.
so, i just tried that with the mapfile i showed you. i tried both
OFFSITE 255 255 255
and
OFFSITE 255
both result in totally blank output from mapserver for the request i posted?
thoughts?
thinking on this a bit more, i think what i need is a way to tell mapserver
a) which pixels to consider null
b) to use ALL coverages from my tileindex which cover the bbox NOT simply
the first
those two conditions should result in a dynamic mosaicing effect.
anyone done that?
