[mapserver-users] Transposing/Duplicating Color Channels in a WMS Raster.

[W. Ryan Nestor]

Hello all,
	I am accessing the NED_1/3 wms server for a project.  I am wondering  
if there is a way to process the raster data within my mapfile in  
order to generate an alpha channel based on the contents of the single  
greyscale channel that is currently present.  I have tried generating  
a LUT, and applying it using "special processing directives".  I  
thought about classifying each level of grey using php, but there must  
be an easier way?
