[Mapserver-users] FW: WMS Client for ArcView 3.X

[kenboss]

ArcView 3.x is pretty much braindead when it comes to transparency in 
truecolor/24-bit/3-band images.  You can set a transparent color on a 
single-band colormapped image, but there is no such functionality corresponding 
to multi-band images, unless you want to shell out extra cash for ESRI's Image 
Analyst extension.
