Coloring 32bit floating point rasters

[Samuel Hiatt]

Hi all!

I am trying to serve up several floating point 32-bit rasters and I am
curious to know the best way to render these images in color.  I've read
that it is possible to use a LUT to define the colors of a pseudo-color
image, but only for byte data (256 colors).

Has anyone already tackled this problem of displaying these float32
rasters?  What do y'all think is the best way to do it?

Thanks!
Sam
