I have a nice little AVS animation which generates a bunch 
of 24 bit images, and I'd like to stuff these into a 8-bit
HDF file so that colleagues without AVS and 24-bit displays
could look at the animation with NCSA's ximage or xdataslice.

The problem: 
From the 24-bit animation images, I need corresponding 
8-bit animation images and a single 8-bit colormap.

One approach, which seems a bit brute force, is to save each
AVS image in a separate file, convert one of the frames to 8-bit 
using the PBM+ tool  

"ppmquant 256 avs.image.001 > cmap", 

then use that frame as a colormap for all the other frames

"ppmquant -map cmap avs.image.001 > ppm.image.001"

then finally convert the ppm images to hdf.

This all seems pretty crude.  I'm wondering if someone has a 
better idea?

Thanks,
