It's a 32 bit float, a hightmap, and I need to convert it to a 16 bit float, so hopefully it's not as painful?
I'll take a look at ILM's half library when I get home, looks interesting, hopefully not too out of my league.
There are also C-language implementations of 16-bit 'Half' in GraphicsMagick and in littlecms (lcms). Both of these are offered under a liberal (MIT/X11) license.
OpenEXR is quite large and primarily written in C++ so using it just for Half support would be painful.
