Hello:

If you are just looking for a utility that converts
FITS files pixel depths, you might be interested
in the following stand-alone C code:

http://www.eso.org/~ndevilla/saft

Go to the bottom of the page and have a look at
'iofits'. It does pixel depth conversion between
all possible FITS types. Beware that no scaling
is applied, though.

'iofits' is stand-alone, i.e. you do not need any
special library or compiler nor external programs
to compile and use it. Just do:

gcc -o iofits iofits.c

... and you're done.

Hope it helps,
