I tried following your simple example (I already had something similar)
but with no luck. I'm completely stumped as to why this doesn't work.
I even tried manually scaling the data to be in the range 0-255 out of
desperation. The data is definitely contiguous and 32 bit floating
point. At this p

The array would have to be cont

Also, does PIL have a contrast / scale option that is similar to zscale
in ds9 or equalize in Image Magick?

What arguments do you pass to this function, and do you flatten the
array from the FITs image? I this but got garbage out for the image.

I know and love PyFits, but I need to be able to do draw shapes on a
FITs image (and perhaps some other operations), and I don't believe
that PyFits allows these kinds of operations. It might be possible to
import the data into a numarray o

I'm trying to read in a FITs image file for my research, and I decided
that writing a file decoder for the Python imaging library would be the
easiest way to accomplish this for my needs. FITs is a raw data format
used in astronomy.
Anyway, I followed the example in the PIL documentation online,
