Reading raw data is easy enough, just use READU which will take in byte
streams. There are a couple of gotchas though. First up, you'll need
to know how the data is fomatted in terms of bytes per pixel and,
possibly significantly, whether multi-byte data points are big or little
endian.
Once you've got that sorted, just assign an array big enough for
everything in the relevant data type and then you can use REFORM to put
it into the size/shape you want.

That should be pretty easy with stuff like the iTools image profiler
and/or functions like MAX.
