Sorry. Yesterday was a very busy day at work. I have never worked
with .arf files before. I ordered some panchromatic imagery from a
company called Sensiac. The data was all sent in movie files in
this .arf file format using a program called ImageJ made from NIH---
it's a free viewer comparable to IDL and ENVI apparently. Anyway, I'm
used to not having problems bringing in files into ENVI. Now I have to
do it via IDL and I'm not sure how to do it. Funny how you'd think
attending the IDL courses I'd know how to bring in a simple file into
ENVI after converting it in IDL, but they never taught that crap. I
guess they figure teaching things like addition and subtraction of
variables like 2+2 is more valuable than bringing in data.

I think that Duppy might provide a little more detail, but since this
is likely to be imagery (given the ENVI reference) then these two
links might help. Or at least they can reduce the universe of
possibilities by determining if ARF is related to FITS...

and you can verify that a file is FITS using...

I guess that xnview ARF might be something else...

Here's what you can try:
1- download and install xnview and see if it will read the .arf
files. Then convert them to something that can be read into IDL, e.g.
TIFF, JPG, PNG, etc.
2- download and install ImageJ and read the files back in, then save
as something IDL can read.
3- figure out the file format of the .arf files (perhaps by contacting
Sensiac?) and write your own parser.

Sorry, you thought these fell into that category. It's
just that after 20 some years of answering IDL questions
whenever I get one that I think "I don't have any IDEA
how to do that!", it is from an IDL newbie. I don't
know why that is, but it is almost always the case.
I always feel just about the opposite of arrogant
when that happens. :-)
Cheers,
David
