You might find some more robust mouse-traps in the IDL Astronomy
library. idlastro.gsfc.nasa.gov

That is probably the key: Poly_2d allows one to give the size of the
output image as parameters, but ROT does not take advantage of this
option. I added an OUTDIM keyword to rot.pro that lets one pass the
output dimension to Poly_2d. My copy is at

ftp://idlastro.gsfc.nasa.gov/landsman/idl/rot.pro

I suppose a possible additional keyword to rot.pro would be to let it
compute itself the size needed to preserve all the data, and create an
output file with that size.

I think I mentioned Martin stopped in last weekend.
I've known Martin for years, but only through e-mail.
I gave him a book and he spent about five minutes
looking at me, then looking at my picture on the
back of the book, then at me again.

Finally, he said, "I don't think this picture
does you justice."

A nice complement, don't you think. :-)

Cheers,

David

P.S. Let's just say it's scary when you find your
father looking back at you from your mirror, but
when your grandfather starts showing up it is
*really* scary!

David, you were supposed to install Linux on the laptop, not upload it
directly to your own main CPU and fry it. "Matrix" time has not come yet
for RedHat :-)

Cheers,
Pavel

I think that btt be my evil twin! And my wife need only look at the end
of the leash. (To be fair - my wife is perfect just the ways she is...
she has one of this retractable leashes.)

Actually the btt came about because I renamed my 'Macintosh HD' to a
simpler name without spaces. My identify was lost in the bowels of some
preference file... well, next thing you know I had to start from
scratch. I have yet to figure out how to send mail (other than news.)
Like installing Linux I guess. Just how gray is your hair getting
anyway? Don't tell anyone, but I think I really hate computers.

Hmm, so it was a baseball reference. I didn't have a clue. Some
consider Mainers a wee-bit foreign from other Americans. (Note: not
'Maine-iacs', thank you very much, that name is reserved for the
top-flight pilots out of the Air National Guard in Bangor.)

Thanks,

Ben

I think this is the ol' Tinker-to-Evers-to-Chance
around the diamond problem. Your solution seems
as good as any.

My pleasure, but what is this "bbt" stuff? Is
your wife looking for you again. :-)

Cheers,

David

P.S. Let's just say I know its rude to our foreign
members to use baseball analogies, but this is the
only thing that comes to mind. I don't know why.
I think my brain is fried. :-(
