Whew! Busy day.

Since I last talked with you, I have been doing bug fixes
on the bug fixes, as well as making even more changes.
(You know how it is, you can put up with these niggling things
you want to change for just so long, then along comes an
amazingly productive day when you just say "the hell with it"
and you get everything done.)

So, a couple of things to be aware of, if you follow this
sort of thing:

My changes to XSTRETCH apparently introduced a bug that
I still haven't actually found, but believe to be there.
Thankfully, Peter Vontobel not only complained about it,
but supplied the right fix, too.

There was a small bug in FIND_BOUNDARY that crashed the
program when very small ROIs were used (on the order of
a couple of pixels). This appears to be fixed now.

I added a window resizing capability to the ANNOTATEWINDOW
program. I also added the ability to pass annotations to the
program on startup. This has required changes in Catalyst Library
routines, so I've put a new version of this program on my web
page as well.

My recommendation, if you use the Coyote Library, is to get a copy
of the entire library:

A note on the Catalyst Library. It is clear that I am not going
to have time to write the blockbuster best-seller Coyote's Guide to
the Catalyst Library, so I'm afraid that avenue for getting rich is
closing on me. So my current plan is to give this code away for
free, shortly after or coincident with a lecture I am giving at
the next IDL User's Group meeting in Boulder on October 16th.
That lecture will be about writing direct graphics objects,
and will expose the exceedingly simple ideas behind the Catalyst
Library.

I'm pretty convinced that my library, without any documentation
at all, will be easier for IDL programmers to use then the iTools
library with all the documentation in the world. :-)

Cheers,

David
