Folks,
I wanted to alert you to a couple of changes Wayne and I
made to AL_Legend today that will fix some of the problems
a few people have had using AL_Legend in the resizeable
graphics window, cgWindow.
The major change is how the WINDOW keyword is implemented.
Previously, each Coyote Graphics command was added to the
cgWindow individually. Now, the entire AL_Legend command
is added to cgWindow as a single command. This is more
in line with how other Coyote Graphics commands are written,
and solved a number of problems that have been reported to
us.
Also, some of you were having problems with the /CLEAR
keyword, especially if you were working in normal, black
IDL graphics windows. This has been fixed by a change
to cgColor, in which I have added the color "background".
This color is the opposite of the "opposite" color. :-)
Nevermind the details. The important thing is that
cgColor can now also determine and return to you
the background color of your graphics window. This is
used to good advantage in AL_Legend by allowing us to
"clear" the legend space in the background color and
avoid another reported problem.
If you haven't updated your Astronomy and Coyote libraries
in awhile, this would be a good time to do so. If you have
updated libraries already, then you will just need to
download the following two commands:

Cheers,
