Folks,
Well, it's been a quiet weekend in Paradise, my home town.
The kids were off studying. The wife was in Chicago
visiting her sisters. The weather was perfect for a
final walk in the high country, before the snow flies.
The only distraction was Coyote blaring his latest
Michele Shocked album at about 150 decibels from
his boom box. If I hear him sing "If love was a
train, I think I'd ride me a LONG one!" one more
time I think I will strangle him.
I planned to take a walk on one of my favorite
hiking trails to see what damage had been done
to it by the big fire this summer. There was just
this one burr under the saddle: as much as I liked
the new TRANSPARENT keyword to cgImage, I was annoyed
I couldn't get it to work either in PostScript or with
!P.MULTI.
I thought I would just take an hour to sort that
out, then I'd be off. But, you know how one thing
leads to another (and who was the idiot who wrote the
documentation for cgImage, anyway!), so about six hours
later, I finally had things working the way I wanted them
to work, and the sun was getting low in the sky, and ...
Oh, what the hell, this Coyote Library is driving me
crazy, too, so I'll just spend a couple of hours
sprucing that up.
The long and short of it is, the wife came home about
six hours before I expected her, the house was still
a mess, and and I had spent another 8-10 hours putting
things right with the Coyote Library. I added a couple
of useful features to some programs, retired a few more,
changed the name and documentation on a few others,
made sure all my web pages pointed to the new programs,
etc., etc.
Another whole day rolled by and I finished just in time
to run off to the end-of-year party the Wilderness Ranger
organization I belong to was having. The group of first year
volunteers I mentored won an award for most total patrols
by a first year group, and I won a $30 gift certificate
for Most Backpacking Patrols. Good thing they don't hand
out awards for Worst Weekend Husband or Longest Grass
Before Mowing, or I would have won those, too. You have
to be dedicated to go backpacking when the list of things
to do around the house takes up both sides of a sheet of
paper.
All this to say that now would be a good time to update
your Coyote Library. :-)

Or,
http://idl-coyote.googlecode.com/
Here are the things I remember doing, off the top of my head:
Beside getting the TRANSPARENT keyword to produce transparent
images everywhere and all the time, I added a Filename keyword
so you can read and display an image directly from a file. This
works spectacularly with GeoTiff images! (You know, I'm as
surprised and amazed at the power of Coyote Graphics
as I'm sure you are. These commands really do blow me away
sometimes!) I also added CTINDEX, BREWER, and REVERSE
keywords to cgColorBar, so you can load color table vectors
directly, as you do with cgImage. (Note, cgLoadCT, and XColors
work with the IDL-supplied Brewer color tables without my
having to do anything to them.)
I retired some really old programs that I haven't used in years,
transferring some to a new branch in the SNV repository called
CoyotePlus. These are mostly example programs I use in my IDL
programming classes. These are also available via my web page.
I'll have a link to them as soon as I make a final pass though
them to be sure there is no old library code lurking about.
I also retired and renamed the following programs:
FSC_Resize_Image -> cgResizeImage
PickColorName -> cgPickColorName
Color24 -> cgColor24
AddToPath -> cgAddToPath
FixPS -> cgFixPS
HasImageMagick ->cgHasImageMagick
XStretch -> cgStretch
I also updated all the Coyote Library documenation. Aware,
of course, of how the old, incorrect documentation will live
on for years in the new Documentation Center on the ExelisVis
web page. ;-)

I guess that's about it. I've got to go get ready for work. :-(
Cheers,
David
