1. With some off-line help from Ed Greshko, I got xv installed and 
working.  I thank Ed for his help.  I hope that the strong (super?) 
typhoon heading towards that area does not cause him and his family 
significant trouble.

2. I also tried the Gimp as per Matthew Miller's suggestion.  I found 
the functionality that I believe he's referring to.  The Gimp seems to 
insist on making the adjustment a curve rather than a straight line. 
I'll have to find and read the user's guide to see if those single 
channel manipulations can be made straight line segments.  The built-in 
help did not address that, at least not that I could see.  While the 
Gimp might not be able to do what I specifically want for weather 
satellite images, it sure looks useful and powerful for other kind of 
image and photo manipulation.  I thank Matthew for his help.
