                  Degas Elite Color Histogram Accessory
                             by Ken Newman


    If you've ever tried to analyze the usage of colors in an ST picture,
you will really appreciate this accessory. It only works from within
Degas Elite by Tom Hudson from Batteries Included/Electronic Arts(?).
It will work in either low or medium resolution, not in mono (it wouldn't
be real exciting in mono). DEGHISTO is in the public domain; it may be
freely distributed as long as it is not modified in any way and is
not sold.

    Basically DEGHISTO has two major features. It draws a little histogram
or bar graph in the current picture palette showing the precise relative
usage of pixel values in any of the available screen buffers of Degas.
At the bottom of the graph the percentage of pixels in each color is
shown. Unused pixel values are blanked out. This is useful enough, but
the other major feature is really neat. By pressing either mouse button
over one of the slots in the bar graph and holding it down, the display
flips to the screen chosen in DEGHISTO's screen field, with only pixels
of the color you chose displayed! All other colors in the palette are
temporarily set to black (the actual Degas palette is not changed).
With this you can see where in a picture each single color is used.
An even niftier variation on this is that if you hold down the ALT
key *before* you press and hold a mouse button, the display switches to
the picture you selected with that color CYCLING through related colors!
The other colors in the palette remain unchanged so you can see where
that color is used in relation to the rest of the picture. Try it, you'll
see what I mean.

How did you ever get by without DEGHISTO? Enjoy!
