"""Pynche: The PYthon Natural Color and Hue Editor.
|
||
|
||
Pynche is based largely on a similar color editor I wrote years ago for the
|
||
Sunview window system. That editor was called ICE: the Interactive Color
|
||
Editor. I'd always wanted to port the editor to X but didn't feel like
|
||
hacking X and C code to do it. Fast forward many years, to where Python +
|
||
Tkinter + Pmw provides such a nice programming environment, with enough
|
||
power, that I finally buckled down and implemented it. I changed the name
|
||
because these days, too many other systems have the acronym `ICE'.
|
||
|
||
This program currently requires Python 1.5 with Tkinter. It also requires at
|
||
least Pmw 0.6.1. It has only been tested on Solaris 2.6. Feedback is greatly
|
||
appreciated. Send email to bwarsaw@python.org
|
||
|
||
Usage: %(PROGRAM)s [-c color] [-h]
|
||
|
||
Where:
|
||
--color color
|
||
-c color
|
||
initial color, as an X color name or #RRGGBB format
|
||
|
||
--help
|
||
-h
