The jcolrgb Colour Selection Panel
The jcolrgb Colour Selection Panel
Introduction
The
jcolrgb application is just a wrapper around the
j:prompt_colour_rgb procedure in the
jprompts.tcl library. It's intended to make it easy to ask the user to
select a colour from shell scripts.
This document describes
jcolrgb version 4.1/4.2.
Copyright and contact information is available in
the
jstools documentation.

[-prompt
prompt]

Invoking
jcolrgb causes a panel to appear that lets the user select a colour
by RGB value using three sliders. A patch of the current colour
is displayed. When the user clicks OK, the current colour is
written to standard output. A label displaying

will be

Both
