This is TkPC / Version 0.02
(TkPC = Tk Private Colormaps)

Copyright (c) 1994 by Rainer Kliese
All rights reserved.
See the file COPYRIGHT for the copyright notes.

Restriction:
------------ 
Only Pseudocolormodells now!!
(Only 256 large colortables in the moment, will be changed soon)

Requirments:
------------
Tcl 7.3
Tk 3.6
TkPixmap (optional for demowish)
c compiler (required)
c++ compiler (required until you invest one day of work, to change m_color.new.cc back to C code)

Tested on:
----------
     SunOS 4.1.3 with gcc2.5.8
     Linux/Slackware 0.99pl15 with gcc2.5.8  

Description:
------------
Handle Colormaps with tcl
Give an easy mechanism to use those colortables in C and C++ function for drawing Pixmaps.

New wish interpreter: cwish
(  You find all new lines for TkPC for the new wish interpreter with: )
(  grep TkPC m_wish.c )

Two new wish commands:
---------------------
1.) Cmap
[Cmap list] : Gives a list of all by TkPC allocated colormaps
[Cmap query_tk]
[Cmap query_base map-name]
[Cmap query_work map-name] : This three functions return a define-list with the queried information
[Cmap alloc_work map-name name-of-list-variable] 
[Cmap store_work map-name name-of-list-variable]
[Cmap store_base map-name name-of-list-variable] : Look for this functions in the file Theory_OP
[Cmap free_work map-name]
[Cmap modeinfo] : returns a small list off all colormap and Visualtypes which are
                  supported by your X-Server
[Cmap create map-name type-name] : Create a colormap with arbitray name map-name of type type-name.
                                   type-name must be: default or private
[Cmap free map-name off max] : XFree all ColorCells in colormap map-name between index off and index max
                               Caution: wrong usage will terminate the interpreter without warning.
			       Problem: You must have allocate those ColorCells before you free them,
                                        which is in the moment only possible in the C or C++ code.
[Cmap connect widget cmap] : Connect a allready created widget with an existing colormap.
                             Attention: This widget must be a toplevel-widget and all its childs
                                        will be changed too!!
2.) DestroyCmap
[DestroyCmap cmap-name]: 
	Destroys a Colormap completly, and replaces it in all widgets which have used it with the default Colormap
 
This is only an alpha alpha!!! release of colormap handling under Tcl/Tk.
Nearby is a small demonstration program, which loads gif and xpm3 images and uses allways
a new private Colormap for this task.

I hope thinks will grow rappidly with TkPC, but are depending on how
much time I have between my normal work and on good new ideas
for a lot of unsolved problems.

Ideas and suggestions are always welcome.
