pngphoon

Written by Sven Oliver Moll <svolli@svolli.de>

This program is intended as a successor to the great xphoon program (X PHase of mOON), which was written by Jef Poskanzer <jef@acme.com> and Craig Leres <leres@ee.lbl.gov> and is available from: http://www.acme.com/software/xphoon/

It uses some code from this program. For these fragments the following license applys:

The png file writing code was originally written by Guillaume Cottenceau <gc@mandrakesoft.com> and released under the terms of the GPL. (http://zarb.org/~gc/html/libpng.html)

For all other code (which was written by me) the GNU GPL applies which is provided as a separate file ('COPYING')

xphoon is a program that displays the actual phase of the moon on the X11 root window. Nowadays all desktop systems like KDE hide the X11 rootwindow with an own background image, so xphoon could paint as much in the root window as it likes to, but nothing was to been seen. KDE has an advanced interface for programs to dynamically provide background images in png format. That's what is program was originally written for.

Compiling: - necessary are only a C compiler and - the development files of the png library (png.h and libpng.so or .a) - a simple "make" should create the binary.

Setting up pngphoon for KDE:
- select configure desktop
- bring up the advanced options dialog
- check "Use the following program for drawing the background" - click add and fill out the form like this:
