I disagree, it is not a good tutorial unless you know what you are doing
with pixmaps, and Xwindows. It is very basic, and does not cover any
real information on drawing in X windows.

A good tutorial would start off by giving the different options for
drawing graphics to the screen, and which option to choose for which
application (one off drawing, animations, dynamic pixel graphics ...)
The tutorial would then go on and give examples of how to do them,
different options and everything.

I would love to write this tutorial, but I myself am still learning and
therefore can't

Thanks for the help (no sarcasm there), but either I am looking in the
wrong place or this gdkRGB has no documentation. It seems that it
doesn't provide what I need anyway, because for every image (where the
word image is used in the generic sense) I have (Which, incidentally is
connected to one top level window and drawing_area) it needs to be
32bit, and have it's only color map associated with it.

I am disparing at the lack of any good documentation in the GTK/GDK
project. I wish I could help, but I don't have enough of
conceptual/detailed knowledge at the moment. The Allegro library has it
right. That is excellent docs, the best I have ever seen.

Sadly wishing for the simpler days of dos/DJGPP/Allegro,
