render fonts and get back the image by pixels

[Berci Norbert <nicolas hal2000 terra vein hu>]

Hi !

I have already sent a letter to this list, but unfortunately I have not
received any replies to it. :( I thought this list is a forum of non trivial
questions and the people who knows the answer. If my question is RTFM, or
so beginner, tell me. But getting no answer is a very bad thing.

So please tell me which widget and which function(s) I have to use for
the following:

1. I want to draw on the widget both colour pixels and colour primitives
   (lines, circles, etc.) by the gdk_draw_ series of functions.

2. I want render colour fonts on it (e.g. display text on it)

3. I want it displayed in the application's window, of course ;)

4. I want to get the whole image by RGB values (or by colormap indexes,
   but in this case I want to know the colormap index => RGB mappings,
   obviously) so I can save it in a file for post processing.

I hope this time I receive an answer.

Thank you in advance
