X11/XLib - Pixmap: Is there a way to access the pixel buffer directly?

Damián Gabriel Paz Adderly · 2004-07-19T01:13:23

I can't find the documentation of the XLib Pixmap structure. I've seen that people ussually uses a XImage to do double buffering in X. I want to use a Pixmap instead. Is it possible/recommended? EDIT: I want to access the pixmap buffer directly to plot pixel values myself. Thanks.

This page explains a bit. Maybe useful to you.

Thank you. I'm looking for a way to make a GUI independant of the window manager, so no matter which one you're running you'll be able to run the program.

I've some work done, but I find the drawing/color routines of Xlib to be too very much complicated and slow for what I want to do.

Cairo might be worth looking at.

It's still under a bit of development and interfaces will change by the time they make an official release, but not by much, me thinks.

Hmm. I don't think the wm should do any different. Did you mean GUI-tool kit independend?

I want to make it as much library independent as possible. If you are going to run it on X11 it will run in X11 without any 3rd party library (as GTK, Qt, etc).
If you are going to run it on windows, any clean installation of windows will run it. And so.

My goal is to bring a multiplatform game+installer_program with minimum dependencies.
