View Full Version : HELP Getting pixels color

Hey. Does somebody know how to get pixel color in OpenGl like getpixel in old Borland C++. I need it because i'd like to save image data. Maybe is there other way to do it ??? And second question - Is there in OpenGl possible to create two independent windows ???
It's very important for me . Thanks.

First, use glReadPixels.
Second, you don't create windows with OpenGL. You do it with the Win32 API (assuming you run Windows of course).

Forgot to answer the second question http://www.opengl.org/discussion_boards/ubb/smile.gif

Create the second window the same way you create the first window. Just make sure to activate the proper RC so you draw to the correct window.
