Save to file (.jpg or bmp)

How can I save openGL view to the file of .jpg or bmp. I used one Dialog box for OpenGL view.
Any ideas

use glReadPixels looped for the entire screen and then you can easily save it as a .bmp. You can use the jepeg libary to save jepegs. You could also use OpenIL (image libary)( ) which allows you to import and export almost all file types and is linked to OGL and so is nicely compatible. I think you would still have to use glReadPixels though. If you just want a screen shot press the Print Screen button (maybe also with Alt)- it should work.
