Making a screenshot

SDL Development

Hi, anybody know how to make a screenshot of the current backbuffer
surface? Maybe integrating it with Klipper or making a bitmap file of it?
Thanks alot in advance.

Fare thee well,

It is as simple as calling:

SDL_SaveBMP( pSurface,“FILE.BMP” );

The pSurface is a pointer to a SDL_Surface and the string is the filename to
save it as.

Yes. And for OpenGL, call glReadPixels() to get the contents of the
OpenGL framebuffer…then you’d need to get the raw pixel data into some
format you can use (like a SDL_Surface for SDL_SaveBMP, etc).

Ah, I see thanks guys. Although my first impression about screenshot would
be copying the surface to a clipboard daemon (eg. Klipper, or Windows’
Clipboard). But because I don’t understand Linux that much, making a
bitmap file of the surface will be suffice right now. Maybe I’ll explore
more on how to copy the surface’s contents to KDE’s Klipper when I have
time. Thanks alot guys.
