SDL 1.3: creating a 50% opaque black screen

SDL Development

Hi Folks

Is there a quick (and dirty) way to create a solid black screen with 50% opacity, to “grey out” whatever is on screen, without making such a graphic and loading it into memory?
I only use textures - no SDL surface.

Cheers
Ed

Try:
SDL_SetRenderDrawColor(0, 0, 0, 127);
SDL_RenderDrawRect(NULL);

But this will dim the screen rather than gray it. To gray it, use a shade of
gray instead of black.________________________________
