NAME¶
SDL_VideoModeOK - Check to see if a particular video mode is supported.
SYNOPSIS¶
#include "SDL.h"
int SDL_VideoModeOK(
int width, int height, int bpp,
Uint32 flags);
DESCRIPTION¶
SDL_VideoModeOK returns
0 if the requested mode is not supported
under any bit depth, or returns the bits-per-pixel of the closest available
mode with the given width, height and requested
surface flags (see
SDL_SetVideoMode).
The bits-per-pixel value returned is only a suggested mode. You can usually
request and bpp you want when
setting the video mode and SDL will
emulate that color depth with a shadow video surface.
The arguments to
SDL_VideoModeOK are the same ones you would pass to
SDL_SetVideoMode
EXAMPLE¶
SDL_Surface *screen;
Uint32 bpp;
.
.
.
printf("Checking mode 640x480@16bpp.
");
bpp=SDL_VideoModeOK(640, 480, 16, SDL_HWSURFACE);
if(!bpp){
printf("Mode not available.
");
exit(-1);
}
printf("SDL Recommends 640x480@%dbpp.
", bpp);
screen=SDL_SetVideoMode(640, 480, bpp, SDL_HWSURFACE);
