.SH "NAME"
|
|
SDL_VideoModeOK \- Check to see if a particular video mode is supported\&.
|
|
.SH "SYNOPSIS"
|
|
.PP
|
|
\fB#include "SDL\&.h"
|
|
.sp
|
|
\fBint \fBSDL_VideoModeOK\fP\fR(\fBint width, int height, int bpp, Uint32 flags\fR);
|
|
.SH "DESCRIPTION"
|
|
.PP
|
|
\fBSDL_VideoModeOK\fP returns \fB0\fR 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 \fIsurface\fR flags (see \fI\fBSDL_SetVideoMode\fP\fR)\&.
|
|
.PP
|
|
The bits-per-pixel value returned is only a suggested mode\&. You can usually request and bpp you want when \fIsetting\fR the video mode and SDL will emulate that color depth with a shadow video surface\&.
|
|
.PP
|
|
The arguments to \fBSDL_VideoModeOK\fP are the same ones you would pass to \fISDL_SetVideoMode\fR
