Fixed bug #421 Comment #3 From esigra@gmail.com 2008-04-09 11:46:46 (-) [reply] ------- This bug also needs to be fixed for SDL_GetRGB and SDL_GetRGBA (those should not change the format of the surface either). Until this is fixed, I still need to const_cast the format parameter in calls to those functions.

.SH "NAME"
SDL_DisplayFormat \- Convert a surface to the display format
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBSDL_Surface *\fBSDL_DisplayFormat\fP\fR(\fBSDL_Surface *surface\fR);
.SH "DESCRIPTION"
.PP
This function takes a surface and copies it to a new surface of the pixel format and colors of the video framebuffer, suitable for fast blitting onto the display surface\&. It calls \fISDL_ConvertSurface\fR
.PP
If you want to take advantage of hardware colorkey or alpha blit acceleration, you should set the colorkey and alpha value before calling this function\&.
.PP
If you want an alpha channel, see \fISDL_DisplayFormatAlpha\fR\&.
.SH "RETURN VALUE"
.PP
If the conversion fails or runs out of memory, it returns \fBNULL\fR
.SH "SEE ALSO"
