-.SH "NAME"
-SDL_DisplayFormatAlpha \- Convert a surface to the display format
-.SH "SYNOPSIS"
-.PP
-\fB#include "SDL\&.h"
-.sp
-\fBSDL_Surface *\fBSDL_DisplayFormatAlpha\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 plus an alpha channel, 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
-This function can be used to convert a colourkey to an alpha channel, if the \fBSDL_SRCCOLORKEY\fP flag is set on the surface\&. The generated surface will then be transparent (alpha=0) where the pixels match the colourkey, and opaque (alpha=255) elsewhere\&.
-.SH "RETURN VALUE"
-.PP
-If the conversion fails or runs out of memory, it returns \fBNULL\fR
