You can implement the old functions in your own code easily:
```c
SDL_Surface *SDL_CreateRGBSurface(Uint32 flags, int width, int height, int depth, Uint32 Rmask, Uint32 Gmask, Uint32 Bmask, Uint32 Amask)
{
return SDL_CreateSurface(width, height,
SDL_MasksToPixelFormatEnum(depth, Rmask, Gmask, Bmask, Amask));
}
SDL_Surface *SDL_CreateRGBSurfaceWithFormat(Uint32 flags, int width, int height, int depth, Uint32 format)
{
return SDL_CreateSurface(width, height, format);
}
SDL_Surface * SDL_CreateRGBSurfaceWithFormatFrom(void *pixels, int width, int height, int depth, int pitch, Uint32 format)
{
return SDL_CreateSurfaceFrom(pixels, width, height, pitch, format);
}
SDL_Surface *SDL_CreateRGBSurface(Uint32 flags, int width, int height, int depth, Uint32 Rmask, Uint32 Gmask, Uint32 Bmask, Uint32 Amask)
{
return SDL_CreateRGBSurfaceWithFormat(flags, width, height, depth,
SDL_MasksToPixelFormatEnum(depth, Rmask, Gmask, Bmask, Amask));
}
SDL_Surface *SDL_CreateRGBSurfaceFrom(void *pixels, int width, int height, int depth, int pitch, Uint32 Rmask, Uint32 Gmask, Uint32 Bmask, Uint32 Amask)
{
return SDL_CreateRGBSurfaceWithFormatFrom(pixels, width, height, depth, pitch,
return SDL_CreateSurfaceFrom(pixels, width, height, pitch,
SDL_MasksToPixelFormatEnum(depth, Rmask, Gmask, Bmask, Amask));
}
SDL_Surface *SDL_CreateRGBSurfaceWithFormatFrom(void *pixels, int width, int height, int depth, int pitch, Uint32 format)
{
return SDL_CreateSurfaceFrom(pixels, width, height, pitch, format);
}
```
But if you're migrating your code which uses masks, you probably have a format in mind, possibly one of these:
