Copy surface to new surface

How can I copy a surface or a portion of a surface to a new surface?

Well, one thing you can do is blit from the original surface to a new
surface (SDL_BlitSurface: http://sdldoc.csn.ul.ie/sdlblitsurface.php )

If you want to duplicate a surface and convert its format to the display
format you can also use SDL_DisplayFormat:

SDL_BlitSurface(SDL_Surface *src, SDL_Rect *srcrect, SDL_Surface *dst,
SDL_Rect *dstrect)

is your friend :)–

Yeah, but I want to copy just a portion of a surface onto a new
surface with an alpha channel. When I use SDL_CreateRGBSurface()
and an amask of 0xff000000 the surface blits completely
transparent.
