SDL_BlitSurface

Performs a fast blit from the source surface to the destination surface.

Header File

Defined in [SDL_surface.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_surface.h), but apps should _only_ `#include "SDL.h"`!

Syntax

#define SDL_BlitSurface SDL_UpperBlit

Return Value

Returns 0 if the blit is successful, otherwise it returns -1.

The blit function should not be called on a locked surface.

The blit semantics for surfaces with and without blending and colorkey are defined as follows:

Remarks

This assumes that the source and destination rectangles are the same size. If either \c srcrect or \c dstrect are NULL, the entire surface (\c src or

Code Examples

extern SDL_Surface *surface;
extern SDL_Rect source_rect;
SDL_Surface *temp_surface;
     
SDL_BlitSurface(surface, &source_rect, temp_surface, NULL);
