###### (This is the legacy documentation for stable SDL2, the current stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current development version.) # SDL_LowerBlit Perform low-level surface blitting only. ## Header File Defined in [SDL_surface.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_surface.h) ## Syntax ```c int SDL_LowerBlit (SDL_Surface * src, SDL_Rect * srcrect, SDL_Surface * dst, SDL_Rect * dstrect); ``` ## Function Parameters | | | | --------------- | -------------------------------------------------------------------------------------------------------------- | | **src** | the [SDL_Surface](SDL_Surface) structure to be copied from | | **srcrect** | the [SDL_Rect](SDL_Rect) structure representing the rectangle to be copied, or NULL to copy the entire surface | | **dst** | the [SDL_Surface](SDL_Surface) structure that is the blit target | | **dstrect** | the [SDL_Rect](SDL_Rect) structure representing the rectangle that is copied into | ## Return Value Returns 0 on success or a negative error code on failure; call [SDL_GetError](SDL_GetError)() for more information. ## Remarks This is a semi-private blit function and it performs low-level surface blitting, assuming the input rectangles have already been clipped. Unless you know what you're doing, you should be using [SDL_BlitSurface](SDL_BlitSurface)() instead. ## Version This function is available since SDL 2.0.0. ## See Also * [SDL_BlitSurface](SDL_BlitSurface) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction)
