# SDL_BlitSurfaceScaled Perform a scaled blit to a destination surface, which may be of a different format. ## Header File Defined in [<SDL3/SDL_surface.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_surface.h) ## Syntax ```c bool SDL_BlitSurfaceScaled(SDL_Surface *src, const SDL_Rect *srcrect, SDL_Surface *dst, const SDL_Rect *dstrect, SDL_ScaleMode scaleMode); ``` ## Function Parameters | | | | | ------------------------------ | ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------ | | [SDL_Surface](SDL_Surface) * | **src** | the [SDL_Surface](SDL_Surface) structure to be copied from. | | const [SDL_Rect](SDL_Rect) * | **srcrect** | the [SDL_Rect](SDL_Rect) structure representing the rectangle to be copied, or NULL to copy the entire surface. | | [SDL_Surface](SDL_Surface) * | **dst** | the [SDL_Surface](SDL_Surface) structure that is the blit target. | | const [SDL_Rect](SDL_Rect) * | **dstrect** | the [SDL_Rect](SDL_Rect) structure representing the target rectangle in the destination surface, or NULL to fill the entire destination surface. | | [SDL_ScaleMode](SDL_ScaleMode) | **scaleMode** | the [SDL_ScaleMode](SDL_ScaleMode) to be used. | ## Return Value (bool) Returns true on success or false on failure; call [SDL_GetError](SDL_GetError)() for more information. ## Thread Safety Only one thread should be using the `src` and `dst` surfaces at any given time. ## Version This function is available since SDL 3.2.0. ## See Also - [SDL_BlitSurface](SDL_BlitSurface) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategorySurface](CategorySurface)
