Copy a portion of the source texture to the current rendering target, with rotation and flipping, at subpixel precision.


int SDL_RenderCopyExF(SDL_Renderer * renderer,
                    SDL_Texture * texture,
                    const SDL_Rect * srcrect,
                    const SDL_FRect * dstrect,
                    const double angle,
                    const SDL_FPoint *center,
                    const SDL_RendererFlip flip);

Function Parameters

renderer The renderer which should copy parts of a texture.
texture The source texture.
srcrect A pointer to the source rectangle, or NULL for the entire texture.
dstrect A pointer to the destination rectangle, or NULL for the entire rendering target.
angle An angle in degrees that indicates the rotation that will be applied to dstrect, rotating it in a clockwise direction
center A pointer to a point indicating the point around which dstrect will be rotated (if NULL, rotation will be done around dstrect.w/2, dstrect.h/2).
flip An SDL_RendererFlip value stating which flipping actions should be performed on the texture

Return Value

Return 0 on success, or -1 on error


This function is available since SDL 2.0.10.
