SDL_RenderCopyExF

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

Header File

Defined in SDL_render.h

Syntax

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

SDL_Renderer *	renderer	The renderer which should copy parts of a texture.
SDL_Texture *	texture	The source texture.
const SDL_Rect *	srcrect	A pointer to the source rectangle, or NULL for the entire texture.
const SDL_FRect *	dstrect	A pointer to the destination rectangle, or NULL for the entire rendering target.
const double	angle	An angle in degrees that indicates the rotation that will be applied to dstrect, rotating it in a clockwise direction.
const SDL_FPoint *	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).
const SDL_RendererFlip	flip	An SDL_RendererFlip value stating which flipping actions should be performed on the texture.

Return Value

(int) Return 0 on success, or -1 on error.

Version

This function is available since SDL 2.0.10.
