SDL_RenderTextureRotated

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

Header File

Defined in <SDL3/SDL_render.h>

Syntax

bool SDL_RenderTextureRotated(SDL_Renderer *renderer, SDL_Texture *texture,
                         const SDL_FRect *srcrect, const SDL_FRect *dstrect,
                         double angle, const SDL_FPoint *center,
                         SDL_FlipMode flip);

Function Parameters

SDL_Renderer *	renderer	the renderer which should copy parts of a texture.
SDL_Texture *	texture	the source texture.
const SDL_FRect *	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.
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).
SDL_FlipMode	flip	an SDL_FlipMode value stating which flipping actions should be performed on the texture.

Return Value

(bool) Returns true on success or false on failure; call SDL_GetError() for more information.
