Usage
#include "SDL3/SDL.h"
bool SDL_RenderTextureAffine(SDL_Renderer *renderer, SDL_Texture *texture, const SDL_FRect *srcrect, const SDL_FPoint *origin, const SDL_FPoint *right, const SDL_FPoint *down);
Header file
Defined in SDL3/SDL_render.h

the source texture.
- srcrect
-
a pointer to the source rectangle, or NULL for the entire texture.
- origin
-
a pointer to a point indicating where the top-left corner of srcrect should be mapped to, or NULL for the rendering target's origin.
- right
-
a pointer to a point indicating where the top-right corner of srcrect should be mapped to, or NULL for the rendering target's top-right corner.
- down
-
a pointer to a point indicating where the bottom-left corner of srcrect should be mapped to, or NULL for the rendering target's bottom-left corner.
Return value
