###### (This is the documentation for SDL3, which is the current stable version. [SDL2](https://wiki.libsdl.org/SDL2/) was the previous version!) # SDL_RenderTextureAffine Copy a portion of the source texture to the current rendering target, with affine transform, at subpixel precision. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_render.h) ## Syntax ```c 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); ``` ## Function Parameters | | | | | -------------------------------- | ------------ | --------------------------------------------------------------------------------------------------------------------------------------------------- | | [SDL_Renderer](SDL_Renderer) * | **renderer** | the renderer which should copy parts of a texture. | | [SDL_Texture](SDL_Texture) * | **texture** | the source texture. | | const [SDL_FRect](SDL_FRect) * | **srcrect** | a pointer to the source rectangle, or NULL for the entire texture. | | const [SDL_FPoint](SDL_FPoint) * | **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. | | const [SDL_FPoint](SDL_FPoint) * | **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. | | const [SDL_FPoint](SDL_FPoint) * | **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 (bool) Returns true on success or false on failure; call [SDL_GetError](SDL_GetError)() for more information. ## Thread Safety You may only call this function from the main thread. ## Version This function is available since SDL 3.2.0. ## See Also - [SDL_RenderTexture](SDL_RenderTexture) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryRender](CategoryRender)
