sdlRenderTextureAffine function render

bool sdlRenderTextureAffine(Pointer<SdlRenderer> renderer, Pointer<SdlTexture> texture, Pointer<SdlFRect> srcrect, Pointer<SdlFPoint> origin, Pointer<SdlFPoint> right, Pointer<SdlFPoint> down,)

Copy a portion of the source texture to the current rendering target, with affine transform, at subpixel precision.

\param renderer the renderer which should copy parts of a texture. \param texture the source texture. \param srcrect a pointer to the source rectangle, or NULL for the entire texture. \param 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. \param 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. \param 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. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety You may only call this function from the main thread.

\since This function is available since SDL 3.2.0.
