sdlxGetDefaultTextureScaleMode function render

int? sdlxGetDefaultTextureScaleMode(Pointer<SdlRenderer> renderer)

Get default texture scale mode of the given renderer.

\param renderer the renderer to get data from. \param scale_mode a SDL_ScaleMode filled with current default scale mode. See SDL_SetDefaultTextureScaleMode() for the meaning of the value. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.4.0.
