Function sdl2_sys::SDL_RenderSetScale

pub unsafe extern "C" fn SDL_RenderSetScale(
    renderer: *mut SDL_Renderer, 
    scaleX: f32, 
    scaleY: f32
) -> c_int

\brief Set the drawing scale for rendering on the current target.

\param renderer The renderer for which the drawing scale should be set. \param scaleX The horizontal scaling factor \param scaleY The vertical scaling factor

The drawing coordinates are scaled by the x/y scaling factors before they are used by the renderer. This allows resolution independent drawing with a single coordinate system.

\note If this results in scaling or subpixel drawing by the rendering backend, it will be handled using the appropriate quality hints. For best results use integer scaling factors.
