Expand description

Set the drawing scale for rendering on the current target.

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.

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.

\param renderer a rendering context \param scaleX the horizontal scaling factor \param scaleY the vertical scaling factor \returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
