NAME

       SDL_SetRenderScale - Set the drawing scale for rendering on the current target.

HEADER FILE

       Defined in SDL3/SDL_render.h

SYNOPSIS

       #include "SDL3/SDL.h"

       bool SDL_SetRenderScale(SDL_Renderer *renderer, float scaleX, float scaleY);

DESCRIPTION

       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.

       Each render target has its own scale. This function sets the scale for the current render target.

FUNCTION PARAMETERS

       renderer
              the rendering context.

       scaleX the horizontal scaling factor.

       scaleY the vertical scaling factor.

RETURN VALUE

       Returns true on success or false on failure; call

       SDL_GetError () for more information.

THREAD SAFETY

       This function should only be called on the main thread.

AVAILABILITY

       This function is available since SDL 3.2.0.
