NAME

       SDL_GetWindowDisplayScale - Get the content display scale relative to a window's pixel size.

HEADER FILE

       Defined in SDL3/SDL_video.h

SYNOPSIS

       #include "SDL3/SDL.h"

       float SDL_GetWindowDisplayScale(SDL_Window *window);

DESCRIPTION

       This  is  a  combination  of  the window pixel density and the display content scale, and is the expected
       scale for displaying content in this window. For example, if a 3840x2160 window had a  display  scale  of
       2.0,  the  user  expects  the content to take twice as many pixels and be the same physical size as if it
       were being displayed in a 1920x1080 window with a display scale of 1.0.

       Conceptually this value corresponds to the scale display setting, and is updated  when  that  setting  is
       changed, or the window moves to a display with a different scale setting.

FUNCTION PARAMETERS

RETURN VALUE

       Returns the display scale, or 0.0f on failure; call

       SDL_GetError () for more information.

THREAD SAFETY

       This function should only be called on the main thread.
