NAME

       SDL_WriteSurfacePixel - Writes a single pixel to a surface.

SYNOPSIS

       #include <SDL3/SDL_surface.h>

       bool SDL_WriteSurfacePixel(SDL_Surface *surface, int x, int y, Uint8 r, Uint8 g, Uint8 b, Uint8 a);

DESCRIPTION

       This  function prioritizes correctness over speed: it is suitable for unit tests, but is not intended for
       use in a game engine.

       Like SDL_MapRGBA, this uses the entire 0..255 range when converting color components from  pixel  formats
       with less than 8 bits per RGB component.

FUNCTION PARAMETERS

       surface
              the surface to write.

       x      the horizontal coordinate, 0 <= x < width.

       y      the vertical coordinate, 0 <= y < height.

       r      the red channel value, 0-255.

       g      the green channel value, 0-255.

       b      the blue channel value, 0-255.

       a      the alpha channel value, 0-255.
