Writes a single pixel to a surface.
Defined in <SDL3/SDL_surface.h>
bool SDL_WriteSurfacePixelFloat(SDL_Surface *surface, int x, int y, float r, float g, float b, float a);| SDL_Surface * | surface | the surface to write. |
| int | x | the horizontal coordinate, 0 <= x < width. |
| int | y | the vertical coordinate, 0 <= y < height. |
| float | r | the red channel value, normally in the range 0-1. |
| float | g | the green channel value, normally in the range 0-1. |
| float | b | the blue channel value, normally in the range 0-1. |
| float | a | the alpha channel value, normally in the range 0-1. |
(bool) Returns true on success or false on failure; call SDL_GetError() for more information.
