sdlWriteSurfacePixelFloat function

bool sdlWriteSurfacePixelFloat(Pointer<SdlSurface> surface, int x, int y, double r, double g, double b, double a,)

Writes a single pixel to a surface.

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

\param surface the surface to write. \param x the horizontal coordinate, 0 <= x < width. \param y the vertical coordinate, 0 <= y < height. \param r the red channel value, normally in the range 0-1. \param g the green channel value, normally in the range 0-1. \param b the blue channel value, normally in the range 0-1. \param a the alpha channel value, normally in the range 0-1. \returns true on success or false on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.1.3.
