sdlxWriteSurfacePixel function surface

bool sdlxWriteSurfacePixel(Pointer<SdlSurface> surface, SdlxPoint point, SdlxColor color)

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.

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.

\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, 0-255. \param g the green channel value, 0-255. \param b the blue channel value, 0-255. \param a the alpha channel value, 0-255. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function can be called on different threads with different surfaces.

\since This function is available since SDL 3.2.0.
