getColorMod method

({int b, int g, int r})? getColorMod()

Get the additional color value multiplied into blit operations.

\param surface the SDL_Surface structure to query. \param r a pointer filled in with the current red color value. \param g a pointer filled in with the current green color value. \param b a pointer filled in with the current blue color value. \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.

Implementation

({int r, int g, int b})? getColorMod() => ffi.using((arena) {
  final rPointer = arena<Uint8>();
  final gPointer = arena<Uint8>();
  final bPointer = arena<Uint8>();

  if (!sdlGetSurfaceColorMod(this, rPointer, gPointer, bPointer)) {
    return null;
  }

  return (r: rPointer.value, g: gPointer.value, b: bPointer.value);
});
