sdlGetMasksForPixelFormat function pixels

bool sdlGetMasksForPixelFormat(
  1. int format,
  2. Pointer<Int32> bpp,
  3. Pointer<Uint32> rmask,
  4. Pointer<Uint32> gmask,
  5. Pointer<Uint32> bmask,
  6. Pointer<Uint32> amask,
)

Convert one of the enumerated pixel formats to a bpp value and RGBA masks.

\param format one of the SDL_PixelFormat values. \param bpp a bits per pixel value; usually 15, 16, or 32. \param Rmask a pointer filled in with the red mask for the format. \param Gmask a pointer filled in with the green mask for the format. \param Bmask a pointer filled in with the blue mask for the format. \param Amask a pointer filled in with the alpha mask for the format. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety It is safe to call this function from any thread.

\since This function is available since SDL 3.2.0.
