* ``BGR;32`` (32-bit reversed true colour)
Premultiplied alpha is where the values for each other channel have been Premultiplied alpha is where the values for each other channel have been
multiplied by the alpha. For example, an RGBA pixel of ``(10, 20, 30, 127)`` multiplied by the alpha. For example, an RGBA pixel of ``(10, 20, 30, 127)``
