Copy buffer of this to BUF.
The buffer is stored like this for each pixel: component0(plane0,plane1,plane2,...),component1(plane0,plane1,plane2,...),...
total size of BUF in bytes should be (bits_per_component * components + 7) / 8 i.e. rounding to the next multiple of 8 bits (only correct if 1 byte = 8 bits)
