 Just stumbled upon it by accident.

 The constructor "packed_pixel(int chan0, int chan1, int chan2, int chan3)"
 assigns "at_c<2>(*this)=chan3;" (overwriting the previous value of
 at_c<2>). This should be "at_c<3>(*this)=chan3;"

 Similar problem exists in the constructor "packed_pixel(int chan0, int
 chan1, int chan2, int chan3, int chan4)" where "chan3" and "chan4" are
 assigned incorrectly.

 I have not included a patch, since fixing the problem is straight forward.
