Can anyone point me toward some references for bit map compression schemes?  In
particular, I want to compress a 2^n x 2^n pixel image, each pixel with 2^m
grey levels, into less than 2^(2n) x 2^(m-1) bits.  (I really only need an
algorithm for m=1, but am interested in the more general case.)

Thanks!
