function B = bound2im(b, M, N, x0, y0)
%BOUND2IM Converts a boundary to an image.
%   B = BOUND2IM(b) converts b, an np-by-2 or 2-by-np array
%   representing the integer coordinates of a boundary, into a binary
%   image with 1s in the locations defined by the coordinates in b
%   and 0s elsewhere. 
%
%   B = BOUND2IM(b, M, N) places the boundary approximately centered
%   in an M-by-N image. If any part of the boundary is outside the
%   M-by-N rectangle, an error is issued.  
%
%   B = BOUND2IM(b, M, N, X0, Y0) places the boundary in an image of
%   size M-by-N, with the topmost boundary point located at X0 and
%   the leftmost point located at Y0. If the shifted boundary is
%   outside the M-by-N rectangle, an error is issued. XO and X0 must
%   be positive integers.
