% We implement readimage and sizeimage using the following 3 otherwise
% undocumented lower-level operators:
%
%	<x> <y> <width> <height> <matrix> .sizeimagebox
%	  <dev_x> <dev_y> <dev_width> <dev_height> <matrix>
%
%	- .sizeimageparams <bits/sample> <multiproc> <ncolors>
%
%	<device> <x> <y> <width> <max_height> <alpha?> <std_depth|null>
%	  <string> .getbitsrect <height> <substring>
%
% NOTE: These operators are subject to change without notice!

% Implement readimage using .getbitsrect.  Experimentation on a NeXT system
% shows that the data is always returned in order of increasing device Y,
% regardless of the CTM.
%
% Note that we can't make stack protection work for this operator,
% because it must remove its operands from the stack before calling
% the supplied procedure(s).
