% This assumes the image that is uploaded has square pixels, and that
% the units per pixel is the same for all the images loaded. The units and
% number of units are specified, then a line is draw to the number of
% units. Typically the image loaded will be an image of a ruler or the
% undeformed sample with known dimensions.
