Here is an example:
% load an image
load flujet
imagesc(X);
% set up the measuring tool
h = imdistline(gca);
api = iptgetapi(h);
api.setLabelVisible(false);
% pause -- you can move the edges of the segment and then press a key to continue
pause();
% get the distance
dist = api.getDistance();
% print the result
fprintf('The length of the segment is: %0.2f pixels \n', dist)

I never knew there was a built-in imdistline - I've always used improfile(). But anyway, in your own personal overridden version of imdistline - you know the one where for some reason you did not take Walter's advice to rename it - you're missing "function imdistline(handleToFigure)" as the first line of your m-file. Of course you know that must replace the word "handleToFigure" with whatever handle name you're using to refer to the figures with.

when I replace the load function with imread function, the image become rectangle and not in actual size. How to make it show in actual size?
