Hi
Is it possible to disable the distance label on the line created by imdistline? If the two end points are too close, then sometimes the label is on top of one of the end points...
Thanks,
Razvan

It's in the help, but not a real explicit example like my example for you below:
h = imdistline(gca);
api = iptgetapi(h);
api.setLabelVisible(false);

Hmm... for some reason it's not working for me...
I have in my code:
hDist1 = imdistline(hPlotAxes);
hDist2 = imdistline(hPlotAxes);
pause();
api1 = iptgetapi(hDist1);
api1.setLabelVisible(false);
api2 = iptgetapi(hDist2);
api2.setLabelVisible(false);
dist1 = api1.getDistance();
dist2 = api2.getDistance();
Am I doing something wrong here?

Nevermind... if I move the pause command after setLabelVisible, then it works.
Thanks

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)
