imdistline

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);

Thanks!

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

[norfaizayu]

can you give me the example of imdistline?i cannot get it how it function.

[Razvan]

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)
