Hello,
I am making an app on App designer and I need to be able to draw interactively a polygon on an image display on an axes.
I already tried imploy, roipoly and drawpolygon functions with 'app.UIAxes' as 'ax' parameter but none of them seem to be accepted by App designer.
Can someone help me ?
Thanks,
Anatole Jimenez

Here is the error for the following instruction :
function mask = drawplaque(app)
h2 = impoly(app.UIAxes);
mask = h2.createMask;
end
The error (quite long) :

For this draw polygon :
function mask = drawplaque(app)
h2 = drawpolygon(app.UIAxes);
end
This error :
Error using images.roi.internal.ROI/parseInputs
ROI parent must be a valid Axes object.
Error in images.roi.Polygon
Error in drawpolygon (line 155)
h = images.roi.Polygon(varargin{:});
Error in app2/drawplaque (line 84)
h2 = drawpolygon(app.UIAxes);
Error in app2/DrawnewplaqueButtonPushed (line 151)
mask = drawplaque(app);
Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 335)

Hello,
If you are using version R2018b or earlier then try mapping the current point of a UIFigure to the UIAxes.Should probably help.

Thank you for the answer Harshita Gupta.
I didn't quite understand, can you give an example for a UIFigure, 'fig1' and a UIAxes 'ax1' ?

Having the same problem here, version 2019b.

Hello Pietro,
Unfortunately I didn't find any solution at that time so I used an alternative.
I just open a new figure window when calling for a draw and repeat my figure on it.Then I use the function drawpolygon as it works on non-GUI figure.
