MATLAB: How to storage the coordinates of a pixel in Gui

axescoordinatesgui

In the Gui that I've created, the user should be able to click somewhere on the displaying image in an axes, and storage the coordinates of that pixel too use them later, but I don't know how should I 1. find the coordinates and 2. storage them for using them in another function later…

Best Answer

help ginput
That function will get the coordinates of the pixel the user clicks. You could have the user press a pushbutton to enable the pixel selection, then put your ginput call in the pushbutton callback.
Then, you can store these values by saving them to the handles structure:
[x,y] = ginput(N) %where N is the number of points desired
handles.X = x;
handles.Y = y;
guidata(handles.my_pushbutton,handles)
