MATLAB: How can refer to rotational angle, which was made in another function of GUI

Question

Hi, I want to use obtained rotation angle for further computing in another function. Assignment of angle to handles.angle did not help.

———-

    handles.angle = round( get(hObject,'Value') ); 
    Im_r = imrotate(handles.pic, handles.angle, 'bilinear', 'crop');

———-

    angle=handles.angle;
    I_r = imrotate(I,angle, 'bilinear', 'crop');

Answer 1

The first code section looks like it should work fine, but you need to add

guidata( hObject, handles )

at the end of the function containing that code in order for your 'angle' field to be added to the GUI's 'handles' structure rather than going out of scope in a copy of 'handles' that is local to your first function.
