回答： Ely Raz 2017-6-2

In the following function, I send an image from my GUI axes to an imtool in order to do some manipulations. How can I transfer the manipulated image back to my GUI axes?

Script:

% --- Executes on button press in imtoolbutton.
function imtoolbutton_Callback(hObject, eventdata, handles)
% hObject    handle to imtoolbutton (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
J = getappdata(handles.imageAxes , 'yourVariable');
I=imtool(J);
axes(handles.imageAxes);
imshow(I);
setappdata(handles.imageAxes, 'yourVariable', I);

在 MATLAB Online 中打开

J = getappdata(handles.imageAxes , 'yourVariable');
h = imtool(J);

At this point you would want to give the user time to manipulate the image. Once they have done that,

ax = findobj(h,'tag','hImscrollpanelAxes');
I = ax.Children.CData;
imshow(I, 'Parent', handles.imageAxes);
setappdata(handles.imageAxes, 'yourVariable', I);
