I need GUI Save As button for an image in a figure please.

Hi,

Is it possible to make a "Save As" button for an image that is showed in a figure? This is my button that generates the image :

function GenAnaglif_Callback(hObject, eventdata, handles)
% hObject    handle to GenAnaglif (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

global im_dr
global im_st
global im_final
im_final=contopire(im_st,im_dr, .5);
figure                 
imshow(im_final);

All i could come up with is this function with "imwrite" but this only saves a file with a default name in the application folder.I would really like the Save As button.

function Salveaza_Callback(hObject, eventdata, handles)
% hObject    handle to Salveaza (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

global im_final
imwrite(im_final,'imagine.jpg','jpg')

I'm not advanced with Matlab so please if you guys can be specific with your answer, it would be great.

Thank you very much.

You could have an edit box that has the the default file name but can be changed. Then when the save as button is called it saves with that.

%In saveas_callback(...)

fn = get(handles.edit_filename,'string');
imwrite(im_final,fn,'jpg');

Thank you !

Simple and efficient :D

FYI, you should "accept" the answer too so he gets credit. :)

You can modify sean de's suggestion by including a pushbutton next to the edit text and calling 'uigetfile' in the push button callback
