From: marwen on 11 May 2010 20:08 Actually this is what i did until now: function [] = GUI_1() clc S.fh = figure('units','pixels',... 'position',[300 300 300 300],... 'menubar','none',... 'numbertitle','off',... 'name','GUI_10',... 'resize','off'); S.ay = axes('units','pixels',... 'position',[20 50 160 140]); S.im = load('clown'); % This is a built-in ML example. colormap(S.im.map); % Set the figure's colormap. S.R = image(S.im.X); % Display the image on S.ax. set(S.ay,'xtick',[],'ytick',[]) % Get rid of ticks: avoid the scale of the image. S.pb = uicontrol('style','push',... 'units','pixels',... 'position',[10 10 180 30],... 'fontsize',14,... 'string','INVISIBLE/VISIBLE',... 'callback',{@pb_call,S}); var S.result; function [] = pb_call(varargin) % Callback for the pushbutton. S = varargin{3}; % Get the structure. [filename1,pathname1, filterindex] = uigetfile(... {'marwen(*.jpg,*.Rh)';... '*.m'},... 'Select the file you want to visualize','MultiSelect', 'on'); if isequal(filename1,0) disp('User selected Cancel') else S.result=fullfile(pathname1, filename1); S.im=imread(S.result); end But i don't know what to do after that ... Please help

Ex: After you read the image in the pushbutton callback: imshow(S.im); You might want to change more of this file, as I can easily tell that you ripped it off of Matt Fig's GUI_10. -Nathan
From: marwen on 12 May 2010 05:10 Yes that is true man,it isn't mine,i add just "how to load the file from windows"!! and it isn't this conversation what i am looking for. i don't know how can i call the axe in the declaration of the function and put the new image in it. So this is my problem right now. i think just there are two commands missing that is it. Please help i have less than 24h before sitting for the exaaam.
