12、图片打开与保存
(1)前台界面
(2)添加打开图片的回调函数
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
[filename,pathname]=uigetfile({'*.jpg';'*.bmp';'*.gif'},'选择图片');
if isequal(filename,0)
disp('Users Selected Canceled');
else
str=[pathname filename];
im = imread(str);
axes(handles.axes1);%axes1是坐标轴的标示
imshow(im);
end;
（3）保存并退出的回调函数
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton2 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
[filename,pathname]=uiputfile({'*.bmp';},'保存图片','Undefined.bmp');

%saveas(gcf,str,'bmp');
ta = getappdata(gcf,'Timg');
imwrite(px.cdata,str,'bmp');
close(gcf);
else
disp('保存失败');
end;

% PIC_1, by itself, creates a new PIC_1 or raises the existing
% singleton*.
%
% H = PIC_1 returns the handle to a new PIC_1 or the handle to
% the existing singleton*.
%
% PIC_1('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in PIC_1.M with the given input arguments.

% PIC_1('Property','Value',...) creates a new PIC_1 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before pic_1_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop_music. All inputs are passed to pic_1_OpeningFcn via varargin.
