Matlab更改figure上logo的方法

Matlab更改figure上logo的方法

有会员朋友问我能不能修改matlab中figure左上角的logo图标，因此写了这个帖子。答案是肯定的。比如我用这个卡通头像来做新的logo（不用真人的，不侵犯人家肖像权）。

更换过后的效果是：

这样就能使用自己的QQ头像或者照片来作为自己作品的标志了。具体实现方法，其实十分简单，只需要一个函数chgicon.m 该函数用红色文字表示：

functionchgicon(h,filename) %CHGICON changes the figure icon.

%CHGICON(H,FILENAME) changes the icon of a figure to an image specified by %the string FILENAME, where H is a handle to the figure. If the file is not %in the current directory or in a directory in the MATLAB path,specify the %full pathname of the location on your system. If FILENAME is not a valid %image file name, the function just removes the previous icon of the figure. % %Example: %h = figure;

%chgicon(h,'newIcon.png'); % replace 'newIcon.png' with your image

% IMPORTANT NOTES:

%REPLACING THE MATLAB GUI ICON VIOLATES THE LICENSE AGREEMENT % OF MATLAB. DO NOT USE THIS FUNCTION COMMERCIALLY. %%Han Qun, Sept. 2005 %Copyright 2005-2006 Han Qun

error('MATLAB:chgicon','%s','Too few input arguments!'); end ifnargin>2

error('MATLAB:chgicon','%s','Too many input arguments!'); end

newIcon = javax.swing.ImageIcon(filename); javaFrame = get(h,'JavaFrame'); javaFrame.setFigureIcon(newIcon);

将上面的函数保存在自己要使用的路径下，再调用即可。 调用语句：

h = figure

chgicon(h,'12.jpg');

就可以了。

再推广到GUI上也是一样的，只要在Create Fcn中调用这个函数就可以了：

function figure1_CreateFcn(hObject, eventdata, handles) % hObject handle to figure1 (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB % handles empty - handles not created until after all CreateFcns called chgicon(hObject,'12.jpg');

结果也是很成功：
