Matlab更改figure上logo的方法.docx

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）。12.jpg (7.12 KB)2009-11-18 19:32更换过后的效果是：121.jpg (14.88 KB)2009-11-18 19:32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：function chgicon(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%College of Precision Instrument and Opto-Electronics Engineering,%Tianjin University, 300072, P.R.China.%Email: %$Revision: 1.0 $Date: 2005/12/2 $if nargin2error(MATLAB:chgicon,%s,Too many input arguments!);endnewIcon = 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 = figurechgicon(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)% eventdatareserved - to be defined in a future version of MATLAB% handles empty - handles not created until after all
