[求助]判断文件格式时出错

<P>　　读入一个图像文件后，进行了文件格式的判断，结果出错，请大家帮我看看问题出在哪，谢谢！<BR>具体代码和出错信息如下：<BR>[FileName,PathName]=uigetfile(...<BR>{'*.bmp;*.jpg;*.tif;*.png','IMAGE Files (*.bmp,*.jpg,*.tif,*.png)';<BR>   '*.bmp','Bitmap (*.bmp)'; ...<BR>   '*.jpg','Joint Photographic Experts Group (*.jpg)'; ...<BR>   '*.tif','Tagged Image files (*.tif)'; ...<BR>   '*.png','Portable Network Graphics (*.png)'; ...<BR>   '*.*','All Files (*.*)'},...<BR>   'File Selector','')<BR>x1=imread(FileName);<BR>h_axes=axes('position',[0.04,0.35,0.45,0.40],'visible','on'); <BR>imshow(x1)<BR>info=imfinfo(FileName);<BR>if （info.ColorType=='truecolor'｜info.ColorType=='indexed'）<BR>　h1 = uicontrol(gcf, ... <BR>　'style','pushbutton',...<BR>　'Callback','changeformat', ... <BR>　'Position',[0.45 0.12 0.16 0.06], ... <BR>　'String','格式转换', ... <BR>　'Tag','Pushchange');<BR>end<BR>出错信息：<BR>???

<P>Error in ==&gt; open at 60<BR>if info.ColorType=='truecolor'</P>
<P>??? Error while evaluating uicontrol Callback.</P>

应该是uicontrol有问题，仔细看看帮助

happy教授，如果我把代码中的判断语句注释掉，就不提示出错。另外：<BR>??? Error using ==&gt; eq<BR>Array dimensions must match for binary array op.<BR>这是什么意思啊，我这段代码中并没用到eq啊，请教授指教，谢谢！

你试一下吧判断语句if （info.ColorType=='truecolor'｜info.ColorType=='indexed'）改成<BR>coltype=info.ColorType<BR>if（coltype=='truecolor'｜coltype=='indexed'）看看

<P>教授，我试了，还是同样的错误。</P>
