Cannot insert image into MATLAB GUIDE
显示 更早的评论
I need to insert a small image into a GUI. Since using an axes (in this case tagged as axes2) seemed the likely option so I used one and added the following code into the OpeningFcn.
axes(handles.axes2)
matlabImage = imread('logo.tif');
image(matlabImage)
axis off
axis image
I am unfortunately getting the following error.
Error using image
Image CData must be an m-by-n-by-3 or m-by-n matrix.
Error in GUI_for_log>GUI_for_log_OpeningFcn (line 55)
image(matlabImage)
Error in gui_mainfcn (line 220)
feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure),
varargin{:});
Error in GUI_for_log (line 42)
gui_mainfcn(gui_State, varargin{:});
Is there some form of tweaking I need to do to the image before using it?

Are you sure the tif file contains an RGB image and not a different format? Some image formats are m-by-n-by-4.

In particular it might be RGBA

imfinfo the file.

Attach the image here with the paper clip icon.

You would use imfinfo() to find out whether the file is described as being RGBA. If it is then you would
image( matlabImage(:,:,1:3), 'AlphaData', im2double(matlabImage(:,:,:,4)) )
