MATLAB: Adding image on gui without using image processing toolbox

Question

I want to add a .png / .jpg / .tif file on gui….without using imshow in image processing toolbox

CODE SEGMENT UNDER OPENING FUNC:

fig = handles.figure1;

axes(handles.axes1) [X,map] = imread('blkdiag.tif','tif'); IMG = ind2rgb(X,map); image(IMG);

ERROR MESSAGE:

Index exceeds matrix dimensions.

Error in ind2rgb (line 27) r = zeros(size(a)); r(:) = cm(a,1);

Error in dtc>dtc_OpeningFcn (line 62) IMG = ind2rgb(X,map);

Error in gui_mainfcn (line 221) feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});

Error in dtc (line 42) gui_mainfcn(gui_State, varargin{:});

Pls guide me on the standard way of doing this…also pls keep in mind that i don have image processing toolbox

Answer 1

Are you sure it's an indexed image? If so, what are the values of map? What size is it? Do this

whos X
whos map

Tell us what you see in the command window.
