How can showing gif image during matlab processing
Mostrar comentarios más antiguos
I am developing a code to show a gif image during matlab processing. When the process is finished, the gif image is closed and the result would be plotted. However, the gif image is stopped when the matlab processing is being processed.
gif_image='C:\Users\Amir\Desktop\spinner.gif';
[handles.im,handles.map] = imread(gif_image,'frames','all');
handles.len = size(handles.im,4); % number of frames in the gif image
delay_length = 0.2;
axes(handles.axes1)
hold(handles.axes1,'on');
imshow(handles.im(:,:,:,1),handles.map);
handles.count = 1;% intialise counter to update the next frame
handles.guifig = hObject;
handles.tmr = timer('TimerFcn', {@TmrFcn,handles.guifig},'BusyMode','Queue',...
'ExecutionMode','FixedRate','Period',delay_length); %form a Timer Object
guidata(handles.guifig, handles);
start(handles.tmr); %starts Timer
% Update handles structure
guidata(hObject, handles);
when this part is going to begin, showing the gif image is stoped. :(
try
[matlabImage mask1 col col1 x y boundaries]=read_img();

What is the contents of TmrFcn()? Is this still executed during the computations? If not, this would be a better description: "The timer callback is not executed during processing".

On the undocumented site you can find a method to hide the border of a button, such that it should look like the image appears in the axes.
Matlab's axes object is not thought for displaying animated GIFs. You can emulate this by a timer callback, but you have seen the limitations already. So why do you want to display the animated GIF in an axes?
By the way: You did not answer my question, if the timer callback is triggered at all. It would be useful to know this, because perhaps it contains a bug only.

I mean that axes objects are not suitable for animated GIF files.
