How to use getframe without displaying the figure?

Hi,

I am trying to use getframe without displaying the figure. I have read it is impossible because getframe needs the figure to be displayed. So the following code does not work:

figure('visible', 'off')

Do you have any idea how to do that? At least prevent the figure from popping up and display it "behind" the Matlab main window?

Hi,

I tried the following in MATLAB R2015b and R2016a and this worked fine where getframe was able to capture the figure without popping up the figure window.

f = figure('visible', 'off');
plot(rand(5))
F = getframe(gca);

Further to display the captured figure, see below:

figure;
imshow(F.cdata)

Can you share the reproduction code and the version of MATLAB you are working on?

Hi, it works fine. But I noticed it takes 4 TIMES longer when you DON'T VISUALIZE the output. Weird.
