Screenshot of MATLAB Web App

Hi,

do you know a way to take a screenshot of a MATLAB Web App

The functions exportapp, exportgraphics, ... aren't supported in Web Apps.

While I can't answer your question - I'm looking for an alternative to exportapp as well, exportgraphics is actually supported in Webapps. You need to do it like

exportgraphics(axes, filename);
web(filename)

and then filename is getting downloaded in your browsers standard download path.

Hi,

Starting in Matlab r2020b, you can take snapshots of an app / uifigure using the functions below.

• exportapp
• getframe

Refer to the below article to get more info:

Hope it helps!!

exportapp is not supported in MATLAB Online™ or in Web Apps (MATLAB Compiler).

getframe does not support the following functionality in MATLAB Online™ or in Web Apps (MATLAB Compiler):

• Capturing the contents of a figure created with the uifigure function or any axes in the figure.
• Capturing the contents of an app created with App Designer or any axes in the app.

Exportapp is even mentioned in the question itself as not supported in Webapps.
