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.

Unfortunately, "exportgraphics does not capture most UI components, such as buttons or sliders".

It would be helpful if the above table included rows for webapp-compatibility and -limitations (e.g., for getframe as mentioned in Adrian's comment below).

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.
