Hy,
I would like to save a figure shown in a UIaxes of a deployed Matlab Web Aplication as png/jpeg-File in the ctfroot-directory.
example at button callback
print(app.UIaxes,'-dpng',fullfile(ctfroot,'myImage.png'))
The functionality of multiwindow to opy object to a new figure is not supported and i don't know how to access the figure in UIaxes.
Any help is appreciated
Best regards
Thomas

Your link does not give any solution. There the question is related to a GUI craeted with AppDesigner. This question is about WebApp GUI. The solution given in your link does not work for WebApp GUIs.

You can use exportgraphics(obj,filename) to write a graphics object obj to filename on the web app server temporarily. Afterwards call web(fileName) to display and/or download the file in the browser.
MWE:
function PrintButtonPushed(app, event)
fileName = 'graphic.pdf';
% or query for filename:
% [fileName, ~] = uiputfile('*.pdf');
exportgraphics(app.UIAxes, fileName)
web(fileName)
end
