How can I save a UIaxes-figure in a Matlab-Web-App by button callback

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
