Hi everyone :)
Is it possible to export a part of a matlab app as an image? I was working with exportapp(app.UIFigure, app.EditField.Value) wich worked fine to export the whole app, but I want to export only parts of it... Is there an easy way?

You can try
Img = getframe(app.UIFigure)
Img = Img.cdata
imwrite(Img,'filename.png')
or
Img = getframe(app.UIAxes)
Img = Img.cdata
imwrite(Img,'filename.png')
If you want a segment of image, you can specific it based on pixels:
imwrite(Img(1:50,end-50:end,:),'filename.png')
