I am planning to write a book on using spreadsheet in business applications. May I use portion of LibreOffice Calc screenshots? I mean pictures which show for instance formulas in few cells, without showing the whole GUI?
I am asking because for instance Microsoft disallows doing that. According to their policies every screenshot should be full sized, with whole interface, etc. They only allow to resize the image – nothing else.
Thank you in advance for answering my question.
