Ex employer wants google doc- can I send a screenshot

My ex employer has asked to be re-invited to some google docs I created on my personal account (they wold not get a work account). I know they have the right to the info, as I created it on company time- but can I send it to them as a screenshot? They were real assholes and they let me go after the work day ended and with no thought to handing over info/ closing out my duties. It is weeks later and now they want the documents. I would like to enjoy a little payback....
