Hello, Omid.You can grant permission "draw on whiteboard" for your users. See attachment. After this action users can draw on the board and can change size of uploaded document.
For more questions I think we need to use user mailing list: user@openmeetings.apache.org (About mailing lists you can see here: http://openmeetings.apache.org/mail-lists.html)
