Hi physics.x2010, and welcome to the WordPress community!
I’m the developer of this plugin, however I’m not the developer of Google’s viewer, which my plugin embeds. Unfortunately there is no feature in Google Docs Viewer to do as you suggest at this time. Sorry to have bad news to report. While it may be possible with the Enhanced Viewer and some CSS hackery to get rid of the scrollbar, the preview size varies a bit by screen so it would be very difficult or maybe impossible to get exactly the experience you want.
It *is* possible to fetch just the page images themselves, and display them outside the standard viewer, to which another interface could potentially be designed. But that would be a pretty large undertaking. I will consider this for future versions if there is sufficient interest.
