Once you've created a collage you like, you can review it in the AutoCollage View pane, and perform additional actions against it.
To zoom in and out, you can either use your mouse scroll wheel, or select the zoom control at the bottom left of the application and choose the desired zoom factor. Choices range from 12.5% to 800% zoom. There is also an 'Auto' choice which will fit the displayed AutoCollage to the size of the AutoCollage View pane.
If the AutoCollage is larger than the view pane, the scrollbars to the right and bottom of the view window become active. You can select the scroll bars to choose which part of the AutoCollage to view, or use the mouse to click on the collage and drag it until you can see the part you're interested in. Alternately you can select the AutoCollage View pane and use the arrow keys to pan.
The Actions pane in the upper right hand side of the application provides icons to perform the following additional actions with your AutoCollage:
