As part of OfficeOne ProTools for PowerPoint, the Zoom feature allows you to zoom into slides during the slide show. The Zoom feature retains the quality of the slide when zooming into the slide.

Most of the objects on PowerPoint slides are vectors and get zoomed-in very well with high quality. These objects include Shapes, Text, Tables, Graphs/Charts, Diagrams, Cliparts, Smart art graphics, metafile images and others.

Many times, large images are inserted on PowerPoint slides and the images are then scaled down to get within the slide boundaries. Such images also zoom-in very well and their original size is considered while zooming in. The images are scaled appropriately using their original sizes.

The Zoom feature is available during slide shows through new menu items in the menu when you right-click on the slide show:

The new menu items are as follows:

1. Zoom In: Clicking the Zoom In menu item to zoom into the slide.
2. Zoom Out: The Zoom Out menu item does the reverse of zoom-in and zooms out a zoomed-in slide. It has no effect if the slide has not been zoomed-in.
3. Zoom Fit: The zoom fit menu item allows you to get back to the non-zoomed state of the slide.

When a slide is zoomed-in, its contents go off-screen and only a part of the slide is seen. This is where the Pan menu items come in. The Pan menu items allows you to sweep across the slide bringing in various parts of the slide into the view on the screen. The Pan menu items have no effect if the slide has not been zoomed-in.

These Pan menu items are as follows:

1. Pan Left: The Pan Left menu item allows you to move the zoomed-in slide to the left to show the contents to the right that have gone off-screen.
2. Pan Right: The Pan Right menu item allows you to move the zoomed-in slide to the right - it shows more content from the left of the slide and makes an equal amount of content go off-screen to the right.
3. Pan Up: This scrolls the zoomed-in slide upwards.
4. Pan Down: A reverse of Pan Up operation, the Pan Down menu item allows you to scroll the zoomed-in slide down.

Panning by right-clicking the slide to bring up the menu and then selecting the appropriate Pan menu item is, admittedly, a very clumsy way of sweeping across the slide. To make things better, you get Zoom & Pan Controls when you zoom into the slide. The Zoom & Pan Controls window looks like the following:

The Zoom and Pan buttons on this window work exactly like you use the Zoom and Pan menu items. You can click and hold down any of the Pan buttons to pan in that direction continuously until you reach the edge of that slide on the screen.

In multiple monitor setups, you can move the Zoom & Pan Controls window to another monitor and control the zooming/panning for the slide show that it running on a different monitor.
