Viz Lab Scanner Introduction
----------------------------

To use the scanner, log on to the SGI named Natasha located in the 216 
laboratory.

The software is called: iopener
Here is a simple walkthrough of using iopener:

1. To execute the scanner type 
	iopener
   at the UNIX prompt.  A window will appear after a short amount
   of time labelled "iopener Scan Version 1.00".

2. At this time, place the material(s) you would like to have scanned
   in the scanner which is much like a photocopier in appearance.

3. Press the button called "Preview" near the bottom.  This will give
   you a full scan of the material(s) in the scanner.

4. Use the left mouse button in the preview window to drag open a
   cut window by holding the mouse down and moving the mouse.  This
   will create a rectangular region which will be used to make the 
   final scan.  You may resize or move this box by carefully pulling
   the edges or corners.

5. At this point you may want to change a few settings such as the
   scan resolution (higher the resolution, the larger the file size)
   or the format of the output image.  These options are in the window.

6. Press the "Scan" button when you are ready to scan the material(s).
   Another window will appear and ask you for a filename.  Modify the
   default filename if so desired and then press the "Scan" button on this
   window.  The scanner will begin it's final scan.

7. The scanned image is now saved automatically to disk.  You may exit
   now or scan some more material(s) (go to step 2 if so).
