People frequently want to grab images from the screen on the SGI.
For example, you may wish to put an image from Display or
register. The tool for doing this is called snapshot.
Please see the snapshot manual page (type man snapshot)
for an explanation of how to use snapshot.
The image file output by snapshot is in IRIS RGB format. This file may be read directly by Showcase, but needs to be converted before it will be read by PowerPoint. Use the topict program on the SGI to convert the RGB file to a Macintosh PICT file that will be read by PowerPoint.
