SAOimage image display utility

SAOimage (pronounced S-A-0-image) displays astronomical images in the
X11 window environment. It was written by Mike Van Hilst at the Smithsonian
Astrophysical Observatory (SAO) in 1990 and is now maintained by Doug Mink,
also at the SAO.  Image files can be read directly, or image data may be
passed through a named pipe (Unix) or a mailbox (VMS) from IRAF display
tasks.  SAOimage provides a large selection of options for zooming, panning,
scaling, coloring, pixel readback, display blinking, and region specification.
User interactions are generally performed with the mouse, but keyboard
alternatives are often available.  World Coordinate System tracking is
available for FITS and IRAF .imh images.

The SAOimage desktop includes, a main image display window, a button menu
panel, a display magnifier, a pan and zoom reference image, and a color bar.
A color table graph window can be brought up by clicking on the color bar.

The current version of SAOimage is always available via anonymous ftp from
cfa-ftp.harvard.edu in the pub/gsc/SAOimage directory.
