Summary
A prototype IRAF color image display package, COLOR, is now
available.
Currently this package provides conversion of 3 bandpass IRAF
images to a
Sun 24-bit RGB rasterfile format, a 24-bit to 8-bit compression
algorithm
and Floyd-Steinberg dithering, and an RGB 8-bit pixel dithering
algorithm.
The Sun rasterfiles are displayed using non-IRAF tools and the
others use
only IRAF images and SAOimage or IMTOOL. These tasks are usable
with the
currently common 8-bit color workstations and are provided for
those users
which don't have more capable hardware such as 24-bit workstations,
IIS
displays, and 24-bit addon cards. Addtional functionality will be
added to
the COLOR package in time.
The task RGBSUN takes three input IRAF images and produces a 24-bit
Sun
rasterfile. Though this file type was developed by Sun Microsystems
it is
a relatively simple format which may useful on other machines
having
software designed to use it. The color image may be displayed with
a variety
of non-IRAF tools such as XV (a very powerful and generic viewer
for
X-window systems), XLOADIMAGE (another X-window display tool),
SCREENLOAD
(a simple displayer on Sun computers), and SNAPSHOT (an Open-Look
tool).
Also some color printers can be used with this format such as a
Shinko
color printer.
