UNIX UTILITIES FOR IMAGE PROCESSING



TO SCAN TAPES:

The tapescan utility is usedto get the headers of tape files dumped. 
To use it, mount your tape on the tape drive corresponding to
the system you are on.  Make sure you push the "online" button.
Also, be sure you are no longer in the Skyflux program, by typing
in the word "unix".  Once you get the Unix operating system prompt,
(%) and your tape is ready, simply type in the word "tapescan".  This
will dump the headers of the tape files to your screen. You will
have to use the  'hold screen' button (which is a toggle) to stop
and re-start the scrolling so you can read the headers as they print.
The tape will automatically rewind when it reaches the double end of
file mark after the last image file.

To print the header dump, use the command "tapescan |lpr" which pipes
the output to the line printer.

To send the header dump to a disk file, use the command "tapescan > FNAME"
which creates the file you specify in the FNAME parameter.  You can
then browse or print the file at your convenience.  To browse the file,
use the command "view FNAME" where FNAME stands for the file name you
specified.  To print the file, use the command "FNAME |lpr" which 
pipes a copy of the file to the printer.  Be sure to delete the file
after you are sure you are done with it.
