		README File FOR scanSee.zip

This scanSee.zip file  contains the complete IDL files required for 
viewing the scanSee data saved by IOC on a WIN system. 

The save TIFF file will not work for true 24 bit color graphics.
The saved color scheme will work properly only if the 256 color
graphics is used in display setting.

In this example it assumes the following two directories are used
	D:\IDL\scanSee   - source directory where zip file is unzipped 
	D:\IDL\data      - data directory where scan files, config
                           files, and temporary files resides 

        For proper operation of scanSee package on WIN system, the
        following data sub-directories must be created for storing
	the temporary data files generated by the scanSee browsers.
	   ASCII\	- stores ascii data file
	   ROI\         - stores ROI files
	   TIFF\  	- stores TIFF files
	   CALIB\	- stores calibration factor files
	   XDR\		- stores XDR files

The startup file, working directory, and the search path must be
set accordingly.

IDLDE ENVIRONMENT SETUP
-----------------------

PROGRAM SEARCH PATH 
-------------------
Add the  D:\IDL\scanSee to the progrom search path

STARTUP FILE
------------
Following two files are IDL scripts provided for eazy startup of IDLDE
For running the realtime version use 'ezcaidl_startup.win' startup file.
For running without CA use the 'viewer_startup.win' startup file.

	D:\IDL\scanSee\ezcaidl_startup.pro           for realtime version
	D:\IDL\scanSee\viewer_startup.pro            for browser version

IDL SCRIPT
----------
Following four files allows the user for ezsy access of the IDL program 
as desired.

IDL> @go_DC                - start realtime scanSee at the IDL prompt (1D/2D/3D)
IDL> @go_SB                - start scan browser at the IDL prompt (1D/2D/3D)
IDL> @go_vw2d              - start vw2d at the IDL prompt (2D file only)
IDL> @go_pick3d            - start pick3d at the IDL prompt (3D file only)

WORKING DIRECTORY
-----------------
The working data directory should be separated from the IDL program
source directory. All the input scan files should reside in this 
directory.

Following configuration files can be created  under the data working
directory.

	DC.config       - created by go_DC
	scanSee.config  - created by go_SB 
	pick3d.config   - created by go_pick3d
	vw2d.config     - created by go_vw2d

Unfortunately the file name system is limited on W95, the
file name is shortened by the WIN system. And a user has
hard time to figure out the scan number from the shortened
name on the W95. A user has to check the time stamp, internal
scan number, external file name to figure out the sequence
number.

In case a user want to use the 'First', 'Next', 'Prev', 'Last' buttons 
in the IDL, the file names have to be converted to names consist of 
prefix, sequence number, and suffix '.scan' 

	prefix_xxxx.scan

where xxxx is the 4 digit sequence number used on the UNIX system.

If you dont want touch the file name, you have to always
use the File->Open to select the file.

SAVE TIFF FILE
--------------
For WIN system the vedeo display must be set to 256 colors
in order to get correct color schemes for the Tiff file saved,
