I picked up the following Windows program a while ago, problem is I can't
remember which site it was on. Try an Archie search for DIGI138.zip. 




This program does the reverse job of a plotting program (Un-Graphing), it can 
import a scanned X,Y plot and digitize it to end up with a text file 
containing the X,Y points.

This program is distributed as an evaluation shareware version, if you use 
it for more than 30 days you should register, otherwise remove the program 
form your computer. A registered user will receive a user code that will 
make the program fully functional, and will also work with newer versions 
when they become available.

Limitation of the shareware version
The program is fully functional except the following:

* Only 10 digitized points are allowed.
* The Copy X,Y function is disabled.

This program is written in Visual Basic v2.0 which requires the VBRUN200.DLL
to be placed in you windows directory. the VBRUN200.DLL is available in many 
BBS sites and in ftp.cica.indiana.edu ( in the directory
/pub/pc/win3/util. (it might be still in the upload directory when you read 

1. Make sure VBRUN200.DLL is in your /windows directory.

2. Create a directory and copy all files to that directory.

3. You can now use the file manager to drag and drop the program icon into a 
   group in the program manager.

4. Select the program icon (in the program manager) by clicking on it once,
   select PROPERTIES from the FILE menu and make sure that the WORKING 
   points to the directory where you installed DIGITIZE.

** NOTE ** users of version 1.15 and higher, it is recommended that you 
delete your old DIGITIZE.INI before you start the new version otherwise it 
will contain unused settings.

The programs Digitize and WinFit are distributed as shareware. The cost 
(including shipping and handling) is the registration fee.
A registered user will receive a user code that will register the software,
This user code will work with all future shareware version of Digitize or WinFit.
As a registred user you will also receive a copy of the latest version 
(at the registration time ) on a disk.
