Digitize2 has been placed in the Hobbes incoming directory.

  http://hobbes.nmsu.edu/pub/incoming/digitize2_01.zip 

It will later move to:

  http://hobbes.nmsu.edu/pub/os2/dev/rexx/digitize2_01.zip 

With Digitize2 the user can convert a line or other feature in a
raster image to a string of x,y points. The points may optionally
stored in an ASCII file. Digitize2 was designed to help convert old
graphs, figures, charts and other illustrations into a tabular
digital format. 

Digitize2 addresses three special problems inherent in this type of
work. First, it is rather easy to scan the printed material, but
getting it aligned accurately is a nuisance. Second, many scanners
and certainly most zerographic reproductions are not uniformly
scaled. Therefore, Digitize2 by default can correct for rotated
images and it does a linear correction for scale distortions.
Finally, Digitize2 allows the user to also edit the image. This will
be done automatically during digitizing or optionally using the
various paint tools available. This can greatly simplify keeping
track of progress when working on complex imagery.
