I have placed the final version of Digitize2 in Hobbes. In a little
while I will get the source code up there also.

  http://hobbes.nmsu.edu/pub/os2/apps/graphics/scan/Digitize3_20.zip 

It will eventually get to leo, when it comes up again. The program
now does everything I hoped to achieve when I started. If there is
something else that someone wants we will have to discuss it. Again,
I thank those who helped test it and gave feed back.  

This release incorporates smoothing and resampling based on
parametric bsplines. It also uses the SFX installer.  

Digitize2 lets you digitize and measure distances from an image using
your mouse. You can zoom in and pan around the expanded image. I use
it to convert old technical data published in journals to a digital
form as well as digitize maps. The output is ASCII. A DXF and IDRISI
export facility is also provided. 

Digitize2 addresses the 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 corrects for rotated images
and it does a linear correction for scale distortions. 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. Finally, you can move digitized
points, link to existing lines and generate smoothed lines using a
very powerful bspline algorithm.
