Subject: Software to get data from scanned graphics



Dear list members,

Frequently, I have to compare some data obtained in my research work with
the results given in published papers by the way of graphics, for example
the load-displacement path in a nonlinear analysis of a structure.

This requires the boring work of catching the data given in the graph of
the paper, in order to rebuild its curve. I've heard about a software which
automates this work, starting from scanned images of the graphics. Does
anybody know where I can get this software?

Thanks in advance
