RE: Scan Pro for Windows
Many folks are already using one of the versions of WinTopo by SoftSoft Inc. It is a raster to Vector converter available for free at CNET or can be purchased. It has the ability to take colored lines and separate into layers. It will analyse linework, and connect into a polyline and exprt direct to Autocad of a lowgrade version of DXF. Even the freeware version is about the hottest conversion around. They have a couple user groups and forums on the internet to discuss recognition problems and software modifications.
