RasterVect, the professional raster to vector conversion program (vectorizer).
The purpose of RasterVect is to quickly convert uneditable scanned paper drawings into accurate vector files for editing (as a CAD drawing) in any CAD program. It saves the converted file as one of vector formats: DXF, WMF, EMF, EPS or AI that can be read by any CAD program that supports these formats, including AutoCAD R14, 2000, LT and similar, like Corel Draw, Adobe Illustrator, Microstation, VectorWorks, TrueCAD, FastCAD and many others.
It's a direct replacement for traditional tracing and digitizing. It saves a lot of time. It is quicker than tracing with a digitizer.
