The best way to convert paper drawings to digital images ?
pasbesoin: If you want vector graphics, my meager experience fwiw:Some months ago, I used potrace to convert drawings to SVG.  Specifically, on a Windows box, if I recall correctly, I used it via the front end Rasterbater (needs .NET 2).  I was quite satisfied with the result.This was for some simple black on white images.  The Wikipedia page for potrace (first link, below) has a bit of language about Inkscape being able to do a color decomposition.    > Inkscape is capable of producing color images by
    > decomposing each channel into several black and white
    > images and tracing them separately with Potrace.
