Hello All, I have A 2D curve on paper. I want to interpolate the curve using Mathematica. I would scan it with a scanner, save the image to a file, convert the curve image into a set of Cartesian coordinates (4-5000 dots) and make Mathematica read this set to interpolate the curve (approximately). I know how to scan, but I don't know what kind of file I have to save the image to and how is it possible to convert the image to the set of Cartesian coordinates. (Once I have the coordinates, I think I know how to use the Mathematica "Fit" and "Interpolate" functions.) Thank you, Alvaro
