A frequent need is to work up a vector drawing from a pixel image. Most CAD or Bezier curve drawing programs will allow this by hand (for those that don't a work-around is to make the window transparent and place the image as a desktop background), and others will include auto-scanning functionality. There are special-purpose tools for this: http://vectormagic.com/home
