It happens to all of us. Someone sends us an old logo and asks us to update it, re-size it, create a print version, etc. and all they have is a JPG or a scanned image. That used to drive me crazy because I knew that I’d have to spend quite a bit of time tracing the image and cleaning it up, before I could create a clean vector image but no more.
Inkscape to the rescue! Inkscape is an open source scalable vector graphics editor with capabilities similar to Illustrator, CorelDraw, or Xara X, using the W3C standard Scalable Vector Graphics (SVG) file format.
