title: Tracing a bezier curve from an image for a cocos2d game
body: <p>I was wondering if there is a tool that will allow me to construct/trace a closed bezier curve based on a background image?</p>
  
  <p>Basically I have a background image that represents some 2d curve which could be of some weird shape like a race track and I want to place some items along this path. </p>
  
  <p>I figured that if I can derive a quadratic bezier curve that will overlap the image I would be able to use the mathematical equations for this curve to compute individual points along its path..</p>
  
  <p>Does anyone know if such tool exists? Is my approach reasonable or totally off and there is a much simpler solution?</p>
  
  <p>Thank you in advance.</p>
