Algorithm to 'walk' along a line from an endpoint by N pixels

[Jean-Patrick Pommier]

Hi,
This is not advertizing for my blog, but I faced the same kind of question 
here<http://dip4fish.blogspot.fr/2011/06/open-curve-to-ordered-pixels-second.html>. 
The idea would be first to convert the image of the curve into a set of 
ordered pixels, then counting pixels from that list is easy.
