Hi, This week I finished the development of contour line extraction algorithm. It works fine now. I only need to do some minor tweaks. It runs in O(n*n) time but after buffers are working I'll write O(nlogn) version, which is more complicated (I actually need to rewrite only one function and not all of them). The previous week I realized that the issues I found earlier with parallel_line() are serious. I've found out how to fix the two bugs but the behavior of parallel_line() is still not well defined. I'm going to start a thread in order to clear things up (hopefully). However this problems don't stop me from continuing development of buffer generation because there I need to create parallel lines only to lines containing no loops. Next week I'll write this specialized routine and discuss the issues with general parallel lines.
