thank you for your quick reply. Don't take me wrong,
autotrace is a fantastic and powerful software! I am
actually very happy for being able to extract the central
lines at all. I truly appreciate your effort for writing and
sharing it with others!
Because I did not find detailed descriptions on some
of the flags, for example, "width-weight-factor", so, I
am not sure if I used autotrace correctly.
In your opinion, did I use the proper flags to do
the tracing for this particular image?

I used autotrace to extract the centerlines from a tubular
pattern. I found the resulting centerlines often has a
"seagull-wing" shape at a joint. To illustrate this, here
is the sample image that I want to trace:
the zipped bmp source file is at http://wenq.org/upload/test.bmp.gz
I used the following command:
autotrace -centerline -width-weight-factor 0.01 \
-remove-adjacent-corners -corner-threshold 60 \
-line-threshold 1.5 -filter-iterations 5 \
-output-format test.bmp -output-file test.svg
the output svg looks like this:
(the actual svg file is http://wenq.org/upload/test.svg)
Notice the "wiggly" pattern at the joints.
My question is: is there an optimized setting in
autotrace so that I can make these joints more
thanks a lot
