automatic tracing of outlines?

[Baggerly, ROY G]

I am interested in tracing a profile or outline in an image and creating
a simple x y data file. I believe Image Pro had a utility for doing that
and I was wondering if Image J has a similar capability with a plugin
somewhere? Thank you.

Use the Image>Adjust>Threshold tool to highlight the object of
interest, click on it with the wand tool to create a selection, then
save the X and Y coordinates using File>Save As>XY Coordinates.
