I am having a look at it, thanks but from reading the code over at
It kind of seems that it supports splines fitting internally but you cannot initialize it with splines.
The other thing is that SVG uses cubic or quadratic bezier curves and arcs...
So far, for my approach I am going to go rather simple to get started
Have a function to convert SVG paths (open or closed) into ROIs (Polygons or polylines).
Something that can interpret the types of commands from http://www.w3.org/TR/SVG/paths.html#PathDataCurveCommands into sampled ImageJ PolygonRois
Finally, the ROIs will inherit the stroke color of the SVG unless it's black, wherefore it will default to the stored preference color. Names will also be assigned if an ID tag exists.
I have seen lots of tools for converting B-Splines to Bezier Curves but not the other way, so for now I am going to leave that behind. The bezier curves will simply be sampled an arbitrary number of times.
Lastly, @ctrueden: is there something shipped with Fiji to parse XML files? Thanks for everyone's support!
