Quoting Juergen Bohnert <juergen.bohnert@uni-tuebingen.de>:
personally I think converting svg files to th2 files might be the best way of doing it. Since assigning distinct Therion features to imported svg lines is difficult, I feel that probably the best way is to import only a single feature at a time by breaking down svg files into separate items e.g. one file for walls one for stations etc. - that could be done in a fashion that reflects the later scrap structure. This is easily done if the original map had several layers.
Fine, I think writing Tcl script for this should not be a big issue, later it can be integrated into xtherion to support "File->Import" feature.
I do have several svg files that I would like to convert and I can send you some samples.
This would be great. Thanks, S.
