We are pleased to announce the release of the version 0.9.3 of the DGtal library and its DGtalTools (http://dgtal.org). This 0.9.3 release contains many improvements and  bugfixes, please have a  look to the complete changelog. We would like to focus on three new major features:
   - implementation of ParDirCollapse in cubical complexes ;
   - Volumetric analysis tools (VoronoiMap, PowerMap, —Reverse—DistanceTransformation and ReducedMedialAxis) now work on toroidal domains (with per-dimension periodicity specification) ;
   - a new version of the Vol format (Version 3) allowing compressed volumetric files (as efficient as PNG). You can convert your old Vol files to the new version using DGtalTools « convertVol » tool. Please note that older version are still supported in DGtal).
We would like to thank all contributors, issue reporters, documentation proof-readers and all the users for their feedback and help in this new release.
If you want to be in, just contact us ;)
