A new release of Crayfish is now available from QGIS plugin repo.
Here are the new features in more detail…
We have added support for live trace animation on QGIS canvas:
Please note that export to trace animation (as an avi file) is not supported yet. To change vector style to traces, please refer to the Crayfish manual.
In addition to ASCII FLO-2D files, Crayfish can handle binary HDF output from FLO-2D. Several bugs related to FLO-2D file format were also resolved.
If you have any problem with Crayfish, please do not email us directly and consider filing a bug here: https://github.com/lutraconsulting/qgis-crayfish-plugin/issues
