This release features a number of improvements for the X-ray tomography community with support for white and dark fields, initial support for using TomoPy in a Docker pipeline, and some additional color presets that were requested after we reworked our presets in the last release. We have made improvements under the hood too, with a more Pythonic interface for the operators to use (the old API was retained to support existing operators), and new API to support X-ray data.
A new crop operator was added which currently crops volume rendered data, it will be extended to support more visualization types in the future. The slice operator was improved to support “thick” slices, i.e. aggregation over multiple slices. We have improved the integration of the documentation within the application, offering more links from dialogs to the relevant help page/section. The documentation has been updated and improved to cover a wider array of use cases. We dropped support for Python 2 many years ago, and continue to support Python 3.7 at this point, with plans to move to Python 3.8 soon. The ParaView and VTK libraries were updated for this release, bringing in a number of fixes and improvements.
