Raw

Release 5.4.0

  • Added explicit support for NumPy 2, in addition to NumPy 1.
  • Made image autorange and histogram more robust (#28).

Release 5.3.5

  • Fixed an issue where migrating older datasets to add a diffraction center automatically could fail (#26).

Release 5.3.4

  • Added new Bragg peak functionality of processed datasets, as well as arbitrary mask loading and generation for pre-processing.

Release 5.3.3

  • Fixed an issue when computing azimuthal averages (#18).

Release 5.3.2

  • Fixed some issues with new versions of Python and PyQt5 (#16) and other maintenance (#17).

Release 5.3.1

  • Fixed an issue where iris would use up all available memory for datasets with a large number of time-delays (>500)
  • Releases are now automatically performed using Github Actions

Release 5.3.0

5.2.5

  • Parallel operations on datasets (via HDF5 single-writer multiple-reader) is now possible on all platforms.
  • Code snippets in documentation are now tested for correctness.
  • Migration of test infrastructure to pytest.
  • Tests are now included in source distributions.

5.2.4

  • Added support for h5py 3.*.

5.2.3

  • Re-licensing iris-ued to GPLv3.
  • Changed the default colormap for processed datasets, to visually distinguish between raw and processed data viewers
  • Added support for Python 3.9

5.2.2

  • Fixed an issue where a broken plug-in would crash Iris. Instead, broken plug-ins will not be loaded.

5.2.1

  • Added the DiffractionDataset.time_series_selection method, which allows to create time-series integrated across an arbitrary momentum-space selection mask. This allows to create time-series from shapes that are not rectangular, at the expense of performance.
  • Added a few methods to create selection masks: DiffractionDataset.selection_rect, DiffractionDataset.selection_disk, and DiffractionDataset.selection_ring.
  • Added the ability to show/hide dataset control bar;
  • Added the ability to export time-series data in CSV format;
  • Fixed an issue where calculations of time-series, relative to pre-time-zero, would raise an error.
  • Symmetrization dialog is no longer in "beta".

5.2.0

  • Official support for Linux.
  • Plug-ins installed via the GUI can now be used right away. No restarts required.
  • Added the iris.plugins.load_plugin function to load plug-ins without installing them. Useful for testing.
  • Plug-ins can now have the display_name property which will be displayed in the GUI. This is optional and backwards-compatible.
  • Siwick Research Group-specific plugins were removed. They can be found here: https://github.com/Siwick-Research-Group/iris-ued-plugins
  • Switched to Azure Pipelines for continuous integration builds;
  • Added cursor information (position and image value) for processed data view;
  • Fixed an issue where very large relative differences in datasets would crash the GUI displays;
  • Fixed an issue where time-series fit would not display properly in fractional change mode;

5.1.3

  • Added logging support for the GUI component. Logs can be reached via the help menu
  • Added an update check. You can see whether an update is available via the help menu, as well as via the status bar.
  • Added the ability to view time-series dynamics in absolute units AND relative change.
  • Pinned dependency to scikit-ued, to prevent upgrade to scikit-ued 2.0 unless appropriate.
  • Pinned dependency to npstreams, to prevent upgrade to npstreams 2.0 unless appropriate.

5.1.2

  • Fixed an issue where the QDarkStyle internal imports were absolute.

5.1.1

  • Fixed an issue where data reduction would freeze when using more than one CPU;
  • Removed the auto-update mechanism. Update checks will run in the background only;
  • Fixed an issue where the in-progress indicator would freeze;
  • Moved tests outside of source repository;
  • Updated GUI stylesheet to QDarkStyle 2.6.6;

5.1.0

  • Added explicit support for Python 3.7;
  • Usability tweaks, for example more visible mask controls;
  • Added the ability to create standalone executables via PyInstaller;
  • Added the ability to create Windows installers;

5.0.5.1

  • Due to new forced image orientation, objects on screens were not properly registered (e.g. diffraction center finder).

5.0.5

  • Added the ability to fit exponentials to time-series;
  • Added region-of-interest text bounds for easier time-series exploration
  • Enforced PyQtGraph to use row-major image orientation
  • Datasets are now opened in read-only mode unless absolutely necessary. This should make it safer to handler multiple instances of iris at the same time.

5.0.4

  • Better plug-in handling and command-line interface.

5.0.3

The major change in this version is the ability to guess raw dataset formats using the iris.open_raw function. This allows the possibility to start the GUI and open a dataset at the same time.

5.0.2

The package now only has dependencies that can be installed through conda

5.0.1

This is a minor bug-fix release that also includes user interface niceties (e.g. link to online documentation) and user experience niceties (e.g. confirmation message if you forget pixel masks).

5.0.0

This new version includes a completely rewritten library and GUI front-end. Earlier datasets will need to be re-processed. New features:

  • Faster performance thanks to better data layout in HDF5;
  • Plug-in architecture for various raw data formats;
  • Faster performance thanks to npstreams package;
  • Easier to extend GUI skeleton;
  • Online documentation accessible from the GUI;
  • Continuous integration.
