silx-kit/silx: v0.7.0: 2018/03/01

Input/output:

• Priovides silx.io.url.DataUrl to parse supported links identifying group or dataset from files.
• silx.io.open now supports h5pyd and silx custom URLs.
• silx.io.get_data is provided to allow to reach a numpy array from silx.

OpenCL:

• Provides an API to share memory between OpenCL tasks within the same device.
• Provides CBF compression and decompression.
• Simple processing on images (normalization, histogram).
• Sift upgrade using memory sharing.

silx.sx:

• Added contour3d function for displaying 3D isosurfaces.
• Added points3d function for displaying 2D/3D scatter plots.
• Added ginput function for interactive input of points on 1D/2D plots.

Graphic user interface:

• Provides a file dialog to pick a dataset or a group from HDF5 files.
• Provides a file dialog to pick an image from HDF5 files or multiframes formats.
• The colormap dialog can now be used as non-modal.
• PlotWidget can save the displayed data as a new NXentry of a HDF5 file.
• PlotWidget exports displayed data as spec files using more digits.

• Added new OpenGL-based 3D visualization widgets:

  • Supports 3D scalar field view 2D/3D scatter plots and images.
  • Provides an object oriented API similar to that of the 1D/2D plot.
  • Features a tree of parameters to edit visualized item's properties (e.g., transforms, colormap...)
  • Provides interactive panning of cut and clip planes.

• Updates of ScalarFieldView widget:

  • Added support for a 3x3 transform matrix (to support non orthogonal axes)
  • Added support of an alternative interaction when ctrl is pressed (e.g., rotate by default and pan when ctrl/command key is pressed).
  • Added 2 sliders to control light direction in associated parameter tree view.

silx view:

• Uses a single colormap to show any datasets.
• The colormap dialog can stay opened while browsing the data.
• The application is associated with some file types to be used to load files on Debian.
• Provides a square amplitude display mode to visualize complex images.
• Browsing an NXentry can display a default NXdata.
• Added explanation when an NXdata is not displayable.
• NXdata visualization can now show multiple curves (see @auxiliary_signals).
• Supports older NXdata specification.

silx convert:

• Added handling of file series as a single multiframe
• Default behavior changes to avoid to add an extra group at the root, unless explicitly requested (see --add-root-group).
• Writer uses now utf-8 text as default (NeXus specification).
• EDF files containing MCA data are now interpreted as spectrum.

Miscellaneous:

• Added silx.utils.testutils to share useful unittest functions with other projects.
• Python 2 on Mac OS X is no longer tested.
• Experimental support to PySide2.
• If fabio is used, a version >= 0.6 is mandatory.
