silx 1.0.0

The silx project aims to provide a collection of Python packages to support the development of data assessment, reduction and analysis at synchrotron radiation facilities. It intends to provide reading/writing tools for different file formats, data reduction routines and a set of Qt widgets to browse and visualise data. Silx can be cited by its DOIs referenced on Zenodo.

The current version (v1.0.0) caters for:

  • Supporting HDF5, SPEC and FabIO images file formats.

  • OpenCL-based data processing: image alignment (SIFT), image processing (median filter, histogram), filtered backprojection for tomography

  • Data reduction: histogramming, fitting, median filter

  • A set of Qt widgets, including:

    • 1D and 2D visualization widgets with a set of associated tools using multiple backends (matplotlib or OpenGL)

    • OpenGL-based widgets to visualize data in 3D (scalar field with isosurface and cut plane, scatter plot)

    • a unified browser for HDF5, SPEC and image file formats supporting inspection and visualization of n-dimensional datasets.

  • a set of applications:

    • a unified viewer (silx view filename) for HDF5, SPEC and image file formats


    • a unified converter to HDF5 format (silx convert filename)
