silx 0.5.0

Software library for X-Ray data analysis

The silx project aims at providing a collection of Python packages to support the development of data assessment, reduction and analysis applications at synchrotron radiation facilities. It aims at providing reading/writing different file formats, data reduction routines and a set of Qt widgets to browse and visualize data.

The current version provides :

• reading HDF5 file format (with support of SPEC file format)

• histogramming

• fitting

• 1D and 2D visualization using multiple backends (matplotlib or OpenGL)

• image plot widget with a set of associated tools (See changelog file).

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

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

• OpenGL-based widget to display 3D scalar field with isosurface and cutting plane.

• image alignement (sift - OpenCL implementation)
