Introduction — xtensor-io documentation (original) (raw)

Input/Output routines for reading images, audio, and NumPy npz files for the xtensor C++ multi-dimensional array library.

xtensor-io offers bindings to popular open source libraries for reading and writing

• Images with OpenImageIO (many supported formats, among others: jpg, png, gif, tiff, bmp …)
• Sound files with libsndfile (supports wav, ogg files)
• NumPy compressed file format (npz). Note: support for uncompressed NumPy files (npy) is available in core xtensor.
• Geospatial rasters with GDAL (many supported formats)
