  • The h4toh5 Library (alpha release)
  • HDF5 High Level APIs (beta release)

  • The h4toh5 Library (alpha release)

    An alpha version of the h4toh5 library is now available.

    The h4toh5 library consists of a utility (h4toh5) for converting a whole HDF 4 file into an equivalent HDF5 file, as well as a set of C library routines that perform part or all of this conversion when called from a C program.

    The software can be obtained from:

       ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/h4toh5/h4toh5lib1.0alpha.tar
    
    The HDF4 to HDF5 Library home page is located at:

    A User's Guide and Reference Manual can be obtained from this page.

    HDF5 High Level APIs (beta release)

    A beta version of the HDF5 High Level APIs is available from:
       http://hdf.ncsa.uiuc.edu/HDF5/hdf5_hl/
    
    The HDF5 High Level APIs consist of higher-level functions which do more operations per call than the basic HDF5 interface. The purpose is to simplify and standardize operations within HDF5.

    There are currently two APIs:

    HDF5 Lite (HDF5LT):
    Consists of general higher level functions which do more operations per call than the basic HDF5 interface. This version of the API has two sets of functions - dataset and attribute related functions.

    HDF5 Image API (HDF5IM):
    Defines a standard storage for HDF5 datasets that are intended to be interpreted as images. The specification for this API is presented in another document, HDF5 Image and Palette Specification. This version of the API is primarily concerned with two dimensional raster data similar to HDF4 Raster Images. The HDF5 Image API uses the HDF5 Lite functions.
