Machines currently sup- - ported include the Cray, Convex, HP, Vax, Sun, IBM - RS/6000, Silicon Graphics, Macintosh, and IBM PC comput- - ers. HDF allows self-definitions of data content and easy - extensibility for future enhancements or compatibility - with other standard formats. HDF includes Fortran and C - calling interfaces,and utilities to prepare raw image of - data files or for use with other NCSA software. The HDF - library contains interfaces for storing and retrieving - compressed or uncompressed 8-bit and 24-bit raster images - with palettes, n-Dimensional scientific datasets and - binary tables. An interface is also included that allows - arbitray grouping of other HDF objects. - -WWW: http://hdf.ncsa.uiuc.edu/ +WWW: http://hdf.ncsa.uiuc.edu/HDF5/ |
