HDF is the National Center for Supercomputing Application's Hierarchical Data Format. It is extensible, machine-independent, tagged format used to store both images and scientific data. HDF is available via anonymous FTP from zaphod.ncsa.uiuc.edu (128.174.20.50) For more information on HDF, contact softdev@ncsa.uiuc.edu or Software Development - NCSA HDF 152 Computing Applications Bldg. 605 E. Springfield Ave. Champaign IL 61820 The utilities described below support conversion between HDF and the Sun Rasterfile or TIFF formats. Here is an excerpt from the README file of the distribution :: HDF Image Format Conversion Utilities by Jim Salem (salem@think.com) Thinking Machines Corporation This software is in the public domain. Please redistribute freely and keep this README file and author notices with the rest of the software. Contents :: hdf2tiff - converts HDF images to TIFF images tiff2hdf - converts TIFF images to HDF images hdf2ras - converts HDF images to Sun Rasterfile images ras2hdf - converts Sun Rasterfile images to HDF images ------------------------------------------------------------------------------ Formats: Rasterfile - Sun specific file format for 8 and 24 bit images HDF - NCSA 8 bit raster image format (used by ximage, xdataslice, etc.) - NCSA is the National Center for Supercomputing Applications TIFF - General purpose tagged image format (Aldus and Microsoft) ------------------------------------------------------------------------------ Compatibility :: These programs support HDF 8 bit raster images (i.e. those written using the DFR8 series of routines.) They have been tested on :: Sun 3 and Sun4 (OS4.0.3) VAX Ultrix 3.1 (TIFF conversion only) The HDF library version was 2.90. The TIFF library version was 2.2. Later versions and some earlier versions should work as well. ------------------------------------------------------------------------------ Availability :: This software is available via anonymous FTP from think.com (131.239.2.1). Transfer the file hdf_convert.shar.Z and use uncompress to restore the shar script hdf_convert.shar. Typing /bin/sh hdf_convert.shar will restore the files making up the conversion utilities. ------------------------------------------------------------------------------ Contact: Jim Salem Thinking Machines Corporation 245 First St. Cambridge MA 02154 (617) 876-1111 salem@think.com -- -- Jim Salem Thinking Machines Corporation, Cambridge, MA 617-876-1111 salem@think.com mit-eddie!think!salem, rutgers!think!salem, harvard!think!salem
