1In this directory there are hdf utility programs, makefiles, and a 2subdirectory, testfiles/, which contains all the data files needed to test 3the utilities. 4 5The utilities are: 6 7 . hdf24to8 -- converts 24-bit raster images to hdf 8-bit images 8 9 . hdfcomp -- re-compresses an 8-bit raster hdf file 10 11 . hdfls -- lists basic information about an hdf file 12 13 . hdfpack -- compacts an hdf file 14 15 . hdftopal -- extracts a palette from an hdf file 16 17 . hdftor8 -- extracts 8-bit raster images and palettes from an 18 hdf file 19 20 . hdfed -- hdf file editor 21 22 . hdfunpac - unpacks an HDF file by exporting the scientific 23 data elements (DFTAG_SD) to external object 24 elements. This is a utility for external file 25 handling for the parallel I/O interface on the CM5. 26 27 . paltohdf -- converts a raw palette to hdf 28 29 . r8tohdf -- converts 8-bit raster images to hdf 30 31 . ristosds -- converts a series of raster image hdf files into a 32 single 3D sds hdf file. 33 34 . vmake -- creates vsets 35 36 . vshow -- dumps out vsets in an hdf file 37 38 . jpeg2hdf -- converts jpeg images to hdf raster images 39 40 . hdf2jpeg -- converts hdf raster images to jpeg images 41 42 . fp2hdf -- converts 2D and 3D floating point data sets into HDF SDS. 43 44 45 46
