NAME

       hdfpack - compress an HDF file

SYNOPSIS

       hdfpack [-i|-b] [-d data-descriptors-per-block] [-t linked-blocks-per-table-entry] input-hdf-file output-hdf-file

DESCRIPTION

       hdfpack compresses all of the data in an HDF file and writes the compressed data to a second HDF file.

OPTIONS

       -b     Non-coalesced Blocks.  hdfpack will not coalesce linked-block elements.

       -i     Interactive Mode.  hdfpack will prompt for each linked-block element.

       -d num Write an output file with the specified number of data descriptors per block of data descriptors.

       -t num Write an output file with the specified number of linked blocks per table entry.

EXAMPLES

       To  compress  the  data in the file named "aa.hdf" and store the compressed data in the file named "aa.cmp", use the following hdfpack com-
       mand:

	       hdfpack aa.hdf aa.cmp

       Suppose a file named "bb.hdf" contains data elements stored as sequences of linked blocks. The following  hdfpack  command  compresses  the
       file while leaving the linked-block elements intact, and writes the compressed data to a file named "bb.blk".

	       hdfpack -b bb.hdf bb.blk

NAME

       hdftor8 - extract 8-Bit raster images and palettes from HDF file

SYNOPSIS

       hdftor8 hdf-file [-i] [-v] [-r raster-image-file] [-p pallette-file]

DESCRIPTION

       hdftor8 extracts the raster images and/or palettes from an HDF file and stores them in one file that contains the raster image data and an-
       other that contains the palette data.

       The names given for the raster image and palette files are interpreted by hdftor8 as follows: For each raster image file, the file name	is
       given  the extension ".#.@.%", where "#" represents the raster image number from the HDF file, "@" represents the x-dimension of the raster
       image, and "%" represents the y-dimension of the raster image. For each palette file, the file name is given the extensions ".#", where "#"
       represents the palette number from the HDF format file.

       If no name is given for the raster image file, the default name "img.#.@.%" is assigned, where "#", "@", and "%" are as defined in the pre-
       ceding paragraph. The default name for a palette file is "pal.#".

OPTIONS

       -i     Execute the program in interactive mode.

       -v     Execute in verbose mode. Display diagnostic messages during the session.

       -r raster-image-file
	      Specify the name of the raster image file.

       -p pallette-file
	      Specify the name of the palette file.

EXAMPLES

       A file named "denm.hdf" contains three 512 x 256 raster images and three palettes. To store these images and palettes  in  separate  raster
       image and palette files, use the following hdftor8 command:

	       hdftor8 denm.hdf

       Six files are created, named "img1.512.256", "img2.512.256", "img3.512.256", "pal.1", "pal.2", and "pal.3".
