Compress an hdf file
Usage
hdfpack [{-i | -b}]
[-d
data-descriptors-per-block]
[-t
linked-blocks-per-table-entry]
input-hdf-file
output-hdf-file
Overview
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.
hdfpackwill not coalesce linked-block elements.
-
-i -
Interactive Mode.
hdfpackwill prompt for each linked-block element.
-dnum-
Write an output file with the specified number of data descriptors per block of data descriptors.
-tnum-
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 command:
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
