unu save: Write nrrd with specific format, encoding, or endianness. Use
"unu save -f pnm | xv -" to view PPM- or PGM-compatible nrrds on unix.
Usage: unu save -f <format> [-e <encoding>] [-en <endian>] [-i <nin>] \
[-o <nout>]
-f <format> = output file format. Possibilities include:
o "nrrd": standard nrrd format
o "pnm": PNM image; PPM for color, PGM for grayscale
o "text": plain ASCII text for 1-D and 2-D data
-e <encoding> = output file format. Possibilities include:
o "raw": raw encoding
o "ascii": print data in ascii
o "hex": two hex digits per byte
o "gzip", "gz": gzip compressed raw data
o "bzip2", "bz2": bzip2 compressed raw data
The specifiers for compressions may be followed by a colon
":", followed by an optional digit giving compression "level"
(for gzip) or "block size" (for bzip2). For gzip, this can be
followed by an optional character for a compression strategy:
o "d": default, Huffman with string match
o "h": Huffman alone
o "f": specialized for filtered data
For example, "gz", "gz:9", "gz:9f" are all valid
-en <endian> = Endianness of to save data out as; "little" for Intel and
friends; "big" for everyone else. Defaults to endianness of
this machine; default: "big"
-i <nin> = input nrrd
-o <nout> = output nrrd (string); default: "-"
