NAME

biffswap - swap byte order for bands in biff-file

SYNTAX

biffswap <infile> <outfile>

DESCRIPTION

Swap byte order for bands in biff-file. Works for all pixeltypes, including complex and double complex.

There is usually no need to use this program, because XITEtakes care of swapping bytes automatically. If an image(with multi-byte pixeltype) is written with an XITE versionprior to 3.0 and read with version 3.0 or later, or viceversa, use the following procedure.

Determine the version of your XITE copy either by running

xshowwith option -veror by reading the file$XITE_HOME/etc/.install/VERSION. If the option is notrecognized and the file does not exist, the version numberis less than 3.0.

Determine the endian-ness of the writing and reading hosts.

Examples of little-endian computers: DecStation, Dec alpha,PC (Intel x86).

Examples of big-endian computers: Sun, Silicon Graphics.

Image written with version < 3.0, read with version >= 3.0

If the writing host was little-endian, convert the imagefirst with the biffswapprogram (of version >= 3.0) on thereading host (regardless of reading host's endian-ness).Otherwise, no explicit conversion is necessary.

Image written with version >= 3.0, read with version < 3.0

This should not happen too often.

Writing host was little-endianWith a little-endian reading-host, convert the image withbiffswap(of version >= 3.0) on a big-endian machine.With a big-endian reading-host, the image can not be used.In this case, solve your problem by upgrading XITE on thereading-host.

Writing host was big-endianWith a little-endian reading-host, convert the image withbiffswap(of version >= 3.0) on a big-endian host or withbiffswap(of version < 3.0) on a little-endian host.With a big-endian reading-host, no explicit conversion isnecessary.
