NAME
       hdftopal, paltohdf - convert between a palette in an HDF file and a raw palett e in a non-HDF file

SYNOPSIS
       hdftopal hdf-pallette-file raw-pallette-file
       paltohdf raw-pallette-file hdf-pallette-file

DESCRIPTION
       hdftopal  converts  a  palette  in  an HDF file to a raw palette in an non-HDF file. The raw palette will have 768 bytes with the first 256
       bytes representing red intensity values, the second 256 bytes representing green intensity values, and the  third  256  bytes  representing
       blue intensity values.

       paltohdf  performs the converse conversion, from raw palette data to the HDF palette format. The raw palette data must have 768 bytes orga-
       nized in the following order: first, 256 contiguous red intensity values, then 256 contiguous green intensity values, then  256	contiguous
       blue intensity values. The palette in the HDF file will have the RGB values pixel-interlaced, as follows:

       red-value green-value blue-value red-value green-value blue-value...

       This is the standard HDF format for 8-bit palettes.

       If  an HDF palette format file is specified that doesn't exist, it is created before the converted data is stored. If an HDF palette format
       file is specified that already exists, the converted data is appended to the file.
