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. SEE ALSO

r8tohdf - convert 8-bit raster images to HDF format SYNOPSIS
r8tohdf [number-of-rows number-of-columns] output-filename [-p palette-filename] [-c] [-r] [-i] raw-raster-image-filename-1, raw-raster- image-filename-2, ... DESCRIPTION
r8tohdf converts a set of raw raster images to the HDF RIS8 format and writes them to a file. OPTIONS
-p pallette-file Specify the name of the palette file. -c Run length coding. Compress the output data using run-length encoding. -i IMCOMP Compression. Compress the output data using the IMCOMP method. -r No Compression. Apply no compression to the output data. (the default). EXAMPLES
A file named "rawras" contains a 256 x 512-byte raw raster image, and its palette is stored in a file name "mypal". To convert the informa- tion in these files to an RIS8 without compression and store the RIS8 in a file named "ras.hdf", enter the following r8tohdf command: r8tohdf 256 512 ras.hdf -p mypal rawras A 800 x 1000-byte raw raster image is stored in a file named "bigpic". This data must be converted to a RIS8 without a palette, compress- ing it using run-length encoding, then stored in a file named "bigpic.hdf". The following command will do this: r8tohdf 800 1000 bigpic.hdf -c bigpic A 300 x 400 raw raster image is contained in each of the files named "pic1", "pic2", and "pic3". To convert all three files to RIS8s, com- press them using the IMCOMP method, and store them in a file named "pic.hdf", enter r8tohdf 300 400 pic.hdf -i pic1 pic2 pic3 Different types of raster image data are to be stored in a file named "ras.hdf". The image data in the file "rawras1" will be stored with- out a palette. The image data sets from the file named "rawras2" are to be stored with a palette extracted from a file named "mypal". The images from the "rawras1" and "rawras2" files are to be compressed using run-length encoding, and the image in the "rawras3" file is not to be compressed. The size of all images are 256 x 512 bytes. The following command is used to do this: r8tohdf 256 512 ras.hdf -c rawras1 -p mypal rawras2 -r rawras3 SEE ALSO
