NAME

       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  information  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, compressing 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, compress 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 without 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
