NAME
hdftor8 - extract 8-Bit raster images and palettes from HDF file SYNOPSIS
hdftor8 hdf-file [-i] [-v] [-r raster-image-file] [-p pallette-file] DESCRIPTION
hdftor8 extracts the raster images and/or palettes from an HDF file and stores them in one file that contains the raster image data and an- other that contains the palette data. The names given for the raster image and palette files are interpreted by hdftor8 as follows: For each raster image file, the file name is given the extension ".#.@.%", where "#" represents the raster image number from the HDF file, "@" represents the x-dimension of the raster image, and "%" represents the y-dimension of the raster image. For each palette file, the file name is given the extensions ".#", where "#" represents the palette number from the HDF format file. If no name is given for the raster image file, the default name "img.#.@.%" is assigned, where "#", "@", and "%" are as defined in the pre- ceding paragraph. The default name for a palette file is "pal.#". OPTIONS
-i Execute the program in interactive mode. -v Execute in verbose mode. Display diagnostic messages during the session. -r raster-image-file Specify the name of the raster image file. -p pallette-file Specify the name of the palette file. EXAMPLES
A file named "denm.hdf" contains three 512 x 256 raster images and three palettes. To store these images and palettes in separate raster image and palette files, use the following hdftor8 command: hdftor8 denm.hdf Six files are created, named "img1.512.256", "img2.512.256", "img3.512.256", "pal.1", "pal.2", and "pal.3".

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 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
