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".
