hdftor8 - extract 8-Bit raster images and palettes from HDF file
hdftor8 hdf-file [ -i] [ -v] [
-r raster-image-file] [ -p pallette-file]
extracts the raster images and/or palettes from an HDF file and
stores them in one file that contains the raster image data and another 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
If no name is given for the raster image file, the default name
"img.#.@.%" is assigned, where "#", "@", and
"%" are as defined in the preceding paragraph. The default name for
a palette file is "pal.#".
- Execute the program in interactive mode.
- Execute in verbose mode. Display diagnostic messages during the
- -r raster-image-file
- Specify the name of the raster image file.
- -p pallette-file
- Specify the name of the palette file.
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:
Six files are created, named "img1.512.256", "img2.512.256",
"img3.512.256", "pal.1", "pal.2", and
