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 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 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 preceding 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".
