R8TOHDF(1) General Commands Manual R8TOHDF(1)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

Hi,
I would like to list files: ls *.hdf
But I would like a copy of the output directed to the screen, but also APPENDED to a text file: test.txt
I have tried:
ls *.hdf | tee test.txt
However, that will just write over everything already existing in test.txt. How can I append the... (1 Reply)
Hi,
I am using a PPC Mac running OS 10.4
I have a directory containing a bunch of files. When viewed with the Finder one file is called 2007009-2007016.s0481pfrt-sst.hdf (normal). However, when I type 'ls' in a terminal, the file is called 200700~2.HDF (odd).
What is even odder is that I... (2 Replies)
I found a script from HDF-EOS for converting HDF to TIF, i did all steps but when i run there is some errors.
