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

createhdf - Create a blank IDE hard disk image in .hdf format SYNOPSIS
createhdf [ -c ] [ -s ] cylinders heads sectors file DESCRIPTION
createhdf creates a blank image of an IDE hard disk in .hdf format for use with Sinclair ZX Spectrum emulators. OPTIONS
-c specifies that the .hdf image should be created in `compact' mode, where only the low byte of every word is stored in the image. This is useful for saving space if the hard disk image is for use with an interface which accesses only the low byte of every word. -s specifies that the .hdf image should not be created as a sparse file. Normally, createhdf will attempt to create the hard disk image as a `sparse file', where the operating system knows that the file consists mostly of zero bytes and fills those in without using any space in the file. This option disables this. (There's nothing `magic' about this: if data is written to the file, it will take up space just like any other data; it's only empty space which is synthesised by the operating system). -v version specifies the version of .hdf image to be created. Valid values are `1.0' for a version 1.0 file and `1.1' for a version 1.1 file. Defaults to creating version 1.1 files. cylinders specifies the number of cylinders in the image. heads specifies the number of heads in the image. sectors specifies the number of sectors in the image. file specifies the file to which the image should be written.
