rassplit
Description
The program rassplit will open rasterfile and
copy each frame to it's own separate output file. By default, all
frames are extracted but the user can optionally request a specific
set of frames using the -f option. The output format
defaults to be the same as the input format, but the user can also
optionally select a new output format using the -ofmt
option.
The names of the output rasterfiles are derived from the name
of the source rasterfile, the output format, and
the frame numbers. The examples given below will demonstrate
this.
Synopsis
rassplit
[-f f1 f2 f3 ...]
[-ofmt output-format]
[-verbose]
[-Version]
[-help]
rasterfile
Options
- -f f1 f2 f3 ...
- This option allows the user to specify a list of frames
to be extracted from the input rasterfile.
- -ofmt output-format
- The user can specify output-format to be the desired
format e.g. hdf, rgb, etc.
- -help
- Print help information.
- -verbose
- Print a message each time an output rasterfile is written.
- -Version
- Print the version number.
Examples
Assume you have a file called 'temp.nrif' that has three frames and
that you'd like to split it into three separate frames, also in NRIF
format.
rassplit temp.nrif
This will result in three output files named temp.0001.nrif,
temp.0002.nrif, and temp.003.nrif.
Assume you only want frames two and three, and you want them produced
in HDF format instead of NRIF.
rassplit -fmt hdf -f 2 3 temp.nrif
This will result in two output files named temp.0001.hdf and
temp.0002.hdf.
Caveats
If you're splitting an HDF file, ask for a non-HDF output
format. Otherwise you'll just get the first frame over and
over again.
