6 rassplit - split a multi-frame rasterfile into single-frame raster‐
7 files.
8
10 rassplit [-f f1 f2 f3 ...] [-ofmt output-format] [-verbose] [-Version]
11 rasterfile
12
14 The program rassplit will open rasterfile and copy each frame to it's
15 own separate output file. By default, all frames are extracted but the
16 user can optionally request a specific set of frames using the -f
17 option. The output format defaults to be the same as the input format,
18 but the user can also optionally select a new output format using the
19 -ofmt option.
20
21 The names of the output rasterfiles are derived from the name of the
22 source rasterfile, the output format, and the frame numbers. The exam‐
23 ples given below will demonstrate this.
24
26 -f f1 f2 f3 ...
27 This option allows the user to specify a list of frames to be
28 extracted from the input rasterfile.
29
30 -ofmt output-format
31 The user can specify output-format to be the desired format e.g.
32 hdf, rgb, etc.
33
34 -help Print help information.
35
36 -verbose
37 Print a message each time an output rasterfile is written.
38
39 -Version
40 Print the version number.

44 Assume you have a file called 'temp.nrif' that has three frames and
45 that you'd like to split it into three separate frames, also in NRIF
46 format.
47
48 rassplit temp.nrif
49
50 This will result in three output files named temp.0001.nrif,
51 temp.0002.nrif, and temp.003.nrif.
52
53 Assume you only want frames two and three, and you want them produced
54 in HDF format instead of NRIF.
55
56 rassplit -fmt hdf -f 2 3 temp.nrif
57
58 This will result in two output files named temp.0001.hdf and
59 temp.0002.hdf.
60
61
63 If you're splitting an HDF file, ask for a non-HDF output format. Oth‐
64 erwise you'll just get the first frame over and over again.
