description
Reads a Netpbm
file as input. Copies each image in the input into a
separate file, in the same format.
pnmfile
is the file specification of the input file, or - to
indicate Standard Input. The default is Standard Input.
output_file_pattern
tells how to name the output files. It is the file
specification of the output file, except that the first
occurence of "%d" in it is replaced by the image
sequence number in unpadded ASCII decimal, with the sequence
starting at 0. If there is no "%d" in the pattern,
pnmsplit fails.
The default
output file pattern is "image%d".
Note that to do
the reverse operation (combining multiple single-image PNM
files into a multi-image one), there is no special Netpbm
program. Just use cat.
