NAME
pamsplit - split a multi-image Netpbm file into single-image files
SYNOPSIS
pamsplit
[netpbmfile
[ output_file_pattern]]
[-padname=n]
Minimum unique abbreviation of option is acceptable. You may use dou-
ble hyphens instead of single hyphen to denote options. You may use
white space in place of the equals sign to separate an option name from
its value.
DESCRIPTION
This program is part of Netpbm(1).
pamsplit reads a PNM or PAM stream as input. It copies each image in
the input into a separate file, in the same format.
netpbmfile is the file name of the input file, or - to indicate Stan-
dard Input. The default is Standard Input.
output_file_pattern tells how to name the output files. It is the file
name of the output file, except that the first occurrence 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,
pamsplit fails.
The default output file pattern is "image%d".
The -padname option specifies to how many characters you want the image
sequence number in the output file name padded with zeroes. pamsplit
adds leading zeroes to the image sequence number to get up to at least
that number of characters. This is just the number of characters in
the sequence number part of the name. For example, pamsplit - output-
file%d.ppm -padname=3 would yield output filenames outputfile000.ppm,
outputfile001.ppm, etc.
The default is no padding (equivalent to -padname=0).
The -padname option was new in Netpbm 10.23 (July 2004). Before that,
there was never any padding.
Note that to do the reverse operation (combining multiple single-image
Netpbm files into a multi-image one), there is no special Netpbm pro-
gram. Just use cat.
If you just want to find out basic information about the images in a
stream, you can use pamfile on the stream.
To extract images from a stream and generate a single stream containing
them, use pampick.
To run a program on each image in a stream without the hassle of tempo-
rary files, use pamexec.
