NAME
pampick - pick images out of a multi-image Netpbm image stream
SYNOPSIS
pampick image_sequence_number ...
Minimum unique abbreviation of
option is acceptable. You may use double
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.
pampick reads a PNM or PAM image
stream as input. It picks certain images
from the stream and copies them to a new image stream on
Standard Output.
You identify the images to pick
by sequence number within the stream. Each
image_sequence_number is a decimal sequence number, with
zero meaning the
first image.
The arguments must be in
increasing order, without duplicates. The results
are undefined if they are not. (There are a number of
enhancements that
might be made in future releases that would make whatever
pampick does today
when you break this rule change). pampick outputs the images
in the same
order as they appear in the input. If you specify no
sequence numbers,
pampick outputs nothing. If you specify a sequence number
that is beyond
what is in the input, pampick fails with an error message to
that effect.
pampick always reads the entire
input stream. (This is helpful when the
input stream is a pipe and whatever is feeding the pipe
would be upset if it
filled up or broke).
To see how many images, and what kind, are in a stream, use pamfile.
To extract all the images in a
stream into separate named files, use
pamsplit.
