SYNOPSISpampick
image_sequence_number ...
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).
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 Stan‐
dard 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 enhance‐
ments 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 spec‐
ify 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.
