NAME
pamtable - print the raster as a table of numerical sample values
SYNOPSIS
pamtable
[netpbmfile]
DESCRIPTION
This program is part of Netpbm(1).
pamtable prints the raster of a Netpbm image as a table of numerical
sample values. For example, a 5-pixel wide, 2-pixel high rainbow
(black, red, green, blue, white) PPM image with maxval 255 would appear
as follows:
0 0 0|255 0 0| 0 255 0| 0 0 255|255 255 255
0 0 0|255 0 0| 0 255 0| 0 0 255|255 255 255
If you care to see only certain rows or columns, use pamcut to filter
the input.
If you care to see only certain planes, use pamchannel to filter the
input.
pamtable prints vertical bars between tuples, unless there is only one
sample per tuple, in which case it prints a single space between tu-
ples.
pamtable prints a single space between samples within a tuple.
For each sample, pamtable prints the numerical value from the Netpbm
image, uninterpreted. It prints it in decimal, right justified in the
minimum number of spaces required to print the maxval of the image.
If you want the samples to print more densely, use pamdepth to reduce
the maxval (thus making the decimal numbers for the samples narrower).
The less program (not part of Netpbm) is good for browsing through the
table. Use its --chop-long-lines option and use cursor movement keys
to scroll around in the image.
ARGUMENTS
The only possible argument is the name of the file containing the input
Netpbm image. This is optional; if you don't specify any arguments,
the input comes from Standard Input.
OPTIONS
There are no command line options defined specifically for pamtable,
but it recognizes the options common to all programs based on libnetpbm
(See
Common Options ⟨index.html#commonoptions⟩ .)
