<h2>NAME</h2>
pamtable - print the raster as a table of numerical sample values
<h2 id="synopsis">SYNOPSIS</h2>
<b>pamtable</b>
[<b>-tuple</b>]
[<b>-hex</b>]
[<i>netpbmfile</i>]
<h2 id="description">DESCRIPTION</h2>
<p>This program is part of <a href="index.html">Netpbm</a>.
<p><b>pamtable</b> 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:
<pre>
<span style="font-family: monospace">
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
</span>
</pre>
<p>There are other output formats possible. See the command line options.
<p>If you care to see only certain rows or columns, use <b>pamcut</b> to
filter the input.
<p>If you care to see only certain planes, use <b>pamchannel</b> to filter the
input.
<p><b>pamtable</b> prints vertical bars between tuples, unless there is only
one sample per tuple, in which case it prints a single space between tuples.
<p><b>pamtable</b> prints a single space between samples within a tuple.
<p>For each sample, <b>pamtable</b> 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.
<p>If you want the samples to print more densely, use <b>pamdepth</b> to
reduce the maxval (thus making the decimal numbers for the samples narrower).
<p>The <b>less</b> program (not part of Netpbm) is good for browsing through
the table. Use its <b>--chop-long-lines</b> option and use cursor movement
keys to scroll around in the image.
<h2 id="arguments">ARGUMENTS</h2>
<p>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.
<h2 id="options">OPTIONS</h2>
<p>In addition to the options common to all programs based on libnetpbm (most
notably <b>-quiet</b>, see <a href="index.html#commonoptions"> Common
Options</a>), <b>pamtable</b> recognizes the following command line options:
<dl compact>
<dt><b>-tuple</b>
<dd>Print the tuple values in mathematical tuple notation, like this:
<pre>
<span style="font-family: monospace">
(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)
</span>
</pre>
<p>This option was new in Netpbm 10.11.00 (September 2022).
<dt><b>-hex</b>
<dd>Display sample values in hexadecimal instead of decimal.
<p>This option is not valid with <b>-tuple</b>.
<p>This option was new in Netpbm 10.11.00 (September 2022).
<dt><b>-verbose</b>
<p>Print additional messages about the processing.
<dd>
