<h2>NAME</h2>
ppmtoapplevol - convert a PPM into an Apple volume label image
<h2 id="synopsis">SYNOPSIS</h2>
<b>ppmtoapplevol</b>
[<i>ppmfile</i>]
<h2 id="description">DESCRIPTION</h2>
<p>This program is part of <a href="index.html">Netpbm</a>.
<p><b>ppmtoapplevol</b> reads a PPM image as input and produces an Apple
volume label image as output.
<p>EFI-based Apple systems use a simple image format to provide textual labels
for devices. This program generates that format.
<p>The input image must be exactly 12 rows tall and up to 255 columns wide.
The program fails if it is not. Use <b>pamfile</b> to see the dimensions of
your image and <b>pamscale</b> or <b>pamcut</b> to make it 12 rows and less
than 256 columns if it isn't.
<p>Netpbm does not have a converter for the other direction.
<h2 id="arguments">ARGUMENTS</h2>
<p>The optional <i>ppmfile</i> argument is the name of the input file.
The default is to read the input image from Standard Input.
<h2 id="options">OPTIONS</h2>
<p>There are no command line options defined specifically
for <b>ppmtoapplevol</b>, but it recognizes the options common to all
programs based on libnetpbm (See <a href="index.html#commonoptions">
Common Options</a>.)
