<H2>NAME</H2>
pbmtoascii - convert a PBM image to ASCII graphics
<H2 id="synopsis">SYNOPSIS</H2>

[<B>-1x2</B>|<B>-2x4</B>]
[<I>pbmfile</I>]
<H2 id="description">DESCRIPTION</H2>
<p>This program is part of <a href="index.html">Netpbm</a>.
<p><b>pbmtoascii</b> reads a PBM image as input and produces a somewhat
crude ASCII graphic image as output.
<P>To convert back, use <A HREF="asciitopgm.html">asciitopgm</A>.
<p><b>ppmtoterm</b> does a similar thing for color images to be displayed
on color text terminals.
<H2 id="options">OPTIONS</H2>
<p>The <B>-1x2</B> and <B>-2x4</B> options give you two alternate ways for the
pixels to get mapped to characters. With <B>1x2</B>, the default, each
character represents a group of 1 pixel across by 2 pixels down. With
<B>-2x4</B>, each character represents 2 pixels across by 4 pixels down. With
the 1x2 mode you can see the individual pixels, so it's useful for previewing
small images on a non-graphics terminal. The 2x4 mode lets you display larger
images on a small display, but it obscures pixel-level details. 2x4 mode is
also good for displaying PGM images:
<pre>
pamscale -width 158 | pnmnorm | pamditherbw -threshold | pbmtoascii -2x4
</pre>
should give good results.
