<H2>NAME</H2>
pbmtoascii - convert a portable bitmap into ASCII graphics

<H2>SYNOPSIS</H2>
<B>pbmtoascii</B>
[<B>-1x2</B>|<B>-2x4</B>]

<H2>DESCRIPTION</H2>
Reads a portable bitmap as input.
Produces a somewhat crude ASCII graphic as output.
<P>
Note that there is no asciitopbm tool - this transformation is one-way.
<A NAME="lbAE">&nbsp;</A>
<H2>OPTIONS</H2>
The
<B>-1x2</B>
and
<B>-2x4</B>
flags give you two alternate ways for the bits to get mapped to characters.
With
<B>1x2</B>,
the default, each character represents a group of 1 bit across by 2 bits down.
With
<B>-2x4</B>,
each character represents 2 bits across by 4 bits down.
With the 1x2 mode you can see the individual bits, so it's useful for
previewing small bitmaps on a non-graphics terminal.
The 2x4 mode lets you display larger bitmaps on a standard 80-column display,
but it obscures bit-level details.
2x4 mode is also good for displaying
graymaps - &quot;pnmscale -width 158 | pgmnorm | pgmtopbm -thresh&quot;
should give good results.
