EPS

[Trevor Curtis <tcurtis somaradio ca>]

A while ago, there was a thread about changing the way we insert screen
shots into our docs. Currently it was suggested to use:

<screenshot id="id">
<mediaobject>
<imageobject>
<imagedata fileref="path/to/image.png" format="PNG"/>
</imageobject>
<imageobject>
<imagedata fileref="path/to/image.eps" format="EPS"/>
</imageobject>
<textobject>
<phrase>Acessibility description</phrase>
</textobject>
<caption>
<para>Description of the screenshot.</para>
</caption>
</mediaobject>
</screenshot>


My question is why is it necessary to have an eps file?

cheers,
TC
