How do I pass parameter values to Popen?
<p>From the python console this works:</p>

<pre><code>convert -quality 100 in.pdf out.png
</code></pre>

<p>but when I add that command to my Python script like this:</p>

<pre><code>Popen(['convert', '-quality 100', 'in.pdf', 'out.png'])
</code></pre>

<p>I get:</p>

<pre><code>unrecognized option `-quality 100'
</code></pre>

<p>If I change that parameter to <code>'-quality=100'</code> I still get the error.</p>

<p>I tried fixing it like this:</p>

<pre><code>Popen(['convert', '-quality', '100', 'in.pdf', 'out.png'])
</code></pre>

<p>which runs but fails to produce an <code>out.png</code>.</p>

<p>UPDATE: The last version is working. I must have mistyped it originally.</p>
