what namespaces are needed for this piece of code? (c#)
<pre><code>Image Dummy = Image.FromFile("image.png");
Dummy.Save("image.bmp", ImageFormat.Bmp);
</code></pre>

<p>what the question says</p>

<p>i have these</p>

<pre><code>using System;
using System.Drawing;
using System.Drawing.Imaging;
using System.Drawing.Drawing2D;
</code></pre>

<p>but i get an error saying that the namespace drawing does not exist in the namespace system :/</p>
