How to enable anti-aliasing when rendering WMF to BitMap in C#/WPF/WinForms?
<p>Why won't lines etc be anti-aliased when doing this?</p>

<pre><code>using (var myGraphics = Graphics.FromImage(bitmap))
{
myGraphics.CompositingQuality = CompositingQuality.HighQuality;
myGraphics.SmoothingMode = SmoothingMode.HighQuality;
myGraphics.TextRenderingHint = TextRenderingHint.AntiAliasGridFit;

myGraphics.Clear(backgroundColor);

myGraphics.EnumerateMetafile(m_metafile, new Point(0, 0), m_metafileDelegate);
}
</code></pre>

<p>The delegate function looks like this:</p>

<pre><code>private bool MetafileCallback(EmfPlusRecordType recordType, int flags, int dataSize, IntPtr data, PlayRecordCallback callbackData)
{
        byte[] dataArray = null;
        if (data != IntPtr.Zero)
        {
            // Copy the unmanaged record to a managed byte buffer 
            // that can be used by PlayRecord.
            dataArray = new byte[dataSize];
            Marshal.Copy(data, dataArray, 0, dataSize);
        }

        m_metafile.PlayRecord(recordType, flags, dataSize, dataArray);

        return true;
}
</code></pre>

<p>Do I need to override PlayRecord for a specific type to get anti-aliasing here?</p>

<p>The WMFs come from AutoCAD, if that's any help.</p>
