public class ClipboardMetafileHelper

// 14 == CF_ENHMETAFILE
bResult = hRes.Equals(hEMF2);
CloseClipboard();
}
}
}

}
return bResult;
}

public static Image GetEnhMetafileFromClipboard(IntPtr hWnd)
{

// IntPtr.Zero

if (hemf != IntPtr.Zero)

Bitmap b = new Bitmap(mf.Width, mf.Height);
Graphics g = Graphics.FromImage(b);
g.FillRectangle(Brushes.White, 0, 0, 1000, 1000);
GraphicsUnit unit = GraphicsUnit.Millimeter;
RectangleF rsrc = mf.GetBounds(ref unit);
g.DrawImage(mf, new Rectangle(0, 0, mf.Width, mf.Height), rsrc, unit);
return b;
}


return null;
