title: Can FAXCOMEXLib and Windows Fax Service send a color fax?
body: <p>We are in the process of testing different options for sending faxes from within our C# code (receiving faxes is not necessary).  One of those options is to use FAXCOMEXLib.  </p>
  
  <p>Without surprise, I've had pretty good success sending out black &amp; white faxes with FAXCOMExLib.  But we also have a requirement to support sending color faxes.  So I execute the following code (just a snippet):</p>
  
  <pre><code>IFaxDocument oFaxDoc = new FaxDocumentClass();
  oFaxDoc.Body = @"C:\Test\color_image.jpg";
  oFaxDoc.ConnectedSubmit(m_oFaxServer);
  </code></pre>
  
  <p>The image is 24bit color, 1728x2304, 204x196 dpi.</p>
  
  <p>For the most part, this process works (with a couple of small quirks) and the fax shows up in my "Windows Fax and Scan" outbox (I'm on Vista).  The problem is the image has been dithered to a 1bit black &amp; white image.  I assume that what I see in "Windows Fax and Scan" is what is actually transmitted.  </p>
  
  <p>So is there a way to send a color fax using this technology?  Are we missing a configuration option somewhere to make it work?</p>
