title: Creating PDF/A with GhostscriptProcessor
body: <p>I want to convert a PDF file into PDF/A with GhostscriptProcessor, but the result is a PDF not PDF/A.</p>
  
  <pre><code>GhostscriptProcessor gsproc = new GhostscriptProcessor(Properties.Resources.gsdll32);
  gsproc.StartProcessing(CreatePDFA(@"C:\test\PDF.pdf", @"C:\test\PDFA.pdf"), new GsStdio());
  </code></pre>
  
  <p>And the method:</p>
  
  <pre><code>CreateTestArgs(string inputPath, string outputPath)
  {
      List&lt;string&gt; gsArgs = new List&lt;string&gt;();
      gsArgs.Add("-dPDFA");
      gsArgs.Add("-dBATCH");
      gsArgs.Add("-dNOPAUSEgsArgs");
      gsArgs.Add("-sDEVICE=pdfwrite");
      gsArgs.Add(@"-sOutputFile=" + outputPath);
      gsArgs.Add(@"-f" + inputPath);
      return gsArgs.ToArray();
  }
  </code></pre>
  
  <p>If I use gswin32.exe from the commandline the result is a PDF/A file.</p>
