title: GIMP, python-fu: How to disable "Input image" and "Input drawable"
body: <p>i am confused a little about the art of how gimp generates the gui for python plug-ins.</p>
  
  <p>gimp generates two, for my script, needless fields. "Input image" and "Input drawable".
  how can i disable them?</p>
  
  <p>I didn't find anything about it in the standart documetation.</p>
  
  <p>my register method:</p>
  
  <pre><code>register(
    "fixPngColors",
    "fixPngColors",
    "fixPngColors",
    "Author",
    "Author",
    "2013",
    "&lt;Image&gt;/plug-ins/BATCH PNG Color Fix",
    "",
    [
    (PF_DIRNAME, "png_input_directory", "Png directory(INPUT)", ""),
    (PF_DIRNAME, "png_output_directory", "Png directory(OUTPUT)", ""),
    (PF_INT, "c_count", "Max Colors", "255"),
    ],
    [],
    launcher
    )
  </code></pre>
  
  <p>like you can see, nothing about the other two.</p>
