title: Ghostscript Pdf Transparant Objects Removal
body: <p>I have several .pdf containing reoccuring transparent objects (text).
  (It has non transparant objects (text and vectors) as well as images) </p>
  
  <p><em>Not watermarks made by Acrobat or others.</em> <strong>It is in the background as styling.</strong></p>
  
  <p>To removing them manualy these is <strong>impossible</strong>, since the content on the pdf pages is mixed with the text on the page (grouping).</p>
  
  <p>Is there a way to <strong>alter</strong> the <strong>opacity</strong> of translucent objects to <strong>0</strong>. Or even <strong>removing</strong> <strong>them</strong> completely from the pdf, with ghostscript?
  <em>Using adobe acrobat pre-flight, and moving them as images, removes all of the images in the pdf, instead of only the transparent objects.</em></p>
  
  <ul>
  <li><strong>How can this be achieved with the help of Ghostscript and the
  appropriate PostScript code?</strong></li>
  </ul>

  </ul>
  
  <p>Where helpful, to know how to get objects and images, but not filtering specifically for transparent objects.</p>
  
  <p>Any ideas are appreciated as well.</p>
