title: Rotate a PDF without changing orientation
body: <p>while the topic of my question seems to be a well supported feature of many PDF manipulation packages and tools out there, I need to make clear that I don't want to rotate the PDF. </p>
  
  <p>I have a PDF that exposes a portrait orientation (A4) with dimensions WxH 297x210 (A4 rotated).</p>
  
  <p>Now, what I need to achieve, is that this PDF has landscape orientation while preserving the dimensions. </p>
  
  <p>I am not sure what this requires me to do. </p>
  
  <p>If I use Adobe Illustrator to change document format to the desired position, I also need to rotate the contents. If I put this page into the badly designed PDF, the formfields and all annotations on this page are still in the portrait orientation.</p>
  
  <p>How can I rotate them to match the new page orientation? There seems to be no tool support for this kind of task.</p>
  
  <p>Thanks for your support!</p>
  
  <p>Thomas</p>
