title: In what way does the page rotation influence a given form field in a PDF?
body: <p>I am having a hard time understanding exactly what is expected per the PDF spec regarding page vs form field rotations.</p>
  
  <p>The simplest example is a PDF with a single Page with a single textbox form field in the very center with some default text. Without messing with anything else, we see the text read horizontally.</p>
  
  <p>If we change the Page rotation to 90, would it be expected that the text is now vertical and sideways?</p>
  
  <p>If we leave the Page rotation at 90 and then set the textbox's rotation to 90, would it be expected that the text is now upside down?</p>
  
  <p>I have the second situation in a PDF I'm working with currently (which I can't share) and I see the text appear as if the Page and textbox rotations were 0. Obviously that must be correct if that's what Acrobat and other PDF readers show but if someone could explain a little why that's the case it would be much appreciated!</p>
