title: How to increase acrofield(textfield) size to fit text in itext?
body: <p>I have a pdf template having a multi line textfield.While filling up the textfield at run-time using itext, I want to increase the textfield size so that the entire content is visible.
  I know similar questions have been posted previously.e.g. the following link suggests a solution but I am too new to itext to make it work.</p>
  
  <p><a href="https://stackoverflow.com/questions/12270556/how-to-display-floating-textfield-depending-on-the-text-content">How to display floating textfield depending on the text content?</a></p>
  
  <p>I know setting font size 0 automatically adjust the font size to fit in the text, but that is not an option for me since I can't reduce the font size.</p>
  
  <p>So kindly provide me an workable example if possible.</p>
