  Expression relating paragraph lines with font size

  Posted by Cesar Rattoni on December 20, 2021 at 8:07 pm

  Hello everyone,

  I am trying to create a script that links the font size in a paragraph with the number of lines of the same paragraph, in the following way:

  If the number of lines is 3 or less leave the font-size value the way it is, otherwise decrease the font size until it reaches 3 lines. 

  I found Andrei Popa’s line counter, which works great, and I tried to use it with a for statement in with a setFontSize script but I kept getting error messages. 

  Any suggestions?

  Andrei Popa’s script is this one:

  L = thisComp.layer("Text Layer");
  var newStyle = L.text.sourceText.style;
  var myLeading = newStyle.autoLeading ? newStyle.fontSize * 1.2 : newStyle.leading;
  H = L.sourceRectAtTime(time, false).height;
  rowNo = Math.ceil(H / myLeading);
  rowNo;
