I would like to pre-format the text in a form text-field, e.g. make it bold, italic or use a specific font. The following code generates a simple text-field:

\documentclass{scrreprt}
\usepackage{hyperref}
\begin{document}
\textbf{The Text Field}
\begin{Form}
\TextField[]{\ }
\end{Form}
\end{document}

Is it possible to pre-format the text in the text-field? The hyperref package manual (10/2011) speaks of an optional parameter format and the use of JavaScript to format the field. Can this be used to format the text in the field? And if yes, how is it done? (I am not proficient in JavaScript)

  • See the JavaScript™ for Acrobat® API Reference, p. 444 and surroundings for an overview of JavaScript in PDF formatting stuff. – doncherry Feb 26 '14 at 14:53
  • Stephan Lehmke: which fonts? Normally, pdfTeX does not embed complete fonts. Instead, it embeds subsets which contain the characters needed to display the content. Not only does this mean there is no guarantee a particular character is included in a subsetted font. These fonts also have weird (possibly unpredictable?) names. You can tell pdfTeX to embed complete fonts although this will obviously increase the file size. Is your question how to do that and how to use those fonts to format the text fields? – cfr Sep 24 '14 at 21:24
  • @cfr Exactly. Obviously, a font would need to be completely embedded to be used in a form field. Answers in Adobe forums tell that much. I know how to get pdftex to completely embed a font. Alas, so far no success to actually get that font to be used in a form field. Maybe an encoding problem? So the question really is how to use an embedded font in a Text Field reliably. – Stephan Lehmke Sep 27 '14 at 8:57
  • btw, the application I'm thinking about is producing "advertisement sheets" as preformatted PDF where only the "price tag" needs to be typed in before printing. – Stephan Lehmke Sep 27 '14 at 9:00
  • How exactly are you getting the font embedded and which font(s)? I doubt that Acrobat could use metafont or virtual fonts, for example. – cfr Sep 28 '14 at 1:01

I want to provide an example that shows most of the possibilities. I hope it helps:

\documentclass{article}
\usepackage[pdfstartview=FitH]{hyperref}

\begin{document}

\begin{Form}

\TextField[name = number.1,
           format = {
               var f = this.getField('number.1');
               f.textFont = 'Verdana';
               f.strokeColor = ['T'];
               f.fillColor = ['T'];
               f.userName = 'first number'
               },
           value = 1250,
           charsize = 10pt]
          {number 1}

\TextField[name = number.2,
           format = {
               var f = this.getField('number.2');
               f.textFont = 'Verdana';
               f.strokeColor = ['T'];
               f.fillColor = ['T'];
               f.userName = 'second number'
               },
           value = 500,
           charsize = 10pt]
          {number 2}

\TextField[name = sum,
           format = {
               var f = this.getField('sum');
               f.textFont = 'Verdana';
               f.strokeColor = ['T'];
               f.fillColor = ['T'];
               f.userName = 'sum'
               },
           calculate = {
               this.getField('sum').value =
                 this.getField('number.1').value + this.getField('number.2').value;
               },
           charsize = 10pt,
           readonly = true]
          {sum}

\end{Form}

\end{document}

This example was adapted from a German community.

    Thanks for the link. Do you have a solution for using TeX-fonts (embedded into the pdf-file) instead of system fonds? – Rainer Jan 8 '12 at 11:36
  • I would ask such a question at de.comp.text.tex. Heiko Oberdiek is very active there. (Maybe he will register here). You should link to this question here. – Marco Daniel Jan 8 '12 at 11:47

    How can I change this font-format global, meaning not in each textfield? – cis Feb 9 '16 at 21:25
  • @cis Try something like \renewcommand*{\DefaultOptionsofText}{format = { var f = this.getField(event.targetName); f.textFont = 'Verdana';}} – Fuhrmanator Aug 27 '18 at 3:21
  • @Rainer I know this is old, but you can generate a PDF with the embedded TeX font (make some text outside the form have that font), then look at the Properties of the PDF file generated. I used Segoe Marker in XeTeX and it came out as SegoeMarker when it was embedded. Doing f.textFont='SegoeMarker'; worked for me. – Fuhrmanator Aug 27 '18 at 3:27
