Merge two Paragraph objects

Question

I want to insert a piece of text in a PDF which contains bold and not-bold areas, but I do not know how can I do this ?

I'm using iText5 (java).

This is my code:

Click to copy

public class CreatePdf{
   private Font bigFont = FontFactory.getFont(FontFactory.HELVETICA, "Windows-1254", 12, Font.BOLD, new Color(0, 0, 0));
   private Font smallFont = FontFactory.getFont(FontFactory.HELVETICA, "Windows-1254", 8, Font.NORMAL, new Color(0, 0, 0));

   public void create(){
      Paragraph parag1=new Paragraph("Number: ",bigFont);//This gonna be bold font
      Paragraph parag2=new Paragraph("12", smallFont); //This gonna be normal font

      //Create one paragraph from these two paragraphs. But How ?
   }
}

Answer 1

You can make simpler:

Click to copy

comb.add(parag1);
comb.add(parag2);

The Chunk is not necessary.
