[iText-questions] Re: Problem inserting chunks and paragraphs

[Davi Garcia Pereira]

Bruno,

 

    If you can see my code I will be very thanks, this Visitor visits the tags nodes from a html and convert it to a Document. How you can see there isn't Strings addeds with PdfContentByte and my problem persists.

 

public class ParserVisitor extends NodeVisitor {
   
    private boolean negrito;
    private boolean italico;
    private boolean sublinhado;
   
    private float tamFonte;

    private LinkedList<com.lowagie.text.List> listaDeListas;
    private ListItem li;   
    private LinkedList<LinkedList<Cell>> tabela;
    private LinkedList<Cell> linhaDaTabela;
    private Cell celula;
    private boolean td = false;
    private Paragraph paragraph;
   
    private Document doc;

        this.doc = doc;

            paragraph.setSpacingAfter(30);

1) Mail to itext-questions@lists.sourceforge.net (instead of to the list
admin).
2) This is not true for Strings added with Chunk, Phrase, Paragraph,...
  This is normal for Strings added with showTextAligned (PdfContentByte).
  Both ways of adding content has its own purpose.
  It's explained in the online tutorial.
