Comment trouver de l' (X, Y) la position dans iTextSharp?

Comme @Olaf dit, l'utilisation des GetVerticalPosition pour obtenir le Y. Le X est juste du document LeftMargin. Ci-dessous est un travail plein de WinForms application ciblant iTextSharp 5.1.1.0 qui nous l'espérons ne ce que vous cherchez:

using System;
using System.Text;
using System.Windows.Forms;
using iTextSharp.text;
using iTextSharp.text.pdf;
using System.IO;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
//Test file name
string TestFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Test.pdf");
//Standard iTextSharp setup
using (FileStream fs = new FileStream(TestFile, FileMode.Create, FileAccess.Write, FileShare.None))
{
using (Document doc = new Document(PageSize.LETTER))
{
using (PdfWriter w = PdfWriter.GetInstance(doc, fs))
{
//Open the document for writing
doc.Open();
//Will hold our current x,y coordinates;
float curY;
float curX;
//Add a paragraph
doc.Add(new Paragraph("It was the best of times"));
//Get the current Y value
curY = w.GetVerticalPosition(true);
//The current X is just the left margin
curX = doc.LeftMargin;
//Set a color fill
w.DirectContent.SetRGBColorStroke(0, 0, 0);
//Set the x,y of where to start drawing
w.DirectContent.MoveTo(curX, curY);
//Draw a line
w.DirectContent.LineTo(doc.PageSize.Width - doc.RightMargin, curY);
//Fill the line in
w.DirectContent.Stroke();
//Add another paragraph
doc.Add(new Paragraph("It was the word of times"));
//Repeat the above. curX never really changes unless you modify the document's margins
curY = w.GetVerticalPosition(true);
w.DirectContent.SetRGBColorStroke(0, 0, 0);
w.DirectContent.MoveTo(curX, curY);
w.DirectContent.LineTo(doc.PageSize.Width - doc.RightMargin, curY);
w.DirectContent.Stroke();
//Close the document
doc.Close();
}
}
}
this.Close();
}
}
}

N'est en fait que la position y de.

Mais si l'on a besoin de rendu de texte simple et, après que mettre une photo ou dessiner une ligne, il peut toujours compter la taille du texte affiché:

var chunk = new Chunk(String.Format("Sample text {0}", ));                                                             
document.Add(new Paragraph(t));
float curY = writer.GetVerticalPosition(false);
float x = document.Left + chunk.GetWidthPoint();
