I need to create a PDF with several sections, and after each section need to add a line, but I don't know where to draw this line.
I need to find the exact coordinates [x, y] where the next element in the document will be write.
Like @Olaf said, use GetVerticalPosition
to get the Y
. The X
is just the document's LeftMargin
. Below is a full working WinForms app targeting iTextSharp 5.1.1.0 that hopefully does what you are looking for:
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();
}
}
}
I believe there is only the y-position available: try
PdfWriter.getVerticalPosition()
