How do I create an ordered list in iText 8?

By I Wayan Saryada in iText PDF 0 Comment

Creating an ordered list in iText 8 involves creating a List object and adding ListItem objects to it, similarly to creating an unordered list.

For automatic numbering or bullets in a list, you’ll have to use ListNumberingType with the appropriate configuration. For example, ListNumberingType.DECIMAL for Arabic number (1, 2, 3, etc.) and ListNumberingType.ENGLISH_LOWER for English lower case alphabet (a, b, c, etc.).

Here’s an example:

package org.kodejava.itext;

import com.itextpdf.kernel.pdf.PdfDocument;
import com.itextpdf.kernel.pdf.PdfWriter;
import com.itextpdf.layout.element.List;
import com.itextpdf.layout.element.ListItem;
import com.itextpdf.layout.Document;
import com.itextpdf.layout.properties.ListNumberingType;

public class OrderedListExample {
    public static void main(String[] args) throws Exception {
        PdfDocument pdfDoc = new PdfDocument(new PdfWriter("output.pdf"));
        try (Document doc = new Document(pdfDoc)) {
            // Create a List object and set numbering type
            List list = new List(ListNumberingType.DECIMAL);

            // Add ListItems
            list.add(new ListItem("First item"));
            list.add(new ListItem("Second item"));
            list.add(new ListItem("Third item"));
            list.add(new ListItem("Fourth item"));

            // Add the list to our document
            doc.add(list);
        }
    }
}

In this example, we’re passing ListNumberingType.DECIMAL to the List constructor. This will number our list items as follows: “1.”, “2.”, “3.”, etc.

Other options you’ll find in the ListNumberingType enum are:

  • DECIMAL_LEADING_ZERO
  • ENGLISH_LOWER
  • ENGLISH_UPPER
  • ROMAN_LOWER
  • ROMAN_UPPER
  • GREEK_LOWER
  • GREEK_UPPER
  • ZAPF_DINGBATS_1
  • ZAPF_DINGBATS_2
  • ZAPF_DINGBATS_3
  • ZAPF_DINGBATS_4

How do I create an unordered list in iText 8?

By I Wayan Saryada in iText PDF 0 Comment

Creating an unordered list in iText 8 involves creating a List object and adding ListItem objects to it.

Here is an example of how you can do this:

package org.kodejava.itext;

import com.itextpdf.layout.Document;
import com.itextpdf.layout.element.List;
import com.itextpdf.layout.element.ListItem;
import com.itextpdf.kernel.pdf.PdfDocument;
import com.itextpdf.kernel.pdf.PdfWriter;

public class UnorderedListExample {
    public static void main(String[] args) throws Exception {
        PdfDocument pdfDoc = new PdfDocument(new PdfWriter("output.pdf"));
        try (Document doc = new Document(pdfDoc)) {
            // Create a List object
            List list = new List();
            list.setListSymbol("\u2022 ");

            // Add ListItems
            list.add(new ListItem("First item"));
            list.add(new ListItem("Second item"));
            list.add(new ListItem("Third item"));
            list.add(new ListItem("Fourth item"));

            // Add the list to our document
            doc.add(list);
        }
    }
}

In this code:

  • A PdfDocument object is created to write to a PDF file named “output.pdf”.
  • A Document object is created, which represents an actual PDF document.
  • A List object is created, representing the unordered list.
  • ListItem objects representing individual list items are added to the List.
  • Finally, the List is added to the Document, and the Document is automatically closed by the try-with-resource block, and flush any remaining content to the PDF.

You may put different things in your ListItem objects, and nest other List objects within them, if you wish.

How do I create a List in iText?

By I Wayan Saryada in iText PDF 0 Comment

You can create a list in iText using the com.itextpdf.text.List. This class represent a list. The list item is created using the com.itextpdf.text.ListItem. You can create an ordered list or unordered list. To create ordered list pass the List.ORDERED as the parameter to class List. To create an unordered list pass the List.UNORDERED.

Let’s see an example below:

package org.kodejava.itextpdf;

import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.List;
import com.itextpdf.text.ListItem;
import com.itextpdf.text.pdf.PdfWriter;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;

public class ListDemo {
    public static void main(String[] args) {
        Document document = new Document();
        try {
            PdfWriter.getInstance(document, new FileOutputStream("ListDemo.pdf"));
            document.open();

            List ordered = new List(List.ORDERED);
            ordered.add(new ListItem("Item 1"));
            ordered.add(new ListItem("Item 2"));
            ordered.add(new ListItem("Item 3"));
            document.add(ordered);

            List unordered = new List(List.UNORDERED);
            unordered.add(new ListItem("Item 1"));
            unordered.add(new ListItem("Item 2"));
            unordered.add(new ListItem("Item 3"));
            document.add(unordered);
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        } finally {
            document.close();
        }
    }
}
