How do I set Paragraph indentation in iText?

By Wayan in iText PDF 0 Comment

To set paragraph indentation in the iText Paragraph object we can use the setFirstLineIndent(), setIndentationLeft() and setIndentationRight(). These methods accept a float value as a parameter.

The setFirstLineIndent() method set the first line indentation of a paragraph, while the setIndentationLeft() and setIndentationRight() methods set the left and the right indent of the paragraph. Let see an example below:

package org.kodejava.itextpdf;

import com.itextpdf.text.Chunk;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfWriter;

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

public class ParagraphIndentationDemo {
    private static final String CONTENT = """
            Lorem ipsum dolor sit amet, consectetur adipisicing elit, \
            sed do eiusmod tempor incididunt ut labore et dolore magna \
            aliqua. Ut enim ad minim veniam, quis nostrud exercitation \
            ullamco laboris nisi ut aliquip ex ea commodo consequat. \
            Duis aute irure dolor in  reprehenderit in voluptate velit \
            esse cillum dolore eu fugiat nulla pariatur. Excepteur sint \
            occaecat cupidatat non proident, sunt in culpa qui officia \
            deserunt mollit anim id est laborum.
            """;

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

            Paragraph paragraph = new Paragraph();
            paragraph.add(new Chunk(ParagraphIndentationDemo.CONTENT));

            // Set paragraph's first line indent
            paragraph.setFirstLineIndent(75);

            // Set paragraph's left side indent
            paragraph.setIndentationLeft(50);

            // Set paragraph's right side indent
            paragraph.setIndentationRight(25);
            document.add(paragraph);
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        } finally {
            document.close();
        }
    }
}
