How do I set Paragraph alignment in iText?

By I Wayan Saryada in iText PDF 1 Comment

To set the alignment of a paragraph object we can use the Paragraph.setAlignment() method. We can pass constants such as Paragraph.ALIGN_LEFT, Paragraph.ALIGN_CENTER, Paragraph.ALIGN_RIGHTto the setAlignment() method.

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 ParagraphAlignment {
    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 \

            """;

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

            // Creates a check for the paragraphs contents
            Chunk chunk = new Chunk(ParagraphAlignment.CONTENT);

            // Creates paragraphs and set the alignment of the paragraph.
            // We use the Paragraph.ALIGN_LEFT, Paragraph.ALIGN_CENTER
            // and Paragraph.ALIGN_RIGHT
            Paragraph para1 = new Paragraph(chunk);
            para1.setAlignment(Paragraph.ALIGN_LEFT);
            para1.setSpacingAfter(50);
            document.add(para1);

            Paragraph para2 = new Paragraph(chunk);
            para2.setAlignment(Paragraph.ALIGN_CENTER);
            para2.setSpacingAfter(50);
            document.add(para2);

            Paragraph para3 = new Paragraph(chunk);
            para3.setAlignment(Paragraph.ALIGN_RIGHT);
            document.add(para3);

            document.close();
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        }
    }
}

How do I set Paragraph line space in iText?

By I Wayan Saryada in iText PDF 0 Comment

To set the line spacing of a paragraph in iText can be done by passing the line space / leading argument in the Paragraph constructor. In the example below we set the line space to 32. We can also set the space between paragraph by calling the setSpacingBefore() and setSpacingAfter() methods of this object.

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 ParagraphLineSpaceDemo {
    public static void main(String[] args) {
        Document doc = new Document();

        try {
            FileOutputStream fos = new FileOutputStream("ParagraphLineSpace.pdf");
            PdfWriter.getInstance(doc, fos);
            doc.open();

            String content = "The quick brown fox jumps over the lazy dog";

            // Setting paragraph line spacing to 32
            Paragraph para1 = new Paragraph(32);

            // Setting the space before and after the paragraph
            para1.setSpacingBefore(50);
            para1.setSpacingAfter(50);
            for (int i = 0; i < 10; i++) {
                para1.add(new Chunk(content));
            }
            doc.add(para1);

            Paragraph para2 = new Paragraph();
            for (int i = 0; i < 10; i++) {
                para2.add(new Chunk(content));
            }
            doc.add(para2);

            doc.close();
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        }
    }
}

How do I use iText Paragraph class?

By I Wayan Saryada in iText PDF 0 Comment

The com.itextpdf.text.Paragraph class represent a paragraph in PDF document. The following example show you how to create a simple paragraph. First we create a Paragraph object and then add some texts into it using the Chunk object.

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

            String content = "The quick brown fox jumps over the lazy dog";
            Paragraph paragraph = new Paragraph();
            for (int i = 0; i < 20; i++) {
                Chunk chunk = new Chunk(content);
                paragraph.add(chunk);
            }

            doc.add(paragraph);
            doc.close();
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        }
    }
}

How do I customize the Phrase object in iText?

By I Wayan Saryada in iText PDF 0 Comment

This example shows how to customize the iText Phrase object. We can change the default line spacing of the Phrase object by passing a float parameter. We can also use the setLeading() method.

We can also set the default font for the Phrase so that every Chunk added to this object will have the same font. If you want the chunk to have a different font, you can set it in the chunk object itself.

Let’s see an example below:

package org.kodejava.itextpdf;

import com.itextpdf.text.*;
import com.itextpdf.text.pdf.PdfWriter;

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

public class PhraseCustomizeDemo {
    public static void main(String[] args) {
        Document document = new Document();

        try {
            PdfWriter.getInstance(document,
                    new FileOutputStream("PhraseCustomizeDemo.pdf"));
            document.open();

            // Creates a phrase object, sets leading to 32 and
            // adds some chunks.
            Phrase phrase1 = new Phrase(20);

            // Set main font information of the Phrase object.
            phrase1.setFont(FontFactory.getFont(FontFactory.COURIER, 12,
                    Font.BOLD, new BaseColor(0, 0, 255)));

            for (int i = 0; i < 50; i++) {
                phrase1.add(new Chunk("Hello "));
            }

            // Add chunk to the phrase and replace the font information
            // for this chunk.
            phrase1.add(new Chunk("Hello",
                    FontFactory.getFont(FontFactory.HELVETICA)));
            document.add(phrase1);

            // Creates a phrase by defining the leading and a string.
            Phrase phrase2 = new Phrase(40, "Hello World!!!");
            document.add(phrase2);

            // Creates a phrase by defining the leading and add a chunk
            // into the phrase. The chunk has it own font face, font
            // style and color.
            Phrase phrase3 = new Phrase(50,
                    new Chunk("Hello I am BIG", FontFactory.getFont(
                            FontFactory.HELVETICA, 40,
                            Font.ITALIC, new BaseColor(255, 0, 0))));
            document.add(phrase3);
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        } finally {
            document.close();
        }
    }
}

How do I use iText Phrase class?

By I Wayan Saryada in iText PDF 0 Comment

The com.itextpdf.text.Phrase represent a phrase of text in the Document object. The Phrase object knows how to add spacing between lines of text. So if we add some phrase into the document it will start on a new line when it reaches the right edge of the document. The default leading / line spacing of a Phrase object is 16.

package org.kodejava.itextpdf;

import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Phrase;
import com.itextpdf.text.pdf.PdfWriter;

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

public class PhraseDemo {
    public static void main(String[] args) {
        // Creates an instance of Document.
        Document document = new Document();
        try {
            // Write the pdf document into a file using the PdfWriter
            // and passes the document object and a FileOutputStream.
            PdfWriter.getInstance(document, new FileOutputStream("PhraseDemo.pdf"));
            document.open();

            // Add a some Phrase element into the document.
            document.add(new Phrase("This is the first text "));
            document.add(new Phrase("This is the second text "));
            document.add(new Phrase("This is the third text "));
            document.add(new Phrase("This is the fourth text "));
            document.add(new Phrase("This is the fifth text "));
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        } finally {
            document.close();
        }
    }
}
