How do I create an underlined or strike through chunk in iText?

By Wayan in iText PDF 2 Comments

You can use the Chunk‘s setUnderline(float thickness, float yPosition) method to add underline or strike through to a chunk. A negative value to the yPosition create an underline while a positive value will produce a strike through.

package org.kodejava.itextpdf;

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

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

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

            // Creates a chunk with an underline with 0.1 thickness
            Chunk underline = new Chunk("The quick brown fox ");
            underline.setUnderline(0.1f, -1f);
            doc.add(underline);

            // Creates a strike through chunk with 1 thickness
            Chunk strike = new Chunk("jumps over the lazy dog.");
            strike.setUnderline(1f, 3f);
            doc.add(strike);
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        } finally {
            doc.close();
        }
    }
}

How do I define a font for text object in iText?

By Wayan in iText PDF 0 Comment

We can set font style for text object such as Chunk, Phrase, Paragraph, etc. using the com.itextpdf.text.Font class. We can define the font face, size, style and its color using this class.

package org.kodejava.itextpdf;

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

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

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

            // Creates some fonts
            Font largeBold = new Font(Font.FontFamily.COURIER, 32,
                    Font.BOLD);
            Font smallItalic = new Font(Font.FontFamily.HELVETICA, 10,
                    Font.ITALIC);
            Font redFont = new Font(Font.FontFamily.TIMES_ROMAN, 12,
                    Font.ITALIC | Font.UNDERLINE, BaseColor.RED);

            // Creates chunk, phrase and paragraph with font
            // information.
            Chunk chunk = new Chunk("Hello World", largeBold);
            Phrase phrase =
                    new Phrase("The quick brown fox ", smallItalic);
            Paragraph paragraph =
                    new Paragraph("jumps over the lazy dog", redFont);

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

How do I create super / subscript in iText?

By Wayan in iText PDF 0 Comment

The following example you’ll see how to create a superscript and subscript text in the pdf document using iText. We can use the Chunk‘s class method called setTextRise(). A positive value will create a superscript text while a negative value will create a subscript text.

package org.kodejava.itextpdf;

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

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

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

            Font small = FontFactory.getFont(FontFactory.HELVETICA, 5, Font.ITALIC);

            // Add some chunks into the doc object.
            doc.add(new Chunk("The quick brown  "));

            Chunk superscript = new Chunk("fox ");
            superscript.setTextRise(5f);
            superscript.setFont(small);
            doc.add(superscript);

            doc.add(new Chunk("jumps over the lazy "));

            Chunk subscript = new Chunk("dog");
            subscript.setTextRise(-5f);
            subscript.setFont(small);
            doc.add(subscript);
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        } finally {
            doc.close();
        }
    }
}

How do I rotate image in iText PDF document?

By Wayan in iText PDF 2 Comments

You can rotate images in the iText pdf document using the setRotation(final float r) or the setRotationDegrees(final float deg) methods of the com.itextpdf.text.Image class. This method sets the rotation in radian and in degree respectively. Let’s see an example below:

package org.kodejava.itextpdf;

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

import java.io.FileOutputStream;
import java.io.IOException;

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

            // Rotate image in radian using the setRotation method.
            String filename = "kodejava-itextpdf/src/main/resources/java.png";
            Image image = Image.getInstance(filename);
            image.setRotation(90f);
            doc.add(image);

            // The following line to prevent the "Server returned
            // HTTP response code: 403" error.
            System.setProperty("http.agent", "Chrome");

            // Rotate image in degree using the setRotationDegree method
            String url = "https://kodejava.org/wp-content/uploads/2017/01/kodejava.png";
            image = Image.getInstance(url);
            image.setRotationDegrees(90);
            doc.add(image);
        } catch (DocumentException | IOException e) {
            e.printStackTrace();
        } finally {
            doc.close();
        }
    }
}

How do I scale an image in PDF document using iText?

By Wayan in iText PDF 1 Comment

The com.itextpdf.text.Image class represent an image of a graphic element such as JPEG, PNG or GIF that can be inserted into a PDF document. There are some methods of the com.itextpdf.text.Image class that can be used to scale the image. These methods include the following: scaleAbsolute(), scaleAbsoluteHeight(), scaleAbsoluteWidth(), scalePercent() and scaleToFit().

These are signatures of those APIs:

  • scaleAbsolute(float newWidth, fload newHeight) – Scales the image to an absolute width and an absolute height.
  • scaleAbsoluteHeight(float newHeight) – Scales the image to an absolute height.
  • scaleAbsoluteWidht(float newWidth) – Scales the image to an absolute width.
  • scalePercent(float percent) – Scales the image to a certain percentage.
  • scalePercent(float percentX, float percentY) – Scales the image to a certain percentage of width and height.
  • scaleToFit(float fitWidth, float fitHeight) – Scales the image to fit a certain width and height.

Here is a code snippet that shows how to use the scaleAbsolute(), scalePercent() and scaleToFit() methods.

package org.kodejava.itextpdf;

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

import java.io.FileOutputStream;
import java.io.IOException;

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

            // Scale the image to an absolute width and an absolute
            // height
            String filename = "kodejava-itextpdf/src/main/resources/java.png";
            Image image = Image.getInstance(filename);
            image.scaleAbsolute(200f, 200f);
            doc.add(image);

            // The following line to prevent the "Server returned
            // HTTP response code: 403" error.
            System.setProperty("http.agent", "Chrome");

            // Scale the image to a certain percentage
            String url = "https://kodejava.org/wp-content/uploads/2017/01/kodejava.png";
            image = Image.getInstance(url);
            image.scalePercent(200f);
            doc.add(image);

            // Scales the image so that it fits a certain width and
            // height
            image = Image.getInstance(url);
            image.scaleToFit(100f, 200f);
            doc.add(image);
        } catch (DocumentException | IOException e) {
            e.printStackTrace();
        } finally {
            doc.close();
        }
    }
