Convert jpg to pdf using iText Library

During automation, I came across a scenario where I have to share the screenshots of all the failed test cases along with the Test Report.

Isn’t it a feasible way to send a pdf file containing screenshots of failed test cases instead of sending each screenshot separately over an email?

HOW TO CREATE A PDF FILE?

We can achieve this task by using the iTextPdf Library. You can get the dependency from here.

Add the following dependency in your pom.xml file.

<!-- https://mvnrepository.com/artifact/com.itextpdf/itextpdf -->
<dependency>
   <groupId>com.itextpdf</groupId>
   <artifactId>itextpdf</artifactId>
   <version>5.5.13.2</version>
</dependency>

Here are the lines of code:

/**
 * Method to create a PDF containing all the screenshots of failed test cases.
 */
public void createPDF()
{
    try
    {
        //Setting up the font
        Font f=new Font(Font.FontFamily.TIMES_ROMAN,50.0f,Font.BOLD, BaseColor.BLUE);
        //Get all the screenshots
        List<File> imagesList = getFiles(USER_DIRECTORY + "/screenshots");
        Image im = Image.getInstance(imagesList.get(0).getAbsolutePath());
        im.setAbsolutePosition(0,0);

        Document doc = new Document(im);
        //Check for the reports folder
        File folder = new File(USER_DIRECTORY + "/reports");
        if(!folder.exists())
            folder.mkdir();

        //Write content in the PDF
        PdfWriter.getInstance(doc, new FileOutputStream(USER_DIRECTORY + "/reports/results.pdf"));
        doc.open();
        doc.addTitle("Failed Cases Screenshots");
        doc.addAuthor("Ruchi");
        for (File file : imagesList)
        {
            Paragraph para = new Paragraph(file.getName(), f);
            para.setAlignment(Element.ALIGN_RIGHT);
            im = Image.getInstance(file.getAbsolutePath());
            doc.newPage();
            im.setAbsolutePosition(0,0);
            doc.add(para);
            doc.add(im);
        }
        doc.close();
    }
    catch (Exception exception)
    {
        exception.printStackTrace();
    }
}

That’s it! Your pdf is ready.
