for (PdfXObject xObject : doc.getPages().get_Item(0).getXObjects())
{
    if (xObject.getText().contains("Test"))
    {
        xObject.setText("Passed");
    }

PdfDocument doc = Document.load(PdfDocument.class, "D:\\xobjects.pdf");

for (PdfXObject xObject : doc.getPages().get_Item(0).getXObjects())
{
    if (xObject.getText().contains("Test"))
    {
        xObject.getFormattedTextFragments().clear();
        xObject.getFormattedTextFragments().add("Passed", new Font("Calibri", 19, FontStyle.Bold), Color.getRed(), Color.getAqua());

    if (artifact.getText().contains("Test"))
    {
        artifact.getFormattedTextFragments().clear();
        artifact.getFormattedTextFragments().add("Passed", new Font("Calibri", 19, FontStyle.Bold), Color.getRed(), Color.getAqua());
    }

    }
}

doc.save("D:\\output.pdf");

String imagePath = "D:\\test.png";
File imageFile = new File(imagePath);
byte[] imageBytes = new byte[(int)imageFile.length()];
InputStream imageInputStream = new FileInputStream(imageFile);
imageInputStream.read(imageBytes);
imageInputStream.close();
