Add multiple images into a single pdf file with iText using java

I have the following code but this code add only the last image into pdf.

    try {
        filePath = (filePath != null && filePath.endsWith(".pdf")) ? filePath
                : filePath + ".pdf";
        Document document = new Document();
        PdfWriter writer = PdfWriter.getInstance(document,
                new FileOutputStream(filePath));
        document.open();    
        // document.add(new Paragraph("Image Example"));
        for (String imageIpath : imagePathsList) {

            // Add Image
            Image image1 = Image.getInstance(imageIpath);
            // Fixed Positioning
            image1.setAbsolutePosition(10f, 10f);
            // Scale to new height and new width of image
            image1.scaleAbsolute(600, 800);
            // image1.scalePercent(0.5f);
            // Add to document
            document.add(image1);
            //document.bottom();


        }
        writer.close();

    } catch (Exception e) {
        LOGGER.error(e.getMessage());
    }

Would you give me a hint about how to update the code in order to add all the images into the exported pdf? imagePathsList contains all the paths of images that that I want to add into a single pdf.
