Itext document to match image size

I am trying to add image to pdf using iText with A4 page properties:

com.itextpdf.text.Document document = new com.itextpdf.text.Document(
                com.itextpdf.text.PageSize.A4);
        PdfWriter.getInstance(document, new FileOutputStream(m_pathToCreateFileIn + "my_web.pdf"));
        System.out.println("New pdf -> " + m_pathToCreateFileIn + "my_web.pdf");
        document.open();
        Image image = Image.getInstance(pngPath);
        image.scaleToFit(com.itextpdf.text.PageSize.A4.getWidth(), com.itextpdf.text.PageSize.A4.getHeight());
        document.add(image);

I set both document and Image to A4 page size and still the image does not fit my document page size.

Thank you for any help.

I know this is super late to the party, but I wanted to extend on the answer from @DonKanallie a bit (which was super helpful btw) to be a bit more flexibly in dealing with images of different sizes/dimensions. As the original poster mentioned, my Image was not fitting properly in an A4 output, hence the size of the image taken into consideration and the custom rectangle below

        Document document = new Document();
        FileOutputStream fos = new FileOutputStream(outputPath);            
        Image image = Image.getInstance(inputFile);
        //Get Size of Original Image for conversion
        float origWidth = image.getWidth();
        float origHeight = image.getHeight();
        image.scaleToFit(origWidth,origHeight);
        //Set position of image in top left corner
        image.setAbsolutePosition(0,0);
        //Create Rectangle in support of new page size
        Rectangle rectangle = new Rectangle(origWidth,origHeight);
        PdfWriter writer = PdfWriter.getInstance(document, fos);
        writer.open();
        document.open();
        //Set page size before adding new page
        document.setPageSize(rectangle);
        document.newPage();
        document.add(image);
        document.close();
        writer.close();

You have to add document.newPage() before your changes will take effect, because you can't change the current page. Try:

    Document document = new Document();
    PdfWriter.getInstance(document, new FileOutputStream(m_pathToCreateFileIn + "my_web.pdf"));
    document.open();
    Image image = Image.getInstance(pngPath);
    image.scaleToFit(PageSize.A4);
    document.setPageSize(PageSize.A4);
    document.newPage();
    document.add(image);
    document.close();

Try to adjust parameters by x and y axis using this methods.

  String imageUrl1 = "";
  Image image1 = Image.getInstance(new URL(imageUrl1));
  image1.scaleAbsolute(140, 190);
  image1.setAbsolutePosition(450, 580);
  document.add(image1);
