public class BackgroundColor {
    public static void main(String[] args) {
        //Load PDF file
        PdfDocument doc = new PdfDocument();
        doc.loadFromFile("D:\\Desktop\\Sample.pdf");

        PdfPageBase page;
        int pageCount = doc.getPages().getCount();

        //Set Background color
        for(int i = 0; i < pageCount; i ++) {
            page = doc.getPages().get(i);
            page.setBackgroundColor(Color.yellow);
