package com.aspose.pdf.examples;

import com.aspose.pdf.Color;
import com.aspose.pdf.Document;
import com.aspose.pdf.FontRepository;
import com.aspose.pdf.FontStyles;
import com.aspose.pdf.HorizontalAlignment;
import com.aspose.pdf.PageNumberStamp;

public class ExampleDeleteImages {

    private static String _dataDir = "/home/admin1/pdf-examples/Samples/";

    public static void ExampleAddPageNumber() {

        // Open document
        Document pdfDocument = new Document(_dataDir + "PageNumberStamp.pdf");

        // Create page number stamp
        PageNumberStamp pageNumberStamp = new PageNumberStamp();

        // Whether the stamp is background
        pageNumberStamp.setBackground(false);
        pageNumberStamp.setFormat("Page # of " + pdfDocument.getPages().size());
        pageNumberStamp.setBottomMargin (10);
        pageNumberStamp.setHorizontalAlignment ( HorizontalAlignment.Center);
        pageNumberStamp.setStartingNumber(1);
        // Set text properties
        pageNumberStamp.getTextState().setFont (FontRepository.findFont("Arial"));
        pageNumberStamp.getTextState().setFontSize (14.0F);
        pageNumberStamp.getTextState().setFontStyle (FontStyles.Bold);        
        pageNumberStamp.getTextState().setForegroundColor (Color.getAqua());

        // Add stamp to particular page
        pdfDocument.getPages().get_Item(1).addStamp(pageNumberStamp);

        _dataDir = _dataDir + "PageNumberStamp_out.pdf";
        // Save output document
        pdfDocument.save(_dataDir);

    }
