Gunakan PdfFileStamp ketika penomoran halaman harus diterapkan setelah konten PDF sudah dibuat.

Langkah

2. Pilih strategi penempatan nomor halaman yang Anda butuhkan.
3. Opsional, atur gaya penomoran dan nomor awal sebelum stamping.
4. Panggil addPageNumber dengan overload yang diperlukan.
5. Simpan output dan tutup objek fasad.

Contoh Java

public static void addPageNumbersDefault(Path inputFile, Path outputFile) {
    PdfFileStamp pdfStamper = new PdfFileStamp();
    try {
        pdfStamper.bindPdf(inputFile.toString());
        pdfStamper.addPageNumber("Page #");
        pdfStamper.save(outputFile.toString());
    } finally {
        pdfStamper.close();
    }
}

public static void addPageNumbersAtCoordinates(Path inputFile, Path outputFile) {
    PdfFileStamp pdfStamper = new PdfFileStamp();
    try {
        pdfStamper.bindPdf(inputFile.toString());
        pdfStamper.addPageNumber("Page #", 300, 20);
        pdfStamper.save(outputFile.toString());
    } finally {
        pdfStamper.close();
    }
}

public static void addPageNumbersWithPositionAndMargins(Path inputFile, Path outputFile) {
    PdfFileStamp pdfStamper = new PdfFileStamp();
    try {
        pdfStamper.bindPdf(inputFile.toString());
        pdfStamper.addPageNumber("Page #", PdfFileStamp.POS_BOTTOM_RIGHT, 10, 10, 10, 10);
        pdfStamper.save(outputFile.toString());
    } finally {
        pdfStamper.close();
    }
}

public static void addPageNumbersWithRomanStyle(Path inputFile, Path outputFile) {
    PdfFileStamp pdfStamper = new PdfFileStamp();
    try {
        pdfStamper.bindPdf(inputFile.toString());
        pdfStamper.setNumberingStyle(NumberingStyle.NumeralsRomanUppercase);
        pdfStamper.setStartingNumber(42);
        pdfStamper.addPageNumber("Page #", PdfFileStamp.POS_UPPER_RIGHT);
        pdfStamper.save(outputFile.toString());
    } finally {
        pdfStamper.close();
    }
