Add Header to PDF

Add header to PDF

Use PdfFileStamp when you need repeated header content on each page.

Steps

1. Create a PdfFileStamp instance and bind the source PDF.
2. Build the header content as FormattedText or load it from an image stream.
3. Call the appropriate addHeader overload.
4. Save the output and close the facade object.

Java examples

public static void addTextHeader(Path inputFile, Path outputFile) {
    PdfFileStamp pdfStamper = new PdfFileStamp();
    try {
        pdfStamper.bindPdf(inputFile.toString());
        FormattedText text = new FormattedText("Sample Header");
        pdfStamper.addHeader(text, 20);
        pdfStamper.save(outputFile.toString());
    } finally {
        pdfStamper.close();
    }
}

public static void addImageHeader(Path inputFile, Path imageFile, Path outputFile) throws Exception {
    PdfFileStamp pdfStamper = new PdfFileStamp();
    try (InputStream imageStream = Files.newInputStream(imageFile)) {
        pdfStamper.bindPdf(inputFile.toString());
        pdfStamper.addHeader(imageStream, 20);
        pdfStamper.save(outputFile.toString());
    } finally {
        pdfStamper.close();
    }
}

public static void addHeaderWithMargins(Path inputFile, Path outputFile) {
    PdfFileStamp pdfStamper = new PdfFileStamp();
    try {
        pdfStamper.bindPdf(inputFile.toString());
        FormattedText text = new FormattedText(
                "Sample Header",
                Color.BLUE,
                FontStyle.Helvetica,
                EncodingType.Winansi,
                true,
                12.0f);
        pdfStamper.addHeader(text, 20, 20, 20);
        pdfStamper.save(outputFile.toString());
    } finally {
        pdfStamper.close();
    }
