Stamping New Content

Developers may edit any PDF document by adding new content to any page (or pages) using the StampHTML method for PDF management.

Below is an example of how you can use the StampHTML method in a Python script:

# Import the required libraries
from pdf_toolkit import PDFManager  # Assuming 'pdf_toolkit' is a hypothetical library

def stamp_html_on_pdf(input_pdf_path, output_pdf_path, html_content, page_numbers):
    """
    Stamps HTML content onto specified pages of a PDF document.

    Parameters:
    input_pdf_path (str): The path to the original PDF document.
    output_pdf_path (str): The path where the modified PDF document will be saved.
    html_content (str): The HTML content to be added to the PDF.
    page_numbers (list of int): The list of page numbers on which the HTML is to be stamped.

    Returns:
    None
    """
    # Initialize the PDF Manager
    pdf_manager = PDFManager(input_pdf_path)

    # Iterate over each specified page
    for page_number in page_numbers:
        # Add the HTML content to the current page
        pdf_manager.stamp_html(page_number, html_content)

    # Save the modified PDF document to the specified path
    pdf_manager.save(output_pdf_path)

# Example usage of the function
if __name__ == "__main__":
    input_pdf = "example.pdf"
    output_pdf = "stamped_example.pdf"
    html_content = "<h1>This is a header</h1><p>This is a paragraph.</p>"
    pages_to_stamp = [1, 2, 3]  # Specify pages you want to modify

    # Call the function to stamp the HTML content onto the specified pages
    stamp_html_on_pdf(input_pdf, output_pdf, html_content, pages_to_stamp)

# Import the required libraries
from pdf_toolkit import PDFManager  # Assuming 'pdf_toolkit' is a hypothetical library

def stamp_html_on_pdf(input_pdf_path, output_pdf_path, html_content, page_numbers):
    """
    Stamps HTML content onto specified pages of a PDF document.

    Parameters:
    input_pdf_path (str): The path to the original PDF document.
    output_pdf_path (str): The path where the modified PDF document will be saved.
    html_content (str): The HTML content to be added to the PDF.
    page_numbers (list of int): The list of page numbers on which the HTML is to be stamped.

    Returns:
    None
    """
    # Initialize the PDF Manager
    pdf_manager = PDFManager(input_pdf_path)

    # Iterate over each specified page
    for page_number in page_numbers:
        # Add the HTML content to the current page
        pdf_manager.stamp_html(page_number, html_content)

    # Save the modified PDF document to the specified path
    pdf_manager.save(output_pdf_path)

# Example usage of the function
if __name__ == "__main__":
    input_pdf = "example.pdf"
    output_pdf = "stamped_example.pdf"
    html_content = "<h1>This is a header</h1><p>This is a paragraph.</p>"
    pages_to_stamp = [1, 2, 3]  # Specify pages you want to modify

    # Call the function to stamp the HTML content onto the specified pages
    stamp_html_on_pdf(input_pdf, output_pdf, html_content, pages_to_stamp)

Key Points:

• PDFManager Class: The class used to manage PDF documents, providing methods like stamp_html to manipulate pages.
• Parameters: The stamp_html_on_pdf function accepts paths for input and output PDFs, the HTML content to be stamped, and the list of page numbers that need modification.
• Functionality: The function iterates over the specified pages and stamps the given HTML content on each one, saving the result to a new PDF file.
• Assumptions: The example assumes the existence of a pdf_toolkit library and a PDFManager class with specific methods, which are hypothetical in this context.

Before using this script, ensure you have the right dependencies and understand the library being utilized.
