Add Margins to PDF Pages

Adding margins to PDF pages can enhance readability, prepare documents for printing, or allocate space for annotations. Using Aspose.PDF for Python, developers can programmatically add margins to specific pages of a PDF without modifying the content layout.

In this code snippet, the PdfFileEditor class is used to add 0.5-inch margins to pages 1 and 3 of the input document. The margins are defined in points (1 inch = 72 points) and applied individually to the left, right, top, and bottom of each page.

1. Open the source PDF document.
2. Create a ‘PdfFileEditor’ instance.
3. Define the margins and pages to modify.
4. Apply margins using the ‘add_margins’ method.
5. Save the updated PDF to the output file.

from io import FileIO
import sys
from os import path
import aspose.pdf as ap
import aspose.pdf.facades as pdf_facades

sys.path.append(path.join(path.dirname(__file__), ".."))

from config import set_license, initialize_data_dir


# Add Margins to PDF Pages
def add_margins_to_pdf_pages(infile, outfile):
    # Create a PdfFileEditor object
    pdf_editor = pdf_facades.PdfFileEditor()
    # Define the margins to be added (in points)
    left_margin = 36  # 0.5 inch
    right_margin = 36  # 0.5 inch
    top_margin = 36  # 0.5 inch
    bottom_margin = 36  # 0.5 inch

    pdf_editor.add_margins(
        infile, outfile, [1, 3], left_margin, right_margin, top_margin, bottom_margin
    )
