List Stamps

When working with annotated PDFs, you may need to inspect existing rubber stamps before modifying or removing them. The ‘get_stamps()’ method allows you to retrieve all stamps placed on a particular page. You can then iterate through the results and process them programmatically.

1. Create a PdfContentEditor instance.
2. Bind the input PDF document.
3. Retrieve all stamps from page 1.
4. Iterate through the stamp collection.
5. Print each stamp.
6. Display a message if no stamps exist.

import aspose.pdf.facades as pdf_facades
import aspose.pydrawing as apd
from io import BytesIO
import sys
from os import path

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

from config import set_license, initialize_data_dir


def list_stamps(infile):
    # Create PdfContentEditor object
    content_editor = pdf_facades.PdfContentEditor()
    # Bind document to PdfContentEditor
    content_editor.bind_pdf(infile)
    # List all stamps on page 1
    stamps = content_editor.get_stamps(1)

    count = 0
    for stamp in stamps:
        count += 1
        print(f"Stamp {count}: {stamp}")

    if count == 0:
        print("No stamps found")
