Create Rubber Stamp With Appearance Stream

Rubber stamp annotations can be customized using an external image file. Instead of relying only on text-based stamps, you can define a visual appearance (for example, a company logo or approval badge) and place it on a page.

1. Create a PdfContentEditor instance.
2. Bind the input PDF document.
3. Define a rectangle for the stamp location.
4. Use an image file as the stamp appearance.
5. Apply text and color settings.
6. Save the updated PDF document.

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 create_rubber_stamp_with_appearance_file(infile, image_file, outfile):
    # Create PdfContentEditor object
    content_editor = pdf_facades.PdfContentEditor()
    # Bind document to PdfContentEditor
    content_editor.bind_pdf(infile)
    # Create rubber stamp using appearance_file overload (image path)
    content_editor.create_rubber_stamp(
        1,
        apd.Rectangle(100, 400, 200, 60),
        "Stamp with custom appearance",
        apd.Color.dark_green,
        image_file,
    )
    # Save updated document
    content_editor.save(outfile)
