将印章添加到 PDF

Aspose.PDF for Python via .NET 提供了 PdfFileStamp 用于向 PDF 页面添加重复内容的外观。除页眉、页脚和页码外，您还可以使用它在文档的每一页上放置基于文本的印章。

将印章添加到 PDF

在配置印章后，将输入 PDF 绑定到 PdfFileStamp, 添加印章，并保存输出文件。这将在整个文档中应用配置的印章。

import sys
from os import path

import aspose.pdf.facades as pdf_facades

CURRENT_DIR = path.dirname(__file__)
EXAMPLES_DIR = path.abspath(path.join(CURRENT_DIR, "..", ".."))
if EXAMPLES_DIR not in sys.path:
    sys.path.insert(0, EXAMPLES_DIR)

from config import initialize_data_dir, set_license


def add_stamp_to_pdf(infile: str, image_file: str, outfile: str) -> None:
    """Add an image stamp to a PDF file."""
    pdf_stamper = pdf_facades.PdfFileStamp()
    try:
        pdf_stamper.bind_pdf(infile)

        stamp = pdf_facades.Stamp()
        stamp.bind_image(image_file)

        pdf_stamper.add_stamp(stamp)
        pdf_stamper.save(outfile)
    finally:
        pdf_stamper.close()
