全局删除印章

在处理多页文档时，您可能需要在整个文档中删除某些印章。‘delete_stamp_by_id()’ 和 ‘delete_stamp_by_ids()’ 方法允许您通过标识符全局删除印章，无需手动遍历每一页。

1. 创建一个 PdfContentEditor 实例。
2. 绑定输入的 PDF 文档。
3. 在多个页面上添加橡胶印章。
4. 使用其 ID 全局删除印章。
5. 保存更新后的 PDF 文档。

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

from config import set_license, initialize_data_dir


def delete_stamps_globally(infile, outfile):
    # Create PdfContentEditor object
    content_editor = pdf_facades.PdfContentEditor()
    # Bind document to PdfContentEditor
    content_editor.bind_pdf(infile)

    # Add stamps across multiple pages so global deletion is meaningful
    for page in range(1, 5):
        content_editor.create_rubber_stamp(
            page,
            apd.Rectangle(120, 500, 180, 60),
            "Draft",
            "Stamp for global deletion",
            apd.Color.gray,
        )

    # delete_stamp_by_id without page number removes stamp ID from all pages
    content_editor.delete_stamp_by_id(1)
    # delete_stamp_by_ids without page number removes a list of IDs from all pages
    content_editor.delete_stamp_by_ids([2, 3])

    # Save updated document
    content_editor.save(outfile)
