按 ID 删除印章

在处理包含多个印章的 PDF 时，通常需要在不影响其他印章的情况下删除特定印章。使用基于 ID 的删除，您可以精准控制要删除的印章：

• ‘delete_stamp_by_id(stamp_id, page_number)’ – 删除特定页面上按其 ID 的单个印章
• ‘delete_stamp_by_ids(page_number, stamp_ids)’ – 删除给定页面上按其 ID 的多个印章

1. 创建一个 PdfContentEditor 实例。
2. 绑定输入的 PDF 文档。
3. 添加两个具有不同 ID 的橡皮图章。
4. 使用单 ID 和多 ID 删除方法删除图章。
5. 保存更新后的 PDF。

    # Delete by single ID overload and by IDs overload

    content_editor.delete_stamp_by_ids(1, [2])

    # Save updated document
    content_editor.save(outfile)
