我正在对 PDF 进行注释，我想更改它的颜色。我被引导到这个有用的链接：https ://pymupdf.readthedocs.io/en/latest/faq.html#how-to-add-and-modify-annotations
我使用了链接中的代码：
# -*- coding: utf-8 -*-
"""
-------------------------------------------------------------------------------
Demo script showing how annotations can be added to a PDF using PyMuPDF.
It contains the following annotation types:
Caret, Text, FreeText, text markers (underline, strike-out, highlight,
squiggle), Circle, Square, Line, PolyLine, Polygon, FileAttachment, Stamp
and Redaction.
There is some effort to vary appearances by adding colors, line ends,
opacity, rotation, dashed lines, etc.
Dependencies
------------
PyMuPDF v1.17.0

我一直遇到这个错误：
AttributeError: 'Document' object has no attribute 'new_page'
我已经在其他一些 PDF 上尝试过，但它似乎不起作用，但是，PYMUDF 文档https://pymupdf.readthedocs.io/en/latest/document.html#Document.new_page描述它应该有这个属性.
如何启用要插入的新页面以消除此错误？
