问题描述
我正在对 PDF 进行注释，我想更改其颜色。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

"""
-------------------------------------------------------------------------------
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 上尝试过它，但它似乎不起作用，但是，PYMUDF 文档 https://pymupdf.readthedocs.io/en/latest/document.html#Document.new_page 描述它应该具有此属性。
解决方法
他们似乎将其命名为 _newPage()。该文档还指出了一个名为 insert_page() 的方法，该方法也不存在。文档似乎与最新版本不同步。
