\fill[black, path fading=west] (current page.south west) rectangle (current page.north east);
\end{tikzpicture}

代码的第一部分产生了正确的图像：

在此处输入图片描述

而第二段代码却没有：

在此处输入图片描述

而不是遮蔽整个页面，

  1. 它只遮住下半部分，
  2. 它没有遮挡最右边的内容
  3. 并且在此过程中它会改变页面大小。

我该如何正确地做到这一点，即遮蔽正确的区域而不改变页面的尺寸？

您可能只对图片进行阴影处理。如果您移除，border=4pt则整个图片都会被阴影覆盖。
