LaTeX 不允许我添加两个背景图

我正在用 LaTeX 写一本书。我想在每个“Part_X”首页和每个“Chapter_X”首页后面放置一个填满页面的 .png 图片。每个部分和章节的填满页面的 .png 图片都不同。以下是它应该是什么样子的示例：

在此处输入图片描述

下面是一些简化的 LaTeX 代码，应将其放在'testFig_01.png'“Part_1”首页和'testFig_02.png'“Chapter_01”首页后面：

不幸的是，上面显示的 LaTeX 代码只将'testFig_01'“Part_1”放在了首页后面，而没有将'testFig_02'“Chapter_01”放在首页后面。奇怪的是，我注意到注释掉放在'testFig_01'“Part_01”后面的代码将允许'testFig_02'将其绘制在“Chapter_01”后面：

% COMMENTED OUT:

看起来 LaTeX 不允许我\ThisCenterWallPaper{..}多次使用该命令将背景图像放入文档中。我该怎么办？

答案1

删除修补的行\@endpart。您不需要不透明的白色页面颜色。然后，您就可以使用代码获得所需的结果。

这是另一个建议。在下面的例子中，所有部分页面都获得由设置的背景图像\setpartbackgroundimage{<image>}。要更改图像，请在之前使用此命令\part。要获取没有图像的部分页面，只需使用空参数。

如果章节页面需要获取背景图像，请使用\chapterbackgroundimage{<image>}after \chapter。

\usepackage{xpatch}
\newcommand\partbackgroundimage{}
\newcommand\setpartbackgroundimage[1]{\renewcommand\partbackgroundimage{#1}}
    \xpatchcmd{\part}{\thispagestyle{plain}}
      {\ifdefempty{\partbackgroundimage}{}{\ThisCenterWallPaper{1}{\partbackgroundimage}}%
        \thispagestyle{plain}}{}{}

\newcommand\chapterbackgroundimage[1]{\ThisCenterWallPaper{1}{#1}\clearpage}
