我正在使用包 tcolorbox 创建一个包含示例 Latex 的文件，我已经查看了 tcblisting 环境选项并使用了这些：
- 列表外的文本
- 列出外部文本
- 列出上面的文字
- 列表上方的文字
但有时我想展示的示例并不符合我的期望，于是我就有了疑问：您可以使用选项来添加图形而不是格式化的文本吗？类似于“showexpl”包中的“graphic”选项。问候，Pablo 编辑：像这样
答案1
从 开始tcolorbox version 2.71 (2014/02/21)，所有缺失的comment outside listingea 选项都已实现。评论可以视为任何东西，尤其是图片。对于图片，有一个新选项image comment，可以简单地将图片设置为评论。
A评论 外部（tcolorbox左/右/下/上）始终被视为降低框内容的一部分。因此，在下面的例子中，center lower将位于列表上方的图片置于中心。
\documentclass{article}
\usepackage[most]{tcolorbox}
\newtcblisting{mylisting}[1]{%
colback=red!5!white,colframe=red!75!black,
image comment={width=2.5cm}{example-image-a.pdf},
#1}
\begin{document}

\section{image above listing}
\begin{mylisting}{comment above listing,center lower}

重要提示
据软件包作者称，自 2.71 版起tcolorbox，列表和的代码更改了几个内部命令。用户界面保持不变，但下面带有内部宏的示例代码可能不再起作用。无论如何，从 2.71 版开始，下面的命令不再需要，因为缺少的选项已合并到软件包中。
在下面的示例代码中，我定义了四个新选项，允许插入与某些列表相对应的现有图像；这四个选项是
listing above image
image above listing
listing outside image
image outside listing
第一个是将代码放在图像上方；第二个是将图像放在代码上方；第三个和第四个是将代码与图像并排放置（列表在右边，图像在左边，反之亦然）。
该\tcbuselistingimage命令用于声明图像；可选参数将传递给 的可选参数\includegraphics，强制参数接收图像文件的名称。
代码：
