我在使用 Adjustbox 编写 LaTeX 代码时遇到了一个奇怪的问题。我目前正在使用 RMarkdown，它将 Markdown 转换为 LaTeX 代码，但无法缩小导致问题的范围。我认为显示.tex是最相关的，但为了以防万一，还是包括 RMarkdown。

这是我的 RMarkdown 代码：

最小化示例并删除不需要的包总是有帮助的。一个较小的示例是

如果你删除
\setkeys{Gin}{width=\maxwidth,height=\maxheight,keepaspectratio}
然后你得到
如果您全局设置键，则必须确保没有其他东西使用这些值。（我不确定为什么adjustbox在这里使用Gin键系列，但是......）
答案2
按照 David 的建议注释掉（或删除）代码，这很好，但可能会导致 RMarkdown（Quarto）中其他图形的格式被破坏。
相反，使用Gin以下代码覆盖 pandoc 模板代码的一部分
\setkeys{Gin}{width=\linewidth,height=\textheight,keepaspectratio}
是一个更稳定的解决方案。（通过放入 YAML 标头，例如include-in-header:在 Quarto 中）
