如何在横向模式下生成 tikz 图形？我试图制作一个独立的图形，因为我不会将其包含在文档或文章中。这个解决方案似乎不适用于我的情况：在横向模式下使用 TikZ？。我尝试使用\usepackage[landscape]{geometry}和\usepackage{pdflscape}和\usepackage[pdftex]{lscape}；但似乎都不起作用。我在编译时收到此错误消息：
！缺少 \endgroup 插入。\endgroup l.10 \begin{landscape}
当我移除它时begin{landscape}，end{landscape}我就只剩下一个常规的纵向方向来切断我的身影。
