大树适合页面

我正在尝试为井字游戏绘制一棵树。树的输出会相当大，我希望页面能够随着树的生长以适当的间距自动缩放树的大小。这可能吗？

  • 而不是qtree使用forest包
  • 画的是“tictactoe”的小符号
  • 对于“tictactoe”使用tabularray 表格
  • 图像未缩放
  • 使用该geometry包可以扩大文本区域

经过这些修改后，代码中以 标记% <---，结果仍然易于阅读：

答案2

使用调整框（自动调整图形以横跨页面\textwidth）并稍微修改\tictactoe命令，您就可以实现想要的效果。如果您不喜欢这种方法，那么您可以将生成的图形旋转 90 度以横跨页面的垂直空间。
