无法使用 \fontsize 增加 tikz 文本的字体大小

Question

您面临的问题在于您使用 Ti 定义的图片钾Z 很大，您尝试使用缩小它，\resizebox这也会减小字体大小。您尝试通过增加字体大小来抵消此行为。但是，LaTeX 不允许您任意增加字体大小。

解决这个问题的最好方法是用 Ti 创建绘图钾Z 使用相对（无单位）尺寸，因此是可扩展的。可惜的是，由于tikzpicture您提供的已经以使用绝对尺寸的方式定义，因此这肯定会花费大量工作。

为了提供快速的解决方案，您应该加载anyfontsize允许您使用\fontsize任何您想要的字体大小的包，即使那些不是由您使用的字体官方提供的字体。

除此之外，你的代码中还有很多奇怪的事情。

该\fontsize宏采用两个参数，这两个参数已解析为 pt。因此，您在这里只需使用整数即可。
相反\textt{}，您可能想写\texttt[}。
选项arrowhead是该软件包的弃用选项arrows.meta。您应该使用-{>[width=0.3in]}而不是->, arrowhead=0.3in。
该宏\midarrow未定义，因为您在代码中将其注释掉了。

我修正了上述内容，删除了本示例不需要的所有包，并添加了 Ti钾Z 库shapes，但其他方面代码保持不变：

\documentclass[11pt,a4paper,oneside]{article}
