我有这个程序，我写的是为我公司的仓库创建bin标签。每个季节，我们都会打印几百个标签。
我遇到的问题是，在模板中使用的字体大小，有时线条包裹，然后事情更难阅读或不适合标签等等。所以我最终通过生成合并文档，并手动减少行换行的各行的字体大小。这是一个真正的痛苦。
我真正想要做的是，对于给定字段的内容，将字体大小设置为等于或小于模板中使用的字体大小的最大大小，以防止换行。但我无法弄清楚如何实现这一目标。
这可能是一个不常见的问题？当然，我有一些明显的解决方案，我不知道？
如果没有别的，我想我可能会使用一个将行长度映射到字体大小的字典，我只是通过反复试验来提出。但似乎必须有一些更好的方法不会向我跳出来，那些对Word互操作有更多经验的人可能会指出我。
这是我的代码：
