根据 tcolorbox 的高度调整 tcolorbox 中 tikzfigure 的大小

根据 tcolorbox 的高度调整 tcolorbox 中 tikzfigure 的大小

在我的书中，我得到了许多不同类型的盒子，所以我制作了一些宏，根据它们的参数自动放置盒子。在此处输入图片描述

这是其中之一。到目前为止，我制作了一些里面有大“+”和“-”的盒子，还有一些里面有小“+”和“-”的盒子。如果我能设法根据盒子的高度调整标志的大小，那就太好了。

由于我有各种类型的组合（+-、++、--、+=、==、..），我编写这些宏时尽量减少源代码（根据我的技能）。如果我可以在宏中获取高度\ds，我可以通过重新计算符号的尺寸、坐标等来调整符号。

有人有线索吗？

更新后的版本：

第一个版本的代码（见下文）有一个问题：如果框高度太大，那么标志将超出其对应的框；这可以通过选择标志长度的最大值来解决。以下代码显示了这样一种可能性；长度（大约）是框高度与其宽度的一半之间的最小值：

  1. 形状的大小和线宽将根据框的高度自动调整。

  2. 请注意，现在\dosign只有两个强制参数（而不是原来的九个参数），并且\doibs只有三个参数。

  3. 的第三个参数\doibs用于决定绘制哪些符号；我为“加号”( p)、“减号”( m) 和“等号”( e) 实现了九种组合。例如，me在第三个参数中使用表示在左侧绘制“减号”，在右侧绘制“等号”；pm在第三个参数中使用表示在左侧绘制“加号”，在右侧绘制“减号”。
