如何创建一个具有纯色背景和顶部波浪形接缝的文本框？

我正在尝试用 LaTeX 创建动画 GIF 信息图。为此，我想将文本框排列成三列布局，行框采用各种颜色，并用波浪线（理想情况下是正弦波）隔开。我有一个关于如何使用 绘制一条分隔线的想法tikz，但是每个框的背景顶部都必须有匹配的接缝，而且似乎需要\foreach在\fill命令中使用 ，而这在语法上似乎是不可能的。有什么tikz合适的工具吗？我不想用几个相邻的填充形状来绘制它，因为在某些 PDF 查看器中查看时可能会导致闪烁（我也想创建它的 PDF 版本）。大约有 12 个这样的框，颜色和高度各异，所以如果可以自动化的话会很方便。

小样

  \newpage

这大致是上述代码产生的输出。出于某种原因，背景的高度只有应有大小的一半。我也很难为三列容器添加一些填充minipage，但这可能值得单独提出一个问题。

現在結果。

在 TikZ 中完成整个操作：

填充是在background图层中完成的；波浪边框是使用剪辑和snake装饰制作的。
