这是前两个问题的组合（及其各自的答案）：如何为页面顶部旁边带有 svg 的部分创建命令？和如何使用tikzpicture环境与矩形形状进行对话？
问题
请考虑这个 MWE（它很长因为我需要显示实际的页眉和页脚）：

此组合源代码来自@薛定谔的猫一旦所提问题的答案被接受，他们就会做出修改。
查看输出：
缺少标题。有时它会与形状发生冲突。
此外，如果我们增加一个图像尺寸，比如说我们改为\You[start,image={scale=1}]{example-image-duck}，\You[start,image={scale=1.35}]{example-image-duck}就会与页脚发生冲突：
问题
有没有办法防止与页眉和页脚发生冲突，同时保持大小？我不在乎一个不适合页面的形状是否必须转到下一页。我不想发生冲突。
答案1
此代码翻译了 Ti钾基于 Z 的形状变成tcolorboxes。这样做的好处是它们可破坏。因此您浪费的空间更少。如果您使用键graphics，框将根据内容调整其大小。
