使用 TikZ spy 在放大的图片上添加箭头和文字

我想在放大图片上添加一些箭头和文字。在放大图片上添加 A、B 和 C。有人能帮我解决这个问题吗？谢谢在此处输入图片描述

答案1

这是其中一种方法。为了确保箭头停留在监视区域的顶部，我使用了库backgrounds。将箭头设为B绿色以证明它确实位于顶部。

答案2

以下是基于的答案这个较旧的答案概念上非常类似于Milo 的回答很棒。这个答案的优点在于，它带有缩放部分的局部坐标系，这可能使注释的放置更加直接。特别是，如果您决定移动放大的内容和/或更改缩放系数，注释将会调整。Milos 方法也适用于移动放大的内容。为了获得更好的可见性，我还使用了轮廓箭头。
