将 viewBox 坐标转换为 svg 并将一个 svg 嵌入到另一个

有这样一个svg - 这是一个简单的二维码。viewBox 可以是任意的，具体取决于文本的大小和 QRCorrectLevel 的值。

<svg version="1.2" baseProfile="tiny" viewBox="0 0 23 23" fill="#000000"><rect x="0" y="0" width="23" height="23" fill="#ffffff" style="fill: #ffffff !important"></rect><rect x="1" y="1" width="1"

还有另一个带有viewBox="0 0 500 500"的“ svg ”元素。据我所知，您只能使用“图像”将svg插入另一个svg ，但这不是最方便的选择，您必须先将图像记录在服务器上，目标是动态地将二维码插入另一个svg具有不同 viewBox 值的元素。

如果你尝试将第一个svg（用g替换svg）插入第二个，那么坐标自然会有问题。

也许还有其他一些方法可以将一个 svg 嵌入到另一个中，或者轻松地重新计算新 viewBox 的坐标？
