理解 viewBox：如何使用正确的尺寸
Understanding viewBox: how to use the correct size
看看这个SVG。如您所见，我将其作为 base64 数据 uri 提供。这样做的原因是我想将它用作背景图像。但是，我在让它按照我想要的方式工作时遇到了一些困难，而且我担心我对 viewbox 属性有一些误解。但是让我先举一个我想要完成的例子。

如果你仔细看，你会发现背景图片没有居中。 （当你打开你的开发工具并突出显示伪元素的框时，它非常清楚。）起初我以为你不能将数据 URI 居中，但后来我注意到当你在 devtools 中将鼠标悬停在数据 URI 上时，它说"image" 的尺寸为 300x30。 Chrome 还显示了图像的小预览。从这里可以清楚地看出尺寸不正确。 10 比 1 的比例不正确。
数据 URI 是从以下 SVG 生成的，我在其中指定了 viewBox 属性的值。尽管它接近 10-1，但事实并非如此。所以我在想出了什么问题，因为嵌入式数据 URI 不遵守建议的维度。

所以我很茫然。为什么 SVG/data URI 背景不遵循在 viewBox 中指定的 ratio/box 作为背景使用？我该如何解决这个问题？
我相信您原来的 SVN 不是您认为的比例，所以 viewbox 中宽高的变化影响了您的整体视图。
