svg中的外部引用图像在转换为base64并嵌入img标记时不显示

我有一个svg图像。 首先，我将该图像转换为base64字符串。 然后我在img标记中显示base64 svg字符串

问题是当我被引用svg文件时，svg中的图像正在显示。 但在将其转换为base64时，它不会显示

问题只在mozilla中出现

当您使用SVG作为图像格式时，即在HTML

标记中（如您所做）或作为SVG文件的背景图像

SVG图像引用外部jpg文件，这是不允许的。不过，你可以做到这一点

获取jpg图像数据，在base64中对其进行编码，并将其嵌入到SVG文件中

将整个新SVG文件以及编码的内部图像数据编码为base64，然后将其作为您的

如果您使用javascript，您可以遵循以下解决方案：

而不是使用img标记，如果我们使用object标记，那么图像将在所有浏览器中正确显示

谢谢你的回答，罗伯特。嵌入base64图像字符串在所有浏览器中都可以正常工作。但它会增加svg的大小，这是我不想要的。我只需要设置图像的url。这个问题提供了一些关于如何嵌入svg以将png图像（BLOB）转换为base64的重要信息，请看，将数据添加到html或svg非常简单。
