我使用了一种在 Blogger 帖子中嵌入 SVG 图像的技术
这可能适用于此。基本上，这是一个两步过程：
- 您可以序列化要嵌入的 SVG，并对它进行 URL 编码。
- 然后，您可以使用 URL 编码的字符串作为 SVG use 元素的 xlink:href 属性中的数据 URI。
这是我用 Batik 测试过的一个工作示例。假设您要嵌入以下 SVG 文档，circle.svg：
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="4in" height="4in" id="the_svg"
viewBox="0 0 4 4" version="1.1"
xmlns="http://www.w3.org/2000/svg">
<circle cx="1" cy="1" r="1" fill="blue" stroke="none" id="the_circle"/>
</svg>
您可以通过将其路径传递给以下小 Rhino 脚本来对其进行 URL 编码：
#!/usr/bin/env rhino
print(escape(readFile(arguments[0])))
当然，如果您想在 Java 中以编程方式执行此操作，那么您将需要一种特定于 Java 的方法来序列化 SVG 文档并对字符串进行 URL 编码。
这将为您提供 URL 编码字符串形式的文档：
%3C%3Fxml%20version%3D%221.0%22%20standalone%3D%22no%22%3F%3E%0A%3C%21DOCTYPE%20svg%20PUBLIC%20%22-//W3C//DTD%20SVG%201.1//EN%22%20%0A%20%20%22http%3A//www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd%22%3E%0A%3Csvg%20width%3D%224in%22%20height%3D%224in%22%20id%3D%22the_svg%22%0A%20%20%20%20%20viewBox%3D%220%200%204%204%22%20version%3D%221.1%22%0A%20%20%20%20%20xmlns%3D%22http%3A//www.w3.org/2000/svg%22%3E%0A%09%3Ccircle%20cx%3D%221%22%20cy%3D%221%22%20r%3D%221%22%20fill%3D%22blue%22%20stroke%3D%22none%22%20id%3D%22the_circle%22/%3E%0A%3C/svg%3E%0A%0A
然后，您可以通过在数据 URI 中使用该文档来嵌入该文档，如下所示：
data:image/svg+xml,%3C%3Fxml%20version%3D%221.0%22%20standalone%3D%22no%22%3F%3E%0A%3C%21DOCTYPE%20svg%20PUBLIC%20%22-//W3C//DTD%20SVG%201.1//EN%22%20%0A%20%20%22http%3A//www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd%22%3E%0A%3Csvg%20width%3D%224in%22%20height%3D%224in%22%20id%3D%22the_svg%22%0A%20%20%20%20%20viewBox%3D%220%200%204%204%22%20version%3D%221.1%22%0A%20%20%20%20%20xmlns%3D%22http%3A//www.w3.org/2000/svg%22%3E%0A%09%3Ccircle%20cx%3D%221%22%20cy%3D%221%22%20r%3D%221%22%20fill%3D%22blue%22%20stroke%3D%22none%22%20id%3D%22the_circle%22/%3E%0A%3C/svg%3E%0A%0A
例如，以下 HTML 文档使用对象标签和数据 URI 来嵌入 SVG 文档：
<html>
<head>
</head>
<body>
<object data="data:image/svg+xml,%3C%3Fxml%20version%3D%221.0%22%20standalone%3D%22no%22%3F%3E%0A%3C%21DOCTYPE%20svg%20PUBLIC%20%22-//W3C//DTD%20SVG%201.1//EN%22%20%0A%20%20%22http%3A//www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd%22%3E%0A%3Csvg%20width%3D%224in%22%20height%3D%224in%22%20id%3D%22the_svg%22%0A%20%20%20%20%20viewBox%3D%220%200%204%204%22%20version%3D%221.1%22%0A%20%20%20%20%20xmlns%3D%22http%3A//www.w3.org/2000/svg%22%3E%0A%09%3Ccircle%20cx%3D%221%22%20cy%3D%221%22%20r%3D%221%22%20fill%3D%22blue%22%20stroke%3D%22none%22%20id%3D%22the_circle%22/%3E%0A%3C/svg%3E%0A%0A" width="400" height="400"></object>
</body>
</html>
您可以使用 SVG 'use' 元素的 xlink:href 属性执行相同的操作，但有一个警告：引用完整文档是非法的。相反，您需要通过 id 引用文档中的元素，并且该元素将被深度克隆到 SVG 宿主文档中。在此示例中，SVG 文档根元素由其 id“the_svg”引用（注意 URI 末尾的哈希标记）。
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="4in" height="4in" id="the_svg"
viewBox="0 0 4 4" version="1.1"
xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<use x="0" y="0" width="4" height="4" xlink:href="data:image/svg+xml,%3C%3Fxml%20version%3D%221.0%22%20standalone%3D%22no%22%3F%3E%0A%3C%21DOCTYPE%20svg%20PUBLIC%20%22-//W3C//DTD%20SVG%201.1//EN%22%20%0A%20%20%22http%3A//www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd%22%3E%0A%3Csvg%20width%3D%224in%22%20height%3D%224in%22%20id%3D%22the_svg%22%0A%20%20%20%20%20viewBox%3D%220%200%204%204%22%20version%3D%221.1%22%0A%20%20%20%20%20xmlns%3D%22http%3A//www.w3.org/2000/svg%22%3E%0A%09%3Ccircle%20cx%3D%221%22%20cy%3D%221%22%20r%3D%221%22%20fill%3D%22blue%22%20stroke%3D%22none%22%20id%3D%22the_circle%22/%3E%0A%3C/svg%3E%0A%0A#the_svg"/>
</svg>
仅供参考，这在 Batik 1.7 中运行良好（在 Squiggle 浏览器中测试），但在 Chromium 或 Firefox 中不起作用。
