问题
I have an SVG that displays fine in Chrome, but when I use it in an HTML page, it doesn't use the right font, instead using the default.
<svg version="1.1" xmlns="http://www.w3.org/2000/svg">
<defs>
<style type="text/css">
<![CDATA[
/* latin-ext */
@font-face {
font-family: 'Roboto-Black';
src: url(./Roboto-Black.ttf)
}
]]>
</style>
</defs>
<text style="font-family: 'Roboto-Black'; font-weight:normal;" transform="matrix(1, 0, 0, 1, 239.2, 51.394)">
<tspan x="-101.469" y="27" font-family="Roboto-Black" font-size="72" fill="#000000">TEST</tspan>
</text>
</svg>
The SVG displays fine in Chrome, but when displayed in an HTML page, it doesn't use the right font.
<html>
<head></head>
<body>
<img src="test.svg" width="100%">
</body>
</html>
What am I missing?
Addendum: Although a valid solution was offered below, I found it was easier to include the svg code directly in the html, instead of referencing an svg file. That way the problem doesn't arise.
回答1:
When used as an image (via an html <img> tag, an SVG <image> tag or as a CSS background-image) SVG must be consist of a single file in order to protect user privacy.
You can use a font, but you'll need to convert the font data to a data URI and embed the font in the SVG file.
