android - 桌面和移动设备之间的 SVG 渲染不一致 - Arial 是 SVG 中的网络安全字体吗？

Question

我有一个主要是文本的 SVG。

它在 Windows 7 上的 Firefox 53 和 Chrome 58 中呈现相同(且正确)。

它在 Android 6 上的 Firefox Mobile 53 和 Chrome Mobile 58 中呈现相同(但不正确)。

不正确的呈现与间距有关 - 两个非文本元素的位置不正确，一个非文本元素比应有的宽度更宽。

我的猜测是字体呈现不同 - 但 Android 6 上的 Arial 与 Windows 7 上的 Arial 呈现不同吗？

这是我的 SVG:

<svg xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink"
     viewbox="0 0 805 120">

我需要在我的 XML 中显式声明什么，以便 SVG 在桌面和移动设备之间以相同方式呈现？谢谢。

Answer 1

更好地将文本转换为路径解释(这不仅适用于 SVG，而且适用于任何设计元素；来自 Corel/A.Illustrator 的基本建议)。

其他方法是导入所需的字体(通过使用 Google 字体或 woff/woff2/eot/ttf/svg 组中的内部文件)。请注意，当前解决方案仅适用于 <object>或 inline-svg(不适用于 <img> ):

<defs>
    <style type="text/css">
        @font-face {
            font-family: Arial;
            src: url('font_path/arial-like-font.woff');
        }
    </style>
