使用 Imagick 将 SVG 转换为 PNG 时无法获得正确的图像

Question

我有由svg.js 库生成的 SVG HTML 代码。使用 PHP 的 Imagick 我想将 SVG HTML 转换为 PNG。

PHP：

$svg = '<?xml version="1.0" encoding="UTF-8" standalone="no"?><svg id="SvgjsSvg2552" xmlns="http://www.w3.org/2000/svg" version="1.1" width="1500" height="1500"

这就是我得到的。左边的图片（取自浏览器）是一个想要的状态。魔术没有发生:)

我已经尝试过更简单的 SVG HTML 代码，并且成功了。生成的 SVG HTML 代码有什么问题吗？我已经验证了生成的 SVG，没有发现任何错误。

非常感谢。

Answer 1

到目前为止，导出 svg 的最佳方式是使用 Inkscape 可执行文件。过去五年我们一直在生产中使用它，它坚如磐石。在 Mac 上，我们像这样使用 Inkscape 来导出 png：

/Applications/Inkscape.app/Contents/Resources/script filename.svg --export-png=filename.png

我们已经测试了很多 svg 解析器，但没有一个能像 Inkscape 那样出色。与svg export plugin 和svg.js 一起使用，效果非常好。

Answer 2

您遇到的问题是 ImageMagick 的内部 SVG 子流程不完全支持的相关 SVG 1.1 功能。特别是font-stretch="narrower" 属性和g 元素的嵌套路径分组。最好的解决方法是安装 RSVG 委托并通过运行以下命令进行确认...

identify -list format
# or
identify -list delegate

另一种选择是重新评估生成 SVG 的方式。 svg.js 之类的工具既简单又轻便，但生成的输出可能非常复杂，包含不必要的元素和转换。 ImageMagick 还支持SVG path specs。您也许可以直接在 PHP-Imagick 中生成图像。
