macos - 使用 librsvg/rsvg 使用 ImageMagick 转换 SVG 图像

Question

我知道这个问题在这里有几个答案版本(例如: ImageMagick convert SVG to PNG not working with RSVG enabled )，但实际上我找不到真正解决我的确切问题的方法。我的问题是:我有一个特定的 SVG 文件(我会生成更多)，SVG>PNG 转换器进程中的 ImageMagick 无法完美转换。所以我需要把它改成 librsvg ，因为它确实如此，我用不同的结果测试了这两行:

    convert test.svg test.png  // ( img: http://tinyurl.com/px2lw3v )
    rsvg-convert test.svg -o test.png // ( img: http://tinyurl.com/lreu6sk )

我安装了 HomeBrew。如此处所述: ImageMagick convert SVG to PNG not working with RSVG enabled我使用此代码安装 ImageMagick brew install imagemagick --use-rsvg .我意识到它没有安装 librsvg 所以我需要卸载它并像这样重新安装: brew reinstall imagemagick --with-libsrvg librsvg --use-rsvg :这将 imagemagick 和 librsvg 一起安装到我的 Mac 上。但是没有连接它们: convert -list format | grep SVG结果如下:

 MSVG  SVG       rw+   ImageMagick's own SVG internal renderer
  SVG  SVG       rw+   Scalable Vector Graphics (XML 2.9.0)
 SVGZ  SVG       rw+   Compressed Scalable Vector Graphics (XML 2.9.0)

而这个: convert -list delegate | grep svg结果如下:

    svg =>          "rsvg-convert" -o "%o" "%i"

我安装&卸载&重新安装它们几次&方式但没有改变和脚本 convert test.svg test.png在没有 librsvg 的情况下这样做。我在/usr/local/Cellar/imagemagick/6.8.9-1/lib/ImageMagick/config-Q16/configure.xml 中添加了带有标签的行，但没有任何进展。我不知道该怎么做以及如何连接 ImageMagick 并强制为 convert test.svg test.png 使用不同的库.

谢谢你的帮助。
