使用librsvg/rsvg通过ImageMagick转换SVG图像

Question

我知道这个问题有几个在这里回答版本(这样的:ImageMagick的SVG转换为PNG不是RSVG工作启用),但实际上我无法找到一个真正解决我确切的问题.我的问题是:我有一个特定的SVG文件(我将生成更多),SVG> PNG转换器进程内的ImageMagick无法完美转换.所以我需要将它改为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.如下所述:ImageMagick将SVG转换为PNG无法启用RSVG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重新安装如下brew reinstall imagemagick --with-libsrvg librsvg --use-rsvg::这将imagemagick和librsvg一起安装到我的mac.但没有连接它们: 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)

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

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

我安装和卸载并重新安装了几次和方法,但没有改变,脚本convert test.svg test.png没有librsvg.我在/usr/local/Cellar/imagemagick/6.8.9-1/lib/ImageMagick/config-Q16/configure.xml中添加了带标签的行,但没有任何进展.我不知道该怎么做以及如何连接ImageMagick并强制使用不同的库convert test.svg test.png.

谢谢您的帮助.

Answer 1

我试过,我的解决方案在Mac上:

1. 运行brew doctor和brew update
2. 简单地使用brew reinstall imagemagick --with-librsvg// - 你可能拼错了!
3. 试试吧.它应该工作!

它有用吗？

Answer 2

(只需在Zoltan的答案中添加更多上下文)

用于brew info imagemagick在安装时查看可用选项.

--with-librsvg
    Build with librsvg support

Answer 3

If you want to use Homebrew to install imagemagick with svg support, you need to use an older version. They removed options from the installation process early 2019.

    brew install https://github.com/Homebrew/homebrew-core/raw/46a2ef7c9f0380b8e19f8dfe37270caa27581353/Formula/imagemagick.rb --with-librsvg
