使用librsvg / rsvg通过ImageMagick转换SVG图像 [英] Use librsvg / rsvg to convert SVG images with ImageMagick

问题描述

我知道这个问题在这里有几个答案版本（像这样： ImageMagick将SVG转换为PNG无法启用RSVG ），但实际上我找不到真正的解决方案来解决我的确切问题。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。所以我需要将其更改为 librsvg ，因为它确实如此，我测试了这两行不同的结果：

I know this question has several answered version here (like this: ImageMagick convert SVG to PNG not working with RSVG enabled ), but actually I can't find a real solution to my exact problem. My problem is: I have a specific SVG file (and I will generate more) that ImageMagick inside SVG>PNG convertor process doesn't convert perfectly. So I need to change it to librsvg, because it does, I tested these 2 lines with different result:

    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无法使用已启用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重新安装imagemagick --with-libsrvg librsvg --use-rsvg ：这个已安装的imagemagick& librsvg一起到我的mac。但是没有连接它们： convert -list format | grep SVG 结果为：

I installed HomeBrew. As described here: ImageMagick convert SVG to PNG not working with RSVG enabled I used this code to install ImageMagick brew install imagemagick --use-rsvg. I realized that it not installs librsvg so I needed to uninstall it and reinstall like this: brew reinstall imagemagick --with-libsrvg librsvg --use-rsvg : this installed imagemagick & librsvg together to my mac. BUT doesn't connected them: convert -list format | grep SVG resulted as:

 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 结果为：

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

我安装了&卸载&重新安装了几次&方式，但没有改变，脚本转换test.svg test.png 没有librsvg这样做。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来进行 convert test.svg test.png 。

I installed & uninstalled & reinstalled them several times & ways but nothing changed and the script convert test.svg test.png do it's way without librsvg. I added lines to /usr/local/Cellar/imagemagick/6.8.9-1/lib/ImageMagick/config-Q16/configure.xml with tags but nothing progressed. I don't know what to do and how to connect ImageMagick and force to use different library for convert test.svg test.png.

感谢您的帮助。

(Just adding more context to Zoltan's answer)

使用 brew info imagemagick 查看安装时的可用选项。

Use brew info imagemagick to see available options when installing it.

--with-librsvg
    Build with librsvg support
