Use librsvg / rsvg to convert SVG images with ImageMagick

问题

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 )

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)

while this: convert -list delegate | grep svg resulted as:

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

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.

Thank you for your help.

(Just adding more context to Zoltan's answer)

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

--with-librsvg
    Build with librsvg support

回答2:

I tried and my solution is on Mac:

run brew doctor and brew update
use simply brew reinstall imagemagick --with-librsvg // - you may misspelled!
try it. it should work!

Is it work?

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
