Use librsvg / rsvg to convert SVG images with ImageMagick

[zoliqua]

Hello,

I have a probelem, and I don't know what to do. I asked a question on StackOverflow 2 weeks ago, but nobody has answered yet. Can anybody help me?

All the details are here also: http://stackoverflow.com/questions/2451 ... magemagick

I know this question has several answered version here (like this: http://stackoverflow.com/questions/1159 ... vg-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: http://stackoverflow.com/questions/1159 ... vg-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.

I don't know much about Homebrew. I use MacPorts to install my delegates, then I install IM manually from source. This works well. Nevertheless, my suggestions would be start over.

First install librsvg with Homebrew. Then install IM as

brew install imagemagick --with-rsvg

I am not sure if brew uses --use-rsvg or --with-rsvg. But IM typically uses --with-rsvg.

Also you have misspelled librsvg as

brew reinstall imagemagick --with-libsrvg librsvg --use-rsvg

To check if IM recognizes librsvg first see if it is listed with

convert -version

Also a better way is to use

convert -format

and see whether it lists RSVG and its version on the line for SVG.
