i have a problem with the imagemagick convert command. The command works perfect with normal .svg with a standard structure.

But if you use the <defs> area and a <use xlink:href..> reference it doesn't work.

magick convert test.svg -resize 50% test.png

  • works on SVG1

  • doesn't work on SVG2 with xlink:href

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> <svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 29000 17000">
    <circle cx="5000" cy="5000" r="3000" stroke="black" stroke-width="300" fill="green"/>
    </svg>

    </symbol>
    </defs>
    <svg>
    <use xlink:href="#CB0F5BA4"/>
    </svg>
    </svg>

Does anybody can help and give me an idea, what's wrong?

Your second file is huge when rasterized with the default density. But it works fine for me on Imagemagick 7.0.8.25 Q16 Mac OSX using Inkscape when I use a small density to render it. You are using the Imagemagick XML/MSVG internal renderer, which is the least functional. If you install Inkscape on your system, Imagemagick will use that automatically. Otherwise, install RSVG delegate with Imagemagick and try that. Also use magick with IM 7 and not magick convert.
