问题:

I've edited an SVG with inkscape :

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg id="svg2816" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 48 48" version="1.1" xmlns:cc="http://creativecommons.org/ns#" xmlns:dc="http://purl.org/dc/elements/1.1/">

  <path id="path2836" d="m43,6s6,14,0,29" transform="translate(0,2)" stroke-width="1px" fill="none"/>
 </g>
</svg>

It should look like this:

When I import it with fabricjs :

// volumeOnPrint is the string pasted before
fabric.loadSVGFromString(volumeOnPrint, function(objects, options) {
    var widget = new fabric.PathGroup(objects, options);
    // root is my fabricjs canvas
    root.add(widget);
});

It get that :

(The background is not the issue, it's the one of my canvas)

回答1:

Turns out this was a bug in Fabric.

I just fixed it and pushed new version (0.9.21).

Generally, SVG files created with Inkscape are harder to parse than those created with Illustrator. But we're getting better and better :)

There's a growing visual test suite, to which I added your shape to avoid regressions in the future (let me know if that's OK). Careful as it might take a while to load/parse all the shapes.
