Question

我使用以下代码通过FabricJS将SVG文件添加到画布：

    fabric.loadSVGFromURL(stampURL, function (objects, options) {
    var obj = fabric.util.groupSVGElements(objects, options);
    obj.set({
        fill: stampColor,
        left: stampX,
        top: stampY,
        scaleY: stampScale,
        scaleX: stampScale,
        originX: 'center',
        originY: 'center',
        hasControls: false,
        hasBorders: true,
        selectable: false,
        perPixelTargetFind: true
    });
    Fcanvas.add(obj).renderAll();
});

对于某些文件它完美无缺。这些好文件最初是XAML文件，我用Inkscape将它们转换为SVG。

今天我从我的平面设计师处获得了新的SVG文件，我开始在consol中收到这些错误：

fabric1_5dev.js:4264 TypeError: (this.getObjects(...)[0].get(...) || "").toLowerCase is not a function
    at klass.fabric.PathGroup.fabric.util.createClass.isSameColor (..../js/fabric1_5dev.js:17008:68)

使用Adobe Illustrator生成文件：＆＃34;生成器：Adobe Illustrator 14.0.0，SVG导出插件。 SVG版本：6.00 Build 43363＆＃34;

我必须提到这些文件在浏览器或Inkscape中完美打开。

我甚至尝试将这些文件加载到Inkscape中并将它们保存为普通SVG，但这对它们都没有帮助。

这是一个不起作用的SVG文件：

任何想法这个文件有什么问题？

更新我怀疑渐变填充颜色并尝试以相同的方式创建另一个文件，但没有渐变填充颜色，它的工作原理。所以看起来这就是问题所在。

有谁知道FabricJS是否不支持包含线性渐变着色的文件？

更新相同的SVG在kitchennsink中工作，所以问题可能在于我的加载代码。任何想法？

Answer 1

确定!!找到了。

FabricJS失败，因为我试图设置此SVG的感觉颜色。问题在于函数：isSameColor

这是Andrea Bogazzi在GitHub

中提供的解决方法

FabricJS支持哪些类型的SVG文件？
