什么类型的SVG文件fabricJS支持？
我使用下面的代码在FabricJS上添加SVG文件到画布上：
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();
});
对于一些文件它的作品完美。 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那里得到了新的SVG文件，我开始在控制台中看到这些错误：
fabric1_5dev.js:4264 TypeError: (this.getObjects(...)[0].get(...) || "").toLowerCase is not a function

这些文件是用Adobe Illustrator生成的：“Generator：Adobe Illustrator 14.0.0，SVG Export Plug-In。SVG Version：6.00 Build 43363”
我必须提及这些文件在浏览器或Inkscape中完美打开。
我甚至试图将这些文件加载到Inkscape中，并将它们保存为普通的SVG，但这也没有帮助。
这里是一个不起作用的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，并尝试另一个文件创建相同的方式，但没有渐变填充颜色，它的工作原理。 所以看起来这是问题所在。
有谁知道如果FabricJS不支持包含线性渐变着色的文件？
更新：相同的SVG在kitchensink中工作，所以问题可能在于我的加载代码。 有任何想法吗？
好！！ 找到它 。
FabricJS失败了，因为我试图设置这个SVG的感觉颜色。 问题出现在函数isSameColor中
这里是GitHub的Andrea Bogazzi向我提供的一个修复
fabric.PathGroup.prototype.isSameColor = function() {
var firstPathFill = this.getObjects()[0].get('fill') || '';
if (typeof firstPathFill !== 'string') {
return false;
}
firstPathFill = firstPathFill.toLowerCase();
return this.getObjects().every(function(path) {
var pathFill = path.get('fill') || '';
return typeof pathFill === 'string' && (pathFill).toLowerCase() === firstPathFill;
});
};
