我需要一些帮助 .

我有一个String JSON，它包含FabricJS的图像对象的结构，而不是包含过滤器 .

我想在画布中加载图像时应用这些过滤器 .

我怎么能这样做？

"1":
    {
        "type": "image",
        "originX": "left",
        "originY": "top",
        "lockMovementX": false,
        "lockMovementY": false,
        "lockScalingX": false,
        "lockScalingY": false,
        "lockRotation": false,
        "lockUniScaling": false,
        "lockScalingFlip": false,
        "left": 193.13,
        "top": 70.87,
        "width": 718,
        "height": 647,
        "fill": "rgb(0,0,0)",
        "stroke": null,
        "strokeWidth": 1,
        "strokeDashArray": null,
        "strokeLineCap": "butt",
        "strokeLineJoin": "miter",
        "strokeMiterLimit": 10,
        "scaleX": 0.17,
        "scaleY": 0.17,
        "angle": 0,
        "flipX": false,
        "flipY": false,
        "opacity": 1,
        "shadow": null,
        "visible": true,
        "clipTo": null,
        "backgroundColor": "",
        "fillRule": "nonzero",
        "globalCompositeOperation": "source-over",
        "transformMatrix": null,
        "src": "cuadradito.png",
        "filters": [
            {
                "type": "Invert"
            }
        ],
        "crossOrigin": "",
        "alignX": "none",
        "alignY": "none",
        "meetOrSlice": "meet"
    }

顶部的代码是图像的对象 . 此代码是从BD加载的，带有ajax请求 .
