Question

我的画布是1000 x 1000，我希望导入的svg是500 x 500但它的svg尺寸是300 x 300（插图画家的画板尺寸）

我如何在这个加载的svg上object.setHeight(400)？当我做类似的事情时，选择框最终填充或与对象不对齐。

addShapeObject = function(canvas, element, scope) {
    loadingElementIds.push(element.id);
    fabric.loadSVGFromURL('/lib/svg/' + element.filename + '.svg', function(objects, options) {
        var object = fabric.util.groupSVGElements(objects, options);
        object.top = element.top;
        object.left = element.left;


        object.rotatingPointOffset = 20;
        object.scaleY = element.height / object.height;
        object.scaleX = element.width / object.width;

        object.padding = 5;

        canvas.add(object).renderAll();
        sortObjects(canvas);
        setObjectsZoom(canvas, scope);
    });
},

示例SVG：

Answer 1

您无法更改导入的SVG（pathGroup）的宽度和高度。 Widht和Height由构成SVG本身的未缩放部分定义。您可以做的是加载SVG然后正确缩放它。

scaleToWidth(x)
scaleToHeight(x)

FabricJS - 设置导入的svg的高度和宽度
