在fabric.js中修改对象后,如何获取Text对象的字体大小？

以下是我的代码.

var text = new fabric.Text(imgText, {
                left: 10,
                top: 5,
                fontSize: 15,
                fontFamily: 'Verdana',
                fill: 'white'
            });
            text.scaleToWidth(canvas.width * 0.5);
            text.setControlsVisibility(canvasConfig);
            canvas.add(text);
            canvas.renderAll();
var objects = canvas.getActiveObject();

            var obj = objects;
            if (!obj) {
                return;
            }
            //console.log(obj.get('fontSize') *= obj.scaleX); 
            var angle = obj.get('angle');

            var objWidth = obj.get('width') * obj.scaleX;
            var objWidthPercent = objWidth / canvas.width * 100;

            var objHeight = obj.get('height') * obj.scaleY;
            var objHeightPercent = objHeight / canvas.height * 100;

            var bound = obj.getBoundingRect();
            var …

这是我的代码。

<canvas id="c" width="240" height="300" style="border:1px solid #000000"></canvas>

<script>
    var canvas = new fabric.Canvas('c');
     canvas.backgroundColor = 'yellow';


     canvas.renderAll();

     fabric.Image.fromURL(<?php echo '"' . $url . '"'; ?>, function(myImg) {
      var img1 = myImg.set({ left: 0, top: 0 ,width:150,height:150});
      canvas.add(img1); 
     });

     function objectMovedListener(ev) {
      let target = ev.target;
      console.log('left', target.left, 'top', target.top, 'width', target.width * target.scaleX, 'height', target.height * target.scaleY);
     }

    canvas.on('object:modified', objectMovedListener);
</script>

我不明白出了什么问题。对象位置 TOP & LEFT 显示正确，但高度和宽度推错了。

请帮我。
