如何`lockscaleX`和`lockscaleY`但允许`unisaling`在Fabric.js中的对象？

Question

如何lockscaleX和lockscaleY但允许uniscaling Fabric.js中的对象？这是我试过的：

if (shape.scaleX != 1 && shape.scaleY != 1) {
                    shape.width = shape.scaleX * shape.width;
                    shape.height = shape.scaleY * shape.height;
                    shape.scaleX = 1;
                    shape.scaleY = 1;
                } else {
                    shape.scaleX = 1;
                    shape.scaleY = 1;
                }

Answer 1

这很简单：

object.lockUniScaling = true;
