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

Question

如何lockscaleX和lockscaleY但允许uniscaling Fabric.js中的对象？这里是我的尝试：

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;
