如何`lockscaleX`和`lockscaleY`，但允許`uniscaling`在Fabric.js中的對象？

Question

如何lockscaleX和lockscaleY但允許uniscaling Fabric.js中的對象？這裏是我的嘗試：

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

這很簡單：

object.lockUniScaling = true;
