[]this.bitmap.activeResource is not a function TypeError: this.bitmap.activeResource is not a function

if (bitmap&&bitmap._addReference){
bitmap._addReference();
}

这个代码过滤已经加了，但是会报下面这个错
this.bitmap.activeResource is not a function
TypeError: this.bitmap.activeResource is not a function
 
 
使用代码如下:var rankTexture:Texture = new Texture(Laya.Browser.window.sharedCanvas);
var image:Laya.Image = new Laya.Image();
image.source = rankTexture;
Laya.stage.addChild(image);
