一个画图的例子

ngAfterViewInit() {
    this.renderChar();

    var stage = new createjs.Stage("analysisPath");
    var circle1 = new createjs.Shape();
    circle1.graphics.beginFill("#000").drawRect(0, 0, 200, 100);
    circle1.x = 0;
    circle1.y = 0;
    stage.addChild(circle1);

    var circle2 = new createjs.Shape();
    circle2.graphics.beginFill("000").drawRect(0, 300, 200, 100);
    circle2.x = 0;
    circle2.y = 300;
    stage.addChild(circle2);

    var current = new createjs.Shape().set({x:100, y:circle1.y});
    stage.addChild(current);
    var w = circle2.x - circle1.x;
    var h = circle2.y - circle1.y;
    var l = Math.sqrt(w*w+h*h);
    this.drawArrow(current, l);
    current.rotation = Math.atan2(h,w) * 180/Math.PI;
    stage.update();
}

drawArrow(arrow:any, length:number) {
    arrow.graphics.clear().ss(3).s("#000").mt(0, 0);
    var arrowSize = 15;
    arrow.graphics.qt(0, 0, length, 0);
    // Draw the arrow head at the end.
    arrow.graphics.f("#000");
    arrow.graphics.dp(length - arrowSize, 0, arrowSize, 3);
