套用灰階濾鏡

let s1 = new egret.Shape();
s1.graphics.beginFill(0xFF0000);
s1.graphics.drawRect(0,0,100,100);
s1.graphics.endFill();
this.addChild(s1);
let m:number[] = [
    0.3, 0.59, 0.11, 0, 0,
    0.3, 0.59, 0.11, 0, 0,
    0.3, 0.59, 0.11, 0, 0,
    0  , 0   , 0   , 1, 0
];
s1.filters = [new egret.ColorMatrixFilter(m)];
