渐变填充预设渐变(添加渐变填充)

this.bgShape = new egret.Shape();        this.bgShape.width = w;        this.bgShape.height = h;        let $max: egret.Matrix = this.bgShape.matrix;        $max.a = $max.d = 0;        $max.c = $max.b = 1;        this.bgShape.graphics.beginGradientFill(egret.GradientType.LINEAR, [0xFF0000, 0xD7F0FC], [1.0, 1.0], [0, this.bgShape.height / 3], $max);        this.bgShape.graphics.drawRoundRect(0, 0, this.bgShape.width, this.bgShape.height, 40, 40);        this.bgShape.graphics.endFill();

结果:
