flash 创建复杂渐变填充效果

作者：袖梨 2022-06-28

创建一个新的 Flash 文档，并将其保存为 radialgradient.fla。
将下面的 ActionScript 添加到时间轴的第 1 帧：

代码如下

复制代码

this.createEmptyMovieClip("gradient_mc", 10);
var fillType:String = "radial";
var colors:Array = [0xFF0000, 0x0000FF];
var alphas:Array = [100, 100];
var ratios:Array = [0, 0xFF];
var matrix:Object = {a:200, b:0, c:0, d:0, e:200, f:0, g:200, h:200, i:1};
var spreadMethod:String = "reflect";
var interpolationMethod:String = "linearRGB";
var focalPointRatio:Number = 0.9;
with (gradient_mc) {
    beginGradientFill(fillType, colors, alphas, ratios, matrix, spreadMethod, interpolationMethod, focalPointRatio);
    moveTo(100, 100);
    lineTo(100, 300);
    lineTo(300, 300);
    lineTo(300, 100);
    lineTo(100, 100);
    endFill();
}
