arcgis js 4 使用d3.js 添加滤镜光求职学习资料

本文介绍了arcgis js 4 使用d3.js 添加滤镜光求职学习资料,有助于帮助完成毕业设计以及求职,是一篇很好的资料。

对技术面试,学习经验等有一些体会,在此分享。

我们利用d3滤镜为d3元素增加光的效果

我们存一些全局变量

        this.animateOption = null;         this.defs = null;         this.animateId = "";         this.feDropShadow = null;

滤镜初始化

function create(option){         this.animateOption =  option;         this.defs = this.svg.append("defs");         let linearGradient = this.defs.append("filter")             .attr("id",this.animateOption.id)             .attr("x","-50%")             .attr("y","-50%")             .attr("width","200%")             .attr("height","200%")          this.feDropShadow = linearGradient.append("feDropShadow")             .attr("dx", "0")             .attr("dy","0")             .attr("stdDeviation","0")             .attr("flood-color",this.animateOption.floodColor) }

启动滤镜
“`javascript
function start(){
let multiplier = this.animateOption.speed;
let xDiff= 0.01;
let yDiff= 0.01;
let that = this;
function setBlur(x,y){
that.feDropShadow.attr(“stdDeviation”,x);
}
let flag = true;

    (function updateMotionBlur(){
