        <p>IGS地图图片图层，<br/>
支持IGS1.0和2.0两个服务版本，支持自定义坐标系，当IGS版本是1.0时，需要手动设置图层坐标系，当IGS版本是2.0时，会自动读取元信息上的坐标系，不需要用户指定<br/>
<br><br>[ES5引入方式]：<br/>
zondy.layer.IGSMapImageLayer() <br/>
[ES6引入方式]：<br/>
import { IGSMapImageLayer } from &quot;@mapgis/webclient-common&quot; <br/>
<br/>
针对图层的操作请在图层加载完毕事件中进行<br/>
Layer.on('layerview-created', function (result) {<br/>
console.log(&quot;加载完毕:&quot;, result.layer)<br/>
});<br/>
如果不想在该事件中放入业务代码，则请确认图层资源已加载完毕后再进行操作<br/>
if(layer.loadStatus === 'loaded') {<br/>
