参数。

Name	Type	Default	Description
`id`	string		可选专题图层 ID。默认使用 CommonUtil.createUniqueID("themeLayer_") 创建专题图层 ID。
`opacity`	number	1	可选图层不透明度。
`alwaysMapCRS`	boolean	false	可选要素坐标是否和地图坐标系一致，要素默认是经纬度坐标。
`attribution`	string	'Map Data <span>© <a href='http://support.supermap.com.cn/product/iServer.aspx' title='SuperMap iServer' target='_blank'>SuperMap iServer</a></span>'	可选版权描述信息。
`TFEvents`	Array		可选专题要素事件临时存储。
`nodesClipPixel`	number	2	可选节点抽稀像素距离。
`isHoverAble`	boolean	false	可选图形是否在 hover 时高亮。
`isMultiHover`	boolean	false	可选是否多图形同时高亮，用于高亮同一个数据对应的所有图形（如：多面）。
`isClickAble`	boolean	true	可选图形是否可点击。

`attribution`	string	'Map Data <span>© <a href='http://support.supermap.com.cn/product/iServer.aspx' title='SuperMap iServer' target='_blank'>SuperMap iServer</a></span>'	可选版权描述信息。
