   {
       // 基础属性
       shape  : 'icon',       // 必须，shape类标识，需要显式指定
       id     : {string},       // 必须，图形唯一标识，可通过'zrender/tool/guid'方法生成
       zlevel : {number},       // 默认为0，z层level，决定绘画在哪层canvas中
       invisible : {boolean},   // 默认为false，是否可见

// 样式属性，默认状态样式样式属性
       style  : {
           x             : {number},  // 必须，左上角横坐标
           y             : {number},  // 必须，左上角纵坐标
           width         : {number},  // 必须，宽度
           height        : {number},  // 必须，高度
           iconType      : {string},  // 必须，icon类型
       },

// 样式属性，高亮样式属性，当不存在highlightStyle时使用基于默认样式扩展显示
       highlightStyle : {
           // 同style
       }

// 交互属性，详见shape.Base

// 事件属性，详见shape.Base
