判定 ​

isLineCollection() ​

typescript
const isLineCollection: (tar: any) => tar is LineCollection

属性 ​

redonlay id: string 唯一标识 ​

size: number 子元素数量 ​

show: boolean 是否显示 ​

label: HtmlLabel ​

方法 ​

add 添加线 ​

typescript
add(options: LineCollectionOptions['addOptions']): Polyline

type LineCollectionOptions = {
  addOptions: {
    /** 唯一标识 */
    id?: string;
    /** 显示消失 */
    show?: boolean;
    /** 线宽 */
    width?: number;
    /** 坐标串 */
    positions: Array<Point3d> | Array<[number, number, number?]>;
    /** material为空时有效 线的类型，实线，虚线，带箭头, 发光, 描边的线 */
    type?: 'dotted' | 'line' | 'arrow' | 'glow' | 'outline';
    /** 颜色 */
    color?: MapColor;
    /** 近距离 */
    near?: number;
    /** 远距离 */
    far?: number;
    labelOffset?: [number, number];
    property?: Record<string | symbol, any>;
    /** 虚线配置 */
    dotted?: {
      /** 线段长度 */
      dashLength?: number;
      /** 线段间隔 */
      dashPattern?: number;
    };
    /** 描边配置 */
    outline?: {
      /** 描边宽度 */
      outlineWidth?: number;
      /** 描边颜色 */
      outlineColor?: MapColor;
    };
  };
};
