PolylineOutlineMaterialProperty

用于在线条周围创建一个轮廓效果的材质属性。

语法

new Cesium.PolylineOutlineMaterialProperty(options)
  • options:类型为 {},可选的,表示材质属性的选项。可包含以下属性:
    • color:类型为 Color,可选的,表示轮廓的颜色,默认值为 Color.WHITE
    • outlineColor:类型为 Color,可选的,表示轮廓线的颜色,默认值为 Color.BLACK
    • outlineWidth:类型为 Number,可选的,表示轮廓线的宽度,默认值为 1.0

示例

// 创建一个带有红色轮廓的材质
var material = new Cesium.PolylineOutlineMaterialProperty({
    color: Cesium.Color.BLUE,
    outlineColor: Cesium.Color.RED,
    outlineWidth: 3.0
});

描述

PolylineOutlineMaterialProperty类用于在 Polyline 对象周围创建一个轮廓效果。该材质属性可以与 PolylineGlowMaterialPropertyPolylineDashMaterialProperty 等其它材质属性一起使用,以增强 Polyline 的可视效果。

轮廓线的样式按照以下规则进行绘制:

  1. 绘制一条宽度为 outlineWidth 的轮廓线。
  2. 在轮廓线的两侧各绘制一条宽度为轮廓线宽度的一半的轮廓线,并且颜色为 outlineColor
