mapgis-3d-analysis-slope

# 属性

# vueKey

  • 类型: String
  • 可选
  • 非侦听属性
  • 默认值: default
  • 描述: mapgis-web-scene 组件的 ID,当使用多个 mapgis-web-scene 组件时,需要指定该值,来唯一标识 mapgis-web-scene 组件,同时 mapgis-web-scene 插槽中的组件也需要传入相同的 vueKey,让组件知道应该作用于哪一个 mapgis-web-scene。

# vueIndex

  • 类型: Number
  • 可选
  • 非侦听属性
  • 默认值: (Math.random() * 100000000).toFixed(0)随机计算值
  • 描述: 当 mapgis-web-scene 插槽中使用了多个相同组件时,例如多个 mapgis-3d-igs-doc-layer 组件,用来区分组件的标识符。

# rampColors

  • 类型: Array
  • 可选
  • 侦听属性
  • 描述: 坡度分析角度颜色数组
  • 默认值:
[
  { min: 0, max: 15, color: "rgba(244, 67, 54, 0.5)" },
  { min: 15, max: 30, color: "rgba(233, 30, 99, 0.5)" },
  { min: 30, max: 45, color: "rgba(156, 39, 176, 0.5)" },
  { min: 45, max: 60, color: "rgba(255, 235, 59, 0.5)" },
  { min: 60, max: 75, color: "rgba(96, 125, 139, 0.5)" },
  { min: 75, max: 90, color: "rgba(76, 175, 80, 0.5)" }
]

# 方法

# analysis

  • Description: 坡度分析

# remove

  • Description: 移除坡度分析对象,移除坡度分析结果。

# 事件

# @load

  • Description: 在 Slope 加载完毕后发送该事件
  • Payload 坡度分析对象

# 示例
