# MapboxImageLayer

> 静态图片覆盖图层，把一张图片按四角经纬度贴合到地图上。

## 简介

`MapboxImageLayer` 把一张图片按四角经纬度（左上 / 右上 / 右下 / 左下）贴合到地图，常用于雷达图、扫描影像、历史地图等叠加。内部以 `image` 源 + `raster` 图层实现。

## 用法

把一张雷达图叠加到指定区域：

```vue [ImageLayerExample.vue]
<script setup lang="ts">
// 四角经纬度：左上 / 右上 / 右下 / 左下
const coordinates: [[number, number], [number, number], [number, number], [number, number]] = [
  [-80.425, 46.437],
  [-71.516, 46.437],
  [-71.516, 37.936],
  [-80.425, 37.936]
]
</script>

<template>
  <div class="h-115 w-full overflow-hidden rounded-(--ui-radius) border border-default">
    <MapboxMap :options="{ style: 'mapbox://styles/mapbox/light-v11', center: [-75.79, 42.1], zoom: 4 }">
      <MapboxImageLayer
        url="https://docs.mapbox.com/mapbox-gl-js/assets/radar.gif"
        :coordinates="coordinates"
        :opacity="0.85"
      />
    </MapboxMap>
  </div>
</template>
```

## API

### Props

```ts
/**
 * Props for the MapboxImageLayer component
 */
interface MapboxImageLayerProps {
  /**
   * 图片地址
   */
  url: string;
  /**
   * 四角经纬度：左上/右上/右下/左下
   */
  coordinates: [[number, number], [number, number], [number, number], [number, number]];
  /**
   * 图层 id；省略时自动生成
   */
  layerId?: string | undefined;
  /**
   * 不透明度
   * @default "1"
   */
  opacity?: number | undefined;
  /**
   * 插入到该图层之前
   */
  beforeId?: string | undefined;
}
```
