# 如何將線條新增至靜態地圖
<a name="how-to-add-line-static"></a>

 在本主題中，您將了解如何使用 Amazon Location Service 將線條新增至靜態地圖。我們將介紹支援的樣式選項、如何使用 GeoJSON 定義線條，以及如何套用自訂樣式，例如顏色、寬度和大綱。我們也將探索如何針對線條寬度等屬性使用不同的測量單位。

## 支援的樣式
<a name="supported-styling"></a>


| 名稱 | Type | 預設 | 描述 | 
| --- | --- | --- | --- | 
| `color` | 顏色 | 風格相依 | 線條顏色。 | 
| `width` | 整數/字串 | 2 | 線條寬度。如需詳細資訊，請參閱[如何將線條新增至靜態地圖](#how-to-add-line-static)。 | 
| `outline-color`  | 顏色 | 風格相依 | 線條輪廓顏色。 | 
|  `outline-width`  | 整數/字串 | 0 （關閉） | 外框的寬度。如需詳細資訊，請參閱[如何將線條新增至靜態地圖](#how-to-add-line-static)。 | 

## 支援的單位
<a name="supported-unit"></a>


| 單位 | 描述 | 
| --- | --- | 
| 整數，例如， `5` | Pixels | 
| 沒有單位的字串，例如 `"5"` | Pixels | 
| `"px"` | Pixels | 
| `"m"` | 計量器 | 
|  `"km"`  | 公里 | 
| `"mi"` | 英里 | 
| `"ft"` | 足部 | 
| `"yd"` | Yards | 
| `"%"` | 特定屬性的預設值百分比，以像素為單位。例如，如果 的預設值`width`為`2`像素，則 `200%` 為`4`像素。 `%` 是敏感字元，必須在請求 URL 中編碼為 `%25`。 | 

## 新增行
<a name="add-a-line"></a>

 在此範例中，您將從 Vancouver 中的位置新增一條線到史坦利公園。系統會使用 GeoJSON 格式搭配定義的座標來建立該行。
