文本的字体系列。可能值取决于图层类型,以及您使用的是 MapView 还是 SceneView。有关详细说明,请参阅标注指南页面,或单击下面的 Read more

3D SceneViews 的字体系列

3D SceneViews 支持的字体系列取决于安装在用户计算机和 Web 浏览器上的字体。如果应用程序使用了未安装的字体,Font 类将实现一个回退机制,该机制将使用默认字体系列值,即 sans-serif。有关如何在 WindowsMac 上安装新字体的说明,请参阅这些参考资料。

本地未安装的字体也可通过在 css 文件中定义 @font-face 并从符号层中的 family 属性引用它来从 url 加载。

2D MapImageLayer 的字体系列

MapView 中的 MapImageLayers 支持的字体系列取决于安装在发布图层的 GeoScene Server 上的字体。如果应用程序使用了未安装的字体,Font 类将实现一个回退机制,该机制将使用默认字体系列值,即 sans-serif

2D FeatureLayer、CSVLayer、StreamLayer 和 TextSymbol 的字体系列

支持的字体系列基于 .pbf 格式的托管字体文件。默认情况下,可用字体大多与 GeoScene 矢量底图使用的字体相同。这些字体可通过 https://static.geoscene.cn/fonts 获得。通过设置 geosceneConfig.fontsUrl 属性,可以将 URL 配置为指向您自己的字体资源。如果应用程序使用了未安装的字体,Font 类将实现一个回退机制,该机制将使用默认字体系列值,即 sans-serif。这使用 Arial Unicode MS 字体文件。

标注概述页面中提供了下表中列出的字体的预览。

方法详细说明

addHandles(handleOrHandles, groupKey)inherited
起始版本:GeoScene Maps SDK for JavaScript 4.25

添加一个或多个与对象的生命周期相关联的句柄。当对象被销毁时,将移除句柄。

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

// Handle gets removed when the object is destroyed.
this.addHandles(handle);
参数
handleOrHandles WatchHandle|WatchHandle[]

对象销毁后,标记为要移除的句柄。

groupKey *
optional

标识句柄应添加到的组的键。组中的所有句柄稍后都可使用 Accessor.removeHandles() 进行删除。如果未提供键,则句柄将被添加到默认组。

clone(){Font}

创建 font 对象的深度克隆。

返回
类型 描述
Font 调用此方法的对象的深度克隆。
fromJSON(json){*}static

创建此类的新实例并使用从 GeoScene 产品生成的 JSON 对象值对其进行初始化。传入到输入 json 参数的对象通常来自对 REST API 中查询操作的响应或来自另一个 GeoScene 产品的 toJSON() 方法。有关何时以及如何使用该函数的详细信息和示例,请参阅指南中的使用 fromJSON() 主题。

参数
json Object

GeoScene 格式实例的 JSON 表示。有关各种输入 JSON 对象的结构示例,请参阅 GeoScene REST API 文档

返回
类型 描述

返回
类型 描述
Boolean 如果存在指定的句柄组,则返回 true
示例
// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {

}
removeHandles(groupKey)inherited
起始版本:GeoScene Maps SDK for JavaScript 4.25

移除对象拥有的句柄组。

参数

optional

要移除的组键或组键的数组或集合。

示例
obj.removeHandles(); // removes handles from default group

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");
