+# Image白块解决指导
+
+### 简介
+
+本示例主要解决使用原生Image组件加载大的网络图片时，出现长时间Image白块的问题。
+
+| 效果预览                                   |
+|----------------------------------------|
+| <img src="screenshots/devices/show.gif" width="300"> |
+
+
+### 使用说明
+
+1、父页面点击"push Path to pageOne"按钮，跳转子页面PageOne。
+
+2、子页面展示网络图片，无明显的长时间白块现象。
+
+### 工程目录
+```
+├──entry/src/main/ets
+│  ├──entryability
+│  │  └──EntryAbility.ets                   // 程序入口类
+│  ├──pages
+│  │  ├──MainPage.ets                       // 视图层-父页面
+│  │  └──PageOne.ets                        // 视图层-子页面
+│  └──utils
+│     ├──Logger.ets                         // 日志工具类
+│     └──NetRequest.ets                     // 网络请求类
+└──entry/src/main/resources                 // 应用静态资源目录
+```
+
+### 具体实现
+
+1. 在父组件aboutToAppear()中提前发起网络请求，当父页面点击按钮跳转子页面PageOne，此时触发pixMap请求读取应用沙箱中已缓存解码的网络图片并存储在localStorage中，非首次点击时，不再重复调用getPixMap()，避免每次点击都从沙箱里读取文件。
+2. 在NetRequest.ets中定义网络请求httpRequest()，通过fs.access()检查文件是否存在，当文件存在时不再重复请求，并写入沙箱中。
+3. 在子组件里：通过在子组件Image中传入被@StorageLink修饰的变量ImageData进行数据刷新，图片送显。
+4. 从而通过提前预下载的方式，解决使用Image原生组件加载大的网络图片时，出现长时间Image白块的问题。
+
+### 相关权限
+
+网络权限：ohos.permission.INTERNET
+
+### 依赖
+
+不涉及。
+
+### 约束与限制
+
+1. 本示例仅支持标准系统上运行，支持设备：华为手机。
+2. HarmonyOS系统：HarmonyOS NEXT Beta1及以上。
+3. DevEco Studio版本：DevEco Studio NEXT Beta1及以上。
+4. HarmonyOS SDK版本：HarmonyOS NEXT Beta1 SDK及以上。
