 # ImageKnife
 
-**专门为OpenHarmony打造的一款图像加载缓存库，致力于更高效、更轻便、更简单。**
+ImageKnife is a specially crafted image loading and caching library for OpenHarmony, optimized for efficiency, lightness, and simplicity.
 
-## 简介
+## Introduction
 
-本项目参考开源库 [Glide](https://github.com/bumptech/glide) 进行OpenHarmony的自研版本：
+This project is a self-developed version for OpenHarmony, inspired by the open-source [Glide](https://github.com/bumptech/glide) library. It sports the following features:
 
-- 支持自定义内存缓存策略，支持设置内存缓存的大小(默认LRU策略)。
-- 支持磁盘二级缓存，对于下载图片会保存一份至磁盘当中。
-- 支持自定义实现图片获取/网络下载
-- 支持监听网络下载回调进度
-- 继承Image的能力，支持option传入border，设置边框，圆角
-- 继承Image的能力，支持option传入objectFit设置图片缩放，包括objectFit为auto时根据图片自适应高度
-- 支持通过设置transform缩放图片
-- 并发请求数量，支持请求排队队列的优先级
-- 支持生命周期已销毁的图片，不再发起请求
-- 自定义缓存key
-- 自定义http网络请求头
-- 支持writeCacheStrategy控制缓存的存入策略(只存入内存或文件缓存)
-- 支持preLoadCache预加载图片
-- 支持onlyRetrieveFromCache仅用缓存加载
-- 支持使用一个或多个图片变换，如模糊，高亮等
+- Customizable memory cache strategy with adjustable cache size (default LRU)
+- Disk L2 cache for downloaded images
+- Custom implementation for image acquisition and network downloading
+- Listening for progress of network downloads through callbacks
+- Image options for borders and rounded corners
+- Image scaling with **objectFit**, including auto-adapting height
+- Image scaling through transformation
+- Concurrent request management with priority queuing
+- No requests made for images whose lifecycle has been destroyed
+- Custom cache keys
+- Custom HTTP request headers
+- **writeCacheStrategy** for controlling cache storage (memory or file)
+- Preloading images with **preLoadCache**
+- Loading images exclusively from cache with **onlyRetrieveFromCache**
+- Support for image transformations such as blurring and highlighting
 
-待实现特性
+Planned features:
 
-- 内存降采样优化，节约内存的占用
-- 支持自定义图片解码
+- Memory downsampling optimization to save memory usage
+- Support for custom image decoding
 
-注意：3.x版本相对2.x版本做了重大的重构，主要体现在：
+Note: The 3.x version has been significantly restructured from the 2.x version, mainly in the following aspects:
 
-- 使用Image组件代替Canvas组件渲染
-- 重构Dispatch分发逻辑，支持控制并发请求数，支持请求排队队列的优先级
-- 支持通过initMemoryCache自定义策略内存缓存策略和大小
-- 支持option自定义实现图片获取/网络下载
+- Use of the **Image** component instead of the **Canvas** component for rendering
+- Refactored dispatch logic to control the number of concurrent requests and support priority in request queuing
+- Support for custom memory cache strategies and sizes through **initMemoryCache**
+- Support for custom implementation of image acquisition/network downloading through options
 
-因此API及能力上，目前有部分差异，主要体现在：
+Therefore, there are some differences in APIs and capabilities, which mainly include the following:
 
-- 不支持drawLifeCycle接口，通过canvas自会图片
-- mainScaleType，border等参数，新版本与系统Image保持一致
-- gif/webp动图播放与控制(ImageAnimator实现)
-- 抗锯齿相关参数
+- The **drawLifeCycle** API is not supported; images are drawn manually through the canvas.
+- In the new version, parameters such as **mainScaleType** and **border** are consistent with the system **Image** component.
+- GIF/WebP animation playback and control (implemented by **ImageAnimator**).
+- Anti-aliasing related parameters.
 
-## 下载安装

-#### 9.ImageKnifeComponent - syncLoad
-设置是否同步加载图片，默认是异步加载。建议加载尺寸较小的本地图片时将syncLoad设为true，因为耗时较短，在主线程上执行即可
+#### 9. Use of syncLoad
+**syncLoad** sets whether to load the image synchronously. By default, the image is loaded asynchronously. When loading a small image, you are advised to set **syncLoad** to **true** so that the image loading can be quickly completed on the main thread.

-## 下载安装GPUImage依赖
-方法一：在Terminal窗口中，执行如下命令安装三方包，DevEco Studio会自动在工程的oh-package.json5中自动添加三方包依赖。
+## Downloading and Installing the GPUImage Dependency
+Method 1: In the **Terminal** window, run the following command to install the third-party HAR. DevEco Studio will automatically add the HAR as a dependency to the **oh-package.json5** file of the project.
 ```
     ohpm install @ohos/gpu_transform
 ```
-方法二： 在工程的oh-package.json5中设置三方包依赖，配置示例如下：
+Method 2: Set the third-party HAR as a dependency in the **oh-package.json5** file of the project. The following is a configuration example:
 ```
     "dependencies": {
       "@ohos/gpu_transform": "^1.0.2"
     }
 ```

+# ImageKnife
+
+**专门为OpenHarmony打造的一款图像加载缓存库，致力于更高效、更轻便、更简单。**
+
+## 简介
+
+本项目参考开源库 [Glide](https://github.com/bumptech/glide) 进行OpenHarmony的自研版本：
+
+- 支持自定义内存缓存策略，支持设置内存缓存的大小(默认LRU策略)。
+- 支持磁盘二级缓存，对于下载图片会保存一份至磁盘当中。
+- 支持自定义实现图片获取/网络下载
+- 支持监听网络下载回调进度
+- 继承Image的能力，支持option传入border，设置边框，圆角
+- 继承Image的能力，支持option传入objectFit设置图片缩放，包括objectFit为auto时根据图片自适应高度
+- 支持通过设置transform缩放图片
+- 并发请求数量，支持请求排队队列的优先级
+- 支持生命周期已销毁的图片，不再发起请求
+- 自定义缓存key
+- 自定义http网络请求头
+- 支持writeCacheStrategy控制缓存的存入策略(只存入内存或文件缓存)
+- 支持preLoadCache预加载图片
+- 支持onlyRetrieveFromCache仅用缓存加载
+- 支持使用一个或多个图片变换，如模糊，高亮等
+
+待实现特性
+
+- 内存降采样优化，节约内存的占用
+- 支持自定义图片解码
+
+注意：3.x版本相对2.x版本做了重大的重构，主要体现在：
+
+- 使用Image组件代替Canvas组件渲染
+- 重构Dispatch分发逻辑，支持控制并发请求数，支持请求排队队列的优先级
+- 支持通过initMemoryCache自定义策略内存缓存策略和大小
+- 支持option自定义实现图片获取/网络下载
+
+因此API及能力上，目前有部分差异，主要体现在：
+
+- 不支持drawLifeCycle接口，通过canvas自会图片
+- mainScaleType，border等参数，新版本与系统Image保持一致
+- gif/webp动图播放与控制(ImageAnimator实现)
+- 抗锯齿相关参数
+
+## 下载安装
+
+```
+ohpm install @ohos/imageknife
+
+// 如果需要用文件缓存，需要提前初始化文件缓存
+await ImageKnife.getInstance().initFileCache(context, 256, 256 * 1024 * 1024)
+```
+
+## 使用说明
+
+#### 1.显示本地资源图片
+
+```
+ImageKnifeComponent({
+  ImageKnifeOption: {
+    loadSrc: $r("app.media.app_icon"),
+    placeholderSrc: $r("app.media.loading"),
+    errorholderSrc: $r("app.media.app_icon"),
+    objectFit: ImageFit.Auto
+  }
+}).width(100).height(100)
+```
+
+#### 2.显示本地context files下文件
+
+```
+ImageKnifeComponent({
+  ImageKnifeOption: {
+    loadSrc: this.localFile,
+    placeholderSrc: $r("app.media.loading"),
+    errorholderSrc: $r("app.media.app_icon"),
+    objectFit: ImageFit.Auto
+  }
+}).width(100).height(100)
+```
+
+#### 3.显示网络图片
+
+```
+ImageKnifeComponent({
+  ImageKnifeOption: {
+    loadSrc:"https://www.openharmony.cn/_nuxt/img/logo.dcf95b3.png",
+    placeholderSrc: $r("app.media.loading"),
+    errorholderSrc: $r("app.media.app_icon"),
+    objectFit: ImageFit.Auto
+  }
+}).width(100).height(100)
+```
+
+#### 4.自定义下载图片
+
+```
+ImageKnifeComponent({
+  ImageKnifeOption: {
+    loadSrc: "https://file.atomgit.com/uploads/user/1704857786989_8994.jpeg",
+    placeholderSrc: $r("app.media.loading"),
+    errorholderSrc: $r("app.media.app_icon"),
+    objectFit: ImageFit.Auto,
+    customGetImage: custom
+ }
+}).width(100).height(100)
+
+// 自定义实现图片获取方法，如自定义网络下载
+@Concurrent
+async function custom(context: Context, src: string | PixelMap | Resource): Promise<ArrayBuffer | undefined> {
+  console.info("ImageKnife::  custom download：" + src)
+  // 举例写死从本地文件读取，也可以自己请求网络图片
+  return context.resourceManager.getMediaContentSync($r("app.media.bb").id).buffer as ArrayBuffer
+}
+```
+
+#### 5.监听网络下载进度
+
+```
+ImageKnifeComponent({
+  ImageKnifeOption: {
+    loadSrc:"https://www.openharmony.cn/_nuxt/img/logo.dcf95b3.png",
+    progressListener:(progress:number)=>{console.info("ImageKinfe:: call back progress = " + progress)}
+  }
+}).width(100).height(100)
+```
+
+#### 6.支持option传入border，设置边框，圆角
+
+```
+ImageKnifeComponent({ ImageKnifeOption: 
+{
+   loadSrc: $r("app.media.rabbit"),
+   border: {radius:50}
+  }
+}).width(100).height(100)
+```
+
+#### 7.支持option图片变换
+
+```
+ImageKnifeComponent({ ImageKnifeOption: 
+{
+   loadSrc: $r("app.media.rabbit"),
+   border: {radius:50},
+   transformation: new BlurTransformation(3)
+  }
+}).width(100).height(100)
+```
+多种组合变换用法
+
+```
+let transformations: collections.Array<PixelMapTransformation> = new collections.Array<PixelMapTransformation>();
+transformations.push(new BlurTransformation(5));
+transformations.push(new BrightnessTransformation(0.2));
+ImageKnifeComponent({
+  imageKnifeOption: {
+  loadSrc: $r('app.media.pngSample'),
+  placeholderSrc: $r("app.media.loading"),
+  errorholderSrc: $r("app.media.app_icon"),
+  objectFit: ImageFit.Contain,
+  border: { radius: { topLeft: 50, bottomRight: 50 } }, // 圆角设置
+  transformation: transformations.length > 0 ? new MultiTransTransformation(transformations) : undefined // 图形变换组
+}
+}).width(300)
+  .height(300)
+  .rotate({ angle: 90 }) // 旋转90度
+  .contrast(12) // 对比度滤波器
+```
+其它变换相关属性，可叠加实现组合变换效果
+
+圆形裁剪变换示例
+
+```
+ImageKnifeComponent({ ImageKnifeOption: 
+  {
+  loadSrc: $r('app.media.pngSample'),
+  objectFit: ImageFit.Cover,
+  border: { radius: 150 }
+}
+}).width(300)
+  .height(300)
+```
+
+圆形裁剪带边框变换示例
+
+```
+ImageKnifeComponent({ ImageKnifeOption: 
+  {
+  loadSrc: $r('app.media.pngSample'),
+  objectFit: ImageFit.Cover,
+  border: { radius: 150, color: Color.Red, width: 5 }
+}
+}).width(300)
+  .height(300)
+```
+
+对比度滤波变换示例
+
+```
+ImageKnifeComponent({
+  imageKnifeOption: {
+    loadSrc: $r('app.media.pngSample')
+  }
+}).width(300)
+  .height(300)
+  .contrast(12)
+```
+
+旋转变换示例
+
+```
+ImageKnifeComponent({
+  imageKnifeOption:  {
+    loadSrc: $r('app.media.pngSample')
+  }
+}).width(300)
+  .height(300)
+  .rotate({angle:90})
+  .backgroundColor(Color.Pink)
+```
+
+#### 8.监听图片加载成功与失败
+
+```
+ImageKnifeComponent({ ImageKnifeOption: 
+{
+   loadSrc: $r("app.media.rabbit"),
+   onLoadListener:{
+    onLoadStart:()=>{
+     this.starTime = new Date().getTime()
+     console.info("Load start: ");
+    },
+    onLoadFailed: (err) => {
+     console.error("Load Failed Reason: " + err + "  cost " + (new Date().getTime() - this.starTime) + " milliseconds");
+    },
+    onLoadSuccess: (data, imageData) => {
+     console.info("Load Successful: cost " + (new Date().getTime() - this.starTime) + " milliseconds");
+     return data;
+    },
+    onLoadCancel(err){
+      console.info(err)
+    }
+   }
+ }
+}).width(100).height(100)
+```
+#### 9.ImageKnifeComponent - syncLoad
+设置是否同步加载图片，默认是异步加载。建议加载尺寸较小的Resource图片时将syncLoad设为true，因为耗时较短，在主线程上执行即可
+```
+ImageKnifeComponent({
+        imageKnifeOption:{
+          loadSrc:$r("app.media.pngSample"),
+          placeholderSrc:$r("app.media.loading")

+```
+ImageKnifeComponent({ ImageKnifeOption: = {
+                loadSrc: $r('app.media.pngSample'),
+                objectFit: ImageFit.Contain,
+                onLoadListener: {
+                  onLoadStart: (req) => {
+                    let startCallBackData = JSON.stringify(req?.imageKnifeData);
+                  },
+                  onLoadFailed: (res, req) => {
+                    let failedBackData = res + ";" + JSON.stringify(req?.imageKnifeData);

+                  onLoadCancel: (res, req) => {
+                    let cancelBackData = res + ";" + JSON.stringify(req?.imageKnifeData);
+                  }
+                },
+                border: { radius: 50 },
+                onComplete: (event) => {
+                  if (event && event.loadingStatus == 0) {
+                    let render_success = JSON.stringify(Date.now())
+                  }
+                }
+              }
+}).width(100).height(100)
+```
+#### 12.图片降采样 示例
+```
+ImageKnifeComponent({
+        imageKnifeOption:{
+          loadSrc:$r("app.media.pngSample"),
+          placeholderSrc:$r('app.media.loading'),
+          errorholderSrc:$r('app.media.failed'),
+          downsampleOf: DownsampleStrategy.NONE
+        }
+      }).width(300).height(300)
+```
+#### 13.rcp自定义网络请求
+```
+ImageKnifeComponent({
+    loadSrc:"http//xx.xx",
+    customGetImage:custom
+})
+// 自定义下载方法
+@Concurrent
+async function custom(context: Context, src: string | PixelMap | Resource,headers?: Record<string,Object>): Promise<ArrayBuffer | undefined> {
+  return new Promise((resolve,reject)=>{
+    if (typeof src == "string") {
+      let session = GetSession.session
+      let req = new rcp.Request(src,"GET");
+      session.fetch(req).then((response)=>{
+        if(response.statusCode == 200) {
+          let buffer = response.body
+          resolve(buffer)
+        } else {
+          reject("rcp code:"+response.statusCode)
+        }
+      }).catch((err:BusinessError)=>{
+        reject("error rcp src:"+src+",err:"+JSON.stringify(err))
+      })
+    }
+  })

+## 下载安装GPUImage依赖
+方法一：在Terminal窗口中，执行如下命令安装三方包，DevEco Studio会自动在工程的oh-package.json5中自动添加三方包依赖。
+```
+    ohpm install @ohos/gpu_transform
+```
+方法二： 在工程的oh-package.json5中设置三方包依赖，配置示例如下：
+```
+    "dependencies": {
+      "@ohos/gpu_transform": "^1.0.2"
+    }
+```
+## 约束与限制
+
+在下述版本验证通过：  
+DevEco Studio: NEXT Beta1-5.0.3.806, SDK: API12 Release(5.0.0.66)
+
