 # 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
 
-本项目基于开源库 [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:
 
-- 支持内存缓存，使用LRUCache算法，对图片数据进行内存缓存。
-- 支持磁盘缓存，对于下载图片会保存一份至磁盘当中。
-- 支持进行图片变换: 支持图像像素源图片变换效果。
-- 支持用户配置参数使用:(
-  例如：配置是否开启一级内存缓存，配置磁盘缓存策略，配置仅使用缓存加载数据，配置图片变换效果，配置占位图，配置加载失败占位图等)。
-- 推荐使用ImageKnifeComponent组件配合ImageKnifeOption参数来实现功能。
-- 支持用户自定义配置实现能力参考ImageKnifeComponent组件中对于入参ImageKnifeOption的处理。
+- 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
 
-<img src="screenshot/gif1.gif" width="50%"/>
+Planned features:
 
-## 下载安装
+- Memory downsampling optimization to save memory usage
+- Support for custom image decoding
+
+Note: The 3.x version has been significantly restructured from the 2.x version, mainly in the following aspects:
+
+- 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
+
+Therefore, there are some differences in APIs and capabilities, which mainly include the following:
+
+- 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.
+
+## How to Install
 
 ```
 ohpm install @ohos/imageknife
+
+// If file caching is required, initialize the file cache in advance.
+await ImageKnife.getInstance().initFileCache(context, 256, 256 * 1024 * 1024)
 ```
 
-## 使用说明  
+## How to Use
 
-### 1.依赖配置
-在entry\src\main\ets\entryability\EntryAbility.ts中做如下配置初始化全局ImageKnife实例：
+#### 1. Displaying a Local Resource Image
 
-```typescript
-import UIAbility from '@ohos.app.ability.UIAbility';
-import window from '@ohos.window';
-import { ImageKnife } from '@ohos/imageknife'
-
-export default class EntryAbility extends UIAbility {
-  onWindowStageCreate(windowStage: window.WindowStage) {
-    windowStage.loadContent('pages/Index', (err, data) => {
-    });
-    // 初始化全局ImageKnife 
-    ImageKnife.with(this.context);
-  	// 后续访问ImageKnife请通过:ImageKnifeGlobal.getInstance().getImageKnife()方式
+```
+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.加载普通图片
+#### 2. Displaying a File from Local Context Files
 
-接下来我们来写个简单实例看看:
-
-```extendtypescript
-import { ImageKnifeComponent, ImageKnifeOption } from '@ohos/imageknife'

+#### 3. Displaying a Network Image
+
+```
+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)
 ```
 
-非常简单，仅需定义一个ImageKnifeOption数据对象，然后在你需要的UI位置，加入ImageKnifeComponent自定义组件就可以加载出一张图像了。
-
-### 3.加载SVG图片
-
-加载svg其实和普通流程没有区别,只要将 `loadSrc: $r('app.media.jpgSample'),` `改成一张 loadSrc: $r('app.media.svgSample'),`
-svg类型图片即可。
-
-
-### 4.加载GIF图片
-
-加载GIF其实和普通流程也没有区别只要将 `loadSrc: $r('app.media.jpgSample'),` `改成一张 loadSrc: $r('app.media.gifSample'),`
-GIF图片即可。
-
-#### 4.1加载GIF图片
-
-更改ImageKnifeOption对象的autoPlay（可选autoPlay = true为开始播放，autoPlay = false为暂停播放）
-
-### 5.自定义Key
-因为通常改变标识符比较困难或者根本不可能，所以ImageKnife也提供了 签名 API 来混合（你可以控制的）额外数据到你的缓存键中。
-签名(signature)适用于媒体内容，也适用于你可以自行维护的一些版本元数据。
-
-将签名传入加载请求
-```extendtypescript
-imageKnifeOption = {
-                loadSrc: 'https://aahyhy.oss-cn-beijing.aliyuncs.com/blue.jpg',
-                signature: new ObjectKey(new Date().getTime().toString())
-              }
-```
-详细样例请参考SignatureTestPage文件
-
-代码示例
-
-### 6.自定义请求头规格
-设置全局header并且设置request的header时，当key不同时全局和request并行，当key相同时request的header覆盖全局的header
-
-## 进阶使用
-
-如果简单的加载一张图像无法满足需求，我们可以看看ImageKnifeOption这个类提供了哪些扩展能力。

-其他参数只需要在ImageKnifeOption对象上按需添加即可。
-
-这里我们着重讲一下**自定义实现绘制方案**。为了增强绘制扩展能力，目前ImageKnifeComponent使用了Canvas的渲染能力作为基础。在此之上为了抽象组件绘制表达。我将图像的状态使用了
-**IDrawLifeCycle绘制生命周期进行表达**，
-
-大致流程 展示占位图->展示网络加载进度->展示缩略图->展示主图->展示重试图层->展示失败占位图
-
-<img src="screenshot/png1.png" width="100%"/>
-
-ImageKnifeComponent内部，责任链实现。 用户参数设置->全局参数设置->自定义组件内部设置
-
-采用责任链的好处是，用户可以通过自定义绘制，重新绘制图层。如果不想绘制也可以通过预制回调获取绘制流程信息。

-
-### 场景1:默认的展示不满足需求，需要加个圆角效果。
-
-代码如下:
-
-```typescript
-import { ImageKnifeComponent } from '@ohos/imageknife'
-import { ImageKnifeOption } from '@ohos/imageknife'
-import { ImageKnifeDrawFactory } from '@ohos/imageknife'
-
-@Entry
-@Component
-struct Index {
-  @State imageKnifeOption1: ImageKnifeOption = { 
-      // 加载一张本地的jpg资源（必选）
-      loadSrc: $r('app.media.jpgSample'),
-      // 占位图使用本地资源icon_loading（可选）
-      placeholderSrc: $r('app.media.icon_loading'),
-      // 失败占位图使用本地资源icon_failed（可选）
-      errorholderSrc: $r('app.media.icon_failed'),
-      // 绘制圆角30，边框5，边框"#ff00ff".用户自定义绘制（可选）
-      drawLifeCycle:ImageKnifeDrawFactory.createRoundLifeCycle(5,"#ff00ff",30)
-    };
-        
-    build(){
-        Scroll() {
-          Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
-            ImageKnifeComponent({ imageKnifeOption: this.imageKnifeOption1 })
-            .width(300) 
-            .height(300)
-          }
-        }
-        .width('100%')
-        .height('100%')
-    }
-}
-```
-
-`ImageKnifeDrawFactory.createRoundLifeCycle(5,"#ff00ff",30)`
-我们深入查看源码可以发现，实际上是对IDrawLifeCycle接口的部分实现，这里我介绍一下IDrawLifeCycle。
-
-*
-*IDrawLifeCycle的返回值代表事件是否被消费，如果被消费接下来组件内部就不会处理，如果没被消费就会传递到下一个使用者。目前消费流程（用户自定义->
-全局配置定义->组件内部默认定义）**
-
-所以我们在当数据是一张PixelMap的时候（目前jpg png bmp webp
-svg返回的都是PixelMap，gif返回GIFFrame数组），我们返回了true。消费了事件，代表这个绘制流程用户自定义完成。
-
-<img src="screenshot/gif2.gif" width="50%"/>
-
-由于IDrawLifeCycle实现较为冗长，我们封装了ImageKnifeDrawFactory工厂，提供了网络下载百分比效果、圆角、椭圆添加边框等能力。下面我们就再看看使用工厂封装之后的场景代码。
-
-### 场景2: 网络下载百分比效果展示
-
-当进行加载网络图片时，可能需要展示网络下载百分比动画。但是默认的动画又不能满足需求，这个时候我们就需要自定义网络下载百分比效果。代码如下:
-
-```typescript
-import UIAbility from '@ohos.app.ability.UIAbility';
-import window from '@ohos.window';
-import { ImageKnifeGlobal,ImageKnife,ImageKnifeDrawFactory,LogUtil } from '@ohos/imageknife'
-import abilityAccessCtrl,{Permissions} from '@ohos.abilityAccessCtrl';
-export default class EntryAbility extends UIAbility {
-    onWindowStageCreate(windowStage: window.WindowStage) {
-        //.. 删除不必要代码
-        windowStage.loadContent('pages/index', (err, data) => {
-        });
-       	// 初始化ImageKnifeGlobal和ImageKnife
-        ImageKnife.with(this.context);
-        // 全局配置网络加载进度条 使用ImageKnifeGlobal.getInstance().getImageKnife()访问ImageKnife
-ImageKnifeGlobal.getInstance().getImageKnife().setDefaultLifeCycle(ImageKnifeDrawFactory.createProgressLifeCycle("#10a5ff", 0.5))
-    }
-}
-```
-
-这里大家可能会问，为什么会将这个IDrawLifeCycle放在AbilityStage里面实现？
-
-这是因为网络下载百分比进度很多时候都是全局通用，如果有需要全局配置的自定义展示方案。推荐在AbilityStage里面，往ImageKnife的setDefaultLifeCycle函数中注入，即可将ImageKnifeComponent中的默认绘制方案替换。
-
-在这里我们实现的效果如下图所示。
-
-<img src="screenshot/gif3.gif" width="50%"/>
-
-## 高级用法
-
-以上简单使用和进阶使用都是经过一层自定义组件封装之后形成的，RequestOption封装成了ImageKnifeOption,绘制部分封装成了自定义组件ImageKnifeComponent。
-
-如果用户其实并不关心绘制部分，或者说想用自己的通用方案对自定义组件ImageKnifeComponent重构都是可以的。
-
-下面我们会着重指导用户如何复用图片加载逻辑，重构自定义组件ImageKnifeComponent。
-
-首先我们先看看RequestOption构建的内容,如下所示:
-
-### 数据加载
-
-#### RequestOption构建:
-
-请查阅下文接口内容：[RequestOption接口方法](#requestoption用户配置参数)
-
-了解了RequestOption的参数内容后，我们可以参考ImageKnifeComponent组件代码进行分析。
-
-**从`imageKnifeExecute()`函数入口，首先我们需要构建一个RequestOption对象，`let request = new RequestOption()`,
-接下来就是按需配置request对象的内容，最后使用 `ImageKnifeGlobal.getInstance().getImageKnife()?.call(request)`发送request执行任务即可。**
-
-是不是很简单，而其实最重要的内容是就是:  **按需配置request对象的内容** 为了更好理解，我举例说明一下:
-
-#### 场景一: 简单加载一张图片
+#### 4. Downloading an Image with Custom Options
 
 ```
-let request = new RequestOption();
-// (必传)
-request.load("图片url")
-  // (可选 整个request监听回调)
-	.addListener({callback:(err:BusinessError|string, data:ImageKnifeData) => {
-	// data 是ImageKnifeData对象
-	if(data.isPixelMap()){
-	// 这样就获取到了目标PixelMap
-	let pixelmap = data.drawPixleMap.imagePixelMap;
-	}
-    return false;
-  })
- 
-  let compSize:Size = {
-    width: this.currentWidth,
-    height:this.currentHeight
-  }
-  // (必传)这里setImageViewSize函数必传组件大小，因为涉及到图片变换效果都需要适配图像源和组件大小
- request.setImageViewSize(compSize)
- // 最后使用ImageKnife的call函数调用request即可
- let imageKnife:ImageKnife|undefined = ImageKnifeGlobal.getInstance().getImageKnife();
- if(imageKnife != undefined){
- 	imageKnife.call(request)
+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)
 
-```
-
-**其他场景，可以按需加载**
-
-比如我需要配置 **占位图** 只需要 在request对象创建好之后,调用 **placeholder** 函数即可
-
-```
-request.placeholder(this.imageKnifeOption.placeholderSrc, (data) => {
-  console.log('request.placeholder callback')
-  this.displayPlaceholder(data)
-})
-```
-
-再比如 我对缓存配置有要求，我要禁用内存缓存，调用 **skipMemoryCache** 函数即可
-
-```
-request.skipMemoryCache(true)
-```
-
-这里只是简单介绍部分使用，更多的内容请参考 **按需加载** 原则，并且可以参考ImageKnifeComponent源码或者根据文档自行探索实现。

-### setLruCacheSize
-
-setLruCacheSize(size: number,memory:number): void
-
-设置图片文件缓存的大小上限，size单位为张数，memory单位为字节，提升再次加载同源图片的加载速度，特别是对网络图源会有较明显提升。
-如果不设置则默认为100张，100MB。缓存采用内置的LRU策略。
-size为0则代表不限制缓存张数，memory为0则代表不限制缓存大小。
-建议根据应用实际需求，设置合理缓存上限，数字过大可能导致内存占用过高，可能导致OOM异常。
-

-| size | number | 是 | 图片文件的缓存张数，单位为张。只支持正整数，0 |
-| memory | number | 是 | 图片文件的缓存大小，单位为字节。只支持正数，0 |

-
-HSP场景适配:
-
-在使用ImageKnifeComponent进行加载图片时, 提供的ImageKnifeOption配置类新增了可选参数context, 在HSP场景下需要传入正确的context, 才能保证三方库后续正确获取Resource资源。
-
-在使用RquestOption进行加载图片时, 提供的RquestOption配置类新增了接口`setModuleContext(moduleCtx:common.UIAbilityContext)`, 在HSP场景下需要传入正确的context, 才能保证三方库后续正确获取Resource资源。
-
-非HSP场景不影响原功能, ImageKnifeOption配置类新增的可选参数context可以不传, RquestOption配置类新增的接口可以不调用。
-
-注意：
-
-基于性能优化的原因，2.1.2-rc.13及以后版本引用了API12 Sendable接口，至此以后的版本只支持API12。

-使用过程中发现任何问题都可以提 [issue](https://gitee.com/openharmony-tpc/ImageKnife/issues)
-给我们，当然，我们也非常欢迎你给我们发 [PR](https://gitee.com/openharmony-tpc/ImageKnife/issues) 。
+```
+ImageKnifeComponent({ ImageKnifeOption: 
+{
+   loadSrc: $r("app.media.rabbit"),
+   border: {radius:50}
+  }
+}).width(100).height(100)
+```
 
-## 开源协议
+#### 7. Setting Image Transformation Options
 
-本项目基于 [Apache License 2.0](https://gitee.com/openharmony-tpc/ImageKnife/blob/master/LICENSE) ，请自由的享受和参与开源。
+```
+ImageKnifeComponent({ ImageKnifeOption: 
+{
+   loadSrc: $r("app.media.rabbit"),
+   border: {radius:50},
+   transformation: new BlurTransformation(3)
+  }
+}).width(100).height(100)
+```
+Multiple combined transformation usages:
 
-## 遗留问题
+```
+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 } }, // Rounded corner settings
+  transformation: transformations.length > 0 ? new MultiTransTransformation(transformations) : undefined // Graphic transformation group
+}
+}).width(300)
+  .height(300)
+  .rotate ({angle: 90}) // Rotate by 90 degrees.
+  .contrast(12) // Contrast filter
+```
+Other transformation-related properties can be stacked to achieve combined transformation effects.
 
-1.目前只支持一种图片变换效果。
+Example of circular cropping transformation:
 
-2.目前svg和gif动图不支持变换效果。
+```
+ImageKnifeComponent({ ImageKnifeOption:
+  {
+  loadSrc: $r('app.media.pngSample'),
+  objectFit: ImageFit.Cover,
+  border: { radius: 150 }
+}
+}).width(300)
+  .height(300)
+```
 
-## 补充说明
-### SVG标签说明
-使用版本为(SVG)1.1,当前支持的标签列表有：
-- a
-- circla
-- clipPath
-- defs
-- ellipse
-- feBlend
-- feColorMatrix
-- feComposite
-- feDiffuseLighting
-- feDisplacementMap
-- feDistantLight
-- feFlood

-- line
-- linearGradient
-- mask
-- path
-- pattern
-- polygon
-- polyline
-- radialGradient
-- rect
-- stop
-- svg
-- text
-- textPath
-- tspan
-- use
+Example of Circular cropping with border transformation:
+
+```
+ImageKnifeComponent({ ImageKnifeOption:
+  {
+  loadSrc: $r('app.media.pngSample'),
+  objectFit: ImageFit.Cover,
+  border: { radius: 150, color: Color.Red, width: 5 }
+}
+}).width(300)
+  .height(300)
+```
+
+Example of contrast filtering transformation:
+
+```
+ImageKnifeComponent({
+  imageKnifeOption: {
+    loadSrc: $r('app.media.pngSample')
+  }
+}).width(300)
+  .height(300)
+  .contrast(12)
+```
+
+Example of rotation transformation:
+
+```
+ImageKnifeComponent({
+  imageKnifeOption:({
+    loadSrc: $r('app.media.pngSample')
+  }
+}).width(300)
+  .height(300)
+  .rotate({angle:90})
+  .backgroundColor(Color.Pink)
+```
+
+#### 8. Listening for Image Loading Success and Failure
+
+```
+ImageKnifeComponent({ ImageKnifeOption:
+{
+   loadSrc: $r("app.media.rabbit"),
+   onLoadListener:{
+    onLoadStart:()=>{
+     this.starTime = new Date().getTime()
+     console.info("Load start: ");
+    },
+    onLoadFailed: (err) => {
+     console.error("Load Failed Reason: " + err + "  cost " + (new Date().getTime() - this.starTime) + " milliseconds");
+    },
+    onLoadSuccess: (data, imageData) => {
+     console.info("Load Successful: cost " + (new Date().getTime() - this.starTime) + " milliseconds");
+     return data;
+    },
+    onLoadCancel(err){
+      console.info(err)
+    }
+   }
+  }
+}).width(100).height(100)
+```
+#### 9. Use of syncLoad
+**syncLoad** sets whether to load the image synchronously. By default, the image is loaded asynchronously. When loading a small image, you are advised to set **syncLoad** to **true** so that the image loading can be quickly completed on the main thread.
+```
+ImageKnifeComponent({
+        imageKnifeOption:{
+          loadSrc:$r("app.media.pngSample"),
+          placeholderSrc:$r("app.media.loading")
+        },syncLoad:true
+      })
+```
+#### 10. Use of ImageKnifeAnimatorComponent
+```
+ImageKnifeAnimatorComponent({
+        imageKnifeOption:{
+          loadSrc:"https://gd-hbimg.huaban.com/e0a25a7cab0d7c2431978726971d61720732728a315ae-57EskW_fw658",
+          placeholderSrc:$r('app.media.loading'),
+          errorholderSrc:$r('app.media.failed')
+        },animatorOption:this.animatorOption
+      }).width(300).height(300).backgroundColor(Color.Orange).margin({top:30})
+```
+#### Reuse Scenario
+Clear the component content in the **aboutToRecycle** lifecycle and trigger image loading through watch observeration.

+- 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

+@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

+   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'),

+    onLoadCancel(err){
+      console.info(err)
+    }
+   }
+ }
+}).width(100).height(100)
+```
+#### 9.ImageKnifeComponent - syncLoad

+                    let cancelBackData = res + ";" + JSON.stringify(req?.imageKnifeData);
+                  }
+                },
+                border: { radius: 50 },
+                onComplete: (event) => {
+                  if (event && event.loadingStatus == 0) {
+                    let render_success = JSON.stringify(Date.now())
+                  }
+                }
+              }

+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)
+
+## 关于混淆
+- 代码混淆，请查看[代码混淆简介](https://docs.openharmony.cn/pages/v5.0/zh-cn/application-dev/arkts-utils/source-obfuscation.md)
+- 如果希望imageknife库在代码混淆过程中不会被混淆，需要在混淆规则配置文件obfuscation-rules.txt中添加相应的排除规则：
+
+```
+-keep
+./oh_modules/@ohos/imageknife
+```
