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

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. 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

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:$r("app.media.loading")
},syncLoad:true
})
```
#### 10.ImageKnifeAnimatorComponent 示例
```
ImageKnifeAnimatorComponent({
imageKnifeOption: {
loadSrc:"https://gd-hbimg.huaban.com/e0a25a7cab0d7c2431978726971d61720732728a315ae-57EskW_fw658",
placeholderSrc:$r('app.media.loading'),
errorholderSrc:$r('app.media.failed')
},animatorOption:this.animatorOption
}).width(300).height(300).backgroundColor(Color.Orange).margin({top:30})
```
#### 11.加载图片回调信息数据 示例
```
ImageKnifeComponent({ ImageKnifeOption: = {
loadSrc: $r('app.media.pngSample'),
objectFit: ImageFit.Contain,
onLoadListener: {
onLoadStart: (req) => {
let startCallBackData = JSON.stringify(req?.imageKnifeData);
},
onLoadFailed: (res, req) => {
let failedBackData = res + ";" + JSON.stringify(req?.imageKnifeData);
},
onLoadSuccess: (data, imageData, req) => {
let successBackData = JSON.stringify(req?.imageKnifeData);
},
onLoadCancel: (res, req) => {
let cancelBackData = res + ";" + JSON.stringify(req?.imageKnifeData);
}
},
border: { radius: 50 },
onComplete: (event) => {
if (event && event.loadingStatus == 0) {
let render_success = JSON.stringify(Date.now())
}
}
}
}).width(100).height(100)
```
#### 12.图片降采样 示例
```
ImageKnifeComponent({
imageKnifeOption:{
loadSrc:$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))
})
}
})
}
```
#### 复用场景
在aboutToRecycle生命周期清空组件内容；通过watch监听触发图片的加载。

## 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
```

使用过程中发现任何问题都可以提 [issue](https://gitee.com/openharmony-tpc/ImageKnife/issues)
，当然，也非常欢迎发 [PR](https://gitee.com/openharmony-tpc/ImageKnife/pulls) 共建。
