## 下载安装 ## 下载安装
``` ```
ohpm install @ohos/imageknife ohpm install @ohos/imageknife
``` ```
## 使用说明 ## 使用说明
#### 1.显示本地资源图片
### 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： ImageKnifeComponent({
ImageKnifeOption: {
```typescript src: $r("app.media.app_icon"),
import UIAbility from '@ohos.app.ability.UIAbility'; placeholderSrc: $r("app.media.loading"),
import window from '@ohos.window'; errorholderSrc: $r("app.media.app_icon"),
import { ImageKnife } from '@ohos/imageknife' objectFit: ImageFit.Auto
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
} }
}).width(100).height(100)
```
#### 2.显示本地context files下文件
```
ImageKnifeComponent({
ImageKnifeOption: {
src: 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: {
src:"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: {
src: "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
} }
``` ```
### 2.加载普通图片 #### 5.监听网络下载进度
接下来我们来写个简单实例看看:
```extendtypescript
import { ImageKnifeComponent, ImageKnifeOption } from '@ohos/imageknife'
@Entry
@Component
struct Index {
@State message: string = 'Hello World'
@State option: ImageKnifeOption = {
loadSrc: $r('app.media.icon')
}
build() {
Row() {
Column() {
Text(this.message)
.fontSize(50)
.fontWeight(FontWeight.Bold)
ImageKnifeComponent({ imageKnifeOption: this.option })
.width(300)
.height(300)
}.width('100%')
}.height('100%')
}
}
``` ```
ImageKnifeComponent({
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。 ImageKnifeOption: {
src:"https://www.openharmony.cn/_nuxt/img/logo.dcf95b3.png",
### 3.加载SVG图片 progressListener:(progress:number)=>{console.info("ImageKinfe:: call back progress = " + progress)}
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。
### 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())
} }
}).width(100).height(100)
``` ```
详细样例请参考SignatureTestPage文件 #### 6.支持option传入border，设置边框，圆角
代码示例
## 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。
### ImageKnifeOption参数列表
| 参数名称 | 入参内容 | 功能简介 |
| ---------------------------- | ------------------------------------------------------------ |-----------------------------------------------|
| loadSrc | string\| PixelMap\ |Resource | 图片数据源 |
| mainScaleType | ScaleType | 设置主图展示样式（可选） |
| strategy | DiskStrategy | 设置磁盘缓存策略（可选） |
| dontAnimateFlag | boolean | gif加载展示一帧（可选） |
| placeholderSrc | PixelMap\| Resource | 占位图数据源 |
| placeholderScaleType | ScaleType | 设置占位图展示样式（可选） |
| errorholderSrc | PixelMap\| Resource | 错误占位图数据源 |
| errorholderSrcScaleType | ScaleType | 设置失败占位图展示样式（可选） |
| retryholderSrc | PixelMap\| Resource | 重试占位图数据源 |

| thumbSizeMultiplier | number 范围(0,1] | 设置缩略图占比（可选） |
| thumbSizeDelay | number | 设置缩略图展示时间（可选） |
| thumbSizeMultiplierScaleType | ScaleType | 设置缩略图展示样式（可选） |
| displayProgress | boolean | 设置是否展示下载进度条（可选） |
| canRetryClick | boolean | 设置重试图层是否点击重试（可选） |
| onlyRetrieveFromCache | boolean | 仅使用缓存加载数据（可选） |
| isCacheable | boolean | 是否开启一级内存缓存（可选） |
| gif | {<br/> // 返回一周期动画gif消耗的时间<br/> loopFinish?: (loopTime?) => void<br/> // gif播放速率相关<br/> speedFactory?: number<br/> // 直接展示gif第几帧数据<br/> seekTo?: number<br/> } | GIF播放控制能力（可选） |
| transformation | BaseTransform<PixelMap> | 单个变换（可选） |
| transformations | Array<BaseTransform<PixelMap>> | 多个变换,目前仅支持单个变换（可选） |
| allCacheInfoCallback | IAllCacheInfoCallback | 输出缓存相关内容和信息（可选） |
| signature | ObjectKey | 自定key（可选） |
| **drawLifeCycle** | **IDrawLifeCycle** | **用户自定义实现绘制方案（可选）** |
| imageSmoothingEnabled | boolean | 抗锯齿是否开启属性配置，设置为false时，imageSmoothingQuality失效 |
| imageSmoothingQuality | AntiAliasing | 抗锯齿属性配置 |
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。
<img src="screenshot/png2.png" width="70%"/>
### 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%')
}
}
``` ```
ImageKnifeComponent({ ImageKnifeOption:
`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。 src: $r("app.media.rabbit"),
border: {radius:50}
*
*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))
} }
} }).width(100).height(100)
```
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
```
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)
}
```
**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(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。
**参数：**
| 参数名 | 类型 | 必填 | 说明 |
| -------- | -------- | -------- |-------------------------|
| 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 |
**示例：**
```ts
//EntryAbility.ets
import { InitImageKnife } from '...imageknife'
export default class EntryAbility extends UIAbility {
onWindowStageCreate(windowStage: window.WindowStage) {
InitImageKnife.init(this.context);
let imageKnife: ImageKnife | undefined = ImageKnifeGlobal.getInstance().getImageKnife()
if (imageKnife != undefined) {
//设置全局内存缓存大小张数
imageKnife.setLruCacheSize(100, 100 * 1204 * 1024)
}
}
}
``` ```

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。
