## 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)
```
## X86模拟器配置
## 使用说明
[使用模拟器运行应用/服务](https://developer.huawei.com/consumer/cn/deveco-developer-suite/enabling/kit?currentPage=1&pageSize=100)
#### 1.显示本地资源图片
## 使用说明
### 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
```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.显示本地context files下文件
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')
```
ImageKnifeComponent({
ImageKnifeOption: {
loadSrc: this.localFile,
placeholderSrc: $r("app.media.loading"),
errorholderSrc: $r("app.media.app_icon"),
objectFit: ImageFit.Auto
}
}).width(100).height(100)
```
build() {
Row() {
Column() {
Text(this.message)
.fontSize(50)
.fontWeight(FontWeight.Bold)
ImageKnifeComponent({ imageKnifeOption: this.option })
.width(300)
.height(300)
}.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)
```
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。
#### 4.自定义下载图片
### 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。
注:SVG文件需添加xml声明,应以"<?xml"开头,并且SVG标签需设置width, height。
### 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
### 7.自定义网络栈加载图片
7.1 自定义网络栈加载单个图片在imageKnifeNextOption中添加customGetImage标签然后完善custom函数的逻辑即可
```
ImageKnifeNextComponent({
imageKnifeNextOption: {
loadSrc: 'http://e.hiphotos.baidu.com/image/pic/item/4e4a20a4462309f7e41f5cfe760e0cf3d6cad6ee.jpg',
placeholderSrc: $r('app.media.icon_loading'),
errorholderSrc: $r('app.media.icon_failed'),
customGetImage: custom
ImageKnifeComponent({
ImageKnifeOption: {
loadSrc: "https://file.atomgit.com/uploads/user/1704857786989_8994.jpeg",
placeholderSrc: $r("app.media.loading"),
errorholderSrc: $r("app.media.app_icon"),
objectFit: ImageFit.Auto,
customGetImage: custom
}
}).width(100).height(100)
// 自定义实现图片获取方法,如自定义网络下载
@Concurrent
async function custom(context: Context, src: string): Promise<ArrayBuffer | undefined> {
let result: DataFetchResult = new DataFetchResult();
result.data = arraybuffer; //此处替换成自己网络获取的ArrayBuffer的逻辑
return result;
async function custom(context: Context, src: string | PixelMap | Resource): Promise<ArrayBuffer | undefined> {
console.info("ImageKnife:: custom download" + src)
// 举例写死从本地文件读取,也可以自己请求网络图片
return context.resourceManager.getMediaContentSync($r("app.media.bb").id).buffer as ArrayBuffer
}
```
7.2 自定义网络栈加载全部图片
```
1.先执行ImageKnifeGlobal.getInstance().getImageKnife()?.replaceDataFetch(new CustomDataFetchClient()); 替换网络栈
2.在CustomDataFetchClient这个类中也通过下面的逻辑替换成自己网络获取的ArrayBuffer的逻辑
let result: DataFetchResult = new DataFetchResult();
result.data = arraybuffer; //此处替换成自己网络获取的ArrayBuffer的逻辑
return result;
```
7.3 取消自定义网络栈加载全部图片
```
如果用户执行了自定义网络加载全部图片,后面又不想自定义网络栈加载全部图片了,可以通过下面的方式恢复
ImageKnifeGlobal.getInstance().getImageKnife()?.replaceDataFetch(new CustomDataFetchClient());
```
### 8.监听图片加载成功与失败
#### 5.监听网络下载进度
```
ImageKnifeNextComponent({
imageKnifeNextOption: {
loadSrc: 'http://e.hiphotos.baidu.com/image/pic/item/4e4a20a4462309f7e41f5cfe760e0cf3d6cad6ee.jpg',
onLoadListener: {
console.log('Load Successful: ' + data);
return data;
},
onLoadFailed: (err) => {
console.error('Load Failed Reason: ' + err);
}
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)
```
## 进阶使用
#### 6.支持option传入border设置边框圆角
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。
```
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({
{
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
```
其他变换相关属性,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.pngSample"),
placeholderSrc:$r("app.media.loading")
},syncLoad:true
})
```
#### 10.ImageKnifeAnimatorComponent 示例
```

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%')
## 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"
}
}
```
`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PixelMapgif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
```
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
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 |
| -------- | -------- | -------- |-------------------------|

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) {

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。
