## Getting Started

#####
Solution 1: Remote warehouse import project
```
implementation ‘com.gitee.baijuncheng-open-source:compresshelper:1.0.0’
```

Solution 2：Add compresshelper to your project

1.Copy the compresshelper/entry folder to the project directory

2.Modify settings.gradle under the project and add the dependency on this module as follows:
```
include ':entry', ':compresshelper'
```

3. Introduce the dependency of the module under the project. Taking the entry module as an example, you need to modify the build.gradle file under the entry module to add the dependency:
```
implementation project(':compresshelper')
```

Solution 3: local use of har package integration
1. Compile this project, copy the har package generated in the build directory of the compresshelper/entry folder to the project lib folder:
directory：\CompressHelper_master\compresshelper\build\outputs\har\debug\compresshelper-debug.har
2. Add the following code in the entry's gradle
```
implementation fileTree(dir:'libs', include: ['*.jar','*.har'])
```

​	More configuration can be found in the Project.Usage

- Used within Ability:

```java
newFile = CompressHelper.getDefault(getApplicationContext()).compressToFile(oldFile);
```
- You can also customize compression

```java
newFile = new CompressHelper.Builder(this)
       .setMaxWidth(720)  // 默认最大宽度为720
        .setMaxHeight(960) // 默认最大高度为960
        .setQuality(80)    // 默认压缩质量为80
        .setCompressFormat(ImageFormat.ComponentType.JPEG) // 设置默认压缩为jpg格式
        .setFileName(yourFileName) // 设置你的文件名
        .setDestinationDirectoryPath(
                Environment.DIRECTORY_PICTURES)
        .build()
        .compressToFile(oldFile);
```
