###  安装教程

方式一：

1. 下载E-signature的模块代码添加到自己的工程

2. 关联使用

   ```
   dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar', '*.har'])
        implementation project(":handwrite")
        ...
    }
   ```

3. gradle sync

方式二：

```
allprojects {
    repositories {
        mavenCentral()        
    }
}

...
dependencies {
	...
	implementation 'com.gitee.archermind-ti:E-signature:1.0.0'
	...
}
```

### 使用说明

- 添加View

```xml
<DirectionalLayout
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    ohos:height="match_parent"
    ohos:width="match_parent"
    ohos:orientation="vertical"
    ohos:total_weight="1">


    <com.archermind.handwrite.view.HandWriteView
        ohos:id="$+id:handwriting"
        ohos:height="0px"
        ohos:width="match_parent"
        ohos:weight="0.99"
        ohos:background_element="#000000"
        />
	<!-- 按钮组件	 -->
</DirectionalLayout>
```

- 保存


```java
if (hwView.isSign())
                try {
                    if (isCrop) {
                        String path=getExternalFilesDir(Environment.DIRECTORY_PICTURES).getAbsolutePath()
                                + File.separator + "ls.jpeg";
                        //暂无法实现自定义GlideModule,故不实现加密
                        //hwView.save(path, true, 10, true,this);
                        hwView.save(path,true,10,false,this);
                        Intent intent1 = new Intent();
                        intent1.setParam("path",path);
                        getAbility().setResult(101,intent1);
                        getAbility().terminateAbility();
                    } else {
                        String path=getExternalFilesDir(Environment.DIRECTORY_PICTURES).getAbsolutePath()
                                + File.separator + "qm.jpeg";
                        hwView.save(path,this);
                        Intent intent2 = new Intent();
                        intent2.setParam("path",path);
                        getAbility().setResult(100, intent2);
                        getAbility().terminateAbility();
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                }
            else {
                ToastDialog toastDialog = new ToastDialog(this);
                toastDialog.setText("还没有签名！").setDuration(5000).show();
            }

```


- 清除

```java
hwView.clear();
```

- 修改背景、笔宽、颜色

```java
    //最小宽度、最大宽度
  hwView.setPaintWidth(5, 20);
  hwView.setPaintColor(Color.WHITE);
```

#### 遗留问题
openHarmony版本暂不提供Glide，无法实现自定义GlideModule

###  版本迭代

- v1.0.0
