 **手写板 & 高拍仪 App 演示Gap** ：

1、高拍仪主页：自由框选、智能拼接、拍摄效果、保存格式 均未实现；

2、高拍仪图片编辑页：画框保留、画框补齐、图像补齐、去噪、去黑边、 放大、缩小、最大化 . . . . . . . .. .全部未实现；

3、WGR转测版本无法使用高拍仪，需要推OH Camera的包才能使用；

4、手写板 笔设置界面 “笔”图片格式有问题，不是透明格式；

5、手写板 笔设置界面 笔记效果体验区 未实现；

6、手写板 笔设置界面 清除笔记按钮 未实现；

7、手写板 区域设置界面 上下旋转、左右旋转 功能未实现；

8、手写板 区域设置界面 区域设置、自动矫正、默认全屏映射 功能未实现；
