作者:郑海波 2012-08-12 Email:zhb931706659@126.com
1.布局
有TextView、ImageView和Button三种控件
2.功能:
2.1 显示:系统初始化时,显示Lenna图像
2.2 打开图像:Open按钮完成打开图像功能。点击Open按钮,用户可以选择媒体库中的图像;
2.3 处理图像:Process按钮。当点击时,跳转到一个算法选择的Activity,根据用户的选择,系统开始处理图像;
2.4 保存图像:Save按钮。将当前显示的图像保存到原图像的路径,即替换原图像。
2.5 拍照功能:Camera按钮。用户可以打开摄像头,将拍照的图像作为素材。
2.6 截图功能:Screen按钮。点击按钮,将当前用户的界面截取下来,作为拍照的素材。
2.7 触摸功能:在ImageView区域触摸,当用户点击图像时,图像由‘原大小’变为‘适合屏幕’或相反。向上滑动,显示系统的lenna图像。向右滑动,显示上一幅图像。向下滑动,显示原图像。
