2.2.5 C#中显示控件BDPictureBox 的实现----ROI交互续2

1 ROI数组作用说明

变量：m_ROIs[5]
ROI 使用效果图

ROI数组说明
ROIs数组图片

2 ROI显示逻辑图

ROI 交互主要是在设定状态下， runmode下只要普通显示即可
ROI显示逻辑

3 主要ROI显示函数函数

判断当前鼠标是否获取KeyPoint
鼠标move时，拖放ROI的姿态和大小
显示更新ROI

3.1 get_interactive_key_draw_point

获取当前ROI 关键点选中信息

/// <param name="y"></param>
/// <returns></returns>

}

3.2 drag_interactive_ROI

拖放当前ROI ，并且更新ROI

}

3.3 显示更新ROI
