易采站长站为您分析C#实现控制摄像头的类,涉及C#操作摄像头的初始化、抓图、录像等功能,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了C#实现控制摄像头的类。。具体如下:
- /// <summary> /// 一个控制摄像头的类
- /// </summary> public class Pick
- { private const int WM_USER = 0x400;
- private const int WS_CHILD = 0x40000000; private const int WS_VISIBLE = 0x10000000;
- private const int WM_CAP_START = WM_USER; private const int WM_CAP_STOP = WM_CAP_START + 68;
- private const int WM_CAP_DRIVER_CONNECT = WM_CAP_START + 10; private const int WM_CAP_DRIVER_DISCONNECT = WM_CAP_START + 11;
- private const int WM_CAP_SAVEDIB = WM_CAP_START + 25; private const int WM_CAP_GRAB_FRAME = WM_CAP_START + 60;
- private const int WM_CAP_SEQUENCE = WM_CAP_START + 62; private const int WM_CAP_FILE_SET_CAPTURE_FILEA = WM_CAP_START + 20;
- private const int WM_CAP_SEQUENCE_NOFILE = WM_CAP_START + 63; private const int WM_CAP_SET_OVERLAY = WM_CAP_START + 51;
- private const int WM_CAP_SET_PREVIEW = WM_CAP_START + 50; private const int WM_CAP_SET_CALLBACK_VIDEOSTREAM = WM_CAP_START + 6;
- private const int WM_CAP_SET_CALLBACK_ERROR = WM_CAP_START + 2; private const int WM_CAP_SET_CALLBACK_STATUSA = WM_CAP_START + 3;
- private const int WM_CAP_SET_CALLBACK_FRAME = WM_CAP_START + 5; private const int WM_CAP_SET_SCALE = WM_CAP_START + 53;
- private const int WM_CAP_SET_PREVIEWRATE = WM_CAP_START + 52; private IntPtr hWndC;
- private bool bStat = false; private IntPtr mControlPtr;
- private int mWidth; private int mHeight;
- private int mLeft; private int mTop;
