摄像头组件调用示例

Snapshot526控件授权后抓拍到的图片以时间为基准自动命令，未授权再无法抓拍图片。保存的图片格式为bmp格式。包含包“Snapshot526.h”并在stdafx.h中或调用的模块中加入#pragma comment(lib, "Camera526.lib")然后在操作开始摄像头抓拍操作事件中CSnapshot526 snapshot; CString strFileName=L"",strFilePath; snapshot.SetGrantUserName(L"用户名"); //设置授权用户snapshot.SetGrantUserKey(L"授权号"); //设置授权号snapshot.SetCameraWindowSize(520,460); //设置视频窗口大小snapshot.SetSaveImagePath(L"debug"); //设置抓拍图片保存路径if(snapshot.ShowCameraDlg()) { strFileName = snapshot.GetPhotoFileName(); //获取抓拍图片文件名SetDlgItemText(IDC_STNAME,strFileName); strFilePath = snapshot.GetPhotoFilePath(); //获取图片路径if(!strFilePath.IsEmpty()) { //显示抓拍到的图片HDC hSrcDC; HDC hDesDC; HBITMAP hBitmap; BITMAP bm; CRect rect; Sleep(100); hDesDC = m_stPicture.GetDC()->m_hDC; hSrcDC = CreateCompatibleDC(hDesDC); hBitmap=(HBITMAP)LoadImage(AfxGetInstanceHandle(), strFilePath, IMAGE_BITMAP, 0, LR_LOADFROMFILE|LR_CREATEDIBSECTION); //m_stPicture.SetBitmap(hBitmap); GetObject(hBitmap, sizeof(BITMAP), &bm); SelectObject(hSrcDC, hBitmap); m_stPicture.GetClientRect(&rect); ::SetStretchBltMode(hDesDC, COLORONCOLOR); ::StretchBlt(hDesDC, rect.left, rect.top, rect.right, rect.bottom, hSrcDC, 0, bm.bmWidth, bm.bmHeight,+SRCCOPY); m_stPicture.InvalidateRect(rect); } }注意，需要把文件Snapshot526.h拷到工程中并加入，另需要Camera526.dll和Camera526.lib文件。具体查看示例
