//首先安装openCV1.0

//配置目录

//配置项目属性，LINK标签要加入cxcore.lib cv.lib ml.lib cvaux.lib highgui.lib cvcam.lib

//简单显示一幅图的源码

#include "cv.h"#include "highgui.h"int main(int argc, char* argv[]){ IplImage* pImg; pImg = cvLoadImage("D://img//y8.jpg", 1); // 注意是双斜杠 cvNamedWindow("Image", 1); cvShowImage("Image", pImg); cvWaitKey(0); cvDestroyWindow("Image"); cvReleaseImage(&pImg); return 0;}//将image贴到ID所在区域的通用代码void CCaptureImageDlg::DrawPicToHDC(IplImage* image, UINT ID){/* CDC* pDC = GetDlgItem(ID)->GetDC(); HDC hDC = pDC->GetSafeHdc(); CRect rect; GetDlgItem(ID)->GetClientRect(&rect); CvvImage cimg; cimg.CopyOf(image); cimg.DrawToHDC(hDC,&rect); ReleaseDC(pDC);*/CDC* pDC = GetDlgItem(ID)->GetDC(); HDC hDC = pDC->GetSafeHdc();CRect rect;GetDlgItem(ID)->GetClientRect(&rect);int rw = rect.right - rect.left;int rh = rect.bottom - rect.top;int iw = image->width;int ih = image->height;int tx = (rw - iw) / 2;int ty = (rh - ih) / 2;SetRect(rect, tx, ty, tx + iw, ty + ih);CvvImage cimg;cimg.CopyOf(image);cimg.DrawToHDC(hDC,&rect); ReleaseDC(pDC);}
