MFC多文档中opencv处理图像打开、保存

需要在C**Doc和C**View中进行相应修改

图像打开：

Doc.cpp中：

[cpp] view plain copy

BOOL CCVMFCDoc::Load(IplImage** pp, LPCTSTR csFilename)

{

IplImage* pImg=NULL;

pImg = cvLoadImage(csFilename,-1); // 读图像文件(DSCV)

if (!pImg) return(false);

cvFlip(pImg); // 与 DIB 像素结构一致

if (*pp) {

cvReleaseImage(pp);

}

(*pp)=pImg;

m_Display=0;

return(true);

}

[cpp] view plain copy

BOOL CCVMFCDoc::OnOpenDocument(LPCTSTR lpszPathName)

{

if(!CDocument::OnOpenDocument(lpszPathName)) return false;

Load(&pImg,lpszPathName);

if(pImg) return true;

return false;

}

图像保存：

1.Doc.cpp中

[cpp] view plain copy

BOOL CCVMFCDoc::Save(LPCTSTR csFilename, IplImage* pImg)

{

int bl;

cvFlip(pImg); // 恢复原 OpenCV 位图结构

bl=cvSaveImage(csFilename,pImg); // 图像存盘

return(bl);

}

2.View.cpp中

[cpp] view plain copy

void CCVMFCView::OnFileSaveAs()//图像保存

{

CFileDialog dlg(false,"*.bmp","Test.bmp",OFN_HIDEREADONLY |OFN_OVERWRITEPROMPT,"保存为(*.bmp)|*.bmp|所有文件(*.*)|*.*||");

CString strPath("");

if(dlg.DoModal()==IDOK)

{

cvFlip(workImg);

strPath=dlg.GetPathName();

cvSaveImage(strPath,workImg);

cvFlip(workImg);

}

}

整体代码如下：
