请教，MFC工程 调用DLL，传递IplImage、Mat、CImage参数，怎么传递！！！
现在的编写方式为
MFC工程调用代码：
Mat mat2 = imread("d://barcode.bmp");
//ATL::CImage cImage;
HINSTANCE hDll;
hDll = LoadLibrary(TEXT("FireMeasureCOM.dll"));
typedef char*(*handleFun)(Mat);
handleFun funHandle;
if(hDll!=NULL)
{
funHandle = (handleFun)GetProcAddress(hDll,"Handle");
if(funHandle!=NULL)
{
string str="";
str = funHandle(mat2);
}
}
DLL接受函数的代码：
AOICOMDLL string Handle(Mat image)
{
//CImage cImage;
//MatToCImage(image,cImage);
//CvMat stub = (CvMat)image;
IplImage sourceImage = image;
MeasureBusiness business = MeasureBusiness(&sourceImage);
map<string,map<double,int>> temp = business.Handle();
string returnStr = ConvertMapToStr(temp);
return returnStr;
}
问题是：
DLL接受函数收到的参数image提示“指针错误”，不能转换为IplImage。
求大牛帮忙解答。 MFC C++ Mat Dll IplImage
[解决办法]
DLL接受函数的代码：
AOICOMDLL char* Handle(Mat& image)
{
//CImage cImage;
//MatToCImage(image,cImage);
//CvMat stub = (CvMat)image;
IplImage sourceImage = image;
MeasureBusiness business = MeasureBusiness(&sourceImage);
map<string,map<double,int>> temp = business.Handle();
string returnStr = ConvertMapToStr(temp);
return returnStr;
}
或者：
DLL接受函数的代码：
AOICOMDLL char* Handle(Mat* image)
{
//CImage cImage;
//MatToCImage(image,cImage);
//CvMat stub = (CvMat)image;
IplImage sourceImage = *image;
MeasureBusiness business = MeasureBusiness(&sourceImage);
map<string,map<double,int>> temp = business.Handle();
string returnStr = ConvertMapToStr(temp);
return returnStr;
}
试试吧
是在用GDI+ 吗？？？
[解决办法]
嗯，这都是OpenCV的基础知识啊。。。前两者有派生关系啊，CImage是需要转化的。是GDI+的那个CImage吧？
