CodePudding user response:

CImage or GDI++?

CodePudding user response:

I use opencv, but in ShowPicture (int nID, IplImage * Image) in the second parameter display error C2061

CodePudding user response:

Didn't include OPENCV header files

CodePudding user response:

The corresponding class header files to include in the project

CodePudding user response:

Include links to the corresponding header file, the corresponding lib file

CodePudding user response:

Header files are included

CodePudding user response:

IplImage * iplimg;
* iplimg=IplImage (imageleft);

Pointer to the function name with the same name?

CodePudding user response:

Opencv several? CvvImage already cancelled?
