CFileItemPtr fileItemPtr("example.jpg"); if (fileItemPtr.IsPicture()) { std::cout << "This is a picture file" << std::endl; } else { std::cout << "This is not a picture file" << std::endl; }
CFileItemPtr fileItemPtr("example.txt"); if (fileItemPtr.IsPicture()) { std::cout << "This is a picture file" << std::endl; } else { std::cout << "This is not a picture file" << std::endl; }In this example, the file item pointer is created for a file named "example.txt", which is not a picture file. So when we call the IsPicture function, it returns a value of false and we print out a message saying that it's not a picture file. Based on the function name and variable names used in the examples, it's difficult to determine the specific package or library that this code is using. It's possible that it's part of a custom library used by the developer who wrote the code, or it could be part of a larger commercial or open-source library.
