如何用c/c ++最容易处理jpg图像？

#include <opencv2/core.hpp>
#include <opencv2/highgui.hpp>
#include <opencv2/imgproc.hpp>

#include <opencv2/core.hpp>
#include <opencv2/highgui.hpp>
#include <opencv2/imgproc.hpp>

int main(int argc, char** argv) {
    cv::Mat image = cv::imread("example.jpg", cv::IMREAD_COLOR);
    if (!image.data) {
        std::cout << "No image data"<< std::endl;
        return -1;
    }
    cv::imshow("Display Window", image);
    cv::waitKey(0);
    return 0;
}

    }
    // Process image
    // ...
    // Save processed image to file
    cv::imwrite("output.jpg", image);
    // Compress image to JPG format
    std::vector<int> compression_params;
    compression_params.push_back(cv::IMWRITE_JPEG_QUALITY);
    compression_params.push_back(95);
    cv::imencode(".jpg", image, compressed_image, compression_params);
    return 0;
}
