#includeThis code uses the OpenCV library to read an image file and get its width in pixels. It uses the cols member of the cv::Mat class to get the image width. Package library: OpenCV.#include int main() { cv::Mat image = cv::imread("image.jpg"); // read image file int width = image.cols; // get image width in pixels std::cout << "Image width: " << width << std::endl; return 0; }
