提问by sarmad m
I want to get image width and height, how can I do that in OpenCV?
我想获得图像的宽度和高度，我该如何在 OpenCV 中做到这一点？
For example:
例如：
Mat src = imread("path_to_image");
cout << src.width;
Is that right?
那正确吗？

You can use rowsand cols:
您可以使用rows和cols：
cout << "Width : " << src.cols << endl;
cout << "Height: " << src.rows << endl;
or size():
或size()：
cout << "Width : " << src.size().width << endl;
cout << "Height: " << src.size().height << endl;

Also for openCV in python you can do:
同样对于python中的openCV，您可以执行以下操作：
img = cv2.imread('myImage.jpg')
height, width, channels = img.shape
