pil版：

from PIL import Image

filename = r'E:\data\yangben\0.jpg'
img = Image.open(filename)
imgSize = img.size #圖片的長和寬
print (imgSize)
maxSize = max(imgSize) #圖片的長邊

minSize = min(imgSize) #圖片的短邊
print(maxSize, minSize)

opencv版

img = cv2.imread(F1)

sp = img.shape
height = sp[0]  # height(rows) of image
width = sp[1]  # width(colums) of image
chanael = sp[2]  # the pixels value is made up of three primary colors
print ( 'width: %d \nheight: %d \nnumber: %d' % (width, height, chanael))
