python 获取图片分辨率的方法

pil版：

from PIL import Image

filename = r'E:datayangben.jpg'
img = Image.open(filename)
imgSize = img.size #图片的长和宽
print (imgSize)
maxSize = max(imgSize) #图片的长边

minSize = min(imgSize) #图片的短边
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))
