import cv2
path = "D:/picture/source_image.png"
img = cv2.imread(path)
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))
更改:
from PIL import Image
import os.path
import glob
def convertjpg(jpgfile,outdir,width=1280,height=720):
img=Image.open(jpgfile)
try:
new_img=img.resize((width,height),Image.BILINEAR)
new_img.save(os.path.join(outdir,os.path.basename(jpgfile)))
except Exception as e:
print(e)
for jpgfile in glob.glob("D:/picture/source_image.png"):
convertjpg(jpgfile,"D:/picture/")
