python中图片转为base编码

====

Python中将图片转base

# import base
with open("/home/chaowei/1.png", "rb") as fs:
    # bencode：编码，bdecode: 解码
    base_data = base.bencode(f.read())
    # base.bdecode(base_data)
    print(base_data)

Python中将base转为opencv的Mat格式

import cv2
import base
imgData = base.bdecode(base_data)
nparr = np.fromstring(imgData, np.uint8)
img_np = cv2.imdecode(nparr, cv2.IMREAD_COLOR)
#cv2.imshow("test",img_np)
#cv2.waitKey(0)
