This is my command

'''
data[0] = getData(CMD_PHOTO1, req)
'''
'''
print(data[0])
'''

#I try to read this again but stuck
data[0] = getData(CMD_PHOTO1, req)
print(data[0])
print("P1")
data[1] = data[0]+ getData(CMD_PHOTO2, req)
print(data[1])
print("P2")
s = data[1]
i = np.frombuffer(s,dtype=np.uint8)
im = cv2.imdecode(i,cv2.IMREAD_UNCHANGED)
cv2.imwrite('result.png',im)

  • The first two bytes are `ff`, `d8` in hex which is a JPEG marker. So you have a JPEG-encoded image. You can either save the bytes to a file with `.jpg` extension, or wrap it in a `io.BytesIO` and use PIL's `Image.open(io.BytesIO(yourThing))` – Mark Setchell Jun 19 '20 at 18:30
  • Or you can use OpenCV `imdecode()` like here... https://stackoverflow.com/a/62364915/2836621 – Mark Setchell Jun 19 '20 at 18:34
  • ###I try to read from smartcard image please help I am newbie – pjclient client Jun 20 '20 at 01:12
  • Your device seems to be giving you a list, or even a list of lists. Your list starts correctly for a JPEG with hex `ff`, `d8` (255, 216) but you don't seem to have the entire list because it should end with `ff`, `d9` (255, 217)`. I am not familiar with your device, but when you recover that list, my linked answer should work. – Mark Setchell Jun 20 '20 at 07:21
