Method for Checking Image Integrity Based on Pillow in Python

This article describes a method for determining the integrity of images based on pillow in Python. Shared for everyone's reference, as follows:

1Install third-party libraries.

pip install pillow

2Function examples.

# encoding=utf-8
# author: walker
# date: 2016-07-26
# summary: Determine the validity of the image
import io
from PIL import Image
# Determine if the file is a valid (complete) image
# Input parameter is the file path
def IsValidImage(pathfile):
  bValid = True
  try:
    Image.open(pathfile).verify()
  except:
    bValid = False
  return bValid
# Determine if the file is a valid (complete) image
# Input parameter is bytes, such as binary data returned by network requests
def IsValidImage4Bytes(buf):
  bValid = True
  try:
    Image.open(io.BytesIO(buf)).verify()
  except:
    bValid = False
  return bValid
