如何使用python正确编码和解码base64图像以获得完全相同的图像？

Question

手术期间我遗漏了一些东西，因为图像不一样（尽管在视觉上看不到差异）。

MWE：

import base64
from io import BytesIO

from PIL import Image

image = Image.open('image.jpg')
buffered = BytesIO()
image.save(buffered, format="JPEG")
image_content = base64.urlsafe_b64encode(buffered.getvalue())

image_decoded = Image.open(BytesIO(base64.urlsafe_b64decode(image_content.decode())))

print(image == image_decoded)
# return False
print(np.array(image).sum() == np.array(image_decoded).sum())
# return False

Answer 1

我终于通过@Idlehands评论将其整理出来。 Image.open(...)已更改二进制内容。

一个可行的解决方案：

import base64

from PIL import Image

with open('image_name.jpg', 'rb') as image_file:
    image_byte = image_file.read()
    image_base64 = base64.urlsafe_b64encode(image_byte)

with open('test.jpg', 'wb') as image_file:
    image_file.write(base64.urlsafe_b64decode(image_base64))


image = Image.open('image_name.jpg')
image_decoded = Image.open('test.jpg')
image == image_decoded
