如何将字符串转换为PIL Image对象,我正在考虑使用frombytes()函数和PIL中的Image模块.
PILImage.open
可以接受字符串(表示文件名)或类似文件的对象,并且io.BytesIO
可以充当类文件对象:
import base64
import io
from PIL import Image
def img_to_txt(filename):
msg = b"<plain_txt_msg:img>"
with open(filename, "rb") as imageFile:
msg = msg + base64.b64encode(imageFile.read())
msg = msg + b"<!plain_txt_msg>"
return msg
def decode_img(msg):
msg = msg[msg.find(b"<plain_txt_msg:img>")+len(b"<plain_txt_msg:img>"):
msg.find(b"<!plain_txt_msg>")]
msg = base64.b64decode(msg)
buf = io.BytesIO(msg)
img = Image.open(buf)
return img
filename = 'test.png'
msg = img_to_txt(filename)
img = decode_img(msg)
img.show()
