如何在Python中将save_base64转换为图像 [英] How to Convert save_base64 to Image in Python

问题描述

我使用以下代码下载带有查询字符串的图像，这没有任何问题.

I use code as below to download Image with query string, it is no any problems.

urlServer = "http://ipcamera-viewer.com/image/?p=199619_20170221_162149_7208.jpg"
browser.get(urlServer)
imgData = browser.get_screenshot_as_base64()
size = int(len(imgData) * 0.75)
if size > minSizeImage:
    browser.save_screenshot(pathLocal)

现在我想旋转图像，然后再保存到文件中，我可以使用代码

now I want to rotate the image before save to file, can I use code

urlServer = "http://ipcamera-viewer.com/image/?p=199619_20170221_162149_7208.jpg"
browser.get(urlServer)
imgBase64= browser.get_screenshot_as_base64()
imgBytes = BytesIO(base64.b64decode(imgBase64))
imgData = PIL.Image.open(imgBytes)
size = int(len(imgBase64) / 8)
if size > minSizeImage:
    imgData = imgData.rotate(angle, expand = True)
    imgData.save(pathLocal)

推荐答案

这种方法应该可以解决问题，而不是保存以便再次阅读.没机会尝试一下.

Something like this should do the trick, rather then saving just to read it in again. Didn't get the chance to try this out though.

from PIL import Image
from io import BytesIO
import base64


im = Image.open(BytesIO(base64.b64decode(imgData)))
im = im.rotate(45)
im.save(pathLocal)
