将jpeg字符串转换为PIL图像对象 [英] Converting jpeg string to PIL image object

问题描述

我从应用程序的后端收到了应该是jpeg文件的文件列表.但是对于我一生，我一直无法将它们转换为PIL图像对象.当我打电话

I've been handed a list of files from the backend of an application that are supposed to be jpeg files. However for the life of me I haven't been able to convert them into PIL image objects. When I call

str(curimg)

我回来了:

<type 'str'>

.我试过使用open()、. read，io.BytesIO(img.read()，但也没有做任何事情，但始终将其视为字符串.当我打印字符串时，我得到了无法识别的字符.有人知道吗如何告诉python如何将该字符串解释为jpeg并将其转换为药丸图像，我可以在其中调用.size和np.array?

. I have tried using open(), .read, io.BytesIO(img.read() and also doing nothing to it, but it keeps seeing it as a string. When i print the string, I get unrecognizable characters. Does anyone know how to tell python how to intepret this string as a jpeg and convert it into a pill image where I can call .size and np.array on?

推荐答案

您应该能够将StringIO对象传递给PIL并以这种方式打开它.

You should be able to pass a StringIO object to PIL and open it that way.

即:

from PIL import Image
import StringIO
tempBuff = StringIO.StringIO()
tempBuff.write(curimg)
tempBuff.seek(0) #need to jump back to the beginning before handing it off to PIL
Image.open(tempBuff)
