无法使用python PIL Image.show显示图像 [英] Unable to show an image using python PIL Image.show

问题描述

我正在使用Python Imaging Library，但无法在Windows Live Photo Gallery中成功打开图像.出现一条消息，提示没有选择照片或视频"，而不是图像.

I'm using the Python Imaging Library and I am unable to open an image successfully in Windows Live Photo Gallery. There is a message that shows up saying "There are no photos or videos selected" instead of the image.

这是我尝试过的:

import Image

img = Image.open(r"C:\Users\User\Pictures\image.jpg")
img.show()

这与PIL手册教程中的内容几乎相同，所以我不确定哪里出了问题.

This is pretty much the same as in the PIL handbook tutorial, so I'm not sure where I'm going wrong.

推荐答案

文档说:

在Windows上，它[show()]将图像保存到一个临时的BMP文件中，并使用标准的BMP显示实用程序来显示它.

On Windows, it [show()] saves the image to a temporary BMP file, and uses the standard BMP display utility to show it.

问题是您的程序以某种方式立即退出，该临时文件在退出时被删除，Windows等找不到该文件.作为临时解决方案，请尝试添加:

Problem is that your program exits immediately somehow, the temporary file is deleted upon exit and Windows etc. cannot find it. As a temporary solution, try adding:

import time
# Your code as above
time.sleep(30)

这将使程序在退出之前等待30秒.如果愿意，可以让它等待用户按下键.

This will make the program wait 30 seconds before exiting. If you prefer, you could make it wait the user to press a key.

看来您遇到临时文件问题.解决方法是，使用img.save("C:\Users\User\Pictures\test.jpg")将图像保存在磁盘上的某个位置，然后使用您喜欢的图像查看器将其打开.每当您要显示经过处理的图像时，请再次调用save，然后将图像重新加载到图像查看器中.

it seems like you are experiencing problems with temporary files. As a workaround, save the image somewhere on the disk using, say, img.save("C:\Users\User\Pictures\test.jpg") and open it with your favorite image viewer. Whenever you want to show the processed image, call save again and reload the picture in the image viewer.
