Python PIL problem

[cisforcojo]

I am using the PIL and have this code (very simple):

import Image
pic = Image.open('image.jpg')

pic.show()

runs 'fine' but show() does nothing. Perhaps I am doing something wrong but in the tutorial it says that this should display the file?

I just tried something similar. When I try to use the show() function, I get the error "sh: xv: command not found".

This tutorial, after mentioning the show() functon, says

(The standard version of show is not very efficient, since it saves the image to a temporary file and calls the xv utility to display the image. If you don't have xv installed, it won't even work. When it does work though, it is very handy for debugging and tests.)

The program xv is not installed in dapper, and I couldn't find a package for it. I do have imagemagick installed, which provides the display command, so as a hack, I made a symlink:

sudo ln -s /usr/bin/display /usr/local/bin/xv

Now running xv actually runs display, and the show() function works.

I have /usr/local/bin in my PATH. If you don't, and you don't want to bother setting it up, you could make the symlink in /usr/bin:

sudo ln -s /usr/bin/display /usr/bin/xv

I just did as you suggested but no dice. I also have imagemagick installed and do have /usr/bin/display but I get the exact same turnout as before (nothing). The program just runs and finishes and doesn't display anything.
That 'xv' bit is interesting though. I also don't have it installed nor is there a .deb for it.

Bumping to say it worked for me!

Thnx a lot!

pic.show() works.
and something else. what about closing
how can we close that window with python?

thanks.

I tried something similar with xloadimage which can be installed using the Synaptic package manager or apt-get. After installing, I applied the following symbolic link.

sudo ln -s /usr/bin/xloadimage /usr/bin/xv

Then you can display an image by xv <image filename>. However, xloadimage dumps a lot of status to stdout, so I use ImageMagick display like WW suggested above.

I use Eye of Gnome which is installed by default.

sudo ln -s /usr/bin/eog /usr/bin/xv

I saw the following information posted by Emrahustun. I am wondering if anybody has realized this function closing this picture with python after showing a picture. My current research needs to realize this function. Please give me some advice. I will very appreciate it.

@WW: There's an XV package for openSuSE - so I'd be surprised if there's nothing for Ubuntu - but it's a very old app, nevertheless

@angelachen:
what about brute force killing the image with popen:
os.popen('killall display') or os.popen('killall xv'), probably combined with a sleep or wait statement before that?

sudo ln -s /usr/bin/eog /usr/bin/xv

Worked for me!
Thanks.
