Help with a python script for nautilus

[Major_Kong]

I'm trying to make a python script that adds a new column for nautilus (a image size column). A new column is added, but it doesn't seem to work...

Problems: I am unable to add just one column, so i made a 'dummy' column, date.
And i can't seem to get the size of the image...

The code:


#!/usr/bin/python

# this script can installed to the user account by running the following commands:

# sudo apt-get install python-nautilus
# mkdir ~/.nautilus/python-extensions
# cp dimc.py ~/.nautilus/python-extensions
# chmod a+x ~/.nautilus/python-extensions/dimc.py


import nautilus
import urllib
# for extracting the image size
import Image

class ColumnExtension(nautilus.ColumnProvider, nautilus.InfoProvider):
def __init__(self):
pass

def get_columns(self):
return (
nautilus.Column("NautilusPython::img_dimensions_column",
"img_dimensions",
"Dimensions",
"Image dimensions"),
nautilus.Column("NautilusPython::date_column",
"date",
"Date",
"Date")
)

def update_file_info(self, file):
if file.get_uri_scheme() != 'file':
return

if file.is_mime_type('image/jpeg') or file.is_mime_type('image/png') or file.is_mime_type('image/gif'):
filename = urllib.unquote(file.get_uri()[7:])
im = Image.open(filename)
file.add_string_attribute('dimensions', str(im.size[0]) + " x " + str(im.size[1]) )
else:
file.add_string_attribute('dimensions', '')

file.add_string_attribute('date', '')
self.get_columns()

Help please ?

Found out the problem for myself:


#!/usr/bin/python

# this script can installed to the user account by running the following commands:

# sudo apt-get install python-nautilus
# mkdir ~/.nautilus/python-extensions
# cp imgsc.py ~/.nautilus/python-extensions
# chmod a+x ~/.nautilus/python-extensions/imgsc.py


import nautilus
import urllib
# for extracting the image size
import Image

class ColumnExtension(nautilus.ColumnProvider, nautilus.InfoProvider):
def __init__(self):
pass

def get_columns(self):
return (nautilus.Column("NautilusPython::img_size_column",
"img_size",
"Image Size",
"Image Size"),
nautilus.Column("NautilusPython::img_width_column",
"img_width",
"Width",
"Image Width"),
nautilus.Column("NautilusPython::img_height_column",
"img_height",
"Height",
"Image height")
)

def update_file_info(self, file):
if file.get_uri_scheme() != 'file':
return

if file.is_mime_type('image/jpeg') or file.is_mime_type('image/png') or file.is_mime_type('image/gif'):
filename = urllib.unquote(file.get_uri()[7:])
im = Image.open(filename)
file.add_string_attribute('img_size', str(im.size[0]) + ' x ' + str(im.size[1]) )
file.add_string_attribute('img_width', str(im.size[0]))
file.add_string_attribute('img_height', str(im.size[1]))
else:
file.add_string_attribute('img_size', '')
file.add_string_attribute('img_width', '')
file.add_string_attribute('img_height', '')


self.get_columns()


Didn't find a solution for adding just one column, but i guess it's not that important.
