This will create thumbnails for word files but you need Abiword installed

SCHWEET! Works great - any chance this can be incorporated into dapper with an option to turn it off sumwhere?

Probably yes: I filed this bug: http://bugzilla.ubuntu.com/show_bug.cgi?id=19715 and almost immediately got a positive respons on it from Sebastien Bacher...

How would you go about extending this to include html and other online documents? Works great at the moment though, don't get me wrong, just that I had a bit of an idea for a different take on bookmarks, which would need this!

Is this still a planned feature?

yay is working

Can anyone give me a pointer on how to create a schema for something other than an oasis-document file?

I want to create thumbnails in nautilus for .cbr / .cbz files based on the first image in the files. (.cbr files are just in RAR format, while .cbz files are in ZIP format) The archives will just be a collection of .jpg image files.

It's simple first you need mime type for your files. All mime types are stored under /usr/share/mime. For cbz it is "application/x-cbz" for cbr it's "application/x-cbr" (if you don't believe me look in /usr/share/mime/application ) but in schema you will use it as "application@x-cbz" and "application@x-cbr"

For schema itself look into /usr/share/gconf/totem-video-thumbnail.schemas and evince-thumbnailer.schemas in the same directory. You will get an idea.

I don't know what for the "%s" is but "%u" is URL of thumbnailed file and "%o" is URL of png image which will be used as thumbnail. So to make thumbnail you basicaly need to crate a png from %u file and copy it to %o . In your case extract the jpg image, convert it to png and save it as %o.

Notice that "%u" URL you will get in form "file:///pathtofile" so you need to strip first 7 letters of this URL before it's useable.

I hope this helped you

%s is the max image size

Thanks a lot, guys. Also, thanks go out to the folks at comp.lang.python, who helped me write the python code that follows.

Here is the code to create thumbnails for .cbz sequential image archives (usually associated with comical or comix in linux or cdisplay on MSWindows).

sudo gedit /usr/bin/comical-thumbnailer

#!/usr/bin/python

import zipfile
import sys
import gnomevfs
import Image
import StringIO

inURL=gnomevfs.get_local_path_from_uri(sys.argv[1])
outURL=sys.argv[2]

zip=zipfile.ZipFile(inURL,mode="r")
jpeglist=[x for x in zip.namelist() if '.jp' in x]
try:
  picture=zip.read(jpeglist[0])
except IndexError:
  print 'No jpeg found'

zip.close() #close the file, since we no longer have need of it
image = Image.open(StringIO.StringIO(picture)) # create image object from file-like object
image.thumbnail((128,128),Image.ANTIALIAS) #create the thumbnail
image.save (outURL, "PNG") #output the file in the proper format

sudo chmod a+rx /usr/bin/comical-thumbnailer

sudo gedit /usr/share/gconf/schemas/comical.schemas
