    Re: HOWTO: Thumbnails for OpenOffice.org 2 files

    Hi,
    I just install this new version of ooo-thumbnailer. Thanks a lot, it's almost perfect to me. I have some office files that are not thumbnailed, but in general it's quite better than libgsf-bin.
    Since you seems to be an advanced user concerning thumbnail, I have a question. Since my passage to Lucid, my ppt files are greyed and really hideous. (Screenshot)
    It's not related to your script, they appear like this since my re-installation, even if I cleared .thumbnails.
    Thanks, if someone could help me...
    Mel

    Hmm, that does look awful. I'm suspecting a bug in libgsf-bin. Try:
    Code:
    gsf-office-thumbnailer -i powerpoint.ppt -o out.png -s 128
    And look at out.png.

    Thanks to you for interest in my problem.
    I tried with 2 different ppt
    One giving a grey thumbnail:

    Code:
    melanie@melanie-portable:/$ gsf-office-thumbnailer -i ~/Aires10jc_Tremblay_2010-02-16_VPA\ urea\ cycle.ppt -o ~/out.png -s 128
    
    (gsf-office-thumbnailer:3037): GdkPixbuf-CRITICAL **: at_scale_size_prepared_cb: assertion `width > 0 && height > 0' failed
    
    (gsf-office-thumbnailer:3037): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed
    One giving a OK thumbnail:
    Code:
    melanie@melanie-portable:/$ gsf-office-thumbnailer -i ~/Brown10jc_Tremblay_2010-04-29_3CPD\ colliculus.ppt -o ~/out.png -s 128
    calling convert '/home/melanie/out.png.GAB6CV' +matte -thumbnail 128x128 png:'/home/melanie/out.png'
    
    (gsf-office-thumbnailer:4801): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed
    I already tried a re-install of libgsf-bin, in case you ask. I could also add a precision : on my netbook (running also Lucid), I don't have this problem (with the same powerpoint files).
    Thanks,
    Mel

    Well, it looks like a bug in libgsf-bin I'm afraid, and I don't know what's causing it.

    You might want to try reinstalling imagemagick as the second command calls convert while the first one doesn't for some reason.

    Another idea is to uninstall imagemagick completely, libgsf-bin doesn't depend on it, it only suggests it. ooo-thumbnailer does depend on imagemigick, but it might help pinpoint the source of the problem.

    Thanks.
    Unfortunately it doesn't work. I'm still looking for a solution if someone found it...

    now ooo-thumbnailer does not work any more
