    HOWTO: Animated .gif as a background

    So you went to put that funny animated gif as your desktop background but only the first frame appeared, static and alone? Cheer up, we can make it move.
    This is a guide to getting an animated gif centered on your desktop background. I've only tested it in gnome on Hardy Heron. It works with or without compiz. The only caveat is that if you happen to have icons on your desktop the gif may cover these up if it's big enough.

    Alright let's open a terminal window and get down to business.
    We're going to grab Shantz modified (i.e. fixed) version of xwinwrap.
    Ok we need the source from launchpad, but first we need to install bazaar to get the code, gcc to compile it, and gifsicle to actually display the gifs:
    Code:
    sudo apt-get install bzr build-essential gifsicle
    Now let's grab the code:
    Code:
    bzr branch lp:xwinwrap
    Let's change into that newly created directory and compile it and then install it.
    Code:
    cd xwinwrap
    make
    sudo make install
    I've created a little script to make centering a gif easy for myself so open up your favorite text editor and copy and paste the following:
    Code:
    #!/bin/sh
    # Uses xwinwrap to display given animated .gif in the center of the screen
    
    if [ $# -ne 1 ]; then
        echo 1>&2 Usage: $0 image.gif
        exit 1
    fi
    
    #get screen resolution
    SCRH=`xrandr | awk '/current/ { print $8 }'`
    SCRW=`xrandr | awk '/current/ { print $10 }'`
    SCRW=${SCRW%\,}
    
    #get gif resolution
    IMGHW=`gifsicle --info $1 | awk '/logical/ { print $3 }'`
    IMGH=${IMGHW%x*}
    IMGW=${IMGHW#*x}
    
    #calculate position
    POSH=$((($SCRH/2)-($IMGH/2)))
    POSW=$((($SCRW/2)-($IMGW/2)))
    
    xwinwrap -g ${IMGHW}+${POSH}+${POSW} -ov -ni -s -nf -- gifview -w WID $1 -a
    
    exit 0
    Save this file as gifbg.sh and let's not forget to make it executable:
    Code:
    chmod +x gifbg.sh
    Now when we can make our background move:
    Code:
    ./gifbg.sh /path/to/animated.gif
    You'll probably want to start this script when you login so hit the gnome menu -> system -> preferences -> sessions hit Add and make up a name and copy the command into the appropriate box. Notes: You have to put the complete path to the script in here because gnome doesn't respect the $PATH variable. Also, for some reason the image will appear always on top when it's loaded from boot, one solution is to add a "sleep 5" on top of the script to make sure it loads after the rest of your desktop.

    There you go, an animated background using a few megs of ram and an imperceptible amount of cpu time.

    To stop the magic happening either Ctrl-C the command if you ran it from the terminal or hit Alt-F2 and type:
    Code:
    killall xwinwrap
    To uninstall:
    Code:
    sudo rm /usr/bin/xwinwrap

    This is a little different than the animated gif but I think it is interesting.

    http://gnome-look.org/content/show.p...?content=83443

    Basically you make an xml file as the background that refers to the pictures of choice. It changes over time. The artist set it up to look like the sun moving in the sky.

    I have one in the works and will upload it to gnome-look when its done. So keep a look out.

    Re: HOWTO: Animated background

    I wasn't able to get this to work in Ibex. Just getting the branch downloaded from launchpad was pretty complicated (had to create a gpg and ssh key). After downloading the folder I wasn't able to make it.

    winwrap|$make
    gcc -Wall -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wredundant-decls -lX11 -lXext -lXrender xwinwrap.c -o xwinwrap
    mkdir x86_64
    mv ./xwinwrap ./x86_64
    gcc -m32 -Wall -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wredundant-decls -lX11 -lXext -lXrender xwinwrap.c -o xwinwrap
    mkdir i386
    mv ./xwinwrap ./i386
    winwrap|$sudo make install
    make: *** No rule to make target `install'. Stop.
    It's really too bad, I was about to use the hypnotoad gif.

    @ Whitethorn:

    This happened to me too. All that has happened is that the winwrap ececutable file hasn't been moved to /usr/bin, which isn't too much of a problem. You could move it or alter the script to direct to the file. Depending on your architecture the file to direct to is in i386 or x86_64 in the winwrap directory.
