conky slideshow script

[k3ttc4r]

so.. i created a script that let's you have a slideshow with conky. right on your desktop!

of course this is on my site, too, for all you german speaking folks out there: http://linuxian.net/artikel/conky-teil-3-slideshow-script.html

just configure this under "settings", save it, chmod +x it, change in the directory with the images you want to use (in a terminal, of course), and execute the script. it takes care of all the rest, you just have to call it in conky with

${execi 600 ***DIRECTORY YOU USED IN THE SCRIPT***/slideshow}
${image ***DIRECTORY YOU USED IN THE SCRIPT***/current.png}
#!/bin/sh

let me know what you think, if you have any improvements, suggestions, request..

and have fun with it!

Nice code, I don't use conky anymore but maybe I will reuse some of your code somewhen somewhere :D

btw, wenne magst und jabber hast loomsen <at> lethyro.net, oder 123 866 981 für i seek you

*edit*
I'd rather use


# Converts the image files for conky to use
cp -v * $directory/pics
mogrify -format png -resize $geometry $directory/*
rm -v -f $directory/*.jpg


than


# Converts the image files for conky to use
cp -v * $directory/pics
cd $directory/
mogrify -format png -resize $geometry *
rm -v -f *.jpg


If you need to change a directory pushd and popd will handle this very well inside your script instead of cd

TRY THIS and make your comments
Note: yo need to have images(either jpg OR png) in ~/Pictures Folder
and convert from imagemagick

~/.conkyrc

alignment tr
own_window yes
own_window_transparent yes
own_window_type override
gap_x 10
gap_y 120
minimum_size 160 0
maximum_width 160
update_interval 5.0

TEXT
${exec cd ~/Pictures; /usr/bin/convert -format png -resize 160x120 "`/bin/ls *.png *.jpg 2>/dev/null | /usr/bin/shuf -n1`" /dev/shm/current.png}${image /dev/shm/current.png -p 0,0 -n}${voffset 100}

Hi there, I just would like to contribute to this forum by adding the following code which is shorter and works well. The bash file (slideshow.sh) is in the folder /slideshow and within the same folder (/slideshow) I created the sub folder /pictures (/slideshow/pictures) which contains all the relevant pictures.
Here are quick explanations of the code:

ls -1 $dir/pictures -> list one picture per line, the picture in my case has a jpg extension.

sort --random-sort -> randomly sort the pictures. The first picture of the list is randomly chosen

head -1 ->only keep the first randomly listed picture

mogrify -frame 100 -format png -resize $geometry -write $dir/model.png $dir/pictures/$file -> resize picture and save it in the folder /slideshow next to the bash file (slideshow.sh)

Conky calls the script (slideshow.sh) and creates/updates a picture called model.png in the folder /slideshow which further appears in the conky side bar on the desktop. Be aware that the -p is for the position of the picture and the -n is very important for the update of the picture.


----------------------------
/.conkyrc
${execi 50 /home/user/scripts/slideshow/slideshow.sh}
${image /home/user/scripts/slideshow/model.png -p 70,790 -n}

----------------------------
#!/bin/sh
# conky slideshow by G. 2010
dir="/home/user/scripts/slideshow" # Directory
geometry="200x200" # Max Geometry of the pictures in the slideshow
file=`ls -1 $dir/pictures | sort --random-sort | head -1`
mogrify -frame 100 -format png -resize $geometry -write $dir/model.png $dir/pictures/$file
#echo "The randomly-selected file is: $file"
exit

---------------------------

If you want to add new pictures just drag it in the folder /pictures at any time. Any kind of pictures should do the job. If you have any comment or questions, feel free to ask.
