Comment puis-je configurer un fond d'écran à défilement horizontal?
Je veux que mon fond d'écran soit un défilement latéral de L'île 1 de Super Mario World, Yoshi . Une fois que le papier peint a fait défiler tout le chemin, il se fond parfaitement au début.
Existe-t-il un programme, ou XML, qui accomplirait cela pour moi? J'utilise GNOME Shell.
Mise à jour du 22/10/16
Le script a été mis à jour pour répondre aux exigences de cette question: https://askubuntu.com/a/840381/295286
La transition et la durée sont devenues facultatives et ont des valeurs par défaut. L'option -s est également ajoutée pour le dimensionnement des fonds d'écran (comme les options Mosaïque, Échelle, Étirement des Paramètres système).
Comme je l’ai dit dans les commentaires, vous devez découper l’image en morceaux de même taille ou se chevauchant et créer un diaporama. Je ne connais pas la licence de cette image spécifique que vous souhaitez, je vous laisse donc le soin de la couper ( Hint ).
Cependant, voici un script de générateur de fond d'écran animé que j'ai écrit. L'utilisation est très simple. Comme le montre l'option -h:
usage: xml_wallpaper_maker.py [-h] -d DIRECTORY -t TRANSITION -l LENGTH [-o]
Serg's XML slideshow creator
optional arguments:
-h, --help show this help message and exit
-d DIRECTORY, --directory DIRECTORY
Directory where images stored
-t TRANSITION, --transition TRANSITION
transition time in seconds
-l LENGTH, --length LENGTH
Time length in seconds per image
-o, --overlay Enables use of overlay transition
Exemple:
./xml_wallpaper_maker.py -d Pictures/My_SideScroller_Images/ -t 5 -l 10
