如何设置横向滚动壁纸？

我想让我的壁纸成为超级马里奥世界耀西岛1的侧卷。 一旦壁纸一直滚动，它将无缝循环回到开始。

是否有一个程序或XML可以为我完成这个任务？ 我正在使用GNOME Shell。

该脚本已更新，以符合此问题中的要求： https ： //askubuntu.com/a/840381/295286

转换和持续时间是可选的，具有默认值。 还添加了-s选项以调整壁纸大小（与“系统设置”中的“平铺”，“缩放”，“拉伸”选项相同）。

就像我在评论中所说的那样，你必须将图像缩小为均匀或重叠的部分并为其创建幻灯片。 我不知道你想要的特定图像的许可证，所以我会留给你剪切它（ 提示 ）。

但是，这是我写的动画壁纸生成器脚本。 用法很简单。 如-h选项所示：

 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 

例：

 ./xml_wallpaper_maker.py -d Pictures/My_SideScroller_Images/ -t 5 -l 10 

源代码
