壁纸幻灯片软件，支持更改图像大小
我发现了几个创建幻灯片的软件应用程序，但我还没有看到一个支持更改图像大小的软件应用程序（即适合，拉伸，填充宽度，填充高度）。 有没有支持这个的软件？
介绍
这就是：如果你在终端dconf watch /运行dconf watch /并同时在Ubuntu设置中翻转壁纸大小（平铺，缩放，缩放等）中的选项，你会看到：
/org/gnome/desktop/background/picture-options 'zoom' /org/gnome/desktop/background/picture-options 'wallpaper' /org/gnome/desktop/background/picture-options 'centered' /org/gnome/desktop/background/picture-options 'scaled' /org/gnome/desktop/background/picture-options 'stretched' /org/gnome/desktop/background/picture-options 'spanned'
这是什么意思呢 ？ 这意味着如果你有一个可以翻阅壁纸的软件，它也应该可以翻阅这些选项，对吗？
好吧，我之前写过一个壁纸幻灯片剧本 。 在过去，它需要选择。 对于您的具体问题，我修改了脚本以处理大小，并且只需要一个选项-d ，它对应于幻灯片图像应该存在的目录。
基本用法
用法很简单：给它带有图像的目录，给它大小，然后运行。 就像这样简单：
$ ./xml_wallpaper_maker.py -s zoom -d ~/Pictures/wallpapers/
您始终可以使用-h选项显示额外选项的帮助信息，以防您忘记使用情况：
$ ./xml_wallpaper_maker.py -h usage: xml_wallpaper_maker.py [-h] -d DIRECTORY [-t TRANSITION] [-l LENGTH] [-o] [-s SIZE] Serg's XML slideshow creator optional arguments: -h, --help show this help message and exit -d DIRECTORY, --directory DIRECTORY Directory where images stored. Required -t TRANSITION, --transition TRANSITION transition time in seconds, default 2.5 -l LENGTH, --length LENGTH Time length in seconds per image, default 1800 -o, --overlay Enables use of overlay transition -s SIZE, --size SIZE wallpaper,zoom,centered,scaled,stretched,or spanned
脚本来源
脚本源在此处和GitHub上都可用 。 如果您有git ，请随意运行git clone https://github.com/SergKolo/sergrep.git或从上面的链接下载存储库文件。 如果您要从此处复制，请确保将文件另存为xml_wallpaper_maker.py并使用chmod +x xml_wallpaper_maker.py使其可执行。
