在Windows中使用python安装字体

Question

我正在开发一个python脚本来安装Windows中的字体列表.我有这样的清单,

fonts_list = ["/path/to/file/myFont1.ttf", "/path/to/file/myFont1.ttf", "/path/to/file/myFont1.ttf"]

我只是尝试使用shutil和os复制字体文件,之后我尝试将其添加到Windows注册表中,即使使用管理员权限,它也无法正常工作.脚本的输出没有显示任何错误,但列表中提到的Windows Fonts目录中没有任何字体.

os.system(reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts" /v "FontName (TrueType)")

所以我开始从网上寻找更多的种子然后我找到了这个,用python在Windows上安装TTF字体.但它也没有用.接下来我尝试调用Windows fontview.exe,但是对于字体列表来说这是一场灾难.

os.system("fontview " + fontsList[0])

无论如何都要以编程方式在Windows中安装字体？或者Windows中是否有任何用户级目录只是复制字体文件,如Linux系统有〜/ .fonts和Mac有〜/ Library/Fonts？请帮忙.

Answer 1

这是install_font将字体复制到系统Fonts文件夹,在当前会话中加载,通知正在运行的程序以及更新注册表的功能.它只依赖于Python的标准库,并且应该同时适用于Python 2和3.
