在MacOS中获取屏幕的物理尺寸

您应该可以从中获取此信息 CGDisplayScreenSize ,根据文档返回“以毫米为单位的指定显示的大小”。

这个 Quartz Python库似乎有一个绑定:

from Quartz import CGDisplayScreenSize, CGMainDisplayID

display_id = CGMainDisplayID()
dimensions = CGDisplayScreenSize(display_id)
print(dimensions)

您可以使用 Quartz. CGDisplayScreenSize :

以毫米为单位返回显示的宽度和高度。
func CGDisplayScreenSize(_ display: CGDirectDisplayID) -> CGSize

import Quartz

def main() -> None:
    main_display_id = Quartz.CGMainDisplayID()
    width_mm, height_mm = Quartz.CGDisplayScreenSize(main_display_id)
    print(f'{width_mm = :.2f}, {height_mm = :.2f}')

if __name__ == '__main__':
    main()

使用M1 Macbook Air的输出示例:

width_mm = 286.87, height_mm = 179.29
