macOS How can I detect screen rotation on mac?

Is it possible to detect screen rotation? I'm woking on the touch screen driver on mac, so I want to know if the screen is rotated.

Any ideas? All help is appreciated! Regards

i dont know for sure but i assume you could do this applescript

screenWidth to word 3 of (do shell script "defaults read /Library/Preferences/com.apple.windowserver | grep -w Width") as number

set screenHeight to word 3 of (do shell script "defaults read /Library/Preferences/com.apple.windowserver | grep -w Height")

i got this from here Basically i think just quering the OS for screen size then say (sudo code)

if width > height
im rotated
else
im not

Try CGDisplayRotation.

Thanks for your reply! This script can detect the screen rotated. But I can not determine whether it rotates left or right.
