Feature(?): Grab only app's frame

[mnfro]

General information:

• OS name: macOS Catalina
• OS version: 10.15.4
• Python version: 3.7.7
• MSS version: last

Description

Is there a way to capture only the frame of a specific app window? I mean with built-in macOS screencapture, I can do something like this to get a screenshot of a particular app:

os.system("screencapture {options} -l {window} {filename}")

where {window} represents the windowID of the app, in my case QuickTime Player app ID (obtained from Quartz).

Being able to specify which app I want to take the screenshot of would result in a more flexibility, as I can move the app window wherever I want and I don't need to set any kind of boundary (top,left,width,height).

cheers, mate!

Hey,

Yes, it would be cool to have it! Another thing on my TODO list ;)

You can write a while-loop, which gets the rectangle of the app via his PID - this rectangle you can set as argument on the mss.grab function.

I just wrote a solution for this request here #180 and it is indeed possible. I am currently attempting to edit this library to provide the function, but I am not sure how far I will progress on my own :P
