Hello,

Please format your code as per:  
[https://discourse.processing.org/faq#format-your-code](https://discourse.processing.org/faq#format-your-code)

This is the same code as you provided here:  
[https://discourse.processing.org/t/help-with-error-in-robot-class-and-createscreencapture-method/30396/1](https://discourse.processing.org/t/help-with-error-in-robot-class-and-createscreencapture-method/30396/1)

_ **I provided you with a link in the topic above to a working example that you can modify to get a PImage of the screen.** _

Please correct your code and then take the next step.

Once you get a PImage you can use get():

See tutorial:  
[https://processing.org/tutorials/pixels/](https://processing.org/tutorials/pixels/) _Intro To Image Processing_ section has a good example to work with!
