This option allows the user to create zones as per the user's requirement.
User's can use different shapes provided in the predefined shape section (like line, triangle,trapezoid, parallelogram etc) or can also use custom button to customize the zone shape as per his/her choice and create a zone.
Once the zone is created, the json for it will be generated in the json section which can be copied and added to a new json file under sample/conf section in the Nimble.
So this new json can be added in the Nimble config.yaml file in pipeline section of desired usecase to have the zone updated accordingly on that usecase video channel as per the configuration done.
The dimension i.e height and width of the video channel can be changed according to user's choice by changing the height and width values in the dimensions section.
