Question about screen resolution

Settings:setCompareDimension(true, 1080)
Settings:setScriptDimension(true, 1080)
-------------------
I have set up the script like this. Is it accurate? Thank you

--copy everything you see in this post and save it as a .lua file. then run that file in ankukua while on the device you want to know.



local function screenSize()
local x = getRealScreenSize():getX()
local y = getRealScreenSize():getY()
print("Real Width: "..x)
print("Real Height: "..y)
print("Your actual device full screen resolution: "..x.."x"..y)
end

screenSize()

For example I want to limit image search to red area only. If yes, what can I use to get its location

How can I get the coordinates of the desired region?

I can only define the top area of ​​the screen, I can't start from the bottom

When I run the script it gives an error: User Abort! Admin please help me fix this script error. 

Settings:setCompareDimension(true, 720)
Settings:setScriptDimension(true, 720)
Settings:set("MinSimilarity", 0.6)
