Compare Y axis values in 2 pixel search

[IHAT]

I’m using PMC since long and doing great with it.
Lately I came to a challenge that I can’t solve.
I need to do a pixel search for 2 items after I need to compare the Y axis values + or - based on that a mouse action to trigger, I mean if the item1 is higher in the Y axis value compared to item 2 the mouse action to trigger and vice versa
If usually we have 4 values (x1, y1, x2, y2) coordinates I want to compare y1 value of both pixels only
Hope someone to give me a hint on how to approach that using Pullover’s not the AHK
I posted by mistake on the general AHK will delete it
