PixelChecksum Question

[jw102788]

My question refers to the PixelChecksum statement. I know that the statement is used to determine if the selected region has changed, then the script continues. Is there a way to use PixelChecksum to, instead of determining when the selected region has changed, to determine when the selected region has gone back to normal?

Thank You Very Much.

$checksum = PixelChecksum(0,0, 50,50)
; Wait for the region to change, the region is checked every 100ms to reduce CPU load
While PixelChecksum(0,0, 50, 50) = $checksum
  Sleep(100)
WEnd

MsgBox(0, "", "Something in the region has changed!")

; Wait for the region to change back, the region is checked every 100ms to reduce CPU load
While PixelChecksum(0,0, 50, 50) <> $checksum
  Sleep(100)
WEnd

MsgBox(0, "", "Region has changed back!")
