Posted: August 27th, 2008, 5:20 am

Hey I'm writing a script and speed could be very important I'm not sure yet. I'm wondering how slow is the PixelGetColor function, would 20 pixelGetColor calls in a row take > 1 second on standard hardware?

I know the question is quite ambiguous since it depends on machine to machine, just looking for guidelines

Why not try it for yourself?

Code:

Start := A_TickCount
Loop, 20
   PixelGetColor, var, 1, 1
MsgBox % "20 PixelGetColor calls took " (A_TickCount - Start) "ms"

(oh, and the answer is no. It took my crappy old computer 350-400ms for 2000 pixelgetcolor calls)

i got "20000 PixelGetColor calls took 375ms"

375/20000 = 0.018750ms / pixel

it's not slow
