PixelSearch Optimalize small area

[oSamplex]

"PixelSearch(0, 0, 0, 50, 0xFF0000, 25)"

The time it takes for this Search is around 15-30ms.
However increasing the Search area by quite some results that this search time is not increasing
So im wondering if there are any other techniques to accomplish a faster search time for this little 1x50 area? (Im hoping to achieve 5-15ms)

Thanks in advance.

I'm not sure that there is an "optimization" as such. What type of window or control are you looking for? Most people eventually leave PixelSearch behind for other methods, as there are much easier ways to accomplish window manipulation.

However increasing the Search area 

How you increase this area ? any example ?

Agreed. What is the name of the application? I'm sure somebody here has already coded what you need and no point reinventing the wheel.

Thanks,

Im trying to figure out if there is any faster way to detect a certain colored pixel in an area.
The thing is now that the size of this area does not have a big effect on time to find result and the area I'm searchin in is only 1x50,

so it feels like a lot of wasted process time. So I hope I can reduce it, if there is an other way with pixel detect.

I hope this clears it up.

PixelSearch ( left, top, right, bottom, color [, shade-variation = 0 [, step = 1 [, hwnd]]] )
PixelSearch(0, 0, 0, 50, 0xFF0000, 25)

PixelSearch ( left, top, right, bottom, color [, shade-variation = 0 [, step = 1 [, hwnd]]] )

PixelSearch(0, 0, 0, 50, 0xFF0000, 25)

 

I ask you how you increase this area.

I asked for your code, not what HelpFile says.

btw.

Please answer to other members question because they have right.

I dont think him increasing the search area is an issue. He wants faster results for his small area of search.

I think he is saying that a 50X50 search area rakes 15-30s and a 100x100 search area also takes his PC 15-30s more or less.

 

Does this pixel popup in a random location within this 50x50 search area? If not reduce the search size to just the location the pixel appears in.

What is the purpose of the function? There maybe other methods that are faster in some instances depending on what you are interacting with.

@Shane0000

You understand me, thanks for that.

I already narrowed the area down where the pixel can popup, but this has no effect on process time compared to let's say 100x100 (I use 50x1 at this moment)
It stays around 15-30ms which keeps me wondering if there is any faster way, because it's quite a bit.

You are only selectively answering questions, which must be answered to get the best response.  Go through prior posts, and respond to all questions.

oSamplex,

 

You are only selectively answering questions

Indeed - but these are some questions you had best answer promptly.

 

- Why the requirement for such speed of execution?

- Why the requirement for "shade-variation"?

- The coordinates you give (0, 0, 0, 50) are a single line of pixels down the top left side of the screen - why such a limited area?

Over to you.

I second this. I'm hoping I can learn something new here.

I've runned some tests with PixelSearch/PixelGetColor and they have as result they are quite slow to my taste 17-30ms.
If there is no other library that might be faster or something else pixel-wise that could speed it up, I will accept it.

I'm sure that I do rely on pixel detection on screen, so I'm not bothering answering questions about if it can be done without 'pixels',

so I'm sorry if you feel different about that.
 

$times = 100

$total = 0
For $i = 0 To $times
   $timer = TimerInit()
   Local $iColor = PixelGetColor(0, 50)
   $timer = TimerDiff($timer)
   $total = $timer + $total
Next
   ConsoleWrite("'PixelGetColor' Average Time: " & $total / $times & "ms" & @CRLF)

$total = 0
For $i = 0 To $times
   $timer = TimerInit()
   Local $aCoord = PixelSearch(0, 0, 50, 0, 0xFF0000, 60)
   $timer = TimerDiff($timer)
   $total = $timer + $total
 Next
 ConsoleWrite("'PixelSearch' Average Time: " & $total / $times & "ms" & @CRLF)

;~ Average search time 17-30ms of PixelGetColor and PixelSearch,
;  but PixelGetColor has to be done multiple times to achieve the search area.
;  My conclusion is that Pixel searches has some serious delay,
;  where no other function exicst to replace to detect a pixel in an area.

oSamplex,

 

so I'm not bothering answering questions

So we are not bothering giving answers. Thread locked.
