Pixel Search problem or bug

Recommended Posts



I think pixelsearch has a bug or something because I have a problem that is killing my mind.

So I use the following code 

$x = 1500
$y = 1000
$iColor1 = PixelGetColor($xp, $yp)
&hex = Hex ($iColor1, 6)

$aCoord = PixelSearch($x,$y, 2,2 ,$hex, 10)
If Not @error Then
    MsgBox($MB_SYSTEMMODAL, "", "X and Y are: " & $aCoord[0] & "," & $aCoord[1])

I get all the time the message that x and y are something like 200, 300.

Why is this happening? Can be because 

color Color value of pixel to find (in decimal or hex).

should have 0x at the 

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

This code won't even run as written here. &hex needs to be $hex.

By the way, you don't need to convert the color to hex, just use the decimal number you get back from PixelGetColor.

Where are the variables $xp and $yp coming from?

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

there was a mistake with the  &hex needs to be $hex.  when i made the code for the topic. Not this is the problem


$x is made by something like $originex - 100

y is made by something like $originey + 25

$originex and $originey are big numbers, more then 1000,


The ideea is that I want to check if 2 areas if they are the same color (the problem is that there are some little variance on color)


Each area can have 4 color (red, green, black and blue). There can be some case were both area are the same (red red, black black), Even if the areas are the same there is a little diference in color so I cannot use decimal code and check if they match or not.


I tried to use decimal code with some tolerance when checking but not working because the difference between black and blue for ex is not the same as the diff between red and green. (i mean the value, the number).


How I can do this?

No, I cannot hook in the control.


And why you say I should avoid Pixel Search? I want to use it only for searching in a small square 2x2 or something like that.
