13 posts in this topic

#1 ·  Posted (edited)

For example i have a pixel that can change its color in a huge color range. And i need to do some action when that pixel gets any color of gradient from black to white. Is it possible to use ane PixelGetColor or PixelSearch commands? Can u show me how to use them when i need to search for color range in 1 pixel

Create an Array with all possible Clors and the do

$isinColorrange = ArraySearch($colors,PixelGetColor(x,y))

Dim $Array[ NumberOfEntries ] = {Entry1,Entry2,...}

Or

Dim $Array[ NumberOfEntries ]

$array[0] = Entry 1

$array[1] = Entry 2

_ArraySearch is in the include Array.au3

Its impossible to set an array for all colors that are between white and black. there are thousands of colors.

Is there another way to search a pixel for a huge range of colors? May be something like:

PixelSearch (1, 1, 3, 3, (0xFFFFFF - 0x000000))

???

Maybe this way:

$x = PixelSearch()
$x = Hex($x,6)
$r = Stringleft($x,2)
$g = StringMid($x,3,2)
$b = StringRight($x,2)
If ($r = $g) and ($g = $B) Then
 ; Colors are gray, white or black.
Endif

This way you cant have Colors like 0xAAAAAB or ox000001

They must be oxFFFFFF or 0xDDDDDD or 0x111111 ... (Allcolors the syme value)

What do you mean search for any color?

Anything not greyscale?

If that is the case you can pixel scan that entire line from left to right for example, and when a pixelgetcolor returns a decimal that is outside the whites range, exitloop.

While 1
    For $Line = 1 To 300 ;length of the scan line in pixels
        If PixelGetColor($InitialPosition + $Line, 345) < 14777215 Then ;you've hit the color range you are after                           
            ExitLoop
            ExitLoop
        EndIf
    Next
    Sleep(10)
WEnd

I am not sure what your question means exactly but it looks like

study pixelsearch in the help

study pixelgetcolor in the help

Look at thread http://www.autoitscript.com/forum/index.ph...mp;#entry493137

1. Sample code to get all hex colors for a certain area

$startX=46
$endX=48
$startY=3
$endY=8
for $x=$startX to $EndX
   for $y=$startY to $endY
        consolewrite(hex(pixelgetcolor($x,$y)) & ";")
   next
   consolewrite(@CRLF)
next

2. Check if a certain color is in a certain range

if pixelGetColor($x,$y)>.... and pixelGetColor($x,$y)<....

3. You only can get a color of a certain location and have to check yourself for the right colors including the gradient

Search in the forum as some solution(s) are there all based on basic commands like pixelgetcolor, pixelsearch, bitblt, getDIBits, reading the bytes of the colors into an array and checking yourself.
