PixelGetColor Problem

[torels]

Hi there

Does anybody know why if I use pixelGetColor on blue pixels (any variation of blue) the returned value is a red Color and viceversa ?

thanks in advance

AutoItSetOption( "ColorMode" , 0 )

;0 = Colors are defined as RGB (0xRRGGBB) (default)

;1 = Colors are defined as BGR (0xBBGGRR) (the mode used in older versions of AutoIt)

;2008-07-02(Wed) - AutoIt v3 removed this OPT.

Most of your problem, showed in AutoIt Help :-)

and how do I solve the problem considering that ColorMode opt doesn't exist anymore ?

I tried swapping blue and red but I get an inverted color then...

Can't see what's wrong, try post a code snippet.

$var = PixelGetColor(1, 1)

ConsoleWrite(Hex($var, 6))

Returns: 035EE9

Global $handle = DLLCall("user32.dll","long","GetDC","hwnd",0)

For $x = 0 to @DesktopWidth
    For $y = 0 to @DesktopHeight
        PixelDraw(@DesktopWidth - $x, $y,PixelGetColor($x, $y))
    Next
Next        
        
Func PixelDraw($XCoord, $YCoord, $Color)
   DllCall("gdi32","long","SetPixel", "long",$handle[0], "long", $XCoord, "long", $YCoord, "long", $Color)
   If @error = 1 Then
      Return 0
   Else
      Return 1
   EndIf
EndFunc

reflects the screen

All blue elements turn red and all red elements turn blue

using Hex(PixelGetColor($x, $y),6) color seems to be inverted.

GetPixel( hDC , ( int )x , ( int )y ); // returns RGB( r , g , b )

SetPixel( hDC , ( int )x , ( int )y , (char)RGB( r , g , b ) );
