PixelGetColor - MouseMove - ClientWindow

[Albireo]

My desire is to read the color in all pixels in a line on an open window.
Something like that .:

eg. PixelGetColor

Code: Select all

…
xPos = 100
yPos = 100
CoordMode Pixel, Client
Loop 100
{	xPos1 := xPos + A_Index - 1
	yPos1 := yPos
	PixelGetColor PixelColor, %xPos1%, %yPos1%, Slow RGB
	FileAppend % xPos1 "`;" yPos1 "`;" PixelColor  "`n", %LogFil%, UTF-8
}
...

It work!
But I want the mouse to follow where the PixelColor is read.

It's not hard, if I only use the "Windows" coordinates - not the "Client" coordinates (to the active window)
Something like that .:

eg. MouseMove - PixelGetColor

Code: Select all

…
WinActivate %WinID%
xPos = 100
yPos = 100
Loop 100
{	xPos1 := xPos + A_Index - 1
	yPos1 := yPos
	CoordMode Pixel, Client	; CoordMode, ToolTip|Pixel|Mouse|Caret|Menu [, Screen|Window|Client]
	PixelGetColor PixelColor, %xPos1%, %yPos1%, Slow RGB
		
	CoordMode Mouse, Client	; CoordMode, ToolTip|Pixel|Mouse|Caret|Menu [, Screen|Window|Client]
	MouseMove %xPos1%, %yPos1%
}
...

The window is activated, and I got some colors, but can't see any mouse in movement on the active window...

Is there a risk that the mouse cursor may interfere with PixelGetColor? (or ToolTip?)
Must the CoordMode be set all the time? (CoordMode Mouse ... / CordMode Pixel ...)


From the help file.:

Code: Select all

DllCall("SetCursorPos", int, 100, int, 400)  ; The first number is the X-coordinate and the second is the Y (relative to the screen).

Moving the mouse with the instruction above, can it operate on the active windows coordinates? (or only the coordinates of the screen)
