I need to read a graphic file and know if  a determinate point  the color is green.

If the graphic is in the screen I can use   PixelGetColor().

Can I read the graphic whitout show it in the screen?

I don't have all the exact commands in my head at the moment, but you can do it with something like.

#include <GDIPlus.au3>

; Initialize GDI+ library

; Some color, maybe even 0, 0, 0 black
$pixelDave = 4278190080
$hBMP = _GDIPlus_BitmapCreateFromFile($rect_file)
If _GDIPlus_BitmapGetPixel($hBMP, $x, $y) <> $pixelDave Then
    ConsoleWrite("Dave's not here")

Something like this does what you want to do.
