Identifying HUD pixels

[justasecond]

Hi,

Excuse me if this has been covered before (I have looked hard) but I am attempting to use AutoIt v3 Window Info. to determine the properties of pixels. All is well until I come across the output of an on screen HUD which appears not to have a discernable properties i.e. Window Info cannot find its title (if indeed it has one) and does not recognise the existance of the superimposed on screen HUD information, colour or text (all of which which I guess has some sort of transparent property).

As a consequence, I am (so far) unable to write a program in AutoIt so that the superimposed HUD pixel properties can be acted upon, because as far as AutoIt is concerned they do not seem to exist.

As a footnote the HUD is a third party program.

Any observations/help would be most welcome.

Thanks
