Q: perl's equivalent to some AutoIT's functions

Hi

I have been doing some AutoIT scripting these few days and find it, great.
However, I prefer to program on my "native tongue".

Here are some questions that I need out of perl that I am doing with Autoit.
Is there a Perl equivalent to:

AutoIt's PixelGetColor
AutoIt's PixelSearch
and a DLL call that scans the current displayed screen with a given grahics
file.

I am not referring to getting pixel color off a static graphics file, but
rather the dynamic displayed screen.

Thanks.
Dan
