Difining Interest Areas

Olya

Hello!
In my experiment, I have a bunch of photos of faces in one sketchpad item in one loop. I need to define a different interest area (eyes, nose, mouth) for each face. I added inline_script above the sketchpad. In the inline script, I wrote:

exp.eyelink.log ("!V IAREA FREEHAND <x1, y1>, <x2, y2> nose")

I am thinking I will keep adding this line but changing the id(different for each photo) and coordinates(depends on face part)

The problem is I don't know how to get the absolute coordinates for each photo.

Also, how do I set an integer id for each photo as well?

Thank you very much.
