X,Y coordinates for animating Hot Zoomer

I see my error in setting up the To: coordinates for the zoomer but I need examples or a link to a tutorial for guidance with x,y coordinates. See attached file - zoomer.jpg

Well format is like this:

X,Y,Zoom


X and Y can have values from 0.00 to 1.00, Zoom can have any positive value usually greater than 1.00

if you want your image to move from top-left to bottom-right values would be like this (no zoom):

from:0,0,1
to:1,1,1


if you would like to center image and then zoom 3x center of image ,

from:0.5,0.5,1
to:0.5,0.5,3.0

note that zoom is relative to view area.
