Scaling according to Position
In the beginning, the image will be in the center box and its size will be Wf and I can drag it to left/right/up/down. Its size will change according to the logic of the image I attached. As this scaling will depend on the position I can’t figure out how to do it. How can I achieve my desired result?

I’m not sure it’s exactly right, but probably something like this:
wm = 50;
wf = 150;
R = wf/Math.SQRT2;
center = [thisComp.width,thisComp.height]/2;
r = length(position,center)
ws = linear(r,0,R,wf,wm);
[ws,ws]

Thanks, it’s almost working but what if I don’t want the center value as the center of the composition. I want it something like [200,300] as I declare. Do you have any idea how to do that?
-
I tried it like “center = [100,300];” this. But then the whole code is not working.

That works for me. In what way is it not working for you?
-
yeah,it worked..thank you so much
This is how achived it:wm = 100;
wf = 496;
R = wf/Math.SQRT2;
center = [540.7397,627];
r = length(position,center);
wa=wf+((r/R)*(wm-wf));
ws = linear(r,0,R,wa,wm);
[ws,ws]
