Composite Effects - resize/resizing one of Paint/Paints

Hello,

I have a compositePaint:

 local compositePaint = { type="composite", paint2={ type="image", filename="image/masks/con\_iced.png"}, paint1={ type="image", sheet=mySheet,frame=10 } }

But I needed to use paint2 resized to fit paint1. Is there any params to do so?(2) Does it possible?(1)
