Mask and Multipass Toolbox

Hi

I have been looking at this as a replecement for the surface mask creator I use. Does this have a seting for changing the size of the mask to match the render? 

For instance if my my render is 6000x4000 pixcels can I make the mask render the same size as this?  I need this to happen really and the surface mask creator does that automatically when you set the render size.

I assume it does of course just checking it works the way I am used to doing things;)

cheers
