Just to add something.  What I really like to obtain is the same effect as 
the following command


         Framed[ Plot[Sin[x], {x, -Pi, Pi},
                      Frame -> False,
                      ImageSize -> Scaled[1],
                      ImageMargins -> 0,
                      ImagePadding -> 0]
       ItemSize -> 20, Frame -> All

You can see the image (plot here) completely fill all the space. This is 
what I want.

But without the use of Scaled[], and without having to specify a numerical 
value for the plot ImageSize or width and hight. i.e. by only giving the one 
numerical value for the ItermSize, and the rest should be done Automatically 
just like the above, but again, without the use of Scaled. This way, I only 
need to change one value and not worry about different combinations 
affecting each others.

I am still trying different options, but none seems to work as Scaled[1]
