Consider the following example.
In[1]:= g = Plot[Sin[y], {y, 0, 6 Pi}];
In[2]:= ImageSize /. FullOptions[g]
Out[2]:= Automatic
How can I determine the *number* X (!= Automatic) such that the
graphic generated by Plot[Sin[y], {y, 0, 6 Pi}, ImageSize->X] looks
identical to g as defined in In[1]?
More generally, for any option that accepts Automatic as a possible
value, how can I determine the whether there exists some value X
(distinct from Automatic) such that specifying X as the value of
this option would produce exactly the same results as specifying
Automatic, and if so, how can I determine this value?
Thanks!
