":subsample=>'5 5'" cannot be acceptable, because each value 
of the argument must be one token on the Tcl/Tk command. 
But ":subsample=>[5, 5]" is acceptable on Ruby1.8.2 release.

If you want set options without value on Tcl/Tk, please give true 
for each of the options (e.g. a.read('image.gif', :shrink=>true.))
