[Kde-extra-gear] kgraphviewer: export to image: actual command line behind the scenes

[Kay Kay]

I am using kgraphviewer to view a .dot and using "export to image" 
functionality that saves the graph as png.
The output quality is very nice with the anti-aliasing close to being 
perfect for the text values of the nodes.

I tried the same in the command-line ( eventually for automation)  using 
the dot command as - "dot -Tpng  <input file> -o output.png" . This did 
not give the same result as the previous "export" command.
I am just curious what other extra options that kgraphviewer had invoked 
for the export functionality ( especially with anti aliasing).

Thanks for the help.
