Description Bartek Pietrasiak 2009-11-05 02:26:53 UTC 
Version:           1.0.0-beta6 (rev.: 1044916) (using 4.3.2 (KDE 4.3.2), 4.3.2-4.fc11 Fedora)
Compiler:          gcc
OS:                Linux (i686) release 2.6.30.9-90.fc11.i686.PAE

I've tried a few times with using 1 and 9. The produced png was always 3,5 mb  (on file system ;).
