RE: anti-aliased plots

 Hi Anton,

[Fine, Valeri]
It is possible to do that with Qt-plugin http://doc.qt.nokia.com/4.7/qpainter.html#RenderHint-enum One needs to add one line into the TGQt.cxx code to set . At the time it swallowed too much CPUs and our users were inpatient and wanted to be fast. I did not try it yet, but you .... may try ;) I think that flag exists for the other ROOT graphical engines too.

>(without any external tools)
 Umm, Qt plugin is the external tool though.

Cheers, Valeri
