> I only use Athens to rendering the graphics framework :) And I try to not use directly some AthensCairo object to benefit of futur new backend of Athens :) and sincerely you really make a good job of the Athens interface! It's very easy to use it! In one case I use AthensCairo object. I have to use AthensCairoMatrix instead of AthensAffineTransform to represent the transformation of a shape because I have to make an inversion of the matrix to make a global position to the local position of the shape. >>>> -- > >>>> Best regards, > >>>> Igor Stasenko. > >>> > >>> > >> > >> > >> > >> -- > >> Best regards, > >> Igor Stasenko. > > > > > > > > -- > Best regards, > Igor Stasenko. > >
