thanks for your explanation. I started work again on the C++ wrapper for Evas and noticed Gradient2. So I'll omit it. Maybe it could be left on SVN for anyone who likes to work again on it, but disabled with a configure switch. Or move it into an OLD directory. regards Andreas > Andreas Volz wrote: > > > Hello, > > > > could anyone explain why there is a Gradient and a Gradient2 in > > Evas? > > > > I couldn't find and document that explains what are the advantages > > of one against the other.
