art-sharp 2.0.0.0 Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details. The Structure AlphaGamma supports a specific value of gama. The composition with an AlphaGamma parameter is equivalent to applying a gama transformation to source images, with a alpha composition done in linear intensity space, and then applying the inverse gama tranformation, to place it back on the gamma-adjusted intensity space. This is only true when its correctly implemented, wich isn't generally the case in libart implementation. System.ValueType Field Art.AlphaGamma To be added To be added Method Art.AlphaGamma To be added a a To be added Method Art.AlphaGamma Creates a new AlphaGamma with a particular gamma value. a a Method System.Void Frees any resouces that are held by this structure.
