EgtGeomKernel/CurveBezier.h
T
Dario Sassi 41a38fef3b EgtGeomKernel 1.5f1 : 
- aggiunta entità testo (con font Nfe e di sistema)
- in tutte le rotate ora l'angolo è in gradi
- aggiunta trasformazione Shear (scorrimento)
- aggiunta trsformazione LocToLoc
- Set/GetInfo specializzate per i diversi tipi di informazioni
- Copy e Relocate con possibilità di indicare l'entità di riferimento rispetto a cui inserire
- aggiunte trasformazioni a PolyLine.
