Thanks for yours answers, 32bit doesn't lose quality. it also easily suports an inline alpha channel. 16bit does not. you need to do a separate alpha plane. also its lower quality. the software enigne is 32bit. also remember evas's dfb engine is very much a 2nd class citizen and is mostly not maintained. > Stéph > > > --------------------------------- > Découvrez une nouvelle façon d'obtenir des réponses à toutes vos questions ! > Profitez des connaissances, des opinions et des expériences des internautes > sur Yahoo!
