Witam, zacząłem bawić się w NetBeansie javą i stworzyłem program który po wciśnięciu przycisku ładuje wybrane przez nas zdjęcie, otwiera je w oryginalnych rozmiarach ale nie mogę sobie dać rady ze skalowaniem tego obrazka.Chodzi mi o kod który sprawia, że zdjęcie rozciąga się z zachowaniem proporcji, proszę o pomoc Oto kod:
