Tela de abertura com efeitos

Alguem saberia me dizer se é possível mostrar uma imagem, enquanto o programa é carregado, que imitasse aquele efeito de transparência que ocorre com programas do tipo discador IG. Ou melhor, gostaria de exibir uma imagem que não fosse retangular, e tivesse o efeito de transparência. :shock:

A Java2D (e, por consequencia, a Swing) tem suporte a PNGs transparentes. Eh soh exibir um PNG quadrado num frame sem bordas :slight_smile:

Desculpe a ignorância. O que seria PNG ?

formato de foto…
tipo tem… gif… jpg…

Nao, eu nao desculpo!
