Constructor Detail

Visualizador

public Visualizador(String caminhoImagem,
                    Frame frame,
                    String titulo)

Construtor da classe. Abre a janela popup com a foto. Recebe um frame para inclusão, nome da foto e um título para a janela. Testa se é necessário redimensionar a foto, caso positivo chama a função calculaRedução. Implementa um botão para fechar a janela e por último mostra a tela ao usuário.

Parameters:

caminhoImagem - Caminho da foto.

frame - Janela frame para alocar a foto.

titulo - Título da janela.

Method Detail

calculaReducao

public static Dimension calculaReducao(Dimension original,
                                       int tamMaximo)

Faz uma redução de dimensão da foto. Recebe um valor de dimensão e um tamanho máximo. Faz um cálculo baseado na divisão da largura pela altura para saber se a imagem está na vertical ou na horizontal, então calcula e retorna a nova dimensão.

Parameters:

original - Dimensão original.

tamMaximo - Tamanho máximo da nova dimensão.

Returns:

Retorna a nova dimensão.

paint

public void paint(Graphics g)

Faz uma chamada a classe base e pinta todos os componentes. Esse método não é utilizado. TODO: avaliar a funcionalidade deste método.

Overrides:

paint in class Window

Parameters:

g - Contexto gráfico.

actionPerformed

public void actionPerformed(ActionEvent e)

Desabilita a tela. Desabilita sua visibilidade e encerra seus dados. Esse método não é utilizado. TODO: avaliar a funcionalidade deste método.

Specified by:

actionPerformed in interface ActionListener

Parameters:

e - Evento de ação.

main

public static void main(String[] a)

Método principal. Cria um objeto Dimension e seta seus valores. Logo após utiliza o método calculaRedução da própria classe para reduzir a dimensão original. Ao final, imprime as duas dimensões.

Parameters:

a - args do método main.
