/**
|
| 47 |
* <code>ImageNavigator</code> es un componente que representa un manejador
|
| 48 |
* de im?genes. En ?l se puede desplazar, hacer un zoom out o un zoom in a una
|
| 49 |
* imagen virtual. El componente no trata la imagen en si, solo lanza los
|
| 50 |
* eventos indicando la nueva posici?n y zoom de la imagen, luego es el usuario
|
| 51 |
* el que se encargar? de dibujar esa imagen en la posici?n correspondiente.
|
| 52 |
*
|
| 53 |
* El modo de uso es el siguiente:
|
| 54 |
* - Se puede desplazar una imagen con el bot?n izquierdo del rat?n.
|
| 55 |
* - Se puede hacer zoom in/out con las teclas +/- del teclado.
|
| 56 |
* - Se puede hacer zoom in/out con la rueda del rat?n teniendo en cuenta la
|
| 57 |
* posici?n del mismo.
|
| 58 |
* - Se puede resetear los valores con las teclas 'Espacio' o 0;
|
| 59 |
* - Las teclas 1, 2, 3, 4 y 5 equivalen a zoom 1, 2, 4, 8 y 16 respectivamente.
|
| 60 |
* - La tecla C sirve para centrar la imagen.
|
| 61 |
* - La tecla B sirve para mostrar u ocultar los cuadros del fondo. ?til para
|
| 62 |
* mostrar imagenes con transparencia.
|
| 63 |
* - La tecla H muestra la ayuda.
