ImageNavigator es un componente que representa un manejador de imágenes. En él se puede desplazar, hacer un zoom out o un zoom in a una imagen virtual. El componente no trata la imagen en si, solo lanza los eventos indicando la nueva posición y zoom de la imagen, luego es el usuario el que se encargará de dibujar esa imagen en la posición correspondiente. El modo de uso es el siguiente: - Se puede desplazar una imagen con el botón izquierdo del ratón. - Se puede hacer zoom in/out con las teclas +/- del teclado. - Se puede hacer zoom in/out con la rueda del ratón teniendo en cuenta la posición del mismo. - Se puede resetear los valores con las teclas 'Espacio' o 0; - Las teclas 1, 2, 3, 4 y 5 equivalen a zoom 1, 2, 4, 8 y 16 respectivamente. - La tecla C sirve para centrar la imagen. - La tecla B sirve para mostrar u ocultar los cuadros del fondo. Útil para mostrar imagenes con transparencia. - La tecla H muestra la ayuda.
