Generación de laberintos IV. Formato final 1024x768.


Código 1 (Blogspot_Laberinto_final.java):

package blogspot_laberinto_final;

import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;

public class Blogspot_Laberinto_final {

    public static void main(String[] args) {

        //tamaño laberinto (núm. bloques)
        int x = 21;
        int y = 29;

        //generar laberinto aleatorio
        String strMaze = new LineMaze(new BinMaze(new Maze(y - 2, x - 2).toString(), x, y).toMatrix(), x, y).toString();

        //tamaño lienzo
        int res_x = 1024;
        int res_y = 768;

        BufferedImage imagen = new BufferedImage(res_x, res_y, BufferedImage.TYPE_INT_RGB);
        Lienzo.Dibujar((Graphics2D) imagen.getGraphics(), res_x, res_y, strMaze);
        try {
