I have no idea: Doom.CS

image = new IMG256Colours (100, 100, pal, 256);
					for (int i = 0; i < 4; i++) {
						int offset = i * (25 * 25);
						for (int x = 0; x < 25 * 25; x++) {
							byte colour = 0;
							if (i == 0)
								colour = 160;
							else if (i == 1)
								colour = 112;
							else if (i == 2)
								colour = 240;
							else if (i == 3)
								colour = 250;

							image [x + offset] = colour;
						}
					}
