	pynter.py genera una imagen basándose en una cadena conteniendo una sucesión arbitraria de 25 unos y ceros. Cada cadena concreta tiene su propia imagen única.

	pynter.py está ideado para ser usado como módulo en otros programas de este modo:

		import pynter

		cadena = "0000100110011101011101000"

		salida = pynter.pinta_cuadro(cadena)

		salida.save("cuadro.png")
