parser = argparse.ArgumentParser(description='viff reader example')
parser.add_argument('--file', type=str, help='filename (default=None)')
parser.add_argument('--save', action='store_true', help='save a copy as testing.xv')
args = parser.parse_args()
""" Read a file """
data = viff.read(args.file)
plt.imshow(data[0,0,:,:])
plt.show()
Write a new file
if args.save:
""" Write a new file """
