Convert image to ascii art
import sys; from PIL import Image; import numpy as np
chars = np.asarray(list(' .,:;irsXA253hMHGS#9B&@'))
if len(sys.argv) != 4: print( 'Usage: ./asciinator.py image scale factor' ); sys.exit()
f, SC, GCF, WCF = sys.argv[1], float(sys.argv[2]), float(sys.argv[3]), 7/4
img = Image.open(f)
S = ( round(img.size[0]*SC*WCF), round(img.size[1]*SC) )
img = np.sum( np.asarray( img.resize(S) ), axis=2)
