from PIL import Image

im = Image.open('picture\\haha.png' )#当前目录创建picture文件夹

Lim = im.convert('L' )
Lim.save('pice.jpg' )
# setup a converting table with constant threshold
threshold = 185
table = []
for i in range(256):
if i < threshold:
table.append(0)

table.append(1)
# convert to binary image by the table
bim = Lim.point(table, '1' )
bim.save('picf.png' )
