Grayscale/Binary images using PIL

gistfile1.py

im=Image.open("1.jpg")
#im=im.rotate(1)
im.save("e.jpg")
im2=im.convert("L")
im2.save("b.jpg")
threshold = 100
im = im2.point(lambda p: p > threshold and 255)
im.save("d.jpg")
img="d.jpg"
result = tesseract.ProcessPagesWrapper(img,api)
print result

Hi, can you please explain to me lines number 6 and 7 ? Thank you

Have a look at the documentation: Image.point.
