Getting list of pixel values from PIL

Question

Guys, I\'m looking for a bit of assistance. I\'m a newbie programmer and one of the problems I\'m having at the minute is trying to convert a black & white .jpg

Answer 1

data = numpy.asarray(im)

Notice：In PIL, img is RGBA. In cv2, img is BGRA.

My robust solution:

def cv_from_pil_img(pil_img):
    assert pil_img.mode=="RGBA"
    return cv2.cvtColor(np.array(pil_img), cv2.COLOR_RGBA2BGRA)
