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

Looks like PILlow may have changed tostring() to tobytes(). When trying to extract RGBA pixels to get them into an OpenGL texture, the following worked for me (within the glTexImage2D call which I omit for brevity).

from PIL import Image
img = Image.open("mandrill.png").rotate(180).transpose(Image.FLIP_LEFT_RIGHT)

# use img.convert("RGBA").tobytes() as texels
