python get pixel values from image
from PIL import Image

imgdata = img.getdata()

for item in imgdata:
if (x_pos) == imgWidth:

y_pos += 1
else:
x_pos += 1
if item[3] != 0:
pixel_value.append(item[2])
x.append(x_pos)

pixel_value, x, y = zip(*sorted(zip(pixel_value, x, y), reverse=True))
print(f'{pixel_value}n{x}n{y}')
