Answer 1

Just an example if you want to save your 'raw' image to 'png' file (each pixel 32 bit, colored image):

import numpy as np
import matplotlib.pyplot as plt

img = np.fromfile("yourImage.raw", dtype=np.uint32)
print img.size #check your image size, say 1048576
#shape it accordingly, that is, 1048576=1024*1024
img.shape = (1024, 1024)

plt.imshow(img)
plt.savefig("yourNewImage.png")
